Prenatal supplements are completely inadequate in providing vital nutrients while pregnant – and most girls usually are not even aware of it

If there may be one thing doctors agree on, it’s that each one of their pregnant patients should take prenatal supplements. As a result, about 3 out of 4 expectant moms Follow your doctor’s advice.

But although they’re equally vital for the health of mother and child, Prenatal supplements usually are not regulatedThere are not any regulations that require these supplements to contain any nutrients in any respect, let alone the suitable doses.

Not surprisingly, research shows that none of essentially the most widely available over-the-counter prenatal supplements – whether tablets, capsules, softgels or gummy bears – provide sufficient amounts of 5 vital nutrients: Folic acid, iron, vitamin D, calcium and Docosahexaenoic acida member of the omega-3 fatty acid family.

All these nutrients are really helpful by the American College of Obstetricians and Gynecologistsand sufficient intake of those substances is related to improved health outcomes for each pregnant patients and their babies.

As an assistant doctor for general medicine with a Ph.D. in NutritionI started researching these products after my patients asked questions on them. I discovered that most of the vital nutrients needed while pregnant is missing from these productsOther dietary supplements, nevertheless, contained too little or an excessive amount of.

It is best to start out taking prenatal supplements while you resolve to have a toddler.

Folic acid

Folic acid, which reduces the speed of birth defects by 50%is the important reason for the event of prenatal supplements.

But folic acid only prevents birth defects if taken before day 28 of pregnancy. In other words, certain birth defects can only be prevented if a lady takes a prenatal complement before she knows she is pregnant.

For this reason, the American College of Obstetrics and Gynecology recommends that ladies should begin taking prenatal supplements no less than three months before pregnancy.

However, only about one third of ladies – and only 10% of African-American women. For them, folic acid, which is presupposed to prevent birth defects, comes too late.

Even women who take supplements early in pregnancy will not be getting the nutrients they need, including 400 micrograms of folic acid — an artificial version of folate — from their every day prenatal complement. 27% of prenatal supplements contain less than this amount.

On the opposite hand, while rare, it isn’t not possible to seek out products containing greater than 1 milligram of folic acid – a potentially dangerous amount that has been linked to impaired cognitive development, especially reduced verbal skills.

Omega-3 fatty acids

After their Introduction within the Eighties as a straightforward multivitamin with some extra folic acid, prenatal supplements have evolved to offer an additional dietary boost. One of those supplements, omega-3 fatty acids, function constructing blocks for the development of the fetal brain. In fact, 40% of the human brain consists of omega-3 fatty acids.

A study on rats showed that insufficient intake of omega-3 fatty acids while pregnant results in significant decrease in omega-3 levels within the mother's brain. Although such a study could never be conducted in humans, it suggests that moms may forgo omega-3 fatty acids from their very own brains to support their baby's brain development.

But other studies linking low values of omega-3 fatty acids in postpartum depressionthe intellect of a toddler or other significant results have produced mixed results.

However, there appears to be a connection between Omega-3 fatty acids and premature birthswith increased intake resulting in reduced risk. Premature birth – Delivery before the thirty seventh week of pregnancy – is coming within the US and worldwide, with greater than 1 in 10 babies born prematurely.

New guidelines recommend that pregnant women who don’t frequently devour enough omega-3 fatty acids should devour 600 to 1,000 milligrams of omega-3 fatty acids every day. Studies have shown that that is sort of not possible to be present in a prenatal complement.

However, patients who eat fatty fish twice every week – this will be salmon, mackerel, herring, sardines or anchovies – may only need a further 100-200 milligrams every day Omega-3 fatty acids while pregnantAnd about 40% of business prenatal supplements provide this amount.

But most Americans don’t eat two servings of fatty fish per week. 95% of pregnant and breastfeeding women within the US You usually are not getting enough omega-3 fatty acidsWhile many ladies avoid fish while pregnant because of Concerns about mercuryFatty fish that contain omega-3 fatty acids are low in mercury and usually are not among the many fish that needs to be avoided while pregnant.

Prenatal supplements, especially when taken before or early in pregnancy, may reduce the danger of autism within the child, especially in women who have already got a toddler with autism.


Choline can also be crucial for fetal brain development. Its requirement increases to 450 milligrams per day while pregnant and much more during breastfeeding – 550 milligrams per day.

With the exception of organ meats resembling beef liver, few foods contain enough choline to satisfy this need. One egg accommodates about 150 milligrams of choline, a 3-ounce steak accommodates 117, and a half-cup of soybeans accommodates 107. Salmon, broccoli, Brussels sprouts, cauliflower, green peas, and kidney beans also contain some choline.

Because these usually are not large amounts, pregnant women have to devour several choline-rich foods every day and may have a complement to achieve the really helpful amount.

But apparently this isn’t the case for nearly anyone: 95% of pregnant women ingest insufficient amounts of cholineand greater than half of prenatal supplements haven’t any cholineThose that do typically provide far too little of it – lower than 100 milligrams.

In addition, some research suggests that taking even higher amounts of choline than really helpful in guidelines may provide additional advantages.

A study showed that doubling the really helpful amount within the third trimester of pregnancy improve a toddler’s attention spanAnother study found that a few of the effects of fetal alcohol syndrome will be alleviated with 4 times the really helpful amount of choline.


These three examples clearly show that taking prenatal supplements is not any guarantee of a nutritionally adequate pregnancy.

Part of the issue is an absence of coaching: doctors are learned little or no about nutrition during my medical studiesand I've observed that the majority patients simply assume that they're getting every thing they need from their prenatal supplements.

Since there are not any regulatory standards for these products, there isn’t any incentive to enhance them. Nobody is forcing these corporations to alter their recipes, so it isn’t a priority for them.

My intention here isn’t to discredit these products, but quite to point out that they alone usually are not enough.

Finding one of the best complement with just the best amount of every nutrient – ​​not an excessive amount of and never too little – is difficult, if not not possible. Even the worth is no quality feature.

To ensure an adequate supply of those nutrients, pregnant women or those planning to grow to be pregnant should consider the next three things:

1) Choose a prenatal complement containing no more and at least the really helpful 400 micrograms of folic acid every day and take it three months before conception.

2) Eat two servings of fatty fish weekly and take a 100-200 mg omega-3 fatty acid complement every day. If you don't eat fatty fish frequently, take a 600-1,000 mg complement.

3) Assess current intake of choline-rich foods and consider taking a choline complement if needed.

Getting adequate nutrition while pregnant requires an incredible amount of effort and chances are you’ll feel like you might be on your personal to do it.

I give my patients a guide to assist them manage their dietary needs while pregnant. This may help provide the knowledge needed to beat the inadequacies of prenatal supplements.
