The Claim
In middle-aged and older adults with type 2 diabetes, improvements in microvascular endothelial function (LnRHI) following citrulline supplementation are correlated with improvements in relative calf muscle strength (CMSrel).
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.
In middle-aged and older adults with type 2 diabetes, when microvascular endothelial function improves after taking citrulline, relative calf muscle strength also improves.
See the scientific wording
In middle-aged and older adults with type 2 diabetes, the improvement in microvascular endothelial function (LnRHI) following citrulline supplementation is correlated with the improvement in relative calf muscle strength (CMSrel), suggesting a potential mechanistic link between vascular perfusion and muscle function in this population.
Citrulline is converted into arginine, which fuels the production of nitric oxide in blood vessel walls. Nitric oxide relaxes the small blood vessels in muscles, allowing more blood, oxygen, and nutrients to flow through. This improved blood flow boosts the muscle's ability to generate force, leading to stronger calf muscles.
What the research says
1 studyIn older adults with type 2 diabetes, taking citrulline improved both blood flow in small vessels and leg strength, and those who saw better blood flow also tended to get stronger legs — suggesting the two are connected.
