What the AI looks for in Alfalfa Herbal Supplements

Plant part: Choose leaf or aerial-part products, not seed or sprout concentrates. Seeds and sprouts carry more L-canavanine, which has been linked to lupus-like reactions.
Vitamin K awareness: Check with your prescriber if you take a vitamin K antagonist. Alfalfa can blunt the effect of warfarin.
Contaminant testing: Prefer brands that test for heavy metals and microbes. This is a bulk leafy crop sold as whole powder.

Brands that matter

NOW Foods: Budget alfalfa tablets.
Nature's Way: Alfalfa leaf capsules.

What to avoid

Alfalfa seed or sprout concentrates
Taking it alongside warfarin without medical advice
