Power 90 Extreme, or P90X, is a home exercise program produced by BeachBody Fitness that includes a restrictive diet plan. With varying proportions of carbohydrates and protein accompanying the plan's three phases, proper nutrition is vital to meeting your fitness goals while on P90X. As such, BeachBody recommends using the P90X Peak Recovery Formula as a post-workout dietary supplement.
Flavorings, Protein and Texture
The main ingredients in the Peak Recovery Formula are fructose, whey protein concentrate, dextrose, maltodextrin, natural and artificial flavors, citric acid and carrageenan gum. Dextrose and fructose, both natural sugars, add sweetness and simple carbs to the drink. Further flavor is added by the starch maltodextrin, natural and artificial flavors and citric acid, which also serves as a preservative. The majority of the drink's protein comes from whey protein concentrate which, along with maltodextrin and carrageenan gum, helps to provide the Peak Recovery Formula with a thick, frothy texture.
Aside from lecithin, all of the lesser ingredients in the Peak Recovery Formula are vitamins, minerals, amino acids and other workout supplements. In order, the remaining ingredients are: d-alpha tocopheryl acetate, l-arginine, ascorbic acid, creatine monohydrate, l-glutamine, lecithin, magnesium oxide, sodium chloride, potassium phosphate, beta carotene, niacinamide, pyridoxine HCL, riboflavin, thiamine mononitrate and cyanocobalamin. While the egg-derived lecithin contributes to the drink's protein content, it mainly serves to help the drink blend in water.
Of the drink's vitamin supplements, d-alpha tocopheryl acetate is a source of vitamin E, ascorbic acid provides you with vitamin C, beta carotene provides vitamin A, niacinamide provides vitamin B3, pyridoxine HCL is a source of vitamin B6, riboflavin provides you with vitamin B2, thiamine mononitrate provides vitamin B1 and cyanocobalamin is a source of vitamin B12. The drink's mineral supplements are magnesium oxide, sodium chloride and potassium phosphate. The Peak Recovery Formula also contains two amino acid supplements, l-arginine and l-glutamine, and creatine monohydrate, a workout supplement that might help to build muscle mass and burn fat.
Blending two scoops, or 60 g, of the Peak Recovery Formula in 12 fl. oz. of water provides you with 220 calories, 10 g of protein and only 2 g of fat. Based on a 2,000 calorie per day diet, this drink provides you with 13 percent of your daily carbs, or 39 g, less than 1 g of fiber and 10 percent of your daily cholesterol. Due to its numerous supplements, the Peak Recovery Formula contains 30 percent of your daily intake of vitamins B1, B2, B3, B6 and B12, 60 percent of your vitamin A, 500 percent of your vitamin E and 750 percent of your vitamin C.
