Overview

Optimum Nutrition Gold Standard Plant Protein provides 24g of protein from a blend of organic pea protein, organic brown rice protein, and sacha inchi protein — creating a complete amino acid profile that rivals whey. The Gold Standard brand brings mainstream credibility to plant protein, with the same quality standards that made Gold Standard Whey the world's best-selling protein. Each serving includes 4g BCAAs (naturally occurring) and only 1g of sugar. The Vanilla and Chocolate flavors are surprisingly good for plant protein.
