2.5/5 Weak evidence

Pump / nitric oxide evidence brief

Inositol-stabilized arginine silicate

This branded nitric-oxide precursor has early vasodilation and cognition studies, but direct gym-performance evidence is too narrow for recommendation.

Pump/cognition signals, limited outcomes focus / strength / endurance 5 linked sources Content audit 2026-05-04

Headline Finding

PK/PD and cognition RCTs show early signals; direct gym-performance evidence remains narrow and branded-product specific.

Dose Context

Trials commonly use acute 1.5 g class doses; product forms and co-ingredients can change interpretation.

Important Caveat

Meaningful performance, pump, or training outcomes need independent studies beyond biomarkers and small cognitive tests.

How To Read This Rating

The score reflects evidence that the supplement does its stated job. Some jobs are direct, such as strength, endurance, or recovery; others are indirect, such as sleep, mood, appetite, or health support. A real effect can still receive a cautious practical rating when dose, safety, product quality, or audience fit remain uncertain.
