Marketing Claims Vs. Reality
HMB 1,000 mg per serving.
The panel prints HMB 1,000 mg per two capsules, as calcium beta-hydroxy beta-methylbutyrate monohydrate.
Strength and recovery.
HMB reduced markers of muscle damage and raised strength in untrained people starting to lift (Nissen 1996; Rowlands 2009). In trained lifters the pooled effect was trivial (Rowlands 2009; Sanchez-Martinez 2018).
Independent lab results available.
The label prints the lookup address. We did not retrieve a report for a specific lot, so we can confirm the statement, not a result.
What Our Test Actually Found
The directions are the product
Every bottle on this list contains the same compound. What separates them is whether the label gets you to 3 g a day. NutraBio prints 1 g three times daily with meals; two others print a third or half of that.
No fillers at all
Most capsules need a flow agent. This one lists the capsule shell and stops, which is rare and is why it scores 10 on formula.
What HMB can and cannot do
HMB is a breakdown product of leucine. In people new to training it produced small strength gains; in trained lifters two meta-analyses found no meaningful effect on strength or fat-free mass (Sanchez-Martinez 2018; Jakubowski 2020). Buy it with that in mind.
Full analysis: all pros & cons (8), buy if / skip if
- Label gives 3 g a day in three doses
- Vegetable capsule with no excipients
- Lookup for independent lab results printed on the label
- Form stated on the panel
- Six capsules a day
- A bottle lasts 20 days at 3 g
- $1.10 a day, mid-range
- Not NSF Certified for Sport
- You want the label to give you the studied dose and timing
- You want a vegetarian capsule with no excipients
- You want lab results you can look up
- You already train regularly and eat enough protein: meta-analyses found no meaningful effect in that group
- Cost per day comes first: BulkSupplements powder is $0.28 a day
- You do not want to take six capsules a day
Three 1 g doses a day is what the studies used, and this is the only label on the list that says so. The capsule is vegetarian with no fillers, and the bottle points to independent lab results. It is not the cheapest: a bottle covers 20 days. Keep expectations modest, because the pooled trials found little or no effect of HMB in trained lifters.
NutraBio's bottle tells you to do what the researchers did. The directions read: take one serving, two capsules, three times daily with meals. That is 3 g a day in 1 g doses, the schedule the ISSN position stand describes (Wilson 2013). The panel lists HMB 1,000 mg per serving 'as calcium beta-hydroxy beta-methylbutyrate monohydrate', and under other ingredients it names the vegetable capsule (hypromellose, water) and nothing more. The label also prints 'CheckMySupps.com: view independent lab results' and a GMP and FDA-inspected facility mark. At six capsules a day the 120-capsule bottle lasts 20 days; at $21.99 on Amazon US on Oct 11, 2026 that is $1.10 a day.
The HMB whose label matches the studies
If you want to try HMB as it was tested, this bottle saves you the arithmetic: two capsules with each of three meals. The capsule is as clean as they come. It costs about a dollar a day, and the honest expectation is a small benefit if you are new to training or returning from a layoff, and little if you already lift regularly.

Quick Answers
How much NutraBio HMB should I take?
The label says one serving of two capsules three times daily with meals, which is 3 g a day. That matches the dose in the ISSN position stand (Wilson 2013).
Does HMB build muscle?
In people new to resistance training it produced small gains in strength (Rowlands 2009). In trained lifters, meta-analyses found no significant effect on strength or fat-free mass (Sanchez-Martinez 2018; Jakubowski 2020).

The ISSN position stand concludes that about 38 mg of HMB per kg of body weight a day, taken close to training and for two weeks before a hard bout, can reduce muscle damage and aid recovery; that calcium HMB and HMB free acid have both been used, with too little research to call one superior; and that long-term use is safe.
