What is Collagen?
Collagen is the most abundant protein in the human body, making up about 30% of total protein content. It serves as the primary structural component of connective tissues.
As we age, our bodies naturally produce less collagen, contributing to visible signs of aging and joint stiffness.

Frequently Asked Questions
What are collagen peptides?
Collagen peptides are short chains of amino acids derived from collagen protein. They are produced through hydrolysis, making them highly bioavailable.
How long does it take to see results?
Most studies show visible results after 8-12 weeks of consistent daily supplementation.
What types of collagen are best?
Type I collagen is most abundant in the body. Marine collagen is primarily Type I, while bovine contains Types I and III.
Are there any side effects?
Collagen peptides are generally well-tolerated. Some may experience mild digestive discomfort when first starting.
