Only 7% of Britishers get enough omega-3 fatty acids in their diet. These natural molecules play a vital role to manage inflammation throughout the body, but our bodies cannot produce them naturally.

Research proves omega-3s can reduce the body’s inflammation levels. A complete review of 70 studies found that higher omega-3 doses lowered inflammatory markers by a lot. Patients with rheumatoid arthritis saw notable improvements. People who took more than 2.6 grammes daily showed such good results that they stopped taking their regular anti-inflammatory medications.

This piece explains how omega-3s combat inflammation in your body. You’ll learn about food sources, recommended doses, and the benefits you can expect from daily omega-3 supplements.

Understanding Inflammation in Your Body

The body’s natural defence mechanism works through inflammation that protects and heals damaged tissues. You need to know how inflammation works to understand why omega-3s are vital to your body’s health.

What causes inflammation?

Several triggers can start an immune system response. Physical injuries, bacterial or viral infections, and harmful substances like industrial chemicals or pollutants can all trigger inflammation [1]. Your body releases specific chemicals from damaged tissues that signal white blood cells to start healing [2].

The immune system fights back with inflammatory cells and cytokines that stimulate more inflammatory cells in the affected area [1]. Your lifestyle choices can also trigger inflammatory responses:

• Refined carbohydrates in poor diet choices  
• Chronic stress and lack of sleep
• Environmental toxins and air pollution
• Long-lasting infections or autoimmune conditions [3]

Acute vs chronic inflammation

Your body responds with two different types of inflammation. Acute inflammation acts as a short-term defence that usually lasts a few days [1]. Blood vessels expand during this process and increase blood flow to the affected area. This creates the typical signs of redness, warmth, and swelling [4].

Chronic inflammation builds up slowly and can last months or years [1]. This ongoing inflammatory state happens through different ways:  

• The body can’t eliminate what triggered the acute inflammation
• Low-level irritants persist over long periods
• Autoimmune disorders make the immune system attack healthy tissue [5]

Studies show that chronic inflammation plays a big role in many health issues. Scientists have connected it to cardiovascular disease, type 2 diabetes, and autoimmune disorders [1]. Research also shows that chronic inflammation helps certain cancers and neurodegenerative diseases develop [2].

Signs of chronic inflammation

Chronic inflammation doesn’t show obvious signs like acute inflammation does. Notwithstanding that, your body gives some clear signals that inflammation is ongoing [6].

People often feel tired all the time, have unexplained pain, and stiff joints [1]. Your digestive system might also act up with diarrhoea, constipation, or acid reflux[5].

Blood tests can spot high levels of substances that indicate chronic inflammation. To name just one example, C-reactive protein (CRP) levels between 1 and 3 milligrammes per litre of blood usually point to low-level, chronic inflammation [7]. Doctors might also check the erythrocyte sedimentation rate to measure inflammatory activity [7].

Scientists have found that chronic inflammation affects many body systems at once. Research links ongoing inflammation to mood changes, including anxiety and depression [1]. Your body might also show signs through frequent infections, weight changes, and skin problems [6].

This deeper look at inflammation helps explain why omega-3 fatty acids got so much attention in medical research. These fatty acids fight inflammation and help manage both acute and chronic conditions, which makes them valuable to your overall health and wellness.

Best Sources of Omega-3s

Omega-3 fatty acids are vital for controlling inflammation throughout your body. Your diet needs reliable sources of these nutrients to get their anti-inflammatory benefits. Let’s explore your options for getting omega-3s from seafood, plant-based alternatives and supplements.

Fish and seafood options

Fish and seafood are nature’s richest sources of omega-3 fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Your body absorbs these long-chain omega-3s easily, which makes them great at fighting inflammation [8].

Cold-water fatty fish pack the most omega-3s. Here are your best options:

1. Mackerel: You get 2.0 grammes of omega-3s (DHA + EPA) in each 3-ounce serving [1]
2. Salmon: A 3-ounce serving gives you 1.7 grammes from farmed Atlantic salmon and 1.2 grammes from wild Atlantic salmon [1]
3. Herring: Atlantic herring gives you 1.3 grammes of omega-3s per 3-ounce serving [1]
4. Anchovies: These tiny fish pack 1.2 grammes of omega-3s in a 3-ounce serving [1]
5. Sardines: Canned Atlantic sardines in oil give you 0.8 grammes of omega-3s per 3-ounce serving [1]

Bluefin tuna, halibut, and various trout types are also excellent sources. The omega-3 content changes based on the species, whether it’s wild-caught or farmed, and how you prepare it [8].

