Does Kefir Milk Have More Benefits Than Whey Protein?

Both kefir and whey protein offer ways to boost your nutritional intake while providing additional health benefits. You may wonder which of these dietary supplements has more to offer you. On the surface, both products provide ways to increase your protein intake. To determine which may be better, look beyond their nutritional content to see which is more appropriate for your body’s needs.

Kefir vs. Whey Protein

Kefir and whey protein are similar in that they can come from the same source, namely, cow’s milk. Kefir is a fermented cow's milk product, but it can also contain goat or sheep milk, too. Whey protein is one of two proteins found in cow’s milk, explains the Whey Protein Institute, that is isolated from milk during the cheese-making process. It is refined and dried to produce whey powder.

These micro-organisms support the immune system of the body, helping it fight off disease-causing bacteria and other pathogens.

In addition to these benefits, kefir is an excellent source of protein and other vital nutrients. A single one-cup serving provides 30 percent of the recommended daily allowance for calcium.

Benefits of Whey Protein

Whey protein is an easily digested form of protein that you can use to supplement your protein intake. Because it is a powder, you can add it to any smoothie recipe or liquid, boosting its nutritional value. Whey differs from some proteins in that it is a complete protein. A complete protein contains all of the essential amino acids, explains the Centers for Disease Control and Prevention. And amino acids are the building blocks for proteins that the body uses to repair tissue and build muscle mass.
