It not only offers all of the essential amino acids your body needs each day to sustain and repair itself, but also has other health and fitness benefits as shown in scientific studies[*].

Most notably, research suggests whey protein may boost fat-burning, decrease cravings, speed metabolism, and support healthy fasting insulin and lipid levels[*][*][*][*].

All of those benefits mean that whey protein supplements can offer significant advantages for people looking to lose weight and stay healthy.

In this guide, you’ll learn all about the best whey protein brands, including nutrition facts, ingredients, benefits and drawbacks, and reviews from customers.

What are the 3 Types of Whey Protein?

The three types of whey protein powder are whey protein concentrate, whey protein isolate, and whey protein hydrolysate (also called hydrolyzed whey protein)[*].

While all three types of whey protein come from milk (usually cow’s milk), they’re processed differently from one another, resulting in different properties[*].

Whey concentrate is the least processed or refined form of whey protein and it has more leftover lactose (milk sugar) and milk fat remaining[*]. 

As a result, it’s got less protein per serving (usually around 21 grams of protein per 28 gram serving). However, whey concentrate is usually the most economical whey protein because the manufacturing process is less costly.

Whey isolate is whey protein with as much lactose and milk fat removed as possible. This form of whey protein has more protein per serving (typically 25 grams of protein per 28 gram serving), but also tends to cost more than whey concentrate.

Finally, whey protein hydrolysate or hydrolyzed whey is the most processed form of whey protein[*]. It’s also the most expensive, because the extra processing costs more money for manufacturers.

The manufacturing process of hydrolyzed whey breaks protein molecules down into smaller molecules called dipeptides and tripeptides that are made up of fewer amino acids[*].

Whey hydrolysate may absorb slightly faster than other forms of whey, but that doesn’t necessarily make it better[*]. 

Most studies comparing whey protein hydrolysate to other forms find that it offers similar benefits without any measurable advantages[*][*].
