Red light therapy (RLT) may help relieve gout pain and some symptoms associated with an active flare, but the research is still limited. Early human and animal studies of photobiomodulation (PBM) have reported improvements in pain, swelling, joint function, and certain measures of inflammation, although more high-quality human research is needed.
While red light therapy has not been shown to lower uric acid or treat the underlying cause of gout, current research supports viewing it as a complement to treatment. So you can use it as an option for symptom management but not as a replacement for medications or other treatments used to control gout and prevent future attacks.
Here’s what the gout-specific research has found so far:
-
A small human study found that laser therapy provided rapid pain relief during acute gout attacks. Researchers randomized 25 people with acute gouty arthritis to either diclofenac or daily laser therapy for five days. Both groups experienced rapid pain relief, with no significant difference in efficacy between the treatments. However, the small sample means larger clinical trials are needed to confirm the results.
-
A 2021 human study of patients with tophaceous gout found additional pain relief with low-intensity laser therapy but no significant effect on hyperuricemia (abnormal levels of uric acid in your blood). This distinction is important: while PBM may have a role in managing gout pain, current evidence does not show that it lowers the elevated uric acid levels responsible for urate crystal formation.
-
A 2023 animal study found improvements in swelling, pain-related measures, and joint function after PBM. In rats with gouty arthritis induced by monosodium urate crystals, a single PBM treatment reduced edema and joint disability while improving pain threshold and grip strength. However, some inflammatory responses increased after treatment, suggesting PBM’s effects on gout-related inflammation may be more complex than simply suppressing it.
-
Another animal study found that low-level laser therapy reduced signs of inflammation in urate-induced arthritis. After three consecutive days of treatment, rats showed a different response in fibrinogen, a blood protein that can increase with inflammation, as well as less inflammatory activity in their joint tissue compared with untreated rats. These findings suggest PBM may influence the inflammatory response triggered by urate crystals.
Most of the gout-specific research has used low-level laser therapy rather than at-home LED devices, so results may differ between the two. However, both lasers and LEDs can deliver red and near-infrared wavelengths to stimulate photobiomodulation, even though the way they deliver that light differs. If you’re exploring light therapy for gout pain, Novaalab offers the Novaa Extra-Strength Healing Laser, as well as LED options like the Novaa Light Pad and Novaa Light Boot for targeting affected joints with red and near-infrared light.
Red Light Therapy and Gout: What We Know So Far
Early research suggests red light therapy may be a useful addition to a gout management routine, particularly for relieving pain and supporting joint comfort during a flare. While larger human trials are still needed, the existing research gives us some practical insight into where photobiomodulation may help and how it has been used.
| Question | What We Know |
|---|---|
| Does red light therapy work for gout? | Early research suggests red light therapy may help relieve gout pain, swelling, and joint discomfort. Two small human studies have reported pain-related benefits. |
| Can it reduce gout inflammation? | Red light therapy may help reduce swelling and influence the inflammatory response, although gout-specific evidence is still limited. |
| Can I use red light therapy during a gout flare? | Yes. One human study used laser therapy once daily for five days during acute gout and reported rapid pain relief. |
| Does red light therapy lower uric acid? | No meaningful uric acid–lowering effect has been established. Red light therapy is better suited to symptom management than treating the underlying cause of gout. |
| What wavelength is best for gout? | No single wavelength is established as best. Human gout research has used 632.8 nm, while at-home PBM commonly combines 630 to 660 nm red light with 810 to 850 nm near-infrared light. |
| How often should I use red light therapy for gout? | Gout research has used daily treatment for up to five days. For at-home red light therapy, follow your device's recommended frequency and dosing. |
| How quickly can it help? | Human research reported rapid pain relief during five days of daily treatment, while animal research has found improvements after a single session. |
Overall, the research is most encouraging for gout pain and symptom management, including during an active flare. Red light therapy won't replace treatments that control uric acid, but it may offer a convenient, non-invasive way to support comfort and function alongside a broader gout treatment plan.
What Causes Gout Pain and Inflammation?
Gout is a form of inflammatory arthritis caused by a buildup of urate in the body. When uric acid levels remain high over time, needle-shaped monosodium urate crystals can form in and around the joints. The immune system reacts to these crystals, triggering the intense inflammation behind a gout flare.
It develops through a chain of events:
-
Uric acid builds up in the body. Uric acid, or urate, is produced when the body breaks down purines found naturally in the body and in foods such as red meat and shellfish.
-
Urate crystals form. When urate levels remain elevated, monosodium urate crystals can accumulate in and around a joint.
-
The immune system responds to the crystals. Immune cells recognize the crystals as a problem and release inflammatory signaling proteins called cytokines, which help drive the body's inflammatory response.
