Collagen Peptides May Provide Cardiovascular Health Benefits
Collagen is an extracellular protein that makes up approximately 30% of the total protein in the body. Collagen peptides are collagen that has been broken down into more easily dissolvable amino acids. A recent study has found that collagen peptide supplementation may provide cardiovascular health benefits.
For their study, researchers from the Kemanshah University of Medical Sciences used data from 12 randomized clinical trials. The trials examined the association between collagen peptide supplementation and cardiovascular disease-related markers such as body fat, fat mass, lipid profile, blood pressure, and blood sugar.
The dose of collagen peptide used in the trials ranged from 900 mg per day to 15 grams per day. The duration of the trials ranged from 6 weeks to 12 weeks.
The researchers found that collagen peptide supplementation significantly decreased body fat percentage in men, and overweight or obese participants. It also resulted in a significant decrease in LDL cholesterol, total cholesterol, and triglycerides.
In addition, collagen peptide supplementation significantly decreased systolic blood pressure. No significant effects were seen on blood sugar levels.
The study was published online ahead of print on June 6, 2022 in the British Journal of Nutrition.
Collagen peptides were found to provide bone health benefits in a previous study.
