    Soy Protein Isolate

    Anyone else taking Honeyville Soy Protein Isolate? A 4lb bag has 24g of protein per oz. Has anyone had personal experience with Soy Protein Isolate?

    I can tell you that soy is def not optimal due to the amino acid profile. Whey is far better
    Anything said by exerciseordie is for educational purposes only! PERIOD!!!! Don't do illegal shit.

    Not True

    Soy is higher in...

    1) Glutamine

    2) Branch Chain Amino Acids (Leucine/Isoluecine/Valine

    3) Argenine

    Why not take the money you would spend on soy and buy some real food. Like beef. It has a superior amino acid profile and ZINC which you may be deficient in. Good luck.

    I plan on eating both, but was interested supplementing a small portion (about 1/4 to 1/3) of my daily protein needs. Soy protein seems to be the least expensive and very affordable. It would be 1,555 grams of protein for $24.

    I'm surprised that no one else has any experience with using soy protein...

    Misconception

    Like you, I've heard this forever and never used it.

    However, the research indicates that isn't true.

    Whey vs. Soy -- You've Been Tricked
    http://www.timinvermont.com/fitness/soyvswhy.htm

    "Animal research suggests some great advantages of using soy protein isolate as a bodybuilding supplement. Research has shown that the isoflavone daidzein found in soy-protein isolate might have a gender specific normalizing effect on sex-hormone production. Lab animals experienced testosterone and growth hormone excretion as well as muscle growth in males, while the female animals experienced a decrease in these hormones and fat loss."

    Soy Vs. Whey

    "The latest studies into soy protein suggest it does not decrease testosterone and raise estrogen, as previously thought."

    "... the American College of Sports Medicine (ACSM) Meeting, May 2004, and sponsored by the US National Dairy Council, found the post-workout consumption of isonitrogenous and isoenergetic soy drink to be statistically significant in hastening mass, fat-bone free mass (FBFM) and increases in strength..."

    Soy's Amino Acid Profile

    1) Soy is higher in Arginine than Whey.

    2) Soy is higher in Glutamine than Whey

    "Arginine is well known as a stimulant of anabolic hormones that stimulate muscle formation, while glutamine is considered essential during metabolic stress."http://www.bodybuilding.com/fun/drobson71.htm

    Synergistic Protein Stack

    Synergistic: The sum is greater than the individual parts.

    Synergistic Example: 2 + 2 = 5

    What research shows is that combining two proteins with different amino acid profiles, magnifies the effetiveness.

    "Used together in an exercise regimen, soy and whey proteins complement each other well. Whey protein, as mentioned, is high in branched chain amino acids, used as an important energy source by the body during exercise, while soy protein has high amounts of the amino acids arginine and glutamine."

    Another Look

    The best thing to do is review the information posted above, do your own research and come to you own conclusions.

    As for me, Soy Isolate appears to have some definite strength. Even better is the low cost of it.

    Soy protein is cheap because its awful. Its also not a particularly good choice for males. Its a phyto-estrogen. Just do some research. Beef, chicken, fish, and eggs are great and supplement with whey or a whey egg protein blend. All of those give more bang for the buck than soy and taste better.

    Everything I've read places soy protein on the bottom end of protein choices. There are several better sources as many listed above.

    That's a great tip. Youtheory makes a collagen protein powder that would have saved me mixing collagen into my shakes separately. Neocell collagen 1&3 was $9 alone.
