One of the most promising nutritional supplements for the preservation of muscle mass in old age is beta-hydroxy-beta-methylbutyrate (HMB), for preserving lean body mass in muscle wasting conditions.It is said that Daily HMB supplementation (typically up to 3 g/day) is demonstrated to have an anti-catabolic effect, enhance protein synthesis, attenuate proteolysis, increase muscle mass, and decrease muscle damage in older adults.This seems like a good source of HMB.

Great product

These capsules are white and standard-sized. They have no odor or taste to me. I found them easy to swallow. If you follow the bottle's instructions and take 2 per day, then this is a 90 day supply. At the current price of 21.59, that makes it about 24 cents a serving, which is very reasonable in my opinion.I do see on the bottle that this product contains sesame, if by chance you have a food allergy to sesame. It also contains some fillers in this supplement, which I wish they didn't do. But outside of that, I think it is a good supplement and company. I am happy with how I feel taking this product and I have no stomach upset.

I normally take HMB and D3 separately but decided to try this supplement that mixes the two and I'm not sure how I feel about it yet. I think I've had better results the separate way, but this is an easy one for someone who wants to combine the two.I use the HMB and D3 to aid in protein intake and haven't been great results lately. I can't put the blame on this stuff, but trying to neck what has been different lately and this was one of the variables.

I'm a senior, so staying within my budget is the major factor for purchases. This supplement keeps me in the main stream of health and not in the doctors' office for bad news.
