How does Collagen Type Ii work?
Chicken collagen is said to work by causing the body to produce substances that fight pain and swelling (inflammation), but this is unproven. Chicken collagen also contains the chemicals chondroitin and glucosamine, which might help rebuild cartilage.
Are there safety concerns?
Collagen type II is POSSIBLY SAFE
when taken by mouth in doses up to 2.5 mg daily for up to 24 weeks. It's not clear what the side effects might be. Other collagen products, such as bovine collagen and gelatin, have caused allergic reactions. Since collagen type II contains chondroitin and glucosamine, large doses might lead to the same side effects as those seen with chondroitin and glucosamine supplements. These side effects include nausea, heartburn, diarrhea and constipation, drowsiness, skin reactions, and headache.
Special Precautions & Warnings:
Pregnancy and breast-feeding
: There is not enough reliable information about the safety of taking collagen type II if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
Egg or chicken allergies
: People who are allergic to chicken or eggs should not use collagen type II. Collagen products have been associated with allergic reactions.
Dosing considerations for Collagen Type Ii.
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.
