What is hyaluronic acid?
Hyaluronic acid, or HA, is a long, slippery sugar chain your body makes itself. It holds water, and that's most of its job: it keeps skin plump and helps cushion your joints. About half of all the HA in your body sits in your skin.
Skin creams use it too, but a capsule works a different way. It goes through your gut rather than sitting on your skin.
The idea isn't new. Yang Guifei in ancient China and Catherine, wife of Henry II of France, are said to have eaten chicken combs for their beauty, and those combs are full of HA. Ours is from chicken as well, so it isn't vegetarian.
What it does
- Skin moistureHelps skin hold water and supports normal hydration.
- Skin smoothnessSupports skin elasticity and a smoother feel.
- Joint comfortPart of the fluid that cushions your joints, and supports comfortable movement.

What people take it for
Some evidenceDry skinSeveral small studies found moister skin within 2 to 6 weeks. Most used 120 mg or more a day.
MixedWrinklesA 12-week study found fewer wrinkles and firmer skin, but a wider review of sun-aged skin didn't find a clear benefit.
Early daysKnee comfortSmall studies point to mild relief. In one year-long study, where everyone also did leg exercises, it mostly helped people under 70.
How long it takes
Skin moisture changed in as little as 2 to 3 weeks in studies. In a study of hyaluronic acid on its own, wrinkles took longer, with changes showing at 8 and 12 weeks. Knee studies ran from a few weeks up to 12 months.

How long it stays in your body
Your body is always replacing it. HA lasts under a day in skin, 1 to 3 weeks in cartilage, and only minutes in your blood. In one study the skin benefit still showed 2 weeks after people stopped.
What's in a capsule
The label lists 60 mg of hyaluronic acid from chicken collagen in each capsule. Most skin studies used 120 mg or more a day, so one capsule is about half of that. Some knee studies used mixtures holding around 48 to 60 mg, and others used 200 to 240 mg.
The big puzzle: how does it get in?
HA is a huge molecule, far too big to slip through your gut wall in one piece. Lab tests show large pieces barely get absorbed, so for years people assumed swallowing it was pointless.
What seems to happen is that your gut bacteria snip it into tiny fragments, and your small intestine takes up some of those. Lactobacillus and Bifidobacterium seem to play a part. Researchers are still working out how that turns into moister skin, and one theory is that it nudges your skin cells to make more of their own.
Your body also makes and breaks down HA at a remarkable pace, which is why results may fade if you stop. It isn't something you fill up once and keep. Injected HA, used for knees and in cosmetic fillers, is a very different thing from this.
What it interacts with
- Chicken allergyThis capsule comes from chicken, so check with your doctor if you're allergic.
- Regular medicinesWe didn't find known drug interactions, and the studies report no side effects from HA. Few of them looked for interactions, though, so mention it to your pharmacist.
- HA injections and fillersThese are separate treatments. Tell whoever gives them that you also take a capsule.
Goes well with
Side effects
- Studies lasting up to a year reported no side effects caused by HA, though most were small.
- Because those studies were small, rarer problems could still be missed.
Check first if
- Pregnancy or breastfeeding: there isn't enough research, so check with your doctor.
- Vegetarian or vegan: this one comes from chicken.
- Ongoing joint pain or swelling: get it looked at instead of relying on a capsule.
The blood tests that go with it
- hs-CRPShows low-level inflammation, a useful check if your joints are sore.
- Uric acidHigh levels can cause gout, one cause of painful joints.
- Rheumatoid factorHelps sort out the cause of ongoing joint pain.
- Anti-CCPRead with rheumatoid factor when joints stay swollen.
- TSHA slow thyroid can cause dry skin, so it's worth ruling out.

Questions
What is hyaluronic acid good for?
Mostly skin moisture, with some early support for wrinkles and knee comfort. It's what your body already uses to hold water in skin and joints.
How long does hyaluronic acid take to work?
Skin moisture changed after 2 to 3 weeks in studies, and wrinkles after 8 to 12 weeks. Knee studies ran for months.
What are the benefits of hyaluronic acid pills?
Moister skin has the best support. Results for wrinkles are mixed, and knee relief looks mild. Most of the studies are small, so it's fair to keep your expectations modest.
Does hyaluronic acid have side effects?
Studies have reported none caused by HA, including one that ran for a year. Most were small, so rare problems could still be missed.
Does hyaluronic acid interact with medicines?
We didn't find known interactions, but it hasn't been studied much. If you take regular medicines, it's worth mentioning to your pharmacist.
Can I take hyaluronic acid every day?
That's how it was taken in studies, for up to a year. There's less research beyond that.
Is hyaluronic acid vegan?
Not this one. Ours comes from chicken. Other versions are made by fermentation using bacteria.
Does it help with knee pain?
Possibly a little. Studies found mild relief, and one long study saw it mostly in people under 70 who also did leg exercises. Ongoing pain still deserves a proper look.
