Alfalfa Grass
Also known as: Medicago sativa, lucerne, alfalfa hay, alfalfa haylage, alfalfa-grass hay
Effective Dosage
No established dose
What the Science Says
Alfalfa grass is a flowering legume plant commonly used as animal feed. The available research covers its use as a dietary component in cattle, dairy cows, and other livestock — not in human clinical trials. No data from the provided studies supports specific health benefits for people taking alfalfa grass as a supplement.
What It Doesn't Do
No evidence it detoxifies your body. No proof it boosts immunity in humans. No clinical data showing it improves digestion, energy, or nutrient absorption in people. The research available is entirely in livestock, not humans.
Evidence-Based Benefits
In the provided studies, alfalfa grass appears exclusively as a forage/feed component in livestock and veterinary research, not as a human supplement. It was used as a roughage source in cattle, heifer, and veal calf diets (PMIDs: 27695780, 26440344, 25023798, 23989870, 28727093). One study noted that moldy alfalfa-grass hay caused hepatogenous photosensitization and liver enzyme elevations in calves, suggesting potential toxicity under certain conditions (PMID: 7571359).

Absorption & Bioavailability
Unknown — no human bioavailability data in the provided studies
Red Flags to Watch For
- All provided research involves livestock (cattle, dairy cows, antelope), not human clinical trials — benefits cannot be extrapolated to people
- Moldy alfalfa-grass hay has been linked to liver disease (hepatogenous photosensitization) in cattle, raising concerns about product quality and storage
- High-selenium alfalfa hay caused significant selenium accumulation in liver and kidney tissue of animals — selenium toxicity is a real risk if sourced from selenium-rich soils
- Over 1,000 supplement products contain this ingredient despite a complete absence of human clinical trial evidence in the provided data
