Effect of Food Supplement clinical trials at University of California Health

The purpose of this study is to determine the ability of insect-derived protein supplements (IPC80 and Whole Buffalo Powder Ynsect®) to activate the mTORC1 pathway and protein synthesis in muscle cells. To achieve this aim, participants will consume a supplemental dose (0.25 g/kg body weight) of IPC80,Whole Buffalo Powder or whey protein. Blood samples will be drawn before and 15, 30, 60 and 90 minutes after the supplementation. Protein synthesis will be assessed using stably transfected C2C12 muscle cells with a plasmid (pcDNA3 luciferase) and to determine the ability of a protein source to activate mTORC1, stably transfected C2C12 muscle cells with a plasmid (pcDNA3-TOP luciferase) where the luciferase mRNA contains a 5'TOP. 5'TOP which is specifically regulated by mTORC1 activity will be used.

The purpose of this study is to determine the effects of repeated dosing vitamin C enriched hydrolyzed collagen (HC) over a 24hr period, compared to PrimaColl™ (PC), whey protein (WP) and placebo (PL), with prescribed exercise on collagen synthesis. To achieve this, participants will consume a supplemental dose of HC (20g with 50mg vitamin C), PC (20g with 50mg vitamin C), whey protein (20g whey isolate with 50mg vitamin C) or a placebo (20g maltodextrin with 50mg vitamin C) 1hr prior to an exercise bout (6 minutes of jump rope), this will be repeated three times over a 24h period. The amount of collagen protein synthesized will be indirectly measured by measuring pro-collagen type I N-terminal propeptide (PINP) in the serum before and 4hrs after the last exercise bout.
