Wheatgrass

Tier 3 — weak evidence · Antioxidant · Detox claims · Nutrition

A popular juice bar ingredient marketed as a superfood with dramatic health claims. While it contains chlorophyll, vitamins, and minerals, no clinical trial has demonstrated unique health benefits beyond what you would get from eating any green vegetable. One small trial in ulcerative colitis showed modest benefit, but the study was not replicated. Claims about detoxification and cancer prevention are not supported by evidence.

Dose: 3–5 g/day powder or 30 mL fresh juice; no unique health benefit demonstrated beyond general nutrition
