- NCT04125940
- Lead Sponsor
- University of Memphis
- Brief Summary
This study evaluates acute ingestion of the dietary supplement Resync on blood nitrate/nitrite concentrations in a sample of men and women. This will be a crossover trial in which participants take all 4 conditions: 1) 7.5g Resync, 2) 15g Resync, 3) 20g Resync+collagen, 4) placebo.
- Detailed Description
The product known as Resync contains a blend of nitrate-rich foods including beetroot, red spinach, turmeric, ginger root, and aronia berry extracts. Resync is sold commercially and marketed as an ergogenic aid and/or exercise recovery aid. Manufacturers of Resync recommend users take this product 60-90 minutes before an athletic event or 30-90 minutes after exercise. Resync bases these claims on prior studies investigating the individual ingredients' abilities to increase blood nitrate/nitrite levels; however, there are no clinical trials on the finished product itself.
The purpose of this pilot study is to determine the impact of acute, single ingestion of Resync products on blood nitrate/nitrite concentration in a sample of men and women. This will be a crossover trial in which participants take all 4 conditions: 1) 7.5g Resync, 2) 15g Resync, 3) 20g Resync+collagen, 4) placebo.

- Primary Outcome Measures
Name Time Method Change in diastolic blood pressure from daily baseline with 7.5g Resync 75-minutes post supplement ingestion We will determine the change in daily diastolic blood pressure with supplementation from the daily baseline diastolic blood pressure with 1 serving (7.5g) of Resync. Resync powder will be mixed with 12oz of water.
Change in systolic blood pressure from daily baseline with 15g Resync 75-minutes post supplement ingestion We will determine the change in daily systolic blood pressure with supplementation from the daily baseline systolic blood pressure with 2 servings (15g) of Resync. Resync powder will be mixed with 12oz of water.
Change in systolic blood pressure from daily baseline with 20g Resync+Collagen 75-minutes post supplement ingestion We will determine the change in daily systolic blood pressure with supplementation from the daily baseline systolic blood pressure with 1 serving (20g) of Resync+Collagen. This blend contains approximately 17g of collagen, 2 g of Resync, and 1g carbohydrates. Resync+Collagen powder will be mixed with 12oz of water.
