HMB supplements

HMB works through daily use over weeks, so what matters is how much you take in a day. For each product we take the label's own directions (how much per serving, how many servings a day) and compare the daily amount with what studies use: 38 mg/kg/day. Products that reach that range when taken as directed come first, then by the least their directions give a day (counted only up to the top of the range); commission never changes the order.

10 products. Where the directions give a range, the verdict judges the most they give in a day. Read the HMB guide for the studies behind the dose. "Proof" is a published independent lab test, a certifier listing we read on the certifier's own site (usually for listed lots only), or "Label claim only" when we found neither.
