Frequently Asked Questions

What is the difference between type II collagen and regular collagen supplements?

Regular collagen supplements (types I and III) are derived from bovine hide, fish, or pork skin and primarily benefit skin, hair, nails, and tendons. Type II collagen is specifically derived from cartilage sources (usually chicken sternum) and targets joint cartilage. The amino acid and peptide profiles differ — type II collagen contains peptides specific to cartilage matrix that stimulate chondrocyte activity.

Should I take hydrolyzed type II collagen or UC-II?

They work through entirely different mechanisms. Hydrolyzed type II collagen (5-10g daily) provides structural building blocks for cartilage repair. UC-II (40mg daily) works through oral immune tolerance to reduce autoimmune cartilage destruction. You can take both simultaneously as they are complementary. UC-II should be taken on an empty stomach separately from hydrolyzed collagen.

Should I take vitamin C with type II collagen?

Yes, vitamin C is a cofactor for collagen synthesis. It is required for the hydroxylation of proline and lysine residues that give collagen its structural stability. Taking 50-100mg vitamin C with your collagen supplement may enhance the incorporation of collagen peptides into cartilage tissue. Many collagen products include vitamin C for this reason.
