Promino Keeps Rejuvenate Prices Low Despite Whey Protein Surge

Promino Nutritional Sciences Inc, a company focused on muscle health and performance nutrition, has maintained the retail prices of its Rejuvenate product at $24.99 for 14 servings and $39.99 for 30 servings in the United States. This decision comes in the wake of a significant increase in the cost of whey protein, which has more than quintupled since 2023.

According to the press release, WPC80 whey protein concentrate, a common form of whey protein, has surged to approximately $14.50 per pound in 2026, compared to $2.49 per pound in the same period in 2023. This dramatic rise is attributed to growing protein demand and constrained production capacity.

Despite the soaring costs of whey protein, Promino has kept its retail pricing for Rejuvenate at a competitive level. The company claims that its product is priced as much as 40% lower per serving than a leading 2-pound whey protein benchmark. At the maintained retail prices, Rejuvenate costs approximately $1.79 per serving for the 14-count and $1.33 per serving for the 30-count.

Rejuvenate is a plant-based essential amino acid formulation designed to support muscle protein synthesis. The product is packaged in convenient individual stick packs and is available in flavors such as Raspberry Burst, Citrus Blast, Tropical Mango Pineapple, and Harvest Grape. It is currently available in approximately 6,800 CVS and 660 Kroger locations, among other U.S. retail channels.

Promino's approach to muscle nutrition is fundamentally different from that of conventional whey protein. The company argues that a small, low-calorie serving of targeted amino acids can provide a muscle protein synthesis response comparable to 20 grams of whey protein. Published human research by Bukhari et al. supports this claim, showing that a 3-gram leucine-rich essential amino acid formulation stimulated muscle protein synthesis equivalently to a 20-gram bolus of whey protein in older women at rest and following exercise.

The company believes that maintaining accessible retail pricing, broad U.S. availability, and a convenient format makes Rejuvenate an attractive alternative to conventional whey protein, especially as the latter remains at historically elevated costs. Promino's product is part of its broader mission to provide science-based, clinically proven nutrition for muscle health and recovery.
