What Does Science Say About Depression During & After Pregnancy?

Author: Dr. Stephen Chaney

prevent postpartum depressionCan you help prevent postpartum depression by using omega-3s?  Pregnancy and breastfeeding should be a wonderful time in any woman’s life, but sometimes the dark days of depression take hold. Postpartum depression used to be taboo. It was never talked about unless a mother did something terrible enough to make it into the headlines. Nowadays we realize that it is nothing to be ashamed of. In fact, it is fairly common.

The CDC estimates that 11-20% of women will suffer some degree of depression after childbirth. A similar percentage of women will experience prenatal depression (depression during pregnancy). To put these numbers into perspective, 20% of women can expect to suffer depression during their lifetime.

Of course, that doesn’t make prenatal or postnatal (postpartum) depression any easier to understand for any woman who has suffered from it. How could such a joyous time in their lives lead to depression?

The causes of prenatal and postnatal depression are multifactorial. Some, such as genetic predisposition and hormonal imbalances, may be beyond a woman’s control. Others may require medical intervention.

However, many women ask: “Is there something natural, some change in diet and lifestyle, I could undertake that might help with the depression?” This week we will look at a study suggesting that omega-3s might help with prenatal and postnatal depression.

 

Can Omega-3s Help With Prevent Postpartum Depression?

can omega3 prevent postpartum depressionThere are several reasons for suspecting that omega-3s might help with both prenatal and postnatal (postpartum) depression.

  • Many studies have suggested that omega-3 deficiency is implicated in depression.
  • A recent study DHA During Pregnancy  reported that pregnant women in the US are only getting around 1/5 the recommended amount of omega-3s from their diet.
  • During the second and third trimester, the fetus requires tremendous amounts of omega-3s, particularly DHA, to support its developing brain. This could be another instance of the fetus robbing an important nutrient from the mother’s body.

However, clinical studies to date have been inconclusive. Some have shown a clear correlation between omega-3 deficiency and pre/postnatal depressions. Others have not.

The authors of this study (Lin et al, Biological Psychiatry, doi.org/10.1016/j.biopsych.2017.02.1182 ) did a meta-analysis of all studies measuring both omega-3 status and pre/postnatal depression. They included 12 studies with a total of 7739 women in their analysis. Of the women in the study 1094 (16.6%) suffered with prenatal and/or postnatal depression.

Their findings were:

  • Levels of total omega-3s and DHA were significantly lower in the women with prenatal and/or postnatal depression.
  • The ratio of omega-6 to omega-3 fatty acids was higher in the women with prenatal and/or postnatal depression.

 

What Does This Study Mean To You?

healthy livingThis study showed an association between omega-3 deficiency and depression during the prenatal and postnatal periods. It suggests, but does not prove, that omega-3 deficiency predisposes to pre/postnatal depression.  So, taking the recommended amounts of omega-3s may help prevent postpartum depression.

If this were the only reason to suggest adding extra omega-3s to your diet during pregnancy and lactation, it might not be sufficient to spur you to action. However, recent studies suggest that increasing your omega-3 intake during pregnancy and breastfeeding is also important for your child’s brain development. Thus, there are at least two important reasons to make sure your omega-3 intake is optimal during pregnancy and breastfeeding.

It is important to recognize that increasing your omega-3 intake may not be sufficient to cure pre- and postnatal depression by itself. It is probably best as part of a holistic approach. You should also:

  • Make sure you are getting adequate B vitamins (especially folic acid, B6 and B12). Clinical studies have also linked deficiencies of these nutrients with depression.
  • Make sure your protein intake is sufficient and limit sugars and simple carbohydrates. This helps stabilize blood sugar swings that can affect your mood.
  • Keep caffeine to a minimum and avoid alcohol.
  • Employ stress reduction techniques such as yoga, meditation, or conversations with friends.

Of course, there is nothing radical about any of these recommendations. These are the same recommendations every pregnant mother is being given for the health of their baby. For example, the importance of folic acid has been recognized for decades. The importance of omega-3s for your child’s brain development has received increasing recognition in recent years.

Finally, if natural approaches don’t work, consult your physician.

