Understand ketone supplements before you buy
Ketone Clarity is an independent U.S.-focused publication about BHB, exogenous ketones, supplement claims, and smarter product comparisons.
Editorial approach: We separate product marketing claims from evidence about ingredients and exogenous ketones. A biochemical effect is not automatically proof of meaningful long-term weight loss.
Leptozan ReviewProduct, ingredients, evidence, cost considerations, and limitations.
BHB SupplementsWhat beta-hydroxybutyrate supplements are and what research can—and cannot—tell us.
Exogenous KetonesHow ketone salts and related products affect blood ketone levels.
Leptozan AlternativesA framework for comparing ketone products without assuming one is best for everyone.
Start with the mechanism, not the promise
Exogenous ketone supplements can raise circulating beta-hydroxybutyrate (BHB). A 2023 systematic review and meta-analysis of 30 studies found an acute rise in blood BHB and a reduction in blood glucose after exogenous ketone supplementation. That evidence does not establish that Leptozan itself produces long-term weight loss.
