What the Science Says
Alfalfa grass is a flowering legume plant traditionally used as livestock forage and hay. In the provided research, it appears exclusively as a background dietary component in animal studies — fed to cattle, heifers, and antelope — not as a tested supplement ingredient. No human clinical trials on alfalfa grass as a supplement were found in the provided data. Any health claims made about alfalfa grass supplements for humans are not supported by the studies reviewed.
What It Doesn't Do
No evidence it detoxifies your body. No proof it boosts immunity in humans. No clinical data showing it lowers cholesterol or blood sugar in people. Not shown to improve digestion or gut health in any human trial. The 'superfood' label is marketing, not science.
Absorption & Bioavailability
Unknown — no human pharmacokinetic or absorption data in the provided studies
Red Flags to Watch For
- Moldy alfalfa hay has been linked to liver disease (hepatogenous photosensitization) in cattle, raising questions about quality control in raw plant supplements
- High-selenium alfalfa hay caused significant selenium accumulation in animal organs — selenium toxicity is a real risk if sourcing or processing is poor
- All provided research was conducted in livestock (cattle, antelope), not humans — zero human clinical trials support supplement use
- Widely sold in supplement form despite a complete absence of human efficacy data in the reviewed literature
