What is the best type of protein powder? Do I have to supplement protein?
You do not have to take a protein supplement. As long as your daily protein intake is met, there is no need to take protein via a supplement powder.
If you are going to supplement with a protein powder, whey protein is considered the “gold standard” for high quality protein or the best type of protein powder. If you are looking for a plant based protein, soy protein powders are of very high quality also.
However, if you do not enjoy the taste of your protein, the best type of protein powder is one you enjoy.
See Protein Quality for a detailed answer with sources.
