8.3 Our Score

3-in-1 Nitric Oxide Support System Advanced 3-in-1 nitric oxide support combining L-Arginine, L-Citrulline & Beetroot in one truly vegan capsule. Why juggle three separate bottles? Designed as a multi-pathway system: each ingredient supports nitric oxide pathways differently, working together for a more complete approach than single-ingredient supplements. A clean choice for those seeking an all-in-one nitric oxide blend with arginine, citrulline, and beet root powder.
590 mg L-Arginine + 266 mg L-Citrulline per Serving — 956 mg Active Ingredients Each 2-capsule serving delivers 590 mg of L-Arginine and 266 mg of L-Citrulline, plus beetroot — for 956 mg of combined active ingredients per daily dose. L-Citrulline acts as a precursor to L-Arginine, supporting nitric oxide production. No proprietary blends, no hidden numbers, no marketing math. Source of antioxidants that help protect cells against the oxidative effects of free radicals.
With Beetroot for Natural Nitrate Support Includes beetroot (Beta vulgaris, root) — a natural source of dietary nitrates that supports nitric oxide pathways alongside L-Arginine and L-Citrulline. Beetroot's traditional role in circulation and antioxidant support makes it a natural complement to amino-acid–based nitric oxide formulas — completing the multi-pathway approach for a balanced 3-in-1 nitric oxide blend with beet root powder.
Stimulant-Free Daily Use & Pre-Workout Formula Take two capsules once a day — before training, before a long day, or as a daily nitric oxide routine. No caffeine, no beta-alanine tingle, no stimulants of any kind. Easy-to-swallow vegan capsules instead of messy pre-workout powders or caffeinated drink mixes. A clean choice for active men and women seeking consistent nitric oxide support without the crash or jitters of stimulant-based formulas.
Truly Vegan 90-Day Supply Made in Canada NPN 80138824 180 truly vegan hypromellose capsules per bottle — never gelatin, never animal-derived. A full 3-month supply manufactured in a Canadian Health Canada–licensed, GMP-certified facility under NPN 80138824. Every batch is third-party lab tested for purity, potency, heavy metals (arsenic, cadmium, lead), and microbiological safety. Non-GMO, gluten-free, free from artificial fillers — a premium nitric oxide blend you can trust.
