Black Mulberry, Goji and Black Bean Tea

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.

• Mulberries · Randomized controlled trial, 24 participants · 2017
  Post-prandial self-monitored glucose was lower than placebo (18.2%), but A1C did not differ between mulberry leaf extract and placebo. Serum creatinine rose about 15% in the extract group.Limitation: Small pilot: only 17 of 24 enrolled participants completed the study, limiting statistical power.PubMed 28619294 · 3 more mulberries studies
• 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
• 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
