RTD 51 shakes are protein supplements that are designed for the fitness minded individual who needs additional, high performance protein as a part of the total workout program. The shakes all pack 240 calories per serving, so they are hardly the type of supplement that those interested specifically in weight loss might choose. However, dieters who are already in the thick of a serious strength training program might appreciate a protein supplement to feed lean muscle mass after workouts. We will take a closer look at the RTD 51 protein shakes to see what benefits they might provide.

The RTD 51 protein shakes are available for purchase on the company website; MET-Rx. They can also be found through a host of online retailers, with some offering discounted pricing. The shakes also come in a wide variety of flavors, including berry blast, peanut butter, cookies and cream, creamy vanilla, frosty chocolate and mocha blast. All of the shakes are low in fat and contain the high performance metamyosyn protein. Unfortunately, we could not find any offers of free samples that allow customers to try the product before they buy. Since some protein supplements are notorious for an unsavory flavor, it seems that a free sampling would be helpful for consumers trying to choose such a product.

List of Ingredients

The ingredients in the RTD 51 shakes include Water, METAMYOSYN® VPR Protein Blend (Calcium Caseinate, Milk Protein Concentrate, Whey Protein Concentrate), Natural Flavors, Cellulose Gel, Vitamin and Mineral Blend (Dipotassium Phosphate, Tricalcium Phosphate, Sodium Phosphate, Sodium Ascorbate, Sodium Citrate, dl-Alpha Tocopheryl Acetate, Niacinamide, Vitamin A Palmitate, d-Calcium Pantothenate, Ferrous Sulfate, Manganese Sulfate, holecalciferol, Zinc Oxide, Pyridoxine Hydrochloride, Thiamin Hydrochloride, Riboflavin, Copper Sulfate, Folic Acid, Biotin, Chromium Chloride, Sodium Molybdate, Potassium Iodide, Sodium Selenite, Phylloquinone, Cyanocobalamin), Sucralose, Cellulose Gum, Sodium Hydroxide, Acesulfame Potassium, Carrageenan, FD&C Red #3.

The whey protein mix in this formula is commonly used by bodybuilders, but is not necessarily an effective weight loss ingredient. We also do not see any proven fat burners or appetite suppressants in this mix, giving us further doubt about the usefulness of this product in a weight loss program.

Product Features

The shakes are sold on the MET-Rx website and cost $43.08 for 12 15-ounce cans at the time of this review. If you consume one shake per day, as most bodybuilders probably will, the cost will be fairly high for this product. In addition, we could not find free samples or a money back guarantee listed on the company website, making the RTD 51 shakes a costly venture indeed.

    I see that RTD 51 has 30g of cholesterol. How healthy (or not) is that for someone that has a high cholesterol on medication?
