RECENT STUDIES SUPPORT SOY'S EFFICACY
The latest studies into soy protein suggest it does not decrease testosterone and raise estrogen, as previously thought.

The first of these studies, presented at 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, when compared to other post-workout formulations (skim milk and maltodextrin beverage), both of which had a similar degree of efficacy6.

This study demonstrated that intact proteins from both soy and milk protein are effective in supporting muscle hypertrophy, lending a degree of support to soy as a legitimate post-workout nutritional beverage.

This studies method involved randomizing 34-subjects to milk (n=12, skim milk), soy beverage (n=11) or maltodextrin beverage (n=11) (note: n= number of subjects per randomized group), using a double-blind allocation process.

Participants trained 5 days-per-week on a whole body split resistance training program and consumed 500ml of their assigned drink immediately and 1h post-exercise following every training bout.

The most recent study into soy as an effective aid to muscle-building (this study served to help dispel the notion that testosterone decreases in concert with soy consumption), was presented on April 5 2005, and underwritten by the Solae Company.

They found daily supplementation of soy protein, whey or a soy/whey blend resulted in an increase in lean body mass and did not negatively affect testosterone or estradiol levels in 41 male athletes engaging in a weight-training program (9).

The study's purpose was to compare the effect of supplementation of 50-grams-per-day of four different protein supplements in combination with resistance training on lean body composition and serum s*x hormone changes in males.

The method of this study involved, over a 12-week-period, the 41-subjects consuming protein shakes twice daily and participating in three hypertrophy-oriented sessions per-week.

The protein shakes consisted of either soy protein concentrate (SPC), soy protein isolate (SPI), a soy/whey blend composed of a 50/50 mixture of SPI with whey protein concentrate (WPC) and whey protein isolate (WPI), or whey protein composed of a 50/50 mixture of WPC and WPI.

THE STUDY FOUND
All of the protein sources resulted in the desired affect of increasing lean body mass. In addition, there was no difference between the supplement sources on changes in testosterone levels.
The lean muscle mass gains that were demonstrated in this study are consistent with prior research looking at how soy and whey impact lean muscle mass in conjunction with an exercise regimen.
DISCUSSION
Athletes who incorporate both soy and whey protein in their nutritional regimens may benefit from their different rates of digestion and amino acid absorption. Whey protein digests more quickly, while soy protein digests more gradually.
Together, they may provide a more prolonged, deliberate release of amino acids to key muscle groups.
In addition, soy protein consumption may provide additional health benefits including a reduced risk of coronary heart disease when combined with a healthy diet. Recent studies also demonstrate that soy protein consumption may reduce the risk of certain kinds of cancer including prostate cancer.
This study is consistent with other studies, which have demonstrated that soy protein has unique benefits for exercising adults in improving antioxidant status. These findings indicate that soy protein can help combat free radical formation during exercise, which may help speed muscle recovery after exercise.
THE EXPERTS SPEAK
Greg Paul, Ph.D., director of health and nutrition for The Solae Company says:

"The results of this study show that soy protein is just as effective as whey protein in building lean muscle mass as part of a dedicated exercise and nutrition regimen, while contradicting the myth that soy protein may negatively impact testosterone levels in men.

"These results are consistent with prior studies which have compared the effect of whey protein and soy protein on lean muscle mass, and supports the notion that dedicated athletes may benefit from a nutrition regiment that includes both soy and whey proteins."

Douglas S. Kalman, M.S, R.D., Director of Nutrition & Applied Clinical Research at Miami Research Associates says:

"We believe that this study validates that soy protein is safe and just as effective as whey protein in helping exercising males achieve their fitness goals and supports the development of lean muscle mass."

BENEFITS OF SOY PROTEIN
A review of the research into soy consumption for health purposes, uncovered many benefits.

