Is Nutricost HMB 1,000 mg underdosed?
Verdict
1 g a dayas the label directs · studies use 38 mg/kg/day of HMB
Below research doseTaken as the label directs (1 serving a day, 1 g each), it gives 1 g a day; studies use 38 mg/kg/day (2.85 g at 75 kg). Studies dose it by bodyweight; this uses 75 kg. HMB builds up in the body through daily use over weeks; a lower daily amount still builds up, just more slowly.
One capsule gives 500 mg, so reaching the low end of what studies use (2.85 g) takes 5.7 capsules a day; it ranks 8th of 10 HMB supplements here by dose.
To reach the research dose. It would take 6 capsules a day (3 g) to reach the 2.85 g at 75 kg studies use, more than the label's directions, which allow 2 capsules a day (1 serving a day).
