Plant Protein

As its name suggests, plant protein is derived from plants. The lack of animal-based sources ensures that everything reviewed here is suitable for vegetarians and vegans. This section may include protein extracted from soy, pea, brown rice, hemp, quinoa, nuts, seeds, lentils, chickpeas and more. Unlike individual sources of plant protein, the products in this category are formulated to contain all nine essential amino acids – making them complete protein supplements. Plant-based protein powders are said to contain antioxidants that are not found in animal protein. Plant protein also comprises more fiber than animal products, which is thought to help improve digestive health.
