Citrulline

Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

Some human supplement-context evidence is present and directly informs the score.

Key Evidence #1
Public scholarly dataCitation signal: 211
review

The impact of supplementing this important urea cycle intermediate on cardiovascular and metabolic health outcomes is examined and future directions for investigating its therapeutic impact on cardiometabolic health are identified.

Key Evidence #2
Public scholarly dataCitation signal: 121
observational

This review aimed to investigate whether oral administration of the amino acids l-arginine and l-citrulline, which are potential substrates for eNOS, could effectively reduce BP by increasing NO production, and suggests that oral Arg supplementation can lower

Key Evidence #3
Public scholarly dataCitation signal: 116
observational

Oral L-citrulline supplementation reduced the time take to complete a cycle ergometer exercise trial and significantly improved subjective feelings of muscle fatigue and concentration immediately after exercise.

review

This review provides a comprehensive approach to different studies of the endogenous synthesis of CIT, metabolism, pharmacokinetics, and pharmacodynamics as well as its ergogenic effect in exercise performance.

Public scholarly dataCitation signal: 66
observational

L-citrulline supplementation rescued NO levels better than L-arginine supplementation by inhibiting ROS production and arginase 2 protein expression, which rescued HG-induced endothelial senescence.

Public scholarly dataCitation signal: 60
observational

The available data support the hypothesis that L-arginine or L-citrulline supplementation would be suitable for implementation in resource-constrained settings and will enhance placental vascular development and improve birth outcomes, and the evidence for the
