Wheat Grass
Also known as: Wheatgrass, Triticum aestivum, Wheat Grass Juice, WGJ, Wheat Grass Tablets
Effective Dosage
60-100 mL juice daily or tablet equivalent; No established standardized dose
What the Science Says
Wheat grass is the young green shoots of the common wheat plant, harvested before the grain forms. The most consistent clinical evidence comes from small studies in thalassemia patients, where daily wheat grass juice or tablets appeared to reduce blood transfusion requirements and modestly raise hemoglobin levels. One small randomized controlled trial found wheat grass juice significantly reduced disease activity in ulcerative colitis, and a pilot study suggested it may reduce chemotherapy-related blood toxicity in breast cancer patients. It also shows antioxidant activity in lab and small human studies.
What It Doesn't Do
Not proven to detox your body — that's marketing language with no clinical backing from these studies. No evidence it boosts energy, cures cancer, or reverses aging. The thalassemia results are promising but come from small, uncontrolled or poorly controlled studies — don't treat it as a replacement for medical care. No proof it helps healthy people with blood counts or immunity. Animal brain-protection results haven't been tested in humans.
Evidence-Based Benefits
Wheat grass is rich in vitamins, minerals, and antioxidants, which may contribute to improved overall health. Some studies suggest it may have potential benefits for reducing oxidative stress and supporting immune function.

Absorption & Bioavailability
Unknown — no pharmacokinetic studies were provided. Lab data shows it does not significantly inhibit CYP3A enzymes, suggesting low drug interaction risk via that pathway.
Red Flags to Watch For
- Most clinical trials are very small (16–69 patients) and lack rigorous controls — results may not hold up in larger studies
- Wheat grass is derived from wheat but is generally considered gluten-free at harvest; however, cross-reactivity testing shows it may trigger responses in allergen-sensitive individuals
- Worsening of nausea reported in some chemotherapy patients taking wheat grass juice — not universally well-tolerated
- No standardized dose or formulation exists across products — juice, tablets, and powder may have very different potencies
- Animal studies (cerebroprotection, antileukemic effects) have not been replicated in human clinical trials — do not extrapolate these findings to humans
