MET Rx is an American brand that pioneered the concept of meal replacements in the field of nutritional supplements. After its introduction on the market in the mid-1990s, MET Rx became very popular with bodybuilders and athletes, who used it to increase their protein intake and enhance their training results.

Meal replacement powders, also known as MRPs, are easy-to-drink shakes that can be used to boost protein and nutrient intake in the diet. Although MET Rx continues to be popular with athletes, it is also an important dietary supplement for many senior citizens.

Because it is easy to consume and contains a high amount of protein, elderly people use MET Rx meal replacement in their diets so they can reach the right proportions of macronutrients they need to stay healthy.

Nowadays, the MET Rx brand produces a wide assortment of high-performance whey protein powders, drinks, and supplements that come in many different flavors.

However, the MET Rx original meal replacement shakes are still offered in just their two original flavors, extreme chocolate and vanilla. The shakes contain a balanced mix of vitamins and minerals as well as protein and a high level of calcium.
