Citrulline malate already supplies citrulline, so adding L-citrulline can create duplicate high dosing and GI effects.
Every entry follows the same shape: what is happening, the mechanism, and the recommendation.
What is happening. Citrulline malate already supplies citrulline, so adding L-citrulline can create duplicate high dosing and GI effects.
Mechanism. Duplicate citrulline raises arginine and nitric oxide pathways.
Recommendation. Count total citrulline from all products and reduce doses if stacking.
