The Claim
Vitamin D modulates leptin secretion from adipose tissue and suppresses myostatin expression in skeletal muscle, thereby enhancing energy sensing and removing a key brake on muscle growth.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking vitamin D might help your body release a hormone that tells you when you're full and also stop a protein that blocks muscle growth, so you could feel more energized and build muscle more easily.
See the scientific wording
Vitamin D modulates leptin secretion from adipose tissue and suppresses myostatin expression in skeletal muscle, thereby enhancing energy sensing and removing a key brake on muscle growth.
What the research says
1 studyStudy: Retinoic acid and vitamin D(3) powerfully inhibit in vitro leptin secretion by human adipose tissue.
This study found that vitamin D reduces leptin (a fat hormone) in fat tissue in a lab dish, which matches part of the claim. But it didn’t look at muscles or myostatin, so we can’t say if vitamin D helps build muscle like the claim says.