 

The Bottom Line

 

  • A recent meta-analysis has shown an association between omega-3 deficiency and both prenatal and postnatal depression.
  • That is significant in light of a recent study showing that pregnant women in the US are getting only 1/5 the recommended amount of omega-3s from their diet.
  • This study showed an association between omega-3 deficiency and depression during the prenatal and postnatal periods. It suggests, but does not prove, that omega-3 deficiency predisposes to pre/postnatal depression.
  • In addition, recent studies suggest that increasing your omega-3 intake during pregnancy and breastfeeding is also important for your child’s brain development. Thus, there is more than one reason to make sure your omega-3 intake is optimal during pregnancy and breastfeeding.
  • Increasing your omega-3 intake may not cure pre/postnatal depression by itself. It is probably best as part of a holistic approach. You should also:
    • Make sure you are getting adequate B vitamins (especially folic acid, B6 and B12).
    • Make sure your protein intake is sufficient and limit sugars and simple carbohydrates.
    • Keep caffeine to a minimum and avoid alcohol.
    • Employ stress reduction techniques such as yoga, meditation, or conversations with friends.
  • There are many other things that can contribute to depression. If natural approaches don’t work, you should consult your physician.

American Omega-3 Deficiency

Is There an American Omega-3 Deficiency?

Author: Dr. Stephen Chaney

omega 3 deficiencyOmega-3s have been controversial in recent years.  However, virtually everyone agrees that omega-3 intake in North American is low. But, would you believe that the United States and Canada are dead last with respect to omega-3 status – that we are among the countries with the lowest omega-3 status in the world? Is there an American omega-3 deficiency?  That is what a recent study suggests!

Omega-3 Deficiency in Americans

Previous studies have suggested that the American and Canadian diets were deficient in long chain omega-3s like EPA and DHA, but those studies were based on 24-hour diet recalls or food frequency surveys which might underrepresent the true amount of omega-3s in the diet. Therefore, a group of investigators from the United States and Canada decided to look at blood levels of EPA and DHA.

This study (Stark et al, Progress In Lipid Research, 63: 132-152, 2016) was a meta-analysis of 298 studies that recorded blood levels of EPA and DHA. These studies were from 36 counties and distinct regions around the world. They converted all of the measurements to a common unit expressed as percent by weight of EPA + DHA relative to the total weight of fatty acids in the blood.

American omega-3 deficiencyThey combined all studies from a given country or region to give an average value of percent EPA + DHA and then divided the countries and regions into four groupings based on the average weight percentage of EPA + DHA in the blood. If all that seems confusing, the figure on the right (taken from Stark et al, Progress In Lipid Research, 63: 132-152, 2016) should clear things up.

  • Red = very low (< 4%) EPA + DHA levels
  • Orange = low (4-6%) EPA + DHA levels
  • Yellow = moderate (6-8%) EPA + DHA levels
  • Green = adequate (>8%) EPA + DHA levels
  • Grey = no valid measurements in those countries

It is clear from this study that most Americans and most Canadians don’t do a very good job of incorporating omega-3 fatty acids into their diet, as several previous dietary surveys have suggested.  This could contribute to omega-3 deficiency.

Is The United States Dead Last In Omega-3 Status?

The global map of EPA + DHA blood levels certainly suggests that the United States is among a handful of countries with the very lowest omega-3 status. There are a few caveats, however.

  • As the large areas of grey indicate, there are a number of countries with no valid omega-3 blood measurements. The United States might have lots of company in the very low omega-3 status category.
  • There are some very large countries like Russia which have relatively few omega-3 blood measurements, and those measurements are only from a few regions of the country. The average omega-3 status for the entire country might be lower than indicated in this map.

On the other hand, there are lots of omega-3 blood measurements from countries like Japan, so it is clear that there are countries with much better omega-3 status than the United States.

What Does This Study Mean To You?

The important questions are, of course:Does it matter? What do these blood levels of EPA + DHA actually mean? Is < 4% EPA + DHA low enough to matter? What are the health consequences of low omega-3 status?  If you have an omega-3 deficiency, what are the risks?

Let’s start with the first question: How do we translate a blood level of EPA + DHA into how much we should be getting in our diet? While there is no established Dietary Reference Intake for EPA + DHA, several expert panels and international organizations have made recommendations for EPA + DHA intake. Those recommendations generally range from 250 mg/day to 500 mg/day for general health and 500 mg/day to 1,000 mg/day for heart health. Unfortunately, most people in the United States and Canada consume less than 200 mg/day of omega-3 fatty acids, and most of those are short chain omega-3s that are inefficiently converted to the long chain EPA and DHA.

