What is it? / Overview
Wheatgrass contains chlorophyll, flavonoids, and vitamins with antioxidant activity in laboratory assays, but proposed anticancer and antioxidant effects have not been demonstrated in human clinical trials -- it's best regarded as a nutrient-dense food-like product, not a therapeutic agent.
How is it used? / Administration
Form: Wheatgrass (Triticum aestivum) juice, juice powder, or tablets
Typical dose studied: No validated clinical dose
Timing: Not established
Though the grass itself is gluten-free in principle, cross-contamination with wheat grain/gluten during harvesting and processing is a real product-quality risk worth flagging for anyone with celiac disease -- choose products specifically tested gluten-free.
How well does it work? / Evidence
? Emerging / limited evidence
Who should avoid it?
Avoid with: Celiac disease
Already taking it? Human efficacy evidence is essentially absent -- the supporting data are in-vitro antioxidant and cell-culture studies, not clinical trials. Reasonable, low-risk to continue as a nutrient-dense food-like product, but don't expect a proven therapeutic effect.
