Blood Sugar

Blood Sugar Evidence Ranking

Within this category, verdicts with higher evidence scores appear first. Verdicts without a score stay lower in the same list.

• B 68 Berberine x Blood glucose, cholesterol, and lipids
  Evidence for improvement in blood glucose and lipid surrogate markers is repeated, but it is not evidence for prevention of clinical events, and co... · View verdict →
• B 66 Cinnamon (cinnamon; mainly cassia cinnamon/Ceylon cinnamon and cinnamon extract) x blood glucose
  Fasting glucose repeatedly shows a small decrease in short-term RCTs and meta-analyses, but HbA1c, diabetes prevention, and long-term clinical outc... · View verdict →
• C 58 Okra extract (Abelmoschus esculentus) x Improvement in postprandial glucose and HbA1c
  Repeated positive signals exist for glycemic surrogates, but regional concentration, formulation heterogeneity, and low certainty yield C with 58 p... · View verdict →
• C 58 D-allulose (D-psicose) x Attenuation of postprandial glucose rise
  The acute postprandial signal has moderate certainty, but long-term HbA1c and fasting-glucose benefits are absent, resulting in C with 58 points. · View verdict →
• C 55 Resistant maltodextrin (resistant maltodextrin/resistant dextrin) x Postprandial blood glucose, bowel movements, and triglycerides
  Postprandial blood glucose and triglycerides are numerical markers, so under the methodology rules it is difficult to go above C. · View verdict →
• C 55 Mulberry leaf extract (DNJ/1-deoxynojirimycin) x Postprandial blood glucose
  There is a signal of reduced postprandial glucose pIAUC in Lown 2017, but the maximum grade is C because it is a surrogate marker, and there is a c... · View verdict →
• C 55 Touchi extract (fermented soybean extract) x Suppression of postprandial blood glucose elevation
  Randomized human trials exist, but they are small and heavily concentrated within one commercial research program. · View verdict →
• C 50 L-arabinose x Attenuation of sucrose digestion and absorption and postprandial glucose control
  An acute co-ingestion effect exists for sucrose drinks, but mixed-meal and CGM findings are null and long-term evidence is absent, resulting in C w... · View verdict →
• C 49 Black seed oil (Nigella sativa) x Combined improvement of blood glucose, blood pressure, and lipids
  Signals of improvement in surrogate markers are repeated across three metabolic domains, but formulation and population heterogeneity and the absen... · View verdict →
• C 48 Evening primrose seed extract (PGG) x Attenuation of postprandial blood-glucose rise
  A human trial means the evidence is not unknown, but a single manufacturer product and postprandial surrogate outcome limit it to C with 48 points. · View verdict →
• C 47 Apple cider vinegar x Improvement of postprandial glucose, HbA1c, and body weight
  Glycemic surrogate-marker signals are highly heterogeneous, the vinegar study has an ingredient-attribution limit, and the large-effect weight pape... · View verdict →
• C 46 Chromium (mainly chromium picolinate) x blood-glucose management and dieting/weight loss
  Glycemic markers show some improvement signals but weak consistency and clinical meaning, and dieting effects are limited to low-certainty signals... · View verdict →
• C 44 Nopal/prickly pear cactus (Opuntia, prickly pear, nopal) x Blood glucose, weight loss, and cholesterol
  There are human signals, but most are small, acute, and surrogate-marker studies, so the grade is C. · View verdict →
• C 44 Gymnema sylvestre leaf extract x Reduction of blood glucose and sugar cravings
  Design and heterogeneity limitations in glycemic studies and short, conflicting craving trials result in C with 43 points. · View verdict →
• C 43 Resistant starch x Improvement of insulin sensitivity and fasting glucose
  There are many RCTs, but pooled findings conflict and all outcomes are surrogate markers, resulting in C with 48 points. · View verdict →
• C 42 Moringa (Moringa oleifera) x Nutrition, blood glucose, antioxidant, and cholesterol
  The nutrient content is close to factual, but efficacy for blood glucose, antioxidant effects, and cholesterol is at the small-study and surrogate-... · View verdict →
• C 40 Salacia reticulata/oblonga extract x Suppression of the postprandial glucose rise
  An acute postprandial surrogate signal exists, but the species mismatch and negative long-term FPG and HbA1c place the judgment at the lower end of... · View verdict →
• C 40 Vanadyl sulfate x Improvement in insulin sensitivity and blood glucose
  Very small short-term before-and-after surrogate signals and the absence of rigorous controlled trials result in C with 41 points. · View verdict →
• C score not listed Banaba leaf extract (corosolic acid) x postprandial blood-glucose improvement
  The evidence is conflicting or limited. · View verdict →
• D score not listed Bitter melon / Jerusalem artichoke (inulin) x blood-glucose control
  Human evidence is insufficient or was not confirmed in key trials. · View verdict →
