What studies say about the key ingredients

Traditional use is not the same as clinical proof. Here is the strongest human research we found for each ingredient, limitations included.

• Job's tears (coix) · Randomized controlled trial · 2024
  Myeloperoxidase activity rose significantly in the placebo group after 8 weeks but showed no significant change in the adlay tea group. Vascular endothelial function improved in the adlay group, especially in those over 40.Limitation: Participants were healthy adults and the outcomes were surrogate markers, so the results say little about clinical disease outcomes. Tea is a polyphenol-rich extract, not whole grain.PubMed 38945894 · 2 more job's tears (coix) studies
• Lotus seeds · Randomized crossover trial, 10 participants · 2019
  Lotus seed meals had a low glycemic index (GI 21–51 across the lotus seed and adzuki bean meals), while several other starchy foods did not differ significantly from rice. Lotus seed's in vitro hydrolysis index was also lower than that of other test foods.Limitation: Only ten healthy participants and acute single-meal tests, so findings may not apply to people with diabetes or to long-term intake.PubMed 30875961
• Black soybeans · Randomized controlled trial, 100 participants · 2013
  Systolic blood pressure fell more in the black soy peptide group (-9.69 mm Hg) than in the placebo group (-2.91 mm Hg) after baseline adjustment. Plasma malondialdehyde decreased and superoxide dismutase activity increased compared with placebo.Limitation: Used an isolated peptide supplement rather than whole black soybeans, and followed participants for only 8 weeks, so the results may not apply to food intake.PubMed 23924691
