Suggested/Recommended/Usage/Directions

Use MET-Rx Protein Plus any time of the day including: Immediately After Exercise: Makes an excellent post-workout shake by providing fast digesting proteins for immediate muscle support plus slow digesting proteins for extended amino acid delivery and recovery.* With Meals: Drink along with your meal to increase the overall protein quality and content. You can also mix into oatmeal or add to recipes such as pancake and waffle mixes. In Between Meals: Keeps levels of amino acids elevated so your body doesn’t go into a catabolic state that may otherwise lead to muscle loss.* Before Bed: The high content of slow-digesting proteins in MET-Rx Protein Plus makes it a perfect before-bed supplement as it provides “time-released” amino acid delivery to your body. Use in conjunction with an intense daily exercise program and a balanced diet including an adequate caloric intake.

The Secret is in the Protein Source!

Formula re: Contains

The renowned MET-Rx protein formulation consists of METAMYOSYN, which combines premium whey protein isolates and casein proteins, plus L-Glutamine and naturally occurring Branched Chain Amino Acids from protein — Isoleucine, Leucine and Valine.

General Statements: All Other Content

Whey is a fast-acting protein while casein is slow-acting, which results in a more prolonged absorption rate to extend the delivery of amino acids to muscles.* Milk protein is a natural source of whey and casein.