Plant-based sources

Plant-based options help you broaden your omega-3 intake. These work great if you follow a vegetarian or vegan diet. Plants give you alpha-linolenic acid (ALA), which your body turns into EPA and DHA, though not as efficiently [5].

Here are the best plant sources of omega-3s:

1. Flaxseeds: A teaspoon of ground flaxseeds has 570 mg of ALA, while flaxseed oil packs 608 mg per quarter teaspoon [9]
2. Chia seeds: You get 713 mg of ALA from one teaspoon [9]
3. Hemp seeds: A teaspoon of refined hemp seed oil contains 750 mg of ALA, unrefined oil gives you 900 mg [9]
4. Walnuts: Three halves (about one-fifth of an ounce) pack 515 mg of ALA [9]
5. Soybeans: Half a cup cooked gives you 500 mg of ALA [9]

Canola oil, perilla oil, and edamame beans also pack good amounts. Mix these foods into your daily meals to get enough omega-3s [5].

Your body doesn’t convert ALA to EPA and DHA very well. This means strict plant-based eaters might need more ALA or algae-based supplements [10].

Supplement types

Supplements offer a convenient way to boost your omega-3 intake if food sources aren’t enough. Here are your main supplement choices:

1. Fish oil: This popular supplement contains EPA and DHA[AS4] . Each soft gel or teaspoon gives you 300 to 2,200 mg [11].
2. Krill oil[AS5] : Made from Antarctic krill, this oil contains omega-3s as triglycerides and phospholipids. Some research shows it might work better than fish oil for heart health [8].
3. Algal oil: Perfect for vegetarians and vegans, this marine algae extract gives you DHA and sometimes EPA. Your body absorbs its DHA just as well as salmon’s[11]. Each serving typically contains 100-300 mg of DHA [11].
4. Cod liver oil: Beyond EPA and DHA, you get vitamins A and D. The amounts vary between products [12].
5. Green-lipped mussel oil: This New Zealand mussel extract contains EPA, DHA, and eicosatetraenoic acid (ETA). ETA might help reduce inflammation even more [13].

Look at EPA and DHA levels, omega-3 forms (triglycerides, ethyl esters, or phospholipids), and third-party testing when choosing supplements [13]. Talk to your healthcare provider before starting supplements, especially if you take medications or have health conditions.

Whole foods often give you extra nutrients beyond omega-3s. Your best strategy might be combining food sources with supplements to manage inflammation effectively.

Finding Your Ideal Omega-3 Dosage

The right amount of omega-3s needed to control inflammation depends on several factors. Research has given us clear guidelines, though everyone’s needs are different.

Recommended daily amounts

Health organisations have different baseline recommendations for omega-3 intake. Most experts say healthy adults need at least 250-500 mg of combined EPA and DHA daily [2]. Higher doses work better to manage inflammation.

Research supports different dosage levels based on specific health conditions:

• You need 1,000 mg of EPA and DHA daily if you have heart disease [3]
• Your doctor might recommend 2,000-4,000 mg daily if you have high triglycerides [3]
• Blood pressure management usually needs 2-3 grammes daily, which can lower systolic and diastolic pressure by about 2 mmHg [14]

Higher doses show remarkable results in controlling inflammation. Research shows doses above 2.6 grammes daily can lower inflammatory biomarkers and reduce disease activity for up to eight months [15].

The Food and Drug Administration sets safety limits and says your daily EPA and DHA intake shouldn’t go over 2,000 mg without medical guidance [3]. European authorities say doses up to 5,000 mg daily are safe [16].

Factors affecting dosage needs

Your omega-3 needs depend on several key factors:

Current Health Status You might need higher doses if you have health conditions. To name just one example, chronic heart diseases need about 1 gramme of EPA and DHA daily [17]. You might benefit from 1,200 mg daily if you have high triglycerides [17].

Pregnancy and Lactation Pregnant or nursing women need extra omega-3s. The Food and Drug Administration suggests 8-12 ounces of low-mercury fish weekly during pregnancy and nursing [18]. This means about 300 mg of extra DHA daily [2].

Form of Supplementation Your body absorbs different types of omega-3 supplements differently. Standard fish oil supplements usually give you about 1,000 mg of fish oil, containing:

•  180 mg EPA
•  120 mg DHA [7]

Phospholipid or triglyceride-based supplements might work better at lower doses than standard options. Someone needing 2,200 mg of EPA and DHA from a standard supplement might get similar benefits from just 1,400 mg of a phospholipid-based product [16].

