The Claim

Combined supplementation with creatine monohydrate (3 g/day) and β-hydroxy-β-methylbutyrate (HMB, 3 g/day) for 6 weeks, together with physical conditioning, significantly improves functional strength outcomes (leg/back strength, arm flexion strength, upper-body endurance, and core endurance) in physically active older adults aged 60–82 years, and these improvements occur largely independently of changes in skeletal muscle mass.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

Taking creatine and HMB supplements for six weeks while doing physical training increases functional strength in active older adults. This strength gain happens without needing to increase muscle size.

See the scientific wording

Combined creatine monohydrate (3 g/day) and β-hydroxy-β-methylbutyrate (HMB, 3 g/day) supplementation for 6 weeks, alongside integral physical conditioning, significantly improves functional strength outcomes—including leg/back strength, arm flexion strength, upper-body endurance, and core endurance—in physically active older adults aged 60–82 years, and these improvements are largely independent of changes in skeletal muscle mass.

Why this might work

Creatine and HMB help muscles make energy faster and reduce protein breakdown. When combined with exercise, these supplements improve how the brain talks to muscles, increasing the number of muscle fibers activated and making movements more efficient. This leads to greater strength and endurance without needing bigger muscles.

  1. Study: Combined creatine and HMB co-supplementation improves functional strength independent of muscle mass in physically active older adults: a randomized crossover trial

    The study shows that taking both creatine and HMB while exercising for 6 weeks helps older adults get significantly stronger and have more endurance, even though they didn't gain much muscle size—just like the claim says.
