This is a letter written by the SVP of marketing with Visalus. It is a good explanation of what the shakes are all about.

All About The Vi Shakes

When Dr. Witherly and I created the shake, we wanted to create the perfect 'meal' to help people build and maintain lean muscle, burn fat, and feel healthier.

The Tri-Sorb protein blend is a unique blend of highly absorbable proteins. First we use non-GMO soy that has been processed to remove isoflavones that can impact estrogen. Why soy? It is a complete protein, easil...y digested, and adequate consumption can help the body reduce cholesterol and c-reactive protein. Studies show that soy can build lean muscle as good, and in some studies better than whey proteins.



We then use a whey concentrate, and the newest technology in whey hydrolysate. This is the most concentrated and 'clean' protein on the market today, and is very expensive. The key reason is it builds lean muscle. The FDA allows it to be called a 'fat loss accelerant' as a result..the only protein that can use that claim. Our proteins have been specially processed to remove fat, lactose, and carbs.



We add in the Aminogen, a patented and clinically tested amino acid to aide protein absorption. Many body builders buy this product in nutrition stores to aid their body. We include it.



The key is that not all proteins are created equal. If you read the nutritional labels, some will use gelatin to 'spike' the grams of protein. Gelatin is great for skin and hair, but not so good at building muscle. Some use milk powder or milk protein. Great for bone health, but not so good at building lean muscle. Some use whey, which is ok, but only about 75-80% absorbed. So with ours, it's quality, not quantity...and we absorb more because of our blend.

Our shake is not just for weight management. It is for nutrition, and for health. The shake when mixed with non-fat milk or soy milk delivers 20-25 grams of protein, which is the amount nutritionists recommend we get in each meal.



Now body builders claim they often need more, because they are trying to build lean muscle. This may not be true, as not all proteins are created equal. This is the key reason we don’t put ‘grams’ of protein on our shake and tout it like many store brands do. I say this because some brands pump up the ‘grams’ of protein by adding gelatin (great for skin/hair/nails, but not lean muscle). Some use dehydrated milk powder, some just whey. Those also are ok, but not the latest in science.



We use a combination of proteins because they act differently in the body. The soy is used because of it’s heart health benefits Adequate consumption of soy in the diet can help the body lower c-reactive proteins, an indicator of inflammation and possibly heart disease. Soy is also easily digestible, and a complete protein. Our soy is unique in that we use a non-GMO Soy (not genetically modified), and was specially processed to remove the isoflavones that can impact estrogen. While those isoflavones may be beneficial, we know that women with fibroids, muscle builders, and others worry about the impact of estrogen. Non-GMO soy is about 45% more expensive than regular soy, but we chose to use it because of the concerns some people have about soy.



We use a whey concentrate for fast acting hunger control. Then we use a unique whey hydrolysate, which is the latest technology and is very expensive. It helps retain lean muscle, and is very highly absorbed. While some wheys can be absorbed about 80%, whey hydrolysate is much higher. It is a pure, clean, and concentrated protein. Combine that with the Aminogen, and we have more ingredients to help build, and maintain lean muscle while promoting fast loss.



So the 3 types of proteins help support heart health, bone health, muscle health, digestive health, and can help curb hunger quickly, and last too!



For athletes, it is recommended that they get protein into their body within 30 minutes after completing a workout. Protein will help the muscles repair themselves, and quicker. This is why our shake was designed to mix in water, and still taste great, and why we have it in individual serving packets. People can take the packet to the gym, and mix it in water and get it into their bodies quickly. The key points of difference are the quality of the proteins that we use (absorbability) as well as the fact that we added Aminogen®. Aminogen is a patented, and clinically tested ingredient that has been shown to help the body better utilize the protein. This way, you get more nutrition into the body and the muscle. We are also lower sodium than most brands (I’ve not found one yet lower than us).



Here is some information I found, that may be useful:



A few bodybuilding and weight training coaches recommend protein intakes of 40 percent of energy; for example 40% protein, 40% carbohydrate; 20% fat. Let's take a look at this. In the 4000 calorie diet of our 100 kilogram bodybuilder, 40% protein would be 1600 calories, equivalent to 400 grams of protein at 4 calories per gram. That's 4 grams/protein/kilogram body weight/day; over four times the RDI and twice what's scientifically defensible. Not good.



Fast and Slow Proteins



How quickly amino acids get transported to blood and how quickly they then get assimilated into muscle and other tissue for repair and rebuilding is the basis of this idea. According to some enthusiasts, fast proteins such as whey are superior to slow proteins like casein. Both are derivatives of milk products. Here are some values (Bilsborough 2006):



•Egg protein 1.3 grams/hour



•Casein isolate - 6.1 grams/hour



•Whey isolate - 8-10 grams/hour



There's not much evidence that these variations make a difference to muscle building over the longer term, although whey has shown some advantage in short-term studies.



Yet the other useful information that can be gleaned from the numbers above is that with average protein absorption of, say, 7 grams/hour, a theoretical absorption is limited to around 168 grams each day (24x7). If accurate, it makes the 400 gram/day protein diets look entirely unnecessary at best.



Very high-protein diets may not be safe over time for the following reasons:



•High levels of nitrogen and amino acids can be toxic.



•High-protein diets are not safe for those people suffering from chronic kidney disease. Up to 20 percent of the population may be undiagnosed.

Protein and Strength Athletes



While endurance athletes are easy to convince of the need for a high carbohydrate, low fat diet, strength athletes are a bit harder to convince of the need for adequate carbs and moderate protein. Strength athletes have long adhered to high protein diets in order to build muscle. This idea of high protein = more muscle is a bit overstated.



According to the research of sports nutritionists, strength athletes require high carbohydrate and adequate glycogen stored in the muscle. They point out that all high intensity; powerful muscle contractions (such as weight lifting) are fueled with carbohydrate. Neither fat nor protein can be oxidized rapidly enough to meet the demands of high-intensity exercise. Adequate dietary carbohydrate must be consumed on a daily basis to restore glycogen levels.



In fact, research shows that high protein/high fat diets can hurt performance. An inadequate amount of carbohydrate in the diet can result in:



•Reduced muscle glycogen stores in the muscle and liver •Decreased endurance •Decreased maximal effort •Decreased serum glucose levels •Increased risk of hypoglycemia



High protein/high fat diets can also have a negative overall impact on health, including the following:



•Increased risk of certain cancers



•Increased calcium excretion and increased risk of osteoporosis •Reduced intake of vitamins, minerals, fiber and phytochemicals



But Don't Strength Athletes Need More Protein To Build Muscle?



Research hasn't shown this. In fact most strength athletes get far more protein than is necessary to promote muscle synthesis. The current protein recommendations for optimal muscle building in a strength athlete are 1.6 - 1.7 gm protein per kg of body weight. For a athlete weighing 90 kg (200 pounds) that is a total of 145 - 154 grams of protein a day [about 3 small chicken breasts]. There is no scientific evidence that more than 2.0 grams of protein per kg of body weight has any additional benefit in muscle strength or size
