Clean Stim Free Pre Workout Nitric Oxide Booster

Clean Stim Free Pre Workout Nitric Oxide Booster

Type Zero Health

#Pre-Workout

Safety75
Efficacy65
Transparency80
Based on Examine, Wikipedia, and 23 other sources

Overview

This stim-free pre-workout aims to boost nitric oxide production and enhance exercise performance. It contains L-Citrulline, Arginine AKG, and Beet Root Extract to support vasodilation. While some components are well-dosed and backed by research, other ingredients such as Beta-Alanine and Apple Cider Vinegar Powder are included at levels that may not provide significant benefits, and the combination of these ingredients has minimal research to support the claimed benefits.

The Good

Contains L-Citrulline at a clinically effective dosage (6g), supporting nitric oxide production and potentially enhancing blood flow and exercise performance.

Betaine Anhydrous is included at a clinically effective dosage (1.5g) for supporting power output and muscle endurance.

Beet Root Extract provides nitrates, which may enhance nitric oxide production and improve exercise performance.

The Bad

Beta-alanine is underdosed, potentially failing to deliver its ergogenic benefits fully.

Apple cider vinegar powder is underdosed, limiting its potential benefits on blood glucose control.

GABA is included at a dosage where bioavailability and efficacy are questionable.

Is it for you?

Best For: Athletes, fitness enthusiasts, individuals sensitive to stimulants, those seeking muscle pumps and improved blood flow.

Skip If: You have pre-existing medical conditions, are pregnant or nursing, or are taking medications that interact with nitric oxide boosters.
