You can read more about whey protein types, however this post is going to focus solely on whey protein concentrate, and its benefits and side effects.
As mentioned in the above post, whey protein concentrate is the cheapest form of whey protein, and is the easiest for companies to mass produce. It is by far the most common type of whey protein when looking to purchase any powder, however because it is cheap does not necessarily mean that it isn’t good. Althouth the lowest type of protein by weight, concentrate is still exceptionally high in protein as it is, well, a protein concentrate.
Whey protein concentrate can be found as low as 30% protein by weight, up to 90% by weight. That means you need to be aware of the type of whey protein concentrate you are selecting. Less concentrated formulas are often cheaper and filled with filler ingredients, such as sugar, artificial flavor, and even fat and cholesterol. That is because the whey has not been processed to a high enough degree to remove the byproducts present in whey.
Ideally even if choosing the lower form of whey (Concentrate that is) as a supplement, you need to ensure you are still selecting a higher quality product. Cheap-ing out on a product you might use daily is a sure way to end up using an improper supplement that harms your weight loss and fitness goals more than it helps them.
