Omega-3 Fatty Acids for Rheumatoid Arthritis

Omega-3 fatty acids are one of the most studied and recommended supplements for people with rheumatoid arthritis (RA). Their effectiveness in reducing inflammation is supported by numerous studies.

How It Works

The main mechanism of action of Omega-3 is related to their ability to suppress the production of pro-inflammatory substances in the body (such as prostaglandins and leukotrienes). Two key acids—eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—are incorporated into cell membranes and compete with arachidonic acid, from which "inflammation agents" are synthesized.

Clinically Proven Effects

• Reduction in pain and morning stiffness: Many patients report a decrease in the intensity of joint pain and a reduction in the duration of morning stiffness.

• Reduced need for NSAIDs: Regular intake of Omega-3 may allow for a reduction in the dosage of nonsteroidal anti-inflammatory drugs (NSAIDs), which reduces the risk of gastrointestinal side effects.

• Improvement in overall condition: Some studies show an improvement in overall disease activity scores.

Forms of Omega-3

There are three main forms of Omega-3, which differ in their bioavailability:

• Triglycerides (TG): This is the natural form in which omega-3s are found in fish. This form has the highest absorption rate as the body can break it down and absorb it most efficiently.
• Re-esterified Triglycerides (rTG): This form is an improved version of natural triglycerides that allows for a higher concentration of EPA and DHA. It also has excellent bioavailability.
• Ethyl Esters (EE): This is a synthetic form produced during the purification and concentration of fish oil. Ethyl esters are less bioavailable than TG and rTG forms and are absorbed less well by the body. However, they are often used in concentrated and cheaper products.

Recommendation: The most preferred form in terms of absorption is the triglyceride form (TG) or re-esterified triglycerides (rTG). This information can usually be found on the product label.

Sources of Omega-3

The best source of EPA and DHA is fatty sea fish (salmon, mackerel, herring, sardines). Plant sources (flaxseed oil, chia seeds) mainly contain alpha-linolenic acid (ALA), which is only converted to EPA and DHA in the body to a small extent.

Dosage

To achieve a therapeutic effect in RA, dosages of 2 to 4 grams of EPA+DHA per day are usually recommended. This could be, for example, 4-5 tablets per day of 600 mg each. It is recommended to divide the dose into several intakes throughout the day (e.g., 2-3 capsules with breakfast and dinner). This will facilitate absorption and help avoid possible gastrointestinal side effects. Important: the dosage should be discussed with your doctor.

Duration of Intake

The intake of such a dosage should be long-term—at least 2–3 months—to achieve tangible results, such as reduced pain and morning stiffness, as well as a decreased need for NSAIDs.

Best Time to Take

It is most optimal to take Omega-3 during or immediately after a meal that contains at least a small amount of fat (e.g., with avocado, nuts, olive oil, eggs). This will significantly improve bioavailability.

Why: Omega-3s are fat-soluble substances. Their absorption occurs in the intestine with the help of bile, which is released during the digestion of food, especially fatty food. Taking them on an empty stomach can lead to poor absorption and stomach discomfort.

Common Side Effects and How to Avoid Them

• Fishy burps: This is the most common side effect.
  Solution: Take the capsules with meals. Some manufacturers produce capsules with an enteric coating that dissolves only in the intestine, bypassing the stomach, which also helps to avoid burps. You can also try freezing the capsules before taking them.
• Digestive upset: May include heartburn, diarrhea, or stomach pain.
  Solution: Reduce the dose, take the capsules with food, and possibly divide the daily dose into several intakes.

Combination with Other Supplements

• Antioxidants: Omega-3 fatty acids can oxidize. Therefore, manufacturers often add vitamin E as a natural antioxidant to maintain freshness.
• Other fat-soluble vitamins: Taking Omega-3 with fatty meals also improves the absorption of other fat-soluble vitamins, such as vitamin D, vitamin K, and vitamin A.

Conclusion: Omega-3s are a safe and effective supplement to the main therapy for rheumatoid arthritis, helping to control inflammation and improve quality of life.