More importantly, a recent study (Patterson et al, Nutrition Research, 35: 1040-1051, 2015) has examined how much additional EPA + DHA must be consumed by someone eating a typical North American diet to significantly improve their omega-3 status. It showed that:

  • 200 mg/day of EPA + DHA is required to improve omega-3 status from very low to low.
  • 500 mg/day of EPA + DHA is required to improve omega-3 status from very low to moderate.
  • 1250 mg/day of EPA + DHA is required to improve omega-3 status from very low to adequate.

omega-3 for heart healthIt is no surprise that these numbers correlate so well. My recommendation would be to consume at least 500 mg/day of EPA + DHA for general health and at least 1,000 mg/day for heart health.

Now let’s look at the last question: What are the health consequences of low omega-3 status? There are multiple health benefits associated with optimal omega-3 status, but the best evidence is for the beneficial effects of omega-3s on fetal and infant neurodevelopment and heart health. For example:

  • In case you have been confused by recent studies suggesting that omega-3s have no effect on heart health you should know that most of those studies were looking at the effect of EPA + DHA in patients who were already taking 3 or 4 heart medications. The studies actually concluded omega-3s provided no additional benefits in people already taking multiple heart medications. That is a totally different question.

Where Should You Get Your Omega-3s?

fish oil supplementsNow that you know how important the long chain omega-3s, EPA and DHA, are for your health, and you know that most of us have a very poor omega-3 status and therefore have an omega-3 deficiency , your next questions are likely to be: “What’s the best way to improve my omega-3 status?” and “Where can I find EPA and DHA in my diet?” The answer is complicated.

  • Cold water, oily fish like salmon are a great source of EPA and DHA. Unfortunately, our oceans are increasingly polluted and some of those pollutants are concentrated even more in farm raised fish. A few years ago a group of experts published a report in which they analyzed PCB levels in both wild caught and farm-raised fish from locations all around the world (Hites et al, Science 303: 226-229, 2004) . Based on PCB levels alone they recommended that some wild caught salmon be consumed no more than once a month and some farm raised salmon be consumed no more than once every other month!

Unfortunately, when you buy salmon in the grocery store or your favorite restaurant, you can ask whether the salmon is wild or farm-raised, but you have no idea where the salmon came from. You have no idea how safe it is to eat. I love salmon and still eat it on occasion, but not nearly as frequently as I used to.

As an aside, the buzzword nowadays is sustainability. I support sustainability. However, the easiest way to assure that fish are sustainable is to raise them in fish farms. When a waiter tells me how sustainable the “catch of the day” is, I ask them how polluted it is. If they can’t answer, I don’t buy it. My health is more important to me than sustainability.

  • Nuts, seeds, and canola oil are good sources of ALA, a short chain omega-3 fatty acid. These food sources are less likely to be contaminated, but the efficiency of conversion of ALA to EPA and DHA is only around 5-10%. In other words, you need to eat a lot of ALA-rich foods to enjoy the health benefits associated with EPA and DHA.
  • That leaves fish oil supplements, but you need to remember that the EPA + DHA supplements you purchase in the health food store come from polluted fish. Unfortunately, many manufacturers have inadequate purification and quality control standards. In other words, neither you nor they know whether their omega-3 products are pure. You need to make sure that the omega-3 supplement you purchase is made by a manufacturer with stringent quality control standards.

 

The Bottom Line

 

  • A recent study has shown that most Americans are deficient in long chain omega-3s like EPA and DHA. In fact, the mainland United States and Canada were tied with half a dozen other countries for the lowest omega-3 status in the world.  Omega-3 deficiency in Americans seems to be the worst.
  • That is unfortunate because recent studies have shown that optimal blood levels of EPA and DHA are associated with a number of health benefits, especially fetal and infant neurodevelopment and heart health.
  • Other studies suggest that most Americans should consume an extra 500 mg/day of EPA + DHA for general health and at least 1,000 mg/day for heart health.
  • Unfortunately, it is not easy get those levels of EPA and DHA from our diet:
  • Oily, cold water fish are a great source of EPA and DHA, but our oceans are increasingly polluted and experts recommend that some fish that are the best sources of EPA and DHA be consumed no more than once a month. The situation is even worse for farm-raised fish.
  • Of course, nowadays the buzzword for fish is sustainability, but sustainability does not guarantee purity. Sustainable fish can be just as polluted as the worst of the farm raised fish.
  • seeds and canola oil are great sources for ALA, a short chain omega-3 fatty acid. This source of omega-3s is less likely to be contaminated, but the efficiency of conversion of ALA to EPA and DHA in our bodies is only around 5-10%.
  • Fish oil supplements can be a convenient source of the EPA and DHA you need, but the fish oil often comes from polluted fish and many manufacturers have inadequate purification methods and quality control standards. If you choose fish oil supplements as your source of omega-3s, be sure to choose a manufacturer with stringent quality control standards. Otherwise, neither you nor the manufacturer will know whether their omega-3 supplement is pure.

