The Claim
L-citrulline supplementation does not produce a statistically significant change in lean mass gain in individuals undergoing resistance training.
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 L-citrulline supplements does not lead to an increase in muscle mass in people who do resistance training.
See the scientific wording
L-citrulline supplementation has no significant effect on lean mass gain in individuals undergoing resistance training.
Taking L-citrulline does not increase the rate at which muscle cells build new proteins or activate cells that help muscles grow bigger, so muscles do not get larger from resistance training when L-citrulline is added.
What the research says
1 studyThis study found that taking citrulline pills along with working out didn't help people gain more muscle than just working out alone. So, citrulline doesn't seem to boost muscle growth.
