Preeclampsia
| Supplement | Amount | Why |
|---|---|---|
Calcium | 1,200 to 1,500 mg daily |  [3 stars] An analysis of double-blind trials found calcium supplementation to be highly effective in preventing preeclampsia. |
Arginine | Refer to label instructions |  [2 stars] In one study in which pregnant women at an increased risk of developing preeclampsia received either arginine or a placebo, the arginine group had a significantly lower incidence of preeclampsia compared with the placebo group. |
Coenzyme Q10 | 200 mg per day | [2 stars] In a double-blind study at women who were at high risk of developing preeclampsia, supplementing with coenzyme Q10 reduced the incidence of preeclampsia by 44%.
|
Folic Acid | 5 mg daily | [2 stars] Supplementing with folic acid and vitamin B6 may lower homocysteine levels. Elevated homocysteine damages the lining of blood vessels and can lead to preeclamptic symptoms. |
Fish Oil | Refer to label instructions |  [1 star] Fish oil supplementation may lower the incidence of preeclampsia. |
Magnesium | Refer to label instructions | [1 star] Magnesium supplementation has been shown to reduce the incidence of preeclampsia in high-risk women in one trial. |
Vitamin B2 | Refer to label instructions | [1 star] Women who are deficient in vitamin B2 (riboflavin) are more likely to develop preeclampsia than women with normal levels. Supplementation may correct a deficiency. |
Vitamin B6 | Refer to label instructions | [1 star] Supplementing with vitamin B6 and folic acid may lower homocysteine levels. Elevated homocysteine damages the lining of blood vessels and can lead to the preeclamptic symptoms. |
- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by some in the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
