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.

• Goji berries · Meta-analysis, 161 participants · 2012
  Compared with placebo (n=80), the goji juice group (n=81) reported greater improvements in several self-rated symptoms, including stress, mental acuity, sleep quality and overall well-being, under a random effects model.Limitation: Outcomes were self-reported symptom questionnaires, and several symptoms showed significant heterogeneity across the four pooled trials of a single branded juice.PubMed 22897500 · 3 more goji berries studies
• 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
• Ginger · Meta-analysis, 23 studies · 2022
  Overall, acute and delayed nausea and vomiting did not differ significantly between ginger and control groups. A subgroup taking 1 g/day or less for over four days had less acute vomiting (OR 0.30).Limitation: Clinical heterogeneity between trials required subgroup analyses, and the authors state that sufficiently large, high-quality RCTs are still needed.PubMed 36501010 · 3 more ginger studies
