A key callout of Complete Protein is that it contains more essential amino acids per gram than whey! Not forgetting that Huel Complete Protein is so much more than just protein, it also contains essential fats, a source of fibre and all 26 essential vitamins and minerals. With sustainability, it’s pretty clear cut between animal & plant based. Plant-based protein sources come out on top, for example, even a more expensive animal-based protein that is organic or grass-fed will use more land and water than an intensively produced plant-based protein.
