Evidence-Based Protocol
Supplement stack ranked by research quality
Primary Stack (Tier 1)
First-line treatment for pregnancy nausea; safe and effective; often combined with doxylamine
Reduces nausea; safe in pregnancy; evidence supports effectiveness for pregnancy-related nausea
Supporting Stack (Tier 2)
Critical supplementation to prevent Wernicke encephalopathy from prolonged vomiting and malnutrition
Replaces electrolytes lost through vomiting; prevents dehydration and imbalances
May become depleted with prolonged vomiting and malabsorption
Essential for fetal development; must be maintained despite inability to eat
Comprehensive nutrition support; may need to switch to smaller or chewable forms
Iron often worsens nausea; temporarily using iron-free prenatal may improve tolerance
Often depleted from vomiting; supports muscle function and may help with nausea
How It Works
Hyperemesis gravidarum (HG) is severe nausea and vomiting during pregnancy that goes beyond typical "morning sickness." It causes dehydration, weight loss (>5% of pre-pregnancy weight), electrolyte imbalances, and can require hospitalization. HG affects about 0.5-2% of pregnancies and usually begins around weeks 4-6, peaks at 9-13 weeks, and improves by week 20 for most women (though some have symptoms throughout pregnancy).
CRITICAL: Hyperemesis gravidarum requires medical care. If you cannot keep down fluids, are losing weight, urinating very little, or feeling faint, seek medical attention. Treatment may include:
THIS IS NOT "JUST MORNING SICKNESS." HG is a serious condition that can affect you and your baby. Don't suffer in silence.
* Vitamin B6 (Pyridoxine) is the first-line supplement for pregnancy nausea. It's safe and effective. Often combined with doxylamine (antihistamine) as prescription Diclegis/Bonjesta.
* Ginger has been studied in multiple trials for pregnancy nausea and shown to be safe and effective. Can be taken as capsules, tea, or candies.
* Thiamine (B1) supplementation is CRITICAL in HG. Prolonged vomiting can cause thiamine deficiency, leading to Wernicke encephalopathy (a neurological emergency). All HG patients should receive thiamine.
* Electrolyte replacement addresses losses from vomiting.
* Prenatal vitamins: If standard prenatals worsen nausea, switch to iron-free, gummy, or smaller formulations. Don't stop taking prenatals - work with your provider to find a tolerable form.
Expected timeline: Many women feel improvement by weeks 16-20. Supplements help manage symptoms but don't "cure" HG. The condition runs its course with proper supportive care.

Weight Loss & Maintenance
1 shared supplement · 433 outcomes
This goal refers to people with a BMI >25 attempting to reach/maintain their ideal weight. While interventions that work for people with a BMI >25 may also work for people with a lower BMI, the context is often sufficiently different that this isn't assured.
Vertigo
1 shared supplement · 2 outcomes
Vertigo is the sensation of spinning or dizziness without any associated movement. It can be caused by conditions of the inner ear (which plays an important role in balance) or neurological conditions.
Type 2 Diabetes
1 shared supplement · 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.
Surgical Recovery
1 shared supplement · 43 outcomes
Surgical recovery refers to physiological endpoints after surgery including recovery time and adverse events including morbidity and mortality, as well as the presence of physical pain, physical comfort with everyday activities, physical independence, psychological support, and emotional well-being.
Primary Dysmenorrhea (Menstrual Cramps)
1 shared supplement · 28 outcomes
Routine menstrual cramps are clinically called primary dysmenorrhea. Primary dysmenorrhea is menstrual pain not caused by other underlying conditions or diseases. If there is an underlying condition, such as endometriosis, that diagnosis is referred to as secondary dysmenorrhea.

Pneumonia
1 shared supplement · 10 outcomes
Pneumonia is an infection that inflames the air sacs and lower airways of the lungs, causing them to fill with fluid. Signs and symptoms of pneumonia include fever and chills, difficulty breathing, fatigue, and cough (with or without mucus). Cases caused by bacteria are treated with antibiotics.
Overweight
