Metabolic Whey is a delicious, creamy, 100% whey protein formula. Our unique protein blend Nat-Pro Optimizer is bioengineered to increase muscle size, strength and promote lean body mass. Nat-Pro Optimizer delivers an optimal source of whey protein. It is produced by a state-of-the art, low temperature, ultra-filtration process, which yields an extremely clean, high quality whey protein. This unique processing yields a High Biological Value protein, rich in branched chain amino acids and glutamic acid for advanced recovery, therefore, providing increased nitrogen retention without causing indigestion, stomach cramps or pains.

In addition, NAT-PRO Optimizer is fortified with cross flow, ultrafiltered Whey Protein Isolate, L-Glutamine and Digest-All AP. The biochemists at MRM have taken the "High Protein Diet" to the next level, without the worry of wasting ingested protein. The addition of Digest-All AP helps break down long and short chain peptides into smaller, more readily absorbable amino acids for maximum absorption and utilization. The problem with the "high protein" diet used by many athletes is that the body is unable to naturally digest and absorb high amounts of protein at one time. Digest-All AP helps the body release more amino acids from ingested protein than the action of digestive enzymes alone. When an athlete takes Metabolic Whey, enhanced with Digest-All AP, the body can absorb more amino acids directly into the muscle tissue, which helps to increase muscle size, strength and lean body mass.

Protein needs vary from person to person. Heavy resistance exercise and physical activity stimulates muscle hypertrophy (growth) as well as protein metabolism. Through stimulating myofibrillar protein synthesis (resistance training) and mitochondrial protein synthesis (endurance training), significant quantities of amino acids are oxidized during each type of exercise. Recent data concerning the protein needs for athletes and exercise enthusiasts has found that dietary protein intake of 1.2-1.8 g/kg body weight per day is likely needed for individuals participating in regular strength or endurance exercise to achieve optimal muscle growth. New information has increased that to even 2.4 g/kg for intense training athletes.

To increase muscle size and strength, it is crucial that you consume enough high quality protein to put your body into a state of positive nitrogen balance. Each scoop of Metabolic Whey provides 22 g of a unique protein blend of non-denatured and easily digested whey protein. It Only has 2.5 g of Carbohydrates per serving with Zero Added Sugars (fructose nor sucrose). The carbohydrates in Metabolic Whey are naturally occurring from the whey protein as well as the flavors.

This formula was designed to provide your muscles with all of the essential amino acids required for maximum nitrogen retention necessary for muscle strength, growth and development. Metabolic Whey is a delicious protein supplement and is Aspartame-Free!

Sucralose addition Disappointing

Posted by VictorySecret on Mar 03, 2008

Bought product because it processed at low temperatures and contain enzymes. But sucralose addition made me very disappointed given all the bad press it has gotten. I will lobby the firm to take this artificial sweetner out. I am very particular about what goes into my body.

I was disapointed to see that it had sucralose and artificial flavors. When I bought the smaller size it had Stevia instead and No artificial flavors so I assumed the ingredients would be the same. It tastes ok and mixes well though.

Great Product.

Posted by Reviewer1107737 on Feb 13, 2010

I constantly watch my weight and diet. This product allows me to not only control those areas very well but, this product is also great for controlling my diabeties. It doesn't spike my levels, keeps me from craving and fullfills my protein needs well.