-
The joint becomes inflamed and painful. The resulting inflammation produces the characteristic pain, redness, warmth, swelling, and limited movement of an acute gout attack.
The big toe is the most common site of a first gout attack, but gout can also affect the feet, ankles, knees, fingers, wrists, and elbows. Flares typically affect one joint at a time and can last for several days to a couple of weeks. Without appropriate management, attacks can become more frequent, and persistent urate deposits can eventually form tophi, firm lumps of urate crystals that develop under the skin around affected joints and tissues, and contribute to joint damage.
How Red Light Therapy May Help with Gout
Red light therapy may help manage several symptoms of gout by using red and near-infrared wavelengths to stimulate photobiomodulation (PBM). While research specific to gout is still developing, early human and animal studies suggest the most promising benefits are pain relief, reduced swelling, and improved joint comfort and function.
| Potential Benefit | How Red Light Therapy May Help | What This May Mean for Gout |
|---|---|---|
| Relieve gout pain | PBM may influence cellular processes involved in pain perception and inflammation, contributing to analgesic effects. | Less discomfort in painful gouty joints during a flare |
| Reduce swelling and support a healthier inflammatory response | PBM can affect inflammatory signaling and oxidative stress, which may help ease edema and other inflammatory symptoms. | Less swelling and tenderness around the affected joint |
| Improve joint comfort and function | By helping address pain and swelling while supporting cellular energy production, circulation, and local tissue recovery, PBM may support easier movement. | Greater comfort with movement and everyday use of the affected joint |
Red Light Therapy May Help Relieve Gout Pain
Red light therapy may help ease gout pain by influencing cellular processes involved in pain perception and inflammation. Photobiomodulation can affect mitochondrial activity, cellular energy production, oxidative stress, and inflammatory signaling, which may contribute to its analgesic effects in painful joints.
Gout-specific human research provides early support for this benefit. In a small study of 25 people with acute gouty arthritis, both daily low-level laser therapy and diclofenac produced rapid pain relief over five days, with no significant difference in efficacy between the groups. Another human study involving people with tophaceous gout also reported additional pain relief when low-intensity laser therapy was incorporated into treatment.
Red Light Therapy May Reduce Swelling and Support a Healthier Inflammatory Response
Red light therapy may help ease gout-related swelling by influencing the inflammatory response triggered by uric acid crystals in the joint. However, red light therapy has not been shown to dissolve or remove urate crystals themselves. Its potential benefit is in helping manage the symptoms they trigger.
PBM can affect inflammatory signaling and oxidative stress, which may help explain why gout models have shown reductions in edema and other signs of inflammation after treatment. In a rat model of urate-induced arthritis, three consecutive days of low-level laser therapy resulted in less inflammatory activity than was observed in untreated animals. A 2023 rat study also found that a single PBM treatment reduced joint edema, although some inflammatory responses increased, suggesting PBM may modulate inflammation in more complex ways than simply suppressing it.
Red Light Therapy May Improve Joint Comfort and Function
By helping address pain and swelling, red light therapy may make a gouty joint more comfortable to move and use. PBM may also support cellular energy production, circulation, and local tissue recovery, potentially helping affected tissues function more effectively while a joint is irritated.
In the 2023 animal study, PBM reduced joint disability and improved grip strength in addition to improving edema and pain-related measures. Although human research is still needed to confirm these functional benefits, the findings suggest PBM's potential value for gout may extend beyond pain relief alone.
Overall, the early research suggests red light therapy for gout is most promising for relieving pain, easing swelling, and supporting joint comfort and function. These potential benefits make red light therapy worth considering as a complementary tool for managing gout symptoms, while treatments that lower uric acid remain important for addressing the underlying condition.

How to Use Red Light Therapy for Gout
You can use red light therapy during an active gout flare or between flare-ups, but the goal is slightly different. During a flare, red light therapy may help with pain, swelling, and joint comfort. Between flares, it can be used for ongoing joint support, although it has not been shown to prevent future gout attacks. The most important factors are using appropriate wavelengths, targeting the affected joint, and staying consistent without exceeding the recommended dose.
-
Use red and near-infrared light. Look for wavelengths around 630 nm to 660 nm for red light and 810 nm to 850 nm for near-infrared (NIR) light. Red light can target more superficial tissues, while NIR penetrates more deeply around larger joints.
-
Target the affected joint directly. Position the light over the big toe, foot, ankle, knee, fingers, wrist, elbow, or wherever gout symptoms occur. During a flare, treat bare skin when possible but avoid uncomfortable pressure on a joint that is especially swollen or tender.
