Buying Guide

Choose the right arginine form

Arginine appears as raw L-arginine, AAKG (arginine alpha-ketoglutarate), or combined with citrulline; AAKG and citrulline blends can boost nitric oxide production more efficiently than low-dose L-arginine alone

Check per‑serving dose and serving size

Look for clear milligram or gram dosing per serving and the number of servings per container to judge daily intake and cost‑effectiveness

Prefer transparent ingredient lists

Choose products that list exact amounts of active ingredients rather than proprietary blends so you can match research-backed doses for recovery

Consider format and mixability

Powders offer flexible dosing and fast absorption for pre/post workouts while tablets are convenient for on-the-go use

Match supplements to your recovery goals

If your priority is circulation and endurance, seek nitric-oxide–focused blends; for joint or cardiovascular support, look for combinations with citrulline or supporting nutrients
