The Claim

Acute ingestion of HMB is associated with upregulation of TNFα signaling genes (e.g., TNFRSF1A, CCL2, CXCL2) in human skeletal muscle, despite concurrent suppression of muscle protein breakdown.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
44score
Challenges
0score

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

How it works
1 study reviewed
In plain English

Taking HMB shortly before exercise is linked to increased activity of certain inflammation-related genes in muscle tissue, even though the breakdown of muscle proteins decreases at the same time.

See the scientific wording

Acute HMB ingestion is associated with upregulation of TNFα signaling genes (e.g., TNFRSF1A, CCL2, CXCL2) in human skeletal muscle, despite concurrent suppression of muscle protein breakdown, suggesting a dissociation between inflammatory gene expression and physiological catabolism.

What the research says

1 study

  1. Study: The Influence of Acute Beta-Hydroxy Beta-Methylbutyrate (HMB) Ingestion on the Human Skeletal Muscle Transcriptome

    HMB, a supplement made from a protein building block, turns on some inflammation-related genes in muscles, but at the same time, it stops muscles from breaking down — so even though the body signals inflammation, it’s actually protecting the muscle.
