What should you know about Holland and Barrett hyaluronic acid?

Hyaluronic acid is a naturally occurring substance involved in moisture retention and lubrication. A shop-bought capsule or tablet is taken by mouth and should not be treated as the same intervention as an injection placed into a joint. Product formulas can vary, so check the label for the amount, additional ingredients, allergens and directions.

A supplement cannot diagnose the reason for joint pain, stiffness or swelling. Symptoms may arise from an injury, arthritis or another problem that needs assessment. Evidence and suitability can depend on the joint, your health, medicines and the product formulation.

Read the full label, follow its serving directions and avoid combining products that contain the same ingredients without professional advice. Tell a clinician or pharmacist about pregnancy, allergies, kidney or liver disease, and every medicine or supplement you use.

For persistent joint symptoms, arrange an assessment rather than relying on a supplement alone. You can read about [Hyaluronic Acid](/materials/hyaluronic-acid/) and ask whether a [Hyaluronic Acid Injection](/treatments/non-surgical-orthopedics/hyaluronic-acid-injection/) is relevant to your diagnosis.

Seek prompt medical care for a suddenly hot, red or very swollen joint, severe pain after an injury, fever with joint symptoms, or inability to bear weight. These features need assessment rather than self-treatment with a supplement.

Could my symptoms be caused by an injury or joint condition? Is this supplement compatible with my medicines and health history? What treatment is appropriate if symptoms continue?
