Research published in the Journal of Exercise and Nutrition has shown that Velositol (an amylopectin-chromium complex from Nutrition21, LLC) combined with 15 grams of protein increased muscle endurance, power, and jump height for those engaged in resistance training.
 
Prior research has shown that supplementation with Velositol combined with a 6-gram dose of whey protein increased rates of muscle protein synthesis compared to whey protein alone. This new study aimed to examine if chronic supplementation with Velositol plus a higher dose of protein could impact resistance training adaptations, recovery, and biomarkers of safety.
 
The double-blind, active-controlled study included 35 recreationally active men who were randomized to one of three groups: 2 grams of Velositol + 15 grams of whey protein isolate, 15 grams of whey protein isolate alone, and 30 grams of whey protein isolate alone.
 
Subjects consumed their respective supplement immediately following resistance exercise on days when training occurred and at the same time of day on non-training days. At 0, 4, and 8 weeks of training, body composition, whole-body protein balance, upper body and lower body performance, and visual analog scale scores for recovery, sleep quality, energy, willingness to train, and muscle soreness were assessed.
 
“Velositol increases the effects of protein on muscle protein synthesis (MPS) by enhancing the mTOR signaling pathway, which is reliant on amino acids and insulin activity,” said Danielle Greenberg, PhD, vice president of scientific affairs at Nutrition21. “When used with a resistance exercise program, Velositol’s novel complex enhances the effects of protein, increasing strength, endurance, and power, while supporting healthy and sustained muscle function.”

The study concluded that the addition of Velositol to a 15-gram dose of whey protein increased total squat reps, vertical jump power, and vertical jump height to a greater extent than when 15 and 30 grams of whey protein were consumed alone.
