3. Pea Protein
This popular plant-based protein is easily digested and contains high levels of essential muscle-building compounds such as glutamine and branched-chain amino acids. One cup of peas contains nine grams of protein. Unlike many other plant protein sources, pea protein doesn’t contain anti-nutrient compounds that can inhibit the uptake of vitamins and minerals during digestion. Pea protein is also available in supplement form, and, while a common complaint of plant-based protein powders is related to their grassy and earthy taste and texture, pea protein powder is mild in both taste and texture.
