Preeclampsia

Preeclampsia is a complication of pregnancy characterized by new-onset high blood pressure accompanied by evidence of organ injury. It typically manifests in the last few months of pregnancy, often requiring early delivery. Preeclampsia can sometimes occur shortly after giving birth.

Evidence-Based Protocol

Supplement stack ranked by research quality

Strong Evidence

Primary Stack (Tier 1)

CalciumA
1000-2000mg daily (starting before 20 weeks)

High-dose calcium significantly reduces preeclampsia risk, especially in women with low dietary calcium intake

25 studies | 15,000 participants
Low-Dose AspirinA
81-150mg daily at bedtime (starting at 12-16 weeks)

Reduces preeclampsia risk by 17% when started before 16 weeks in high-risk women; affects prostaglandin balance

40 studies | 30,000 participants

Supporting Stack (Tier 2)

Vitamin DB
1000-4000 IU daily (based on blood levels)

Deficiency associated with increased preeclampsia risk; supplementation may reduce risk

15 studies | 5,000 participants
Omega-3 Fatty AcidsB
1-2g EPA+DHA daily

May improve endothelial function and reduce inflammation; modest evidence for preeclampsia prevention

12 studies | 3,000 participants
L-ArginineC
3-6g daily

Precursor to nitric oxide; may improve blood vessel function and reduce blood pressure

8 studies | 500 participants
Folic AcidC
800-5000mcg daily

Reduces homocysteine; may support endothelial function; higher doses studied for preeclampsia prevention

10 studies | 2,000 participants

How It Works

Preeclampsia is a serious pregnancy complication characterized by high blood pressure and protein in the urine, typically developing after 20 weeks of pregnancy. It can progress to eclampsia (seizures) or HELLP syndrome and is a leading cause of maternal and fetal morbidity and mortality. Prevention in high-risk women is a major focus of prenatal care.

CRITICAL: Preeclampsia is a medical emergency. This protocol is for PREVENTION in high-risk women, not treatment. If you develop symptoms (severe headache, visual changes, upper abdominal pain, sudden swelling), seek immediate medical care.

•Calcium supplementation is one of the most effective interventions for preventing preeclampsia. The WHO recommends 1.5-2g daily for pregnant women in populations with low calcium intake. A large Cochrane review found calcium reduces preeclampsia risk by about 55% and is most effective in women with low baseline calcium intake. Start early in pregnancy.
•Low-Dose Aspirin is recommended by ACOG and USPSTF for women at high risk of preeclampsia. When started at 12-16 weeks gestation and taken at bedtime, it reduces preeclampsia risk by about 17% and reduces severe preeclampsia and preterm birth. High-risk factors include previous preeclampsia, chronic hypertension, diabetes, kidney disease, or multiple gestation.
•Vitamin D deficiency is strongly associated with increased preeclampsia risk. Supplementation may help reduce risk, though evidence is still building. Given that vitamin D deficiency is common and supplementation is safe, correcting deficiency is prudent.
•Omega-3 Fatty Acids may help by reducing inflammation and improving blood vessel function. While evidence for preeclampsia prevention specifically is modest, omega-3s have other pregnancy benefits and are generally recommended.
•L-Arginine is a precursor to nitric oxide, which relaxes blood vessels. Some studies suggest it may help prevent preeclampsia by improving blood flow to the placenta, though evidence is limited and it's not a standard recommendation.
•Folic Acid at higher doses may help by reducing homocysteine levels and supporting endothelial function. While standard doses (400-800mcg) are recommended for all pregnancies, higher doses are being studied for preeclampsia prevention.

Who is high-risk: Previous preeclampsia, chronic hypertension, pregestational diabetes, kidney disease, autoimmune disease (lupus, antiphospholipid syndrome), multiple gestation (twins/triplets), first pregnancy, obesity, age >35.

Migraine Headache

6 shared supplements · 50 outcomes

Migraine headaches are usually one-sided (sometimes bilateral) head pain. They affect women more often than men, and can have a number of triggers, and are more common if you have a family member with migraines. They can be distinguished from other types of headaches (such as tension or cluster headaches) due to additional symptoms of nausea, vomiting, sensitivity to light and sound, and worsening of pain with activity.

Type 2 Diabetes

5 shared supplements · 868 outcomes

Type 2 diabetes (T2D) is a disease in which blood glucose levels are too high. It is characterized by insulin resistance in muscle, fat, and pancreas cells and an inability of the pancreas to manufacture enough insulin to control blood glucose levels. T2D is strongly associated with excess body fat, and weight loss induced by lifestyle changes is extremely effective for treating T2D.

Overweight

5 shared supplements · 379 outcomes

Overweight is characterized as having a body mass index (BMI) of 25 to 29.9. Having overweight is associated with increased risk of conditions such as cardiovascular disease. However, this may not be the case in people with increased lean mass (e.g., athletes or weight lifters).

Metabolic Syndrome

5 shared supplements · 391 outcomes

Metabolic syndrome refers to a group of cardiometabolic risk factors: abdominal obesity, high blood pressure, high fasting blood sugar, high blood triglycerides, and low HDL-C. If a person has at least three of these, they have metabolic syndrome.

Menopause

Menopause is the stage of life when menses permanently cease, and the reproductive system no longer performs functions related to fertility. A woman is considered to have entered menopause after menses have stopped for 12 months.

High Blood Pressure

5 shared supplements · 393 outcomes

High blood pressure is when the force of your blood pushing against the walls of the arteries is consistently too high. High blood pressure is often caused by an unhealthy lifestyle, although it can result from other medical conditions as well.
