Evidence for 2 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Lactation support (galactagogue)

Limited Evidence

Small clinical studies suggest shatavari may modestly increase milk production in breastfeeding mothers. Evidence quality is limited and results vary.

Menopause symptoms

Mixed Evidence

Limited evidence from small studies suggests possible mild benefit; results are inconsistent.

How it works

Shatavari contains steroidal saponins (shatavarins), flavonoids, and oligosaccharides. The shatavarins are structurally similar to phytoestrogens and may modulate hormonal balance, while other components have antioxidant and anti-inflammatory activity in laboratory studies. Traditional Ayurvedic use describes it as 'rasayana' for women, supporting menstrual cycle regulation, fertility, lactation, and menopause. Small clinical studies suggest it may modestly support lactation in breastfeeding mothers (galactagogue effect), but evidence quality is limited.

Dosage

Traditional doses: 3-6 g powdered root daily, often with warm milk or honey. Standardized extracts are typically dosed 500-1500 mg/day.

When and how to take it

Traditionally taken once or twice daily with warm milk or water. For lactation support, often taken throughout the day. Can be taken with or without food.

Frequently asked questions

Is shatavari the same as the asparagus I eat?⌄

They are in the same genus but are different species. Asparagus racemosus (shatavari) is the medicinal species; Asparagus officinalis is the culinary vegetable. The active compounds and uses differ.

Will shatavari increase my milk supply?⌄

Some small studies suggest a modest benefit, but evidence is limited. Talk with a lactation consultant or clinician before relying on it - many factors affect milk supply.
