The Claim
High-dose vitamin D supplementation reduces myostatin expression per unit of muscle mass, which diminishes autocrine inhibition of muscle hypertrophy and thereby enables greater anabolic capacity.
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 a lot of vitamin D might help your muscles grow bigger by turning down a natural brake that stops them from growing.
See the scientific wording
High-dose vitamin D reduces myostatin expression per unit of muscle mass, thereby diminishing autocrine inhibition of muscle hypertrophy and enabling greater anabolic capacity.
What the research says
1 studyThe study found that taking a high dose of vitamin D while working out lowered a protein called myostatin, which normally stops muscles from growing — so vitamin D may help muscles grow better by turning down this 'brake'.
