What is Whey Protein Powder?
Whey Protein Powder is one of the two proteins in milk (the other being casein). While normally the two milk proteins remain intermixed when you drink or cook with milk, whey can be isolated from casein during the cheesemaking process, when it is drained from cheese curds as the watery part of milk, usually a yellowish liquid.
Whey that is powdered commercially and sold as a high-protein dietary supplement called whey protein or whey protein powder. Whey protein powder is full of quality protein alpha-lactalbumin, protein building blocks like branched-chain amino acids (notably leucine and cysteine), and other essential amino acids. Whey protein is popular among bodybuilders and athletes, who use whey (often mixed into smoothies or other drinks) to maximize their daily protein intake.
Whey Protein Powder is used mostly in food products and is the least concentrated form of whey with lots of lactose.
There are three types of whey protein supplements:
- Concentrate: Whey protein concentrate ranges between 30 to 75 percent protein and contains more lactose, fat, and nutrients.
- Isolate: Whey protein isolate is usually around 90 percent protein and contains less lactose, less fat, fewer carbs, and fewer nutrients.
- Hydrolysate: Whey protein hydrolysate is a “pre-digested” protein, meaning it has gone through part of the hydrolysis process and will be much faster absorbed than whey concentrate or whey isolate. It ranges in protein percentage and contains almost no lactose, and its reduced allergen potential makes it popular for infant formula and for those with lactose intolerance.
*If pasteurized, it is the partial sterilization at a temperature and for a period of exposure that destroys objectionable organisms without major chemical alteration of the substance.
*Non-RBGH or rBGH/rBST Free means not grown hormone was used to increase milk production.

I Heart Keto Mart Rating Guide
I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly
