Product overview
Collagen is the major structural protein in connective tissue and the most abundant protein in the human body. Type 1 & 3 collagens are often found together in the same tissue, as each form complements the structural integrity of the other.
  • Supports skin structure and volume.
  • Supports the strength and flexibility of bones, joints, tendons and ligaments.
  • Provides hair and nail support.
Collagen may aid youthful skin by supporting the structure and volume of the skin. It is also responsible for maintaining the strength and flexibility of bones, joints, skin, tendons, ligaments, hair, nails, blood vessels and eyes, among other tissues throughout the body.
The proof is in the peptides
Doctor's Best Collagen Types 1 & 3 contains Peptan®, a branded form of collagen peptides that are optimized for high bioavailability and activity, and their hydrolyzed form makes them easily digested. This unique formula also contains Vitamin C which aids collagen production in the body. This product harnesses the powerful synergy of two collagen forms to support healthy skin; together, their amino acids support skin rejuvenation, maintenance and integrity. Type 1 collagen is a building block of connection tissue, and supports skin strength and resiliency. Type 3 collagen is found in cardiovascular tissue and newly developing skin.
