Why do I need a protein supplement?
Everyone should have all 20 amino acids available to the body through the bloodstream all of the time. If the body does not have adequate amounts, it will break down muscle and other tissues to get the amino acids it needs for vital, life-sustaining functions − this is known as a catabolic state. Protein is the best way to get all of the essential amino acids that the body needs. However, it can be difficult for some people to get high-quality protein daily through whole foods alone. Supplementing can thus be a good option for these. Even if you are able to get the sufficient amount of protein through your diet, protein-rich foods take time to digest and may be moderately high in calories. If you are counting calories and require fast-digesting protein, you should consider a protein supplement.