-
Start with 10 to 20 minutes per session. This is a common treatment window for at-home red light therapy and provides a reasonable starting point when consistent with your device's instructions. More isn't necessarily better, so don't extend sessions beyond the recommended time in an attempt to speed up relief.
-
Aim for consistent treatment. Depending on your device, treatment may be recommended anywhere from several times per week to once daily. Daily treatment also has precedent in gout research: The small human study of acute gout used one laser treatment per day for five consecutive days.
Whether you're treating an active flare or using red light therapy between attacks, follow your device's recommended treatment time and frequency since irradiance and dosing vary. Tracking pain, swelling, stiffness, and joint comfort can also help you understand how your symptoms respond over time.
How Long Does Red Light Therapy Take to Work for Gout?
Some people may notice changes in gout pain or joint comfort within the first few sessions, but there is no established timeline for results. Because gout flares typically last several days to a couple of weeks, red light therapy is best viewed as a way to help manage pain, swelling, and joint discomfort while symptoms are active rather than as a treatment proven to shorten the flare itself.
The limited gout-specific research suggests these effects may occur relatively quickly. One human study reported rapid pain relief with daily laser therapy over five days, while an animal study found improvements in swelling, pain-related measures, and joint function after a single treatment.
| Timeline | What You May Notice |
|---|---|
| After the first few sessions | Look for early changes in pain, tenderness, swelling, or joint comfort. Some people may respond quickly, while others may need several sessions to notice a difference. |
| Within the first week | Consistent daily or near-daily treatment can give you a better sense of whether red light therapy is helping manage your flare symptoms. The human acute-gout study reported rapid pain relief during five days of daily treatment. |
| Between flare-ups | Red light therapy can also be used for ongoing joint comfort after acute symptoms subside, although it has not been shown to prevent future gout attacks. |
Because gout symptoms naturally improve as a flare resolves, you should track pain, swelling, stiffness, and ease of movement from day to day rather than judging red light therapy by a single session. This can help you determine whether it is providing meaningful symptom relief over the course of your flare.
Combining Red Light Therapy with Other Gout Treatments
Red light therapy is best used alongside established gout treatments rather than in place of them. It may provide additional support for pain, swelling, and joint comfort, while other treatments address an active flare or the high uric acid levels that cause gout.
| Gout Treatment | Primary Role | How It Fits with RLT |
|---|---|---|
| NSAIDs, colchicine, or corticosteroids | Reduce pain and inflammation during an acute gout flare | Remains the first-line treatment for flares while red light therapy may provide additional symptom support |
| Allopurinol or febuxostat | Lower uric acid and help prevent future gout attacks | Addresses the underlying uric acid problem that red light therapy has not been shown to treat |
| Ice and joint rest | Help ease pain and discomfort during a flare | Can be used alongside red light therapy for additional at-home symptom relief |
| Diet and lifestyle | Support overall gout management | Can complement red light therapy and medical treatment when maintaining a healthy weight and balanced nutrition as well as limiting excessive alcohol |
The key is to use each approach for what it does best. Red light therapy may support symptom relief, while appropriate gout treatment addresses the inflammation of an acute flare and the uric acid buildup driving the condition.
Is Red Light Therapy Safe for Gout?
Yes, red light therapy is generally considered safe and well tolerated when used as directed. Research on photobiomodulation supports a favorable safety profile, with side effects typically mild and temporary.
When using red light therapy at home:
-
Follow your device's instructions. Don't increase the treatment time or frequency beyond the recommended dose in an attempt to get faster results.
-
Protect your eyes when required. Avoid staring directly into bright LEDs and use appropriate eye protection if your device instructions recommend it.
-
Watch for skin irritation or discomfort. Temporary redness, sensitivity, or irritation can occur. Stop treatment if you experience a persistent or concerning reaction.
-
Check for photosensitivity. Talk with your healthcare provider before using red light therapy if you have a condition that causes light sensitivity or take a medication that can increase photosensitivity.
-
Don't use red light therapy to delay medical care. A suddenly red, hot, swollen, and painful joint can have causes other than gout. Seek medical evaluation if this is your first suspected gout attack, the symptoms are unusual for you, or you also develop signs of infection such as fever.
Red light therapy can be incorporated into a gout management routine without significant downtime, but it should be used for supportive symptom management rather than as a substitute for appropriate gout treatment or medical evaluation.
Choosing a Novaalab Device for Gout

Managing Gout Symptoms with Red Light Therapy
Red light therapy shows promise as a complementary option for managing gout pain, swelling, and joint discomfort. While more human research is needed, early studies suggest red light therapy may provide symptom relief during a gout flare. However, it has not been shown to lower uric acid or prevent future gout attacks, so it should complement rather than replace established gout treatment.