Does Magnesium Optimize Vitamin D Levels?

Posted February 12, 2019 by Dr. Steve Chaney

The Case For Holistic Supplementation

Author: Dr. Stephen Chaney

 

Does magnesium optimize vitamin D levels?

magnesium optimize vitamin dOne of the great mysteries about vitamin D is the lack of correlation between vitamin D intake and blood levels of its active metabolite, 25-hydroxyvitamin D. Many people who consume RDA levels of vitamin D from foods and/or supplements end up with low blood levels of 25-hydroxyvitamin D. The reason(s) for this discrepancy between intake of vitamin D and blood levels of its active metabolite are not currently understood.

Another great mystery is why it has been so difficult to demonstrate benefits of vitamin D supplementation. Association studies show a strong correlation between optimal 25-hydroxyvitamin D levels and reduced risk of heart disease, cancer, and other diseases. However, placebo-controlled clinical trials of vitamin D supplementation have often come up empty. Until recently, many of those studies did not measure 25-hydroxyvitamin D levels. Could it be that optimal levels of 25-hydroxyvitamin D were not achieved?

The authors of the current study hypothesized that optimal magnesium status might be required for vitamin D conversion to its active form. You are probably wondering why magnesium would influence vitamin D metabolism. I had the same question.

The authors pointed out that:

  • Magnesium status affects the activities of enzymes involved in both the synthesis and degradation of 25-hydroxyvitamin D.
  • Some clinical studies have suggested that magnesium intake interacts with vitamin D intake in affecting health outcomes.
  • If the author’s hypothesis is correct, it is a concern because magnesium deficiency is prevalent in this country. In their “Fact Sheet For Health Professionals,” the NIH states that “…a majority of Americans of all ages ingest less magnesium from food than their respective EARs [Estimated Average Requirement]; adult men aged 71 years and older and adolescent females are most likely to have low intakes.” Other sources have indicated that magnesium deficiency may approach 70-80% for adults over 70.

If the author’s hypothesis that magnesium is required for vitamin D activation is correct and most Americans are deficient in magnesium, this raises some troubling questions.

  • Most vitamin D supplements do not contain magnesium. If people aren’t getting supplemental magnesium from another source, they may not be optimally utilizing the vitamin D in the supplements.
  • Most clinical studies involving vitamin D do not also include magnesium. If most of the study participants are deficient in magnesium, it might explain why it has been so difficult to show benefits from vitamin D supplementation.

Thus the authors devised a study (Q Dai et al, American Journal of Clinical Nutrition, 108: 1249-1258, 2018 ) to directly test their hypothesis.

 

How Was The Study Designed?

magnesium optimize vitamin d studyThe authors recruited 180 volunteers, aged 40-85, from an ongoing study on the prevention of colon cancer being conducted at Vanderbilt University. The duration of the study was 12 weeks. Blood was drawn at the beginning of the study to measure baseline 25-hydroxyvitamin D levels. Three additional blood draws to determine 25-hydroxyvitamin D levels were performed at weeks 1, 6, and 12.

Because high blood calcium levels increase excretion of magnesium, the authors individualized magnesium intake based on “optimizing” the calcium to magnesium ratio in the diet rather than giving everyone the same amount of magnesium. The dietary calcium to magnesium ratio for most Americans is 2.6 to 1 or higher. Based on their previous work, they considered an “ideal” calcium to magnesium ratio to be 2.3 to 1. The mean daily dose of magnesium supplementation in this study was 205 mg, with a range from 77 to 390 mg to achieve the “ideal” calcium to magnesium ratio. The placebo was an identical gel capsule containing microcrystalline cellulose.

Two 24-hour dietary recalls were conducted at baseline to determine baseline dietary intake of calcium and magnesium. Four additional 24-hour dietary recalls were performed during the 12-week study to assure that calcium intake was unchanged and the calcium to magnesium ratio of 2.3 to 1 was achieved.

In short this was a small study, but it was very well designed to test the author’s hypothesis.

 

Does Magnesium Optimize Vitamin D Levels?

