THE SECRET IS THE SOURCE OF PROTEIN!

Research studies show that 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 naturally contains both whey and casein - to provide slow and fast-digesting properties.

Study finds subjects using MET-Rx OMR twice per day gained more muscle and strength over 12 weeks than a group receiving whey protein supplements.

Use MET-Rx(R) Meal Replacement 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(R) Meal Replacement makes it a perfect before-bed supplement as it provides "time-release" amino acid delivery to your body.
