Effects of 10-gram Collagen Protein Hydrolysate on Cardiometabolic Health

Effects of 10-gram Collagen Protein Hydrolysate on Cardiometabolic Health in Obese (BMI 25-35 kg/m2) Men and Women With Elevated Risk to Develop Type-2 Diabetes and CVD

The effects of a 10g/day collagen hydrolysate for a period of 4 weeks on glycemic control and cardiovascular health in a parallel design study using overweight/ obese men and women who are likely to have a disturbed lipid and glucose metabolism and increased risk to develop cardiovascular disease and/or Type- 2 diabetes.

Study Overview

• Status: Completed
• Conditions: Glucose Metabolism; Lipid Metabolism
• Intervention / Treatment: Dietary supplement: 10 g of collagen hydrolysate; Dietary supplement: Placebo

Detailed Description

Food-derived bioactive peptides represent a source of health-enhancing components that have been reported to have cardiovascular health benefits in humans and may be incorporated in functional foods. Up till now studies using collagen hydrolysates particularly addressed issues around joint health, however, there are some preliminary indications that other health-related targets might be affected as well. We here propose to focus on the potential effects of collagen hydrolysates on glycemic control, and characteristics of the microcirculation, both important parameters for the assessment of future cardiovascular disease (CVD) risk.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