Soy protein has a 1.0 PDCAAS (Protein Digestibility Corrected Amino Acid score) score - the highest possible. The PDCAAS is the standard measurement of protein quality.
Soy protein increases the nutritional value of other foods due to its complete amino acid profile.
Soy has been shown to reduce the likelihood of heart disease through its ability to lower cholesterol1 12. Results from a meta-analysis of 38 clinical studies concluded that soy protein consumption may help lower total blood cholesterol and LDL-cholesterol as compared to animal protein consumption.
In 1999, the FDA determined that four-servings of soy protein per-day could reduce LDL cholesterol (the bad type, HDL being the good) by up to 10%.
Although soy helps to lower LDL, it doesn't effect HDL status, which is also a good thing. The American Heart Association also recommends the consumption of soy protein (with naturally occurring isoflavones) as part of a heart-healthy diet for those with elevated total and LDL cholesterol.
Soy protein is also thought to reduce the risk of other illnesses such as colon, breast and prostate cancer2 3 7, as well as osteoporosis. Research has shown several bioactive compounds found in soybeans (isoflavones being one) to reduce the risk of certain cancers7.
Soy enhances athletic performance6 8 9. The isoflavones found in soy protein produce antioxidant effects, which speed recovery and reduce muscle soreness and inflammation.
In addition, soy does supply a full complement of amino acids for the exercising muscles - muscles will become larger and stronger with soy protein. In fact, athletes who incorporate both soy and whey protein in their nutritional regimens may benefit from their different rates of digestion and amino acid absorption.
Whey protein digests more quickly, while soy protein digests more gradually. Together, they may provide a more prolonged, deliberate release of amino acids to key muscle groups.
Cost: one of the biggest benefits to the consumer is the considerable reduction in cost, using soy will present. With whey protein costs soaring, soy might prove to be much less expensive (around two-dollars-per-pound less).
Beneficial for women's health7. Consuming soy protein has a number of benefits unique to women's health, including the alleviation of symptoms associated with menopause, the protection of bone health and the a reduction of the risk of breast cancer.
CONCLUSION
Obviously, more research will need to be done, but if the studies presented here are anything to go by, the future of soy supplementation looks good.

This report is not intended to denounce whey protein or hail soy as the newest miracle product, but, rather, present another side to the whey vs. soy story, with the latest research to help people make more informed choices.

Soy protein could be an excellent anabolic aid, used independently, or in concert with whey protein, to stimulate further gains in muscle.

ISO PROTEIN uses Supro® brand soy protein, a high-quality complete protein derived from soybeans. Supro® is produced by The Solae Company. The Solae Company has been conducting soy protein research for more than 30 years.
Not only is soy protein a source of high-quality protein, it is thought to play both a preventative and therapeutic role in the following:
• Studies show naturally occurring isoflavones (such as those in Supro® brand soy protein) have increased the mineral content and density of bones, which may protect against the risk of bone fractures and osteoporosis.
• Studies have indicated that a regular intake of soy foods may help to prevent hormone-related cancers such as breast cancer, prostate cancer, and colon cancer.
• Soy works to lower LDL cholesterol (bad cholesterol) levels in the blood. Reductions in LDL cholesterol have been shown to help decrease the risk for heart disease.
• Soy may reduce triglyceride levels and increases HDL cholesterol levels (good cholesterol), which further reduces the risk of heart disease.
• Soy isoflavones, which are a natural phytoestrogen source, may help reduce menopausal symptoms such as hot flashes or night sweats.
• Soy is a complete protein, providing all of the essential amino acids.

Performance Nutrition
A broad range of scientific studies demonstrate that Supro® soy protein:
• Is a high-quality protein
• Supports the development of lean body mass
• Aids muscle recovery
• Provides energy for muscles during exercise
• Builds muscle strength in conjunction with an exercise program
• Reduces oxidative stress associated with exercise
• Maintains healthy hormone levels
• Sustains energy levels via its impact on glycemic index

Can Adding Soy To Your Protein Mix Lead To More Growth?
New research has found that adding soy to a casein and whey blend could help increase the length and total impact of your anabolic response to protein powder.
by Jim Stoppani, Ph.D.
Last updated: Jul 12, 2013
You've probably heard that you should drink whey protein after your workouts to boost muscle growth and increase protein synthesis. As it turns out, the best "whey" to go actually involves using a combination of fast- and slow-digesting post-workout proteins—typically whey (fast) plus casein(slow).
One type of protein you'll seldom hear mentioned in this conversation is soy, which is usually not associated with muscle growth and bodybuilding. Yet if you look more closely at the evidence, you'll find that adding soy to the mix won't detract from you gains—and it might even enhance them.

