Phase 2

Completed

• Conditions: Muscle Strength
• Interventions: Other: Test Product 2; Other: Test Product 3; Other: Test Product 1; Other: Comparator

• Registration Number: NCT04814225
• Lead Sponsor: Roquette Canada, LTD.

Brief Summary

The objective of this randomized, triple-blind, comparator controlled, parallel clinical trial is to investigate the functional equivalence of three test products compared to whey protein on muscular performance in a healthy, sedentary adult population.

Detailed Description

Whey, a by-product of cheese manufacturing, is commonly used as an ingredient in meat products, dairy products, baked goods, snacks, beverages, and infant formula. Its widespread use is due to its advantageous effects on health, economics, and high nutritional value by containing lactose, minerals, vitamins, and soluble proteins. Due to allergies, dietary restrictions and/or personal dietary choices there is a need for an alternative protein source(s), and plant-based protein options are in demand for these reasons. Roquette produces the NUTRALYS® Pea Protein family of ingredients, supplying the widest range of pea protein ingredients to the food industry suitable for use in a plethora of plant-based foods. Few studies have examined the equivalence between pea protein and whey on muscle performance in sedentary adults. The objective of this randomized, triple-blind, comparator controlled, parallel clinical trial is to investigate the functional equivalence of three test products compared to whey protein on muscular performance in a healthy, sedentary adult population.
