What is Soy Protein Isolate 90?

Soy Protein Isolate 90 is a 90% protein derived from soybeans. Containing over 27.5g of protein per 30g serving, this supplement has a fantastic amino acid profile, which is particularly high in glutamine and arginine. Of all the non-dairy protein sources soy protein's amino acid profile is most closely matched to that of whey. It's ideal for people who can't consume dairy protein.

How does Soy Protein Isolate 90 work?

Soy is naturally high in protein and contains more protein than many meats, eggs and fish, as well as containing a number of essential micronutrients, such as calcium, iron and potassium. This supplement is manufactured using the highest quality GMO-free soybeans to yield a 90% protein which is extremely low in fat and carbohydrate. It is instantised with a small amount of soy lecithin to ensure easy mixing and a smooth consistent protein shake. As a non-dairy protein source it is ideal for vegetarians, vegans and those with dairy intolerances.

How will Soy Protein Isolate 90 benefit my training?

Being high in both essential and nonessential amino acids, soy protein isolate can increase protein synthesis, recovery and lean muscle growth with one recent study showing a protein blend containing whey, casein and soy to be more effective than whey alone. Soy protein’s high arginine content will increase vasodilation and improve recovery through increased blood flow, and may increase nitric oxide (NO) levels.

How should I use Soy Protein Isolate 90?

It is important to consume a minimum of 1g of protein per pound of body weight daily to support lean muscle growth and recovery. As a general rule we recommend 3-5 servings daily to help you achieve this target. This supplement can be taken at anytime of day to increase your protein intake. We recommend one serving immediately post workout, and in between meals as required. Each serving will provide you with 27.5g of protein.

Will this affect my testosterone levels?

No, don't worry, that's a myth! It was believed for many years, particularly in the bodybuilding community, that soy protein could decrease testosterone levels and increase estrogen levels. Recent studies refute this myth, showing that soy does not appear to significantly affect levels of either hormone. Some recent studies have shown soy protein to be as effective as whey protein at promoting lean muscle growth.
