MRM's Natural Gainer is an ideal health supplement for individuals looking to add useful calories to their diets as well as to increase or maintain lean body mass. All Natural Gainer makes it simple to add extra calories, in proper proportions, to a delicious beverage without the hassle of preparing another to-go meal. It was designed for all age groups and active lifestyles.

MRM's unique protein complex provides all the essential amino acids to enhance lean muscle growth. Natural Protein Optimizer™ is a special combination of ultra-filtered, low temperature processed, whey protein concentrate, cross flow microfiltered whey protein isolate, micellar casein, and enzymes to provide with both immediate and sustained release of amino acids. Natural Protein Optimizer™ provides optimal amounts of essential amino acids that growing muscles crave, especially BCAA's, Glutamine, and Arginine. MRM emphasizes the amount of protein per serving since it is the most prominent macronutrient proven to increase lean muscle mass.

Additionally, MRM has added trehalose, a slow release energy substrate that renders little to no effect on insulin with maximum effect on energy and minimal fat storage. All Natural Gainer contains a unique carbohydrate complex consisting of VitaFiber™ (isomalto-oligosaccharide), glucose polymers (maltodextrin) and "low glycemic index" fructose. This preferable combination of fast, slow, and indigestible carbohydrates provides and excellent source of fiber and calories that are less prone to increase "body fat" while offering a long-lasting source of energy and satiety.