Dietary Patterns The balance between omega-6 and omega-3 fatty acids is vital for managing inflammation. Today’s diets often have 10 times more omega-6s than omega-3s [2]. You might need more omega-3s if you eat lots of omega-6-rich foods to get the best anti-inflammatory effects.

Blood Test Results The Omega-3 Index measures omega-3 PUFA in red blood cells and helps indicate if you need to adjust your dosage. This index relates inversely to inflammation markers like C-reactive protein and IL-6 [19]. Regular testing helps fine-tune your supplement levels.

Age and Gender Your age affects how much you need because inflammatory responses change throughout life. Gender makes a difference too – men typically need 1.6 grammes of alpha-linolenic acid daily, while women need about 1.1 grammes [2].

Talk to your healthcare provider before starting omega-3 supplements, especially if you take blood-thinning medications [20]. Regular check-ups help adjust your doses based on how your body responds and your changing health needs.

Measuring the Benefits

You need objective measurements and careful monitoring of physical improvements to track how well omega-3 supplements work. Blood tests and symptom tracking are a great way to get insights about how these essential fatty acids help curb inflammation in the body.

Blood tests for inflammation

Several blood tests measure inflammation levels and show how omega-3 supplements affect the body. The C-reactive protein (CRP) test is a vital indicator that measures a protein the liver produces during inflammatory responses [21]. A high-sensitivity CRP test (hs-CRP) gives more precise measurements. Values above 2.0 mg/L show higher inflammation levels [22].

Doctors use multiple tests to get a full picture of inflammatory status:

• Erythrocyte sedimentation rate (ESR): Measures how quickly red blood cells settle in a test tube  
• Plasma viscosity (PV): Evaluates blood thickness
• Procalcitonin (PCT): Specifically identifies bacterial infections
•  Fibrinogen: Assesses both blood clotting and inflammation [23]

The Omega-3 Index test measures EPA and DHA levels in red blood cell membranes. An index of 8% or higher shows optimal levels, while scores below 4% point to increased health risks [24]. This test reflects omega-3 intake over the previous four months and serves as an excellent tool to monitor long-term progress [4].

Tracking symptom improvements

Lab measurements tell only part of the story. Physical changes give valuable feedback about omega-3’s effectiveness. Many people notice improvements in:

Physical Markers:

• Joint comfort and mobility  
• Cardiovascular function
• Sleep quality
• Skin condition

Systematic Monitoring: Regular checks of these indicators help track progress. Some patients keep detailed records of their symptoms and note changes in pain levels or physical capabilities [4]. To cite an instance, a cyclist measured progress by tracking pain-free cycling distance [4].

Healthcare providers suggest creating a well-laid-out symptom diary to track improvements. This helps identify patterns that relate to omega-3 supplementation levels.

Timeline for results

Your body responds to omega-3 supplementation in a predictable yet gradual way. Original changes start almost immediately, though visible benefits emerge over weeks or months.

Short-term Effects (Days to Weeks): Some improvements show up quickly:  

• Better cognitive function
• Quick pain relief
• Improved heart rate patterns [25]

Medium-term Changes (1-2 Months): More substantial benefits develop as omega-3 levels increase:  

• Better sleep patterns
• Improved blood sugar regulation  
• Better lipid profiles [25]

Long-term Benefits (2-3+ Months): The most important improvements appear after consistent supplementation:  

• Major reduction in inflammatory markers
• Optimal heart health benefits  
• Better joint function
• Improved vision health [25]

Research shows that omega-3 content in red blood cells reaches its peak between 8-20 weeks of consistent supplementation [4]. During this time, inflammatory benefits become more noticeable, with best results showing up after 3-6 months of regular intake [4].

Individual responses vary, but studies prove that steady omega-3 levels are vital for lasting anti-inflammatory effects. The body’s inflammatory markers, especially CRP levels, reliably show progress [21]. Regular blood tests help adjust dosage and ensure you get the best benefits.

Doctors note that improvements continue beyond the first few months of supplementation. Like other healthy lifestyle changes, omega-3’s anti-inflammatory benefits build up over time. Some people see better results even after several months of consistent use [25].

Safety and Side Effects

Omega-3 fatty acids help manage inflammation, but you need to know about their side effects and interactions. This knowledge will help you use these supplements safely to reduce inflammation in your body.

Common side effects

Most people tolerate omega-3 supplements well and experience minimal side effects. Some people might have mild reactions when they start taking them or use higher doses.

