Overview

Overview Information

Native collagen type II is a protein that is part of cartilage, bone, and other tissues in animals and humans. Most collagen type II in supplements comes from chicken. Some collagen type II comes from cows.

Collagen type II is used for osteoarthritis. It is also used for other types of joint and muscle pain, but there is no good scientific evidence to support these other uses.

How does it work?

Collagen type II is said to work by causing the body to produce substances that fight pain and swelling. But this is unproven.

Uses

Uses & Effectiveness?

Possibly Effective for

  • Osteoarthritis. Taking collagen type II by mouth for up to 6 months seems to improve self-reported symptoms of osteoarthritis such as stiffness and pain. It might work better than taking a combination of chondroitin sulfate and glucosamine. Most research has investigated a specific product called UC-II. But there's no evidence that collagen type II can prevent joint space narrowing in people with osteoarthritis.

Possibly Ineffective for

  • Rheumatoid arthritis (RA). The best evidence suggests that taking collagen type II doesn't greatly improve symptoms of RA. In fact, using it in place of drugs for RA such as methotrexate might make symptoms worse.

Insufficient Evidence for

  • Joint pain. Taking collagen type II may help people with joint pain move their knee better during exercise. It might also help these people exercise for longer before feeling joint pain. But more research is needed to confirm.
  • Swelling (inflammation) of the eye (uveitis). Early research shows that taking collagen type II doesn't improve eye symptoms in children with uveitis related to juvenile rheumatoid arthritis.
  • Pain associated with joint pain after surgery, pain after injury, and back and neck pain.
  • Other conditions.
More evidence is needed to rate the effectiveness of collagen type II (native) for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Collagen type II is POSSIBLY SAFE when taken by mouth, short-term. Collagen type II has been safely used in research in doses up to 40 mg daily for up to 24 weeks. Some people might have stomach problems after taking collagen type II. Headache, difficulty sleeping, dizziness, swelling, and liver problems have also occurred. But these events are uncommon.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if collagen type II is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Collagen allergies: People who are allergic to other types of collagen should not use collagen type II. Other collagen products have been associated with allergic reactions.

Interactions

Interactions?

We currently have no information for COLLAGEN TYPE II (NATIVE) Interactions.

Dosing

Dosing

The appropriate dose of collagen type II depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for collagen type II. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
