What is it

Diosgenin is a steroidal sapogenin found in wild yam (Dioscorea villosa), fenugreek, and other plants. It is a starting material for industrial synthesis of steroid hormones (including progesterone and cortisone) but is not converted to those hormones in the human body.

Evidence for 2 uses

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

Menopausal symptoms (wild yam)

Mixed Evidence

Limited and mixed evidence for benefit. The common claim that wild yam creams provide natural progesterone is not supported by human biology.

Cholesterol / lipid profile

Mixed Evidence

Small preclinical and limited human studies suggest modest lipid effects; not strong enough to recommend as a treatment.

How it works

Diosgenin's chemical structure resembles cholesterol and steroid hormones, which led to claims that wild yam creams or supplements can act as 'natural progesterone.' This is a marketing myth: the human body lacks the enzymatic pathway to convert diosgenin into progesterone or other active steroid hormones. In laboratory studies, diosgenin has shown anti-inflammatory, lipid-lowering, and anti-cancer activity. Some small human studies suggest possible benefits for cholesterol and menopausal symptoms, but evidence is limited and effect sizes are small.

Dosage

No standardized dose. Wild yam supplements may contain extracts standardized to 5-25% diosgenin, typically dosed 200-1000 mg/day. Pure diosgenin doses are not well established.

When and how to take it

Oral supplements: take with meals to reduce stomach upset. No clear preference for time of day.

2 commercial forms

Compare the main delivery options and what they’re best suited for.

Wild yam extract (standardized to diosgenin)

Most common oral form.

Poorly water-soluble; absorption may be improved with fat.

Wild yam cream

Marketed for menopause; mechanism is unsupported unless cream contains actual progesterone.

Diosgenin does not penetrate intact skin in meaningful amounts and does not convert to progesterone topically.

Safety

Generally well tolerated at typical supplement doses. High doses may cause gastrointestinal upset. Quality varies between products; some 'wild yam progesterone creams' have been spiked with synthetic progesterone, an unapproved practice.

Who should be cautious

Avoid in pregnancy and breastfeeding. People with hormone-sensitive conditions should be cautious. Avoid creams marketed as 'natural progesterone' unless they actually contain pharmaceutical progesterone (in which case prescription oversight is appropriate).

Interactions

Theoretical interactions with hormone-related medications and anti-inflammatory drugs. May affect lipid-lowering medications via cholesterol-related pathways.

Frequently asked questions

Does wild yam cream raise progesterone levels?⌄

No. The human body does not have the enzymes to convert diosgenin into progesterone. Any progesterone effect from a 'wild yam cream' would come only if the product was actually spiked with progesterone hormone.

Is diosgenin safe?⌄

At typical supplement doses, yes. Avoid products with vague hormone claims, and avoid in pregnancy or with hormone-sensitive conditions.