Gastrointestinal discomfort: Digestive issues are the most common side effects. These include:  

• Burping or fishy aftertaste
• Nausea
• Stomach upset  
• Bloating
• Diarrhoea

You can reduce these effects by taking omega-3 supplements with meals or splitting your daily dose throughout the day [7]. Freezing the capsules before taking them can also help with fishy burps.

Bleeding risk: High doses of omega-3s might slightly increase bleeding risk because they thin the blood mildly. This effect gets more attention than it deserves. A complete meta-analysis found no major increase in bleeding events among patients taking omega-3 supplements compared to control groups [26].

Patients taking high doses of purified eicosapentaenoic acid (EPA) showed a small 0.6% increase in absolute bleeding risk [26]. The risk linked to EPA dose but not to antiplatelet therapy use.

Allergic reactions: Few people might have allergic reactions to fish oil supplements. Signs include:  

• Rash
• Itching
• Difficulty breathing
• Swelling of the face, lips, tongue, or throat

People with fish or shellfish allergies should talk to their doctor before starting omega-3 supplements [27].

Other potential side effects: Users sometimes report:  

• Low blood pressure
• Insomnia
• Headaches

These effects are usually mild and go away as your body adjusts to the supplement [28].

Quality fish oil supplements go through extensive processing to remove contaminants, including methyl mercury [7]. Heavy metal toxicity from omega-3 supplements isn’t a real concern.

Drug interactions

Omega-3 fatty acids can affect how certain medications work. You should talk to your doctor before starting omega-3 supplements, especially if you take any of these:

Blood thinners: Omega-3s might boost the effects of anticoagulant and antiplatelet drugs and increase bleeding risk. Common medications include:  

• Warfarin
• Heparin  
• Aspirin
• Clopidogrel

The interaction is usually mild, but you might need close monitoring when taking these medications with omega-3 supplements [29].

Blood pressure medications: Omega-3s can lower blood pressure slightly. They might work too well with antihypertensive drugs and lower blood pressure too much. Watch out for:

• ACE inhibitors (e.g., lisinopril)  
• Beta-blockers (e.g., metoprolol)
• Calcium channel blockers (e.g., amlodipine)

Check your blood pressure regularly when taking these medications with omega-3 supplements [29].

Contraceptives: Research suggests omega-3s might make hormonal contraceptives less effective. Women on birth control pills should talk to their doctor about possible risks [29].

Diabetes medications: Omega-3s can affect blood sugar levels. People taking diabetes medications like metformin or insulin should watch their blood glucose when starting or changing omega-3 doses [29].

Orlistat: This weight-loss drug reduces omega-3 fatty acid absorption. Take omega-3 supplements at least two hours before or after orlistat [30].

Vitamin E: Omega-3 supplements might lower vitamin E in your body. Keep this in mind if you take vitamin E supplements [30].

These interactions are manageable with proper monitoring and dose adjustments. The benefits of omega-3 supplements often outweigh the risks, even for people taking multiple medications.

To use omega-3 supplements safely:

1. Tell your doctor about all medications and supplements you take
2. Start with a low dose and increase it slowly
3. Pick high-quality supplements from trusted manufacturers
4. Stay within recommended doses – no more than 3 grammes of fish oil daily without medical supervision [31]
5. Watch for signs of bad reactions or interactions

The European Food Safety Authority (EFSA) says healthy adults can safely take up to 5 grammes of long-chain omega-3 fatty acids daily [32]. Your needs might differ, so get personalised medical advice.

In the end, omega-3 supplements offer great anti-inflammatory benefits. You need to understand their side effects and interactions to use them safely. Work with your doctor and follow the guidelines to tap into the potential of omega-3s with minimal risk.

Conclusion

Research shows omega-3 fatty acids work against both acute and chronic inflammation. Nine out of ten Americans don’t get enough omega-3s in their diet. The good news is you have several ways to boost these vital nutrients through food and supplements.

Your body responds to omega-3 supplements in a predictable way. The original benefits show up within weeks. You’ll see the best results after taking them for 3-6 months. Blood tests can confirm the improvements by showing lower inflammation markers. Physical changes like better joint movement and heart function prove the progress.

The right dose matters because each person’s needs differ based on their health, age, gender and medicines. Most healthy adults do well with 250-500 mg of combined EPA and DHA each day. Some health conditions might need higher therapeutic doses.

Studies show omega-3 supplements are safe when used correctly. Regular checkups with your healthcare provider ensure you take the right amount and avoid side effects or medicine interactions. This balanced approach helps you utilise omega-3’s anti-inflammatory benefits and supports your health naturally.

FAQs

Q1. How effective are omega-3s in reducing inflammation?
