Background
- Hyaluronic acid is polysaccharide (sugar-based) component of connective tissue, including the skin. Its water-binding and elastic properties have skin-plumping effects. Hyaluronic acid also lubricates tissues and joints.
- Hyaluronic acid is used in osteoarthritis treatment, ophthalmic (eye) surgery, and tissue engineering. It may be injected into a joint or into the skin, taken by mouth, or applied topically. Hyaluronic acid fillers are popularly used to minimize the appearance of facial wrinkles and to plump skin in the cheeks and chin.

Results of human study showed that a hyaluronic acid product, Juv?derm Ultra Plus?, reduced the appearance of nasolabial folds (creases between the nose and lips) more so than a bovine collagen-based filler. Additional research is needed to confirm these early findings.

Intra-articular (intrajoint) hyaluronic acid injections have been reported to be highly effective in the treatment of osteoarthritis in humans. A small study also found that oral hyaluronic acid therapy helped reduce pain and increase physical functioning in adults with knee osteoarthritis. Additional research is needed in this area.

| Tradition / Theory
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Dosing
Adults (18 years and older)
- For general use, 50 milligrams of hyaluronic acid has been taken by mouth once or twice daily with meals.
- For osteoarthritis, 80 milligram capsules of Hyal-Joint? (a natural chicken comb extract containing 60-70% hyaluronic acid) has been taken by mouth daily for eight weeks.
- For dry eye syndrome, hyaluronic acid 0.2% (HyalistT) has been applied to the eye three or four times daily for 90 days.
- For osteoarthritis, 20 milligrams of hyaluronic acid has been injected into the knee joint weekly for three weeks.
Safety
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Interactions
Interactions with Drugs
- Hyaluronic acid may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin?) or heparin, antiplatelet drugs such as clopidogrel (Plavix?), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?). Drugs that increase the risk of bleeding should be discontinued at least one week before a hyaluronic acid injection.
- Hyaluronic acid may interact with disinfectants containing quaternary ammonium salts. Use these disinfectants with caution when using hyaluronic acid.
