Whey Concentrate  

This is the most common type of whey protein. Whey concentrate has a little more carbs and fats than whey isolate. Most whey concentrate has a protein content of 70% or higher. 

Whey Isolate

Isolate is the highest quality form of whey protein. It’s also considered to be the highest-quality protein on the market. It will contain little fat and carbs, and be at least 90% protein. 

Calcium Caseinate

This is a very common form of casein protein, and it’s slow digesting.

Micellar Casein

This is the highest quality form of casein protein available. The primary advantage of micellar casein is that it will stay in your system for 7 hours. That makes it ideal for nighttime use, or at the start of a long day at work. 

Milk Protein Isolate

This is a high-quality protein containing both milk and whey protein. It will be slower digesting than regular whey protein.

Egg Albumen

Also known as Egg White. This is a very high-quality protein with medium digestion speed. 

Glutamine Peptides

This is the peptide-bonded form of glutamine. This makes it more stable so it can be easily mixed in a protein complex such as the BSN Syntha 6 Protein Matrix.
