About This Product
NOW Sports Arginine & Citrulline Powder is an amino acid supplement designed to provide L-Arginine and L-Citrulline. It received an N+ Score of 32 and a grade of F, placing it in the 'poor' tier. The product lists 2 total ingredients with 100% label transparency, providing 1.5g of L-Arginine and 1.5g of L-Citrulline per serving. However, research suggests that both L-Arginine and L-Citrulline are underdosed at these amounts when aiming for commonly studied clinical benefits, which typically require higher dosages. This product might be considered by those looking for a foundational amino acid supplement, but its low N+ Score indicates that the dosages provided may not be sufficient for significant physiological effects.