The Whey-Casein Combo ///

That's right, a growing body of research suggests that including both whey (fast-digesting) and casein (slow-digesting) proteins in your post-workout shake boosts and prolongs your body's anabolic response.
You can make a bigger impact on overall and long-term muscle protein synthesis by consuming whey and casein after a workout, compared to consuming whey protein alone. Research also shows that, over time, this combination leads to greater muscle growth.
Don't get me wrong, whey is still the protein king. It's the richest source of branched chain amino acids(BCAAs) and is the fastest-digesting protein you can throw down your gullet. That means it rushes its amino acids, including the critical BCAAs, to your muscle fibers to kickstart muscle protein synthesis.
But if you take whey by itself, that blip in muscle protein synthesis may be too quick to maximize muscle growth. By adding slower-digesting proteins to the mix, you keep muscle protein synthesis jacked up for longer. That means more muscle is built for a longer period of time.
Casein and Whey and Soy—Oh Boy! ///
While the whey-casein combo is a great post-workout choice, a brand-new study published in theJournal of Nutrition suggests that a combination of whey, casein, and soy proteins may be even better. While whey has a fast digestion rate and casein has a slow digestion rate, soy digests at a rate somewhere in between the two. From a timing standpoint, a casein-whey-soy blend theoretically could help your body sustain a higher level of protein synthesis for a longer period.
To test the theory, researchers from the University of Texas Medical Branch in Galveston had men consume 20 grams of whey protein or 20 grams of a whey-soy-casein combo one hour after a leg workout. Researchers found that both the whey protein and the mixed protein increased muscle protein synthesis to a similar degree. However, the mixed protein, with its differing rates of digestion, maintained a higher rate of protein synthesis for hours longer.
It could be argued that the same response would have been seen with a whey and casein combination. After all, other studies have shown the exact same result with only the dairy proteins. Keeping this in mind, my advice is to combine at least whey and casein to your post-workout shake. For best results, though, I recommend adding soy to the mix. I've been recommending a blend of whey, casein, and soy for almost a decade now.
The Soy Story ///
Because soy digests slower than whey, but faster than casein, it makes a nice bridge between the two and keeps a steady flow of aminos to your muscles. In addition to its speed of digestion, soy offers numerous other benefits that only improve the power of the dairy proteins to promote muscle growth. Many argue that soy protein does not promote muscle growth as well as the dairy proteins, as some studies have suggested. However, these studies either looked at a snapshot of the rate of muscle protein synthesis, or were conducted on animals.
The two studies that provided weight-training humans whey or soy over a long period showed similar results between the two proteins. One 2006 study from Canada, performed on untrained subjects, showed that weight training for six weeks while supplementing with an equivalent dose of whey or soy resulted in similar gains in muscle mass and strength.
And a 2007 study done by Douglas S. Kalman, Ph.D., R.D., found that trained male lifters who supplemented twice daily with either soy protein concentrate powder, soy protein isolate powder, a soy-whey protein powder blend, or a whey protein isolate all increased muscle mass to a similar degree during the 12-week training period.
Soy also has benefits that whey, casein, and other protein powders do not. First, soy has the ability to raise growth hormone (GH) levels. This appears to be due to its high arginine and lysine content. Research has also found that soy can boost nitric oxide (NO) levels. Virginia Polytechnic Institute and State University (Blacksburg) researchers found that the soy phytoestrogen, genistein, increased NO levels by increasing the amount of nitric oxide synthase (NOS), which is the enzyme that catalyzes the conversion of arginine into NO.
A 2004 Ohio State study comparing soy and whey protein bars on muscle growth reported that the men taking soy had better antioxidant protection following exercise. Another 2004 study, published in the International Journal of Sports Nutrition and Exercise Metabolism, found that trained men who consumed 40 grams of soy protein before lifting weights for four weeks had better antioxidant protection following a weight workout compared to men who consumed whey protein.
A 2005 study published in the Journal of Sports Medicine and Physical Fitness found that women consuming soy protein for four weeks had less oxidative muscle damage following exercise than those consuming only whey.
But, My Testosterone! ///
If you've been doing a little protein "research" on the Internet, you probably came across those dire soy protein warnings: Don't have soy or it will increase your estrogen levels and lower your testosterone. "Oh, no," you think, "I just had some soy milk and I can already feel my p***s shrinking!"

