"With 27mg of iron per dose, this prenatal completely covers a pregnant woman's increased daily iron needs."

Nutrient needs are increased during pregnancy to support the growth and development of the fetus while also supporting the health of the mother. But with so many prenatal vitamins out there, how do you make the right choice? It is important to make sure prenatal supplements have been tested by third party labs and offer maximum transparency to consumers.

In addition to purity tests and transparency, it is important to consider the amounts of key prenatal nutrients—such as calcium, vitamin d, iron, folate and choline—that the supplement contains in each dose. Women may need to try a few different prenatal supplements before finding one that does not have undesired side effects, such as nausea or constipation.

Nausea and vomiting during pregnancy are common occurrences experienced by a large number of women. Ginger has been used for centuries as a herbal remedy for numerous ailments, including digestive issues such as nausea.

A systematic review examined the use of ginger for the treatment of nausea and vomiting during pregnancy and found that ginger significantly improved the symptoms of nausea when compared to a placebo. New Chapter’s Perfect Prenatal vitamin includes organic ginger in each dose to help ease nausea. This supplement is vegetarian, certified non-GMO, and gluten- and synthetic filler-free.

Best with DHA: Nordic Naturals

Docosahexaenoic acid (DHA) is one of the three main essential omega 3 fatty acids, the others being alpha-linolenic acid (ALA) and eicosapentaenoic acid (EPA). DHA is found primarily in seafood.

During pregnancy, DHA is especially important for a baby’s healthy cognitive and visual function and overall brain development. A reference intake for the amount of DHA that should be consumed per day hasn't been set yet, but health experts agree that pregnant and lactating women should consume at least 200 milligrams of DHA per day. Others believe that pregnant women should up their intake to 300 milligrams of DHA per day.

Nordic Naturals’ Prenatal DHA provides 480 milligrams of DHA and 205 milligrams of EPA per serving, and is the official omega-3 supplement of the American Pregnancy Association. All of Nordic Naturals products are non-GMO, use wild-caught fish, and are third-party tested, surpassing the strictest international standards for purity and freshness.

Best Gummy: Smarty Pants

Smarty Pants Prenatal gummy vitamins are free of artificial sweeteners, high fructose corn syrup, and the top eight allergens. Smarty Pants does not use synthetic colors or artificial flavors in their gummies, and each batch is third party tested for purity.

From one four-gummy serving, mothers-to-be will get 200 percent of their daily value for vitamin d and 100 percent of their daily value for folate. The supplement also contains pregnancy essentials like choline, and all eight b vitamins.

One serving contains 6 grams of added sugar, an important note if consumers have been instructed to watch their sugar intake during pregnancy. It is also important to note that the supplement does not contain iron, so it might be contraindicated for vegan or vegetarian mothers-to-be who depend on supplemental iron intake.

Best Organic: Garden of Life

Garden of Life’s myKind Prenatal vitamin is certified-organic by the USDA as well as certified non-GMO. The nutrients contained in this product are derived from an organic food blend. Unlike many other prenatals, this supplement’s serving size is one tablet, which is good news for anyone who dislikes swallowing pills. With 250 percent daily value for vitamin d and 200 percent daily value for folate, it's perfect for pregnant women looking for natural supplementation.

It's important to note, however, that the prenatal vitamin only contains 50 percent of the recommended daily intake of iron and does not contain choline, another critical nutrient for healthy fetus development, so consumers may need to use additional supplements if their diet is lacking in iron and choline consumption.

Given the lower amount of iron, this pick may be ideal for women who find supplemental iron to be constipating, but it's still important to make sure your increased iron needs are met through diet by speaking with a registered dietitian or physician.

Best Probiotic: MegaFlora Baby & Me

MegaFlora Probiotic for Baby & Me

 MegaFood

Research on probiotic supplementation has exploded in recent years. Though more research on the use of probiotics during pregnancy is needed, some studies suggest that supplementing with a probiotic can have a beneficial effect on depression and anxiety symptoms postpartum. Studies have also explored the use of probiotics to support the baby's immune system and prevent eczema and other allergies.

This product contains strain-specific probiotic bacteria that have been used in research studies, such as Lactobacillus rhamnosus (HN001). It also has ginger root to aid nausea and vomiting, and prebiotic fiber from dandelion and beetroot to feed the probiotics.

Megafood is one of the most trusted brands in the supplement industry because of their commitment to transparency. Consumers can head to Megafood’s website and observe product production live 24/7. Their products are certified glyphosate-, GMO-, soy-, gluten-, and dairy-free and have been tested for over 125 pesticides and herbicides.

Best with Folic Acid: Thorne

Adequate intake of folate is known to support healthy development of the fetus’s organs and tissues. In addition, it is especially critical for the closure of the neural tube, which is the precursor to the brain and spinal cord. Though many foods like cereal, bread and grains are enriched with folic acid (the synthetic form of folate that is used in supplements and fortified foods) and other b vitamins, supplementation is still recommended for pregnant women, as their need for this nutrient becomes 50 percent higher. 

It is recommended that women consume 600 micrograms of supplemental folic acid, in addition to the folate found in food. Thorne’s Basic Prenatal contains 1,000 micrograms of metabolically active folic acid—283 percent of the recommended daily intake for folate. In addition, this prenatal is gluten-, dairy-, soy-, and artificial flavor-free.

Thorne’s facility is NSF- and cGMP-compliant and they rigorously test for 760 contaminants to verify the identity, potency, and purity of each ingredient listed on their product labels.

Best with Iron: Rainbow Light

Rainbow Light Prenatal One Prenatal Vitamins

 Target

When you're pregnant, your iron needs increase by 50 percent—18 milligrams for adult women to 27 milligrams per day for pregnant adult women. The growing baby requires adequate iron to support the healthy growth of cells, tissues, and organs and mom needs extra iron to support the increase in blood volume when pregnant.

The extra red blood cells that are produced carry oxygen to the baby and, without enough iron, mom can develop iron-deficiency anemia which has been associated with increased risk of low-birth-weight infants, premature delivery, and infant mortality.

Rainbow Light’s Prenatal One contains 27 milligrams of iron per dose. This completely covers a woman’s needs, which is great news considering that many pregnant women in the United States only consume 15 milligrams of iron per day from their diet.

Unlike many prenatals that require multiple tablets per dose, this product comes in a single tablet serving size. When taking a supplement that contains iron, do not take it with coffee, tea, bran or milk as this can affect absorption.
