L-Arginine 1000 Nutrex 120 capsules
Nutrex
L-Arginine 1000 is pure L-arginine in capsule form — 1000 mg per capsule. Arginine is a conditionally essential amino acid and a precursor for nitric oxide (NO) in the body.
Why exactly for NO production
Nitric oxide is a molecule that dilates blood vessels. Wider vessels = more blood to the muscles during training = better pump, more nutrients and oxygen.
Realistic about Arginine
There's a nuance here. Standalone L-arginine is not absorbed as well as L-citrulline (which converts to arginine in the kidneys). But citrulline is significantly more expensive. Arginine works, you just need a higher dose — 3-6 g before training.
Additional benefits
- Support for cardiovascular function in adults
- Immune support
- Aids in endogenous creatine production
- Supports erectile function (proven effect at higher doses)
When it doesn't work
In young and healthy individuals with good NO production — the effect on the pump is marginal. Where it truly helps — in men over 35-40 years old, whose natural NO production has decreased.
