Evidence-Based Protocol

Supplement stack ranked by research quality

Limited Evidence

Primary Stack (Tier 1)

Omega-3 Fatty AcidsB

2-3g EPA+DHA daily (EPA dominant for depression)

DHA depleted in pregnancy; supports brain health; some evidence for perinatal depression prevention/treatment

20 studies | 2,500 participants

Vitamin DC

2000-4000 IU daily (safe in pregnancy at these doses)

Deficiency common in pregnancy; associated with perinatal depression; supports mood

12 studies | 1,500 participants

Supporting Stack (Tier 2)

Folate/MethylfolateC

400-800mcg folate (or 400-800mcg methylfolate)

Already recommended in pregnancy; may help with depression in those with MTHFR variants

8 studies | 500 participants

IronC

Based on need; typically 27-60mg elemental iron daily if deficient

Anemia common in pregnancy; iron deficiency associated with depression symptoms

8 studies | 600 participants

ProbioticsC

10-20 billion CFU daily

Gut-brain axis support; some evidence for mood improvement in pregnancy

6 studies | 400 participants

B-Complex VitaminsC

Prenatal vitamin with adequate B vitamins

B vitamins support neurotransmitter synthesis; B6 and B12 particularly relevant for mood

6 studies | 400 participants

How It Works

Perinatal depression includes depression during pregnancy (prenatal/antenatal depression) and after delivery (postpartum depression). It affects 10-20% of mothers and can significantly impact both mother and baby.

TYPES:

•Prenatal Depression: During pregnancy

•Postpartum Depression: After delivery (usually first year)

•Postpartum Psychosis: Rare, severe psychiatric emergency

•Baby Blues: Very common (80%), mild, resolves within 2 weeks

SYMPTOMS:

•Persistent sadness or emptiness

•Loss of interest in activities

•Sleep problems (beyond normal infant care disruption)

•Appetite changes

•Fatigue and low energy

•Difficulty bonding with baby

•Thoughts of harming self or baby (seek help immediately)

•Feeling like a bad mother

•Excessive worry about baby

RISK FACTORS:

•Previous depression or anxiety

•Stressful life events

•Lack of social support

•Relationship problems

•Unplanned pregnancy

•Pregnancy complications

•History of trauma

CRITICAL: Perinatal depression requires professional treatment. This protocol is SUPPORTIVE ONLY.

TREATMENT OPTIONS:

•Psychotherapy: CBT and interpersonal therapy very effective

•Medications: Some antidepressants safe during pregnancy/breastfeeding (discuss with doctor)

•Support groups: Peer support helpful

•Self-care: Sleep when possible, accept help, gentle exercise

SAFE IN PREGNANCY:

•Omega-3 fatty acids

•Vitamin D (at recommended doses)

•Folate

•Standard prenatal vitamins

AVOID OR USE WITH CAUTION:

•St. John's Wort (drug interactions, not well-studied in pregnancy)

•High-dose herbs

•Any supplement not discussed with provider

* Omega-3s (especially EPA) have the most evidence for perinatal depression.

* Vitamin D deficiency is associated with increased depression risk.

* Folate and B vitamins support neurotransmitter production.

Expected timeline: Supplements may provide modest benefit over 4-8 weeks. Psychotherapy and/or medication often needed for moderate-severe depression.

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.

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.

A stroke is a medical emergency. If you are experiencing stroke symptoms, call emergency medical services, even if they resolve quickly. This page does not discuss acute treatments for stroke, but rather focuses on mitigating the risk of having a stroke and supporting recovery from a stroke. Lifestyle and dietary habits that keep your blood pressure, blood sugar, cholesterol levels, and your weight in check, can help to reduce the risk of stroke.