 

does magnesium optimize vitamin d levelsThis was a very complex study, so I am simplifying it for this discussion. For full details, I refer you to the journal article (Q Dai et al, American Journal of Clinical Nutrition, 108: 1249-1258, 2018).

The most significant finding was that magnesium supplementation did affect blood levels of 25-hydroxyvitamin D. However, the effect of magnesium supplementation varied depending on the baseline 25-hydroxyvitamin D level at the beginning of the study.

  • When the baseline 25-hydroxyvitamin D was 20 ng/ml or less (which the NIH considers inadequate), magnesium supplementation had no effect on 25-hydroxyvitamin D levels.
  • When the baseline 25-hydroxyvitamin D was 20-30 ng/ml (which the NIH considers the lower end of the adequate range), magnesium supplementation increased 25-hydroxyvitamin D levels.
  • When the baseline 25-hydroxyvitamin D level approached 50 ng/ml (which the NIH says may be “associated with adverse effects”), magnesium supplementation lowered 25-hydroxyvitamin D levels.

The simplest interpretation of these results is:

  • When vitamin D intake is inadequate, magnesium cannot magically create 25-hydroxyvitamin D from thin air.
  • When vitamin D intake is adequate, magnesium can enhance the conversion of vitamin D to 25-hydroxyvitamin D.
  • When vitamin D intake is too high, magnesium can help protect you by lowering 25-hydroxyvitamin D levels.

The authors concluded: “Our findings suggest that optimal magnesium status may be important for optimizing 25-hydroxyvitamin D status. Further dosing studies are warranted…”

 

What Does This Study Mean For You?

magnesium optimize vitamin d for youThis was a groundbreaking study that has provided novel and interesting results.

  • It provides the first evidence that optimal magnesium status may be required for optimizing the conversion of vitamin D to 25-hydroxyvitamin D.
  • It suggests that optimal magnesium status can help normalize 25-hydroxyvitamin D levels by increasing low levels and decreasing high levels.

However, this was a small study and, like any groundbreaking study, has significant limitations. For a complete discussion of the limitations and strengths of this study I refer you to the editorial (S Lin and Q Liu, American Journal of Clinical Nutrition, 108: 1159-1161, 2018) that accompanied the study.

In summary, this study needs to be replicated by larger clinical studies with a more diverse study population. In order to provide meaningful results, those studies would need to carefully control and monitor calcium, magnesium, and vitamin D intake. There is also a need for mechanistic studies to better understand how magnesium can both increase low 25-hydroxyvitamin D levels and decrease high 25-hydroxyvitamin D levels.

However, assuming the conclusions of this study to be true, it has some interesting implications:

  • If you are taking a vitamin D supplement, you should probably make sure that you are also getting the DV (400 mg) of magnesium from diet plus supplementation.
  • If you are taking a calcium supplement, you should check that it also provides a significant amount of magnesium. If not, change supplements or make sure that you get the DV for magnesium elsewhere.
  • I am suggesting that you shoot for the DV (400 mg) of magnesium rather than reading every label and calculating the calcium to magnesium ratio. The “ideal” ratio of 2.3 to 1 is hypothetical at this point. A supplement providing the DV of both calcium and magnesium would have a calcium to magnesium ratio of 2.5, and I would not fault any manufacturer for providing you with the DV of both nutrients.
  • If you are taking high amounts of calcium, I would recommend a supplement that has a calcium to magnesium ratio of 2.5 or less.
  • If you are considering a magnesium supplement to optimize your magnesium status, you should be aware that magnesium can cause gas, bloating, and diarrhea. I would recommend a sustained release magnesium supplement.
  • Finally, whole grains and legumes are among your best dietary sources of magnesium. Forget those diets that tell you to eliminate whole food groups. They are likely to leave you magnesium-deficient.

Even if the conclusions of this study are not confirmed by subsequent studies, we need to remember that magnesium is an essential nutrient with many health benefits and that most Americans do not get enough magnesium in their diet. The recommendations I have made for optimizing magnesium status are common-sense recommendations that apply to all of us.

