Taking hyaluronic acid supplements for knee pain may be beneficial, but in certain joint conditions.
See, hyaluronic acid is a type of carbohydrate present in our tissues. It’s also within our joints, keeping them lubricated. But, its levels decline as we age, which can ultimately contribute to knee pain.
However, studies show that taking it as a supplement may counteract this. We’ll discuss all about it below. Here are the topics we cover – tap on any of them to go to its section:

Hyaluronic acid supplementation and knee pain
Hyaluronic acid is a natural polysaccharide – a type of carbohydrate – that acts as a natural shock absorber. It’s a major component of the synovial fluid that lubricates our joints.
Now, taking it as a supplement has shown to provide several benefits, such as (1):
- Knee pain relief.
- Improved joint function.
- Reduction in stiffness.
However, the extent to which it can provide these benefits really depends on the form of hyaluronic acid used.
Forms of hyaluronic acid for knee pain
Hyaluronic acid injections – Best for moderate to severe pain
This is the next line of treatment for people with mild to moderate knee pain that’s not responding to painkillers. (3)
Studies report improvements in knee osteoarthritis symptoms beginning from 4 weeks after the first injection. This gradually increases over the next few weeks until it plateaus. Booster doses are usually given every 6 to 12 months. (1)
A prescription is essential for getting a hyaluronic acid injection. Also, you need a medical evaluation first before getting it. This will ensure you get the right treatment for your knee osteoarthritis.
Pros of injections
- Can provide relief from knee pain more effectively than NSAIDs or placebos.
- Has a lower risk of side effects than painkillers.
- Requires only one dosage every 6 to 12 months.
- Provides lasting relief from osteoarthritis symptoms.
Cons of injections
- They can’t be used by those with allergies to hyaluronic acid.
- May cause pain at the site of injection.
- Requires a visit to the clinic, as it can’t be self-administered.
- Needs a prescription, as professional medical advice is required first.
Dosage of injections
Hyaluronic acid injections can range from 0.5 to 6 ml, and even the concentration per ml of injection can vary from 0.8 to 30 mg/ml. (1)
The amount should be determined by your doctor, according to your symptoms, health status, and other factors.
Oral hyaluronic acid supplements – Best for mild knee pain
Taking it orally may help some people. But some studies show that taking supplements of hyaluronic acid while on the injection treatment can in fact prolong the effects of the second. (2)
They come in the form of tablets, soft gel, or capsules. Some also come in combination forms, like glucosamine chondroitin.
Pros of oral hyaluronan
- Oral forms have a lower risk of allergic reactions, so they can be taken by those who are allergic to the injections.
- Don’t require a prescription.
- Are easily available online or in pharmacies.
- Can be self-administered.
- May prolong the benefits of hyaluronic acid injections.
Cons of oral intake
- Increased risk of gastrointestinal side effects.
- Requires daily supplementation.
- Fewer studies have confirmed the benefits of oral supplementation in contrast to its injection form.
Dosage of oral supplements
A 12-month study found that taking 200 mg per day of hyaluronic acid supplements provided better control over knee pain than a placebo. (7)
Other clinical studies that used 80 to 240 mg per day for 8 to 12 weeks also found similar improvements. (7)
However, as with all dietary supplements, start with the minimal dose and build up from there. This will reduce your risk of adverse effects.
Hyaluronic acid serums
Hyaluronic acids also come in the form of serums, but their application is limited to the skin. Topical serums don’t help knee pain, they are best for cosmetic uses.
Hyaluronic acid fillers
Like serums, hyaluronic acid fillers have no use in treatments of knee joint pain. They are used as fillers to manage wrinkles, eye bags, crow’s feet, and other cosmetic issues.
Side effects and risks of hyaluronic acid
However, some minor side effects can occur following hyaluronic acid injections. Like pain, redness, and bruising on the area.
In the oral form, adverse effects are mainly limited to stomach upset and gastrointestinal distress.
Other treatments for knee pain
- The first-line medical treatment is paracetamol.
- If symptoms are not relieved, the next step is NSAIDs.
- If symptoms persist, then a hyaluronic acid injection is usually recommended.
- The last resort for knee pain management is knee replacement surgery.
While following this protocol, the patient should do other treatments for knee osteoarthritis as well, like physical therapy, weight loss, or strengthening.
Other supplements for knee pain
Hyaluronic acid is one of many supplements that may help knee pain, such as:

Can hyaluronic acid cause joint pain?
This could happen at the site of injection, but there are no reports of hyaluronic acid itself causing knee pain.
What is hyaluronic acid for knees?
For joint health, hyaluronic acid works as a lubricant and shock absorber. It can treat pain in obese knee osteoarthritis patients and other people suffering from this disease.
Conclusion: Do hyaluronic acid supplements help knee pain?
Hyaluronic acid is widely used as both injection or oral supplement to treat knee joint pain. Injectable forms are often prescribed by orthopedic doctors to treat conditions like knee OA.
Oral supplements of hyaluronic acids have also been found to be beneficial in reducing joint pain. In fact, combining them with the injectable form can extend the benefits of the injection.
The recommended dosage in oral form is between 80 to 240 mg per day. Studies have shown that taking oral hyaluronic acid supplements for as little as 8 weeks can help provide relief from knee joint pain. (7, 8)
