HMB supplement may be useful for below categories of people
- For beginners
- Older people
- Competitive Bodybuilders switching routines for anti-catabolic effect
- People with diseases that cause muscle loss
HMB is marketed as an anti-catabolic agent (purposed to reduce the rate of muscle breakdown) rather than an anabolic agent (purposed to increase muscle mass). HMB, currently, appears to be a pretty interesting supplement for the purpose of reducing muscle wasting during periods where muscle atrophy is accelerated (cachexia, AIDS, bedrest) and should theoretically work in athletes on a calorie restricted diet but is not fully established for this role yet (which is a notable issue, since glutamine has a large dichotomy between clinical and healthy populations).
For general population having a healthy diet rich in protein, this supplement would not be necessary.
