Overview

The effectiveness of RexaVar is difficult to fully assess due to the reliance on proprietary blends where individual ingredient dosages are not disclosed. While some ingredients like L-Citrulline, L-Arginine, Maca, and Tongkat Ali have research supporting their roles in male sexual health and performance, their efficacy at the precise levels present in the 'Proprietary Protodexx Complex' or 'Protodexx Matrix Complex' is unverifiable. The inclusion of Niacin at 45mg (225% DV) is noted, but its direct contribution to the primary claims is limited beyond general metabolic support.

The Good

Includes ingredients (L-Arginine Nitrate, L-Citrulline) that support nitric oxide production for potential blood flow benefits.

Contains traditional herbs (Tribulus, Tongkat Ali, Maca) with some historical and limited clinical evidence for male vitality and libido.

Provides a high dose of Niacin, which supports general metabolic health.

The Bad

Relies heavily on undisclosed proprietary blends, making precise dosage and efficacy assessment impossible.

Strong warning label indicates potential risks for individuals with common medical conditions.

Specific claims like "72.1% increase" lack transparent scientific backing for the combined formula.
