Protein Soy Supplement

What makes soy better than some other protein sources out there, including even whey protein in some respects?

First, Soy protein is a "complete" protein. Complete simply means that soybeans contain all the essential amino acids for human health -- and they must be supplied by the diet because they cannot be produced by the human body.

While some other proteins are complete ones, many of them are not.

So, if you're an athlete, or just someone looking to live a healthy lifestyle, a protein soy supplement probably has a place in your diet, as long as you're not allergic to soy based products.

Rather than us do all the talking, we will reprint a guest article here called:

Soy Reduces Harmful Free Radical Formation During Exercise Better than Whey Protein.

By Dr. Aaron Tabor, MD

Evidence from recent clinical trials suggests that soy may have added exercise benefits compared to other protein sources, in particular whey protein (a popular protein among many athletes). Researchers from Ohio State University have just completed a study examining the effect of soy protein on muscle weight gain and “antioxidant status”.(1) A higher antioxidant status means that your body is able to better neutralize free radicals. Free radicals produced during exercise are harmful to muscle and other tissues.

Sidenote from Nutritional Supplement Info: This is a fact that many athletes don't know...that the more you exercise the more free radicals you create! That's one great reason to add a protein soy supplement to your diet.

In the study, men taking part in a weight training class were given protein bars containing either soy protein or whey protein (33 grams/day) for 9 weeks. The men consuming soy protein maintained a healthy antioxidant status, while the antioxidant status of men consuming whey protein actually worsened. By reducing free radical production during exercise, soy protein may help lessen muscle damage and fatigue. Both protein sources increased muscle mass of the men.

Another recent study tested the effects of soy protein and whey protein on “lipid peroxides” (higher levels are considered worse), in men performing moderate intensity, weight resistance exercise.(2) This study also compared soy to whey protein (men consumed 40 grams/day for 4 weeks prior to each exercise session). Lipid peroxide levels were reduced in the soy protein group as early as 5 minutes after the exercise session, while peroxide levels were not reduced until 24 hours after exercise in the whey protein group.

In summary, these new studies demonstrate that soy protein can help build muscle mass similar to more commonly used protein sources. However, soy protein provides the added benefit of reducing oxidative stress through the antioxidants naturally present in soy (isoflavones and saponins). Numerous studies indicate that soy isoflavones may be responsible for soy’s antioxidant properties.(3) Isoflavones are not found in whey protein or other common protein sources.
