There are three main types of whey protein sold as supplements.
Whey Protein Isolate (WPI, Whey Protein Isolate)
Whey Protein Concentrate (WPC, Whey Protein Concentrate, Whey Protein Concentrate)
Whey Protein Hydrolysate (WPH, Whey Protein Hydrolysate, Whey Protein Hydrolysate)
The big difference between WPI and WPC is the protein content.
At the raw material level, more than 90% of WPI and more than 80% of WPC are proteins. Both are called "anhydride conversion values", and the content rate is in a state without water, so the content rate as an actual object, which is also called "genutsu", is slightly lower.
When it comes to commercialization, each company adds seasoning, dissolution and foaming control, and other ingredients to this raw material, so the content rate will drop a little more.
Considering only the amount of protein, even protein using WPC can be said to be the same as WPI if you take a little more than 10%.
However, the higher protein content means less other ingredients, mainly fats and carbohydrates.
Like protein, both fat and carbohydrates have calories, and fat in particular has more than twice the calories of protein for the same amount of grams. is recommended.
WPI is also recommended for trainees who want to cut carbs and cut their bodies.
A few grams of carbohydrates may not be a problem for "ordinary" people who are not so strict, but people who are strictly doing things like "up to 50g of carbohydrates per day" cut carbohydrates even a little. I want to, so a few grams may make a big difference.
