ISO Protein contains triple cold filtered (TCF) protein. The TCF process ensures that the protein retains more of its amino acid profile by eliminating exposure to high temperatures. With traditional extraction methods, the quality of the amino acids may decrease due to heat and harsh conditions, which is not an issue with this supplement.

The ISO Protein Powder includes a complete protein profile, with 18 different amino acids, including:

  • Aspartic Acid
  • Leucine (BCAA)
  • Arginine
  • Isoleucine (BCAA)
  • Lysine
  • Valine (BCAA)

You get all three of the branched-chain amino acids (BCAA), all essential amino acids, and a selection of other beneficial amino acids. Here is a closer look at some of the most important compounds.

Aspartic Acid (2588 mg)

Aspartic acid is a nonessential amino acid, but it is incredibly beneficial for muscle development. It may increase your stamina and the production of testosterone, helping to support the growth of lean muscle mass. Higher levels of aspartic acid may also enhance your immune system and protect against toxins.

Leucine (2662 mg)

Leucine is a BCAA, which means that you need it to grow and repair muscle. In fact, it is widely considered the most important amino acid for building lean muscle mass. It helps trigger the pathway responsible for protein synthesis. As with most amino acids, leucine also assists with regulating blood sugar and energy levels.

Arginine (683 mg)

Arginine is an amino acid that changes into nitric oxide (NO). Increasing your NO levels helps blood vessels relax, which allows more nutrients and oxygen to reach your muscles during a workout. It enhances your performance, allowing you to push yourself a little harder. Arginine also stimulates the production of growth hormones, which are also essential for lean muscle gains.

Isoleucine (1413 mg)

Isoleucine is one of the three BCAAs. It is an important compound for promoting muscle growth and repair. It is found naturally in muscle tissues and helps regulate blood sugar, which helps ensure that your muscles receive enough energy during a workout.

Lysine (2336 mg)
Lysine helps your body produce various hormones and enzymes necessary for building and maintaining muscle. It also strengthens your immune system and promotes the production of collagen, which is required for strengthening everything from bones to tendons and ligaments.

Valine (1439 mg)
Valine is another BCAA, making it a required amino acid for optimal muscle development. It also helps keep your energy levels up and decreases fatigue. Valine has a stimulant effect that may help you maintain mental and physical stamina.

    More bang for your buck

    Always like a 5 pound size so I'm really glad one is available now! This isolate is amazing and has been a staple of mine since my friend suggested it to me. There is no reason to try or buy another brand - every flavor is better than the next. Just got the new Cookies & Cream flavor and WOAH this stuff is next-level! HIGHLY recommend.
