How do I choose an L-citrulline product — and what does the right format look like?

Shelf order follows the trial evidence and the form logic together: NOW's pure L-citrulline powder leads as the trial-dose format (the mild-ED trial's form and dose — our ED page's shared product), the bulk malate carries the training literature's format, and the arginine-citrulline dual closes as the entry-level combined route. All three feed the same NO pathway; the form, the dose, and the physician conversation (for the medicated) are the decisions. The products below are educational examples — not medical recommendations.