These fears have been perpetuated by a couple of old and poorly conducted studies. The most recent review study analyzed 15 quality studies done on soy and testosterone levels in men and concluded that soy does not alter testosterone concentrations in men.
I'm not suggesting that you take soy and soy alone. I'm suggesting that you add some to your whey-casein blend. Some of you might think it will be too expensive to buy three kinds of protein.
Honestly, I think it will save you money in the long run. Casein and whey protein powders have been getting more and more expensive. Soy, on the other hand, remains fairly inexpensive. By "cutting" your whey and casein with soy, you'll get more bang for your buck.

Soy’s Potent Amino Action
A decade of hard science has now confirmed a 180-degree turn for the reputation of the once-rejected soy protein, specifically soy protein isolate. Years of misinformation and poor interpretation of data yielded a disastrously wrong conclusion about soy protein. Now the scientific verdict is in: It’s an extremely valuable protein for bodybuilders and other athletes, and can actually enhance the potency of whey when the two are mixed together.
Studies confirm that soy protein is a complete protein, unlike other vegetable proteins. PDCAAS (the Protein Digestibility Corrected Amino Acid Score) is a measurement used by the world’s major health organizations to rate digestibility of protein and the protein’s ability to satisfy human amino-acid requirements. The highest possible PDCAAS score is 1.00. Isolated soy protein, casein, whey protein and egg white all have a PDCAAS score of 1.00.
Numerous studies prove that soy and whey are similar in their ability to promote lean body mass gain, but soy’s antioxidant power sets it apart during the recovery phase due to its potent effect in combating free-radical formation during intense training. This recovery-boosting effect is measured in what’s known as “critical cluster” aminos, which include naturally occurring glutamine, arginine and BCAAs. Soy protein isolate scores higher in amount of critical cluster aminos than whey, casein or egg.
Mix And Mass
There’s compelling evidence that adding casein to the soy-whey mix may be even better. At a recent conference, Blake Rasmussen, PhD, a professor who specializes in protein research at the University of Texas Medical Branch in Galveston, recently presented his clinical research study: “Effect of Protein Blend vs. Whey Protein Ingestion on Muscle Protein Synthesis Following Resistance Exercise.”
In this double-blind, randomized trial, 19 young, fit adult participants received ~ 20 g of the soy/dairy protein blend or whey alone one hour after a bout of high-intensity leg resistance exercise. However, they did not know which protein they were given. Each subject’s muscle protein fractional synthetic rate (otherwise known as mixed muscle protein synthesis, the processes underlying muscle building and repair) was measured multiple times over five hours. Muscle protein synthesis increased significantly in both the whey and protein-blend groups, yet remained significantly elevated three to five hours later only in the group receiving the soy/dairy protein blend. This means there was a prolonged delivery of amino acids to muscle tissue after consuming the beverage made with a soy/dairy blend compared to consuming a product made with whey alone. And, therefore, the processes underlying growth in muscle were extended for a longer period of time — a greater “anabolic window” — after resistance training.
The synergistic effects of 100% Soy Isolate when blended with whey alone or whey and casein make it a no-brainer to add soy to your protein regimen. Simply add a scoop of 100% Soy Isolate to your dairy protein and get ready for better results than you’ve ever had. Why would you want to miss out on that?