 

The Case For Holistic Supplementation

 

magnesium optimize vitamin d case for holistic supplementationThis study is one of many examples showing that a holistic approach to supplementation is superior to a “magic bullet” approach where you take individual nutrients to solve individual problems. For example, in the case of magnesium and vitamin D:

  • If you asked most nutrition experts and supplement manufacturers whether it is important to provide magnesium along with vitamin D, their answer would likely be “No”. Even if they are focused on bone health, they would be more likely to recommend calcium along with vitamin D than magnesium along with vitamin D.
  • If your doctor has tested your 25-hydroxyvitamin D levels and recommended a vitamin D supplement, chances are they didn’t also recommend that you optimize your magnesium status.
  • Clinical studies investigating the benefits of vitamin D supplementation never ask whether magnesium intake is optimal.

That’s because most doctors and nutrition experts still think of nutrients as “magic bullets.” I cover holistic supplementation in detail in my book “Slaying The Supplement Myths.”  Other examples that make a case for holistic supplementation that I cover in my book include:

  • A study showing that omega-3 fatty acids and B vitamins may work together to prevent cognitive decline. Unfortunately, most studies looking at the effect of B vitamins on cognitive decline have not considered omega-3 status and vice versa. No wonder those studies have produced inconsistent results.
  • Studies looking at the effect of calcium supplementation on loss of bone density in the elderly have often failed to include vitamin D, magnesium, and other nutrients that are needed for building healthy bone. They have also failed to include exercise, which is essential for building healthy bone. No wonder some of those studies have failed to find an effect of calcium supplementation on bone density.
  • A study reported that selenium and vitamin E by themselves might increase prostate cancer risk. Those were the headlines you might have seen. The same study showed Vitamin E and selenium together did not increase prostate cancer risk. Somehow that part of the study was never mentioned.
  • A study reported that high levels of individual B vitamins increased mortality slightly. Those were the headlines you might have seen. The same study showed that when the same B vitamins were combined in a B complex supplement, mortality decreased. Somehow that observation never made the headlines.
  • A 20-year study reported that a holistic approach to supplementation produced significantly better health outcomes.

In summary, vitamins and minerals interact with each other to produce health benefits in our bodies. Some of those interactions we know about. Others we are still learning about. When we take high doses of individual vitamins and minerals, we create potential problems.

  • We may not get the full benefit of the vitamin or mineral we are taking because some other important nutrient(s) may be missing from our diet.
  • Even worse, high doses of one vitamin or mineral may interfere with the absorption or enhance the excretion of another vitamin or mineral. That can create deficiencies.

The same principles apply to our diet. I mentioned earlier that whole grains and legumes are among the best dietary sources of magnesium. Eliminating those two foods from the diet increases our risk of becoming magnesium deficient. And, that’s just the tip of the iceberg. Any time you eliminate foods or food groups from the diet, you run the risk of creating deficiencies of nutrients, phytonutrients, specific types of fiber, and the healthy gut bacteria that use that fiber as their preferred food source.

The Bottom Line

 

A recent study suggests that optimal magnesium status may be important for optimizing 25-hydroxyvitamin D status. This is one of many examples showing that a holistic approach to supplementation is superior to a “magic bullet” approach where you take individual nutrients to solve individual problems. For example, in the case of magnesium and vitamin D:

  • If you asked most nutrition experts and supplement manufacturers whether it is important to provide magnesium along with vitamin D, their answer would likely be “No.”  Even if they are focused on bone health, they would be more likely to recommend calcium along with vitamin D than magnesium along with vitamin D.
  • If your doctor has tested your 25-hydroxyvitamin D levels and recommended a vitamin D supplement, chances are he or she did not also recommend that you optimize your magnesium status.
  • Clinical studies investigating the benefits of vitamin D supplementation never ask whether magnesium intake is optimal. That may be why so many of those studies have failed to find any benefit of vitamin D supplementation.

I cover holistic supplementation in detail in my book “Slaying The Supplement Myths” and provide several other examples where a holistic approach to supplementation is superior to taking individual supplements.

In summary, vitamins and minerals interact with each other to produce health benefits in our bodies. Some of those interactions we know about. Others we are still learning about. Whenever we take high doses of individual vitamins and minerals, we create potential problems.

  • We may not get the full benefit of the vitamin or mineral we are taking because some other important nutrient(s) may be missing from our diet.
  • Even worse, high doses of one vitamin or mineral may interfere with the absorption or enhance the excretion of another vitamin or mineral. That can create deficiencies.

The same principles apply to what we eat. For example, whole grains and legumes are among the best dietary sources of magnesium. Eliminating those two foods from the diet increases our risk of becoming magnesium deficient. And, that’s just the tip of the iceberg. Any time you eliminate foods or food groups from the diet, you run the risk of creating deficiencies.
