What is Omega-3 and Different Types?
Omega-3 is a group of essential fatty acids that your body needs to function properly but cannot make on its own. That is why we must get Omega-3s from food or supplements.
What are the different types of Omega-3?
Not all Omega-3s are the same. They differ in source, function, and how efficiently the body uses them. Here are the common Omega-3s available:
Eicosapentaenoic Acid (EPA): EPA is mainly found in fatty fish such as salmon, sardines, mackerel, and anchovies. EPA is especially valued in Omega-3 supplements for its anti-inflammatory benefits.
- Helps reduce inflammation in the body
- Help maintain healthy triglyceride levels
- Plays a role in mood balance and stress response.
Docosahexaenoic Acid (DHA): DHA is another Omega-3 found in fatty fish and fish oil. It makes up a large portion of the fats in the brain, which is why it is often called a brain omega-3
- A major structural component of the brain and eyes
- Essential for memory, focus, and cognitive health
- Important during pregnancy and early childhood for brain and eye development
Alpha-Linolenic Acid (ALA): ALA is a plant-based form of Omega-3, and is typically found in foods, like flaxseeds, chia seeds, walnuts, and Canola oil.
ALA itself has health benefits, but the body must convert ALA into EPA and DHA, and this conversion is very limited (often less than 10%). This is why people who rely on plant sources may still benefit from direct EPA and DHA supplementation.
Foods with Omega-3 Fatty Acids
Omega-3 is present in the foods that we consume. You can find high amounts of Omega-3 in fish like Anchovies, bluefish, flounder, freshwater trout, herring, salmon, sardines, sturgeon, and tuna.
However, if you are a vegetarian, you can find Omega-3 in vegan foods, such as beans, canola oil, chia seeds, edamame, flaxseed, soybean oil, and walnuts.
Who should avoid Omega-3 supplements?
Omega-3 supplements are well-tolerated and come with a wide range of benefits. However, if you are one of the below-mentioned, you are recommended to visit your healthcare practitioner before including it in your daily regimen:
- People with bleeding disorders or on blood thinners (may increase bleeding risks)
- Individuals with fish or shellfish allergies
- Patients on certain anticoagulant or anti-inflammatory drugs
Omega-3 Possible Interactions
Here are certain medications that can interact with Omega-3. Such as,
- Anticoagulant and antiplatelet drugs, herbs, and supplements
- Blood pressure drugs, herbs, and supplements
- Contraceptive drugs
- Orlistat (Xenical, Alli)
- Vitamin E
Side Effects of Omega-3 Supplements
Commonly reported side effects of Omega-3 supplements are usually mild. Common ones include:
- Unpleasant taste
- Bad breath
- Heartburn, Nausea, and Diarrhea
- Gastrointestinal discomfort
- Headache
- Odoriferous sweat
Things to consider when buying the best omega-3 supplements
With so many omega-3 supplements available on the market, selecting one that suits your requirements and is suitable for you can be overwhelming. Here are some of the factors that you should consider when buying one:
- EPA and DHA Content: Always check the amount of EPA and DHA in the supplement. While there is no official daily recommended intake, health care professionals suggest at least 250 mg of combined EPA and DHA daily for healthy adults. However, the ideal amount depends on your diet and individual needs, so it is best to consult with your healthcare professional.
- Omega-6 Content: Some Omega-3 supplements also include Omega-6 fatty acids. However, people generally consume enough through their diets. Therefore, to maximize the benefits, choose a supplement that focuses on omega-3, particularly DHA and EPA.
- Source of Omega-3: Fish oil is the most common source of Omega-3s in supplements. But, if you are allergic to fish or follow a vegan lifestyle, you can opt for supplements that contain Omega-3 sourced from sea algae.
- Taste and Odor: While the dreaded fish burps cannot always be avoided, there are some Omega-3 supplements that are less fishy than others. Therefore, always look for products with lemon juice or other flavors to help mask the taste or odor.
- Pill Size: Because fish oil pills often include a large dosage of Omega-3s, they tend to be quite large. And that is why they are called horse pills. If you are not a fan of swallowing pills, you can choose a supplement that spits the dose into multiple pills per day or opt for a liquid formulation.
- Added Ingredients: Always choose the supplements that are free from artificial additives or preservatives. If you have any dietary restrictions, double-check the ingredient list to ensure that the supplement complies with your needs.
- Third-Party Tests: Always choose the best Omega-3 supplements that are 3rd-party lab tested for purity and potency by independent labs like NSF, USP, or IFOS.
- Sustainability: Always look for supplements containing sustainably sourced fish. These products are often certified by the Marine Stewardship Council or Friend of the Sea.
- Value: If you plan on taking fish oil supplements daily, you must also consider the monthly cost to see which product best fits your budget.
In the End
Omega-3 fatty acids are extremely important for your body. However, as your body cannot produce these substances itself, you need to obtain them from your diet. But it is not easy to meet your daily requirements. This is why high-quality Omega-3 supplements come into the picture. Before including any supplement in your daily regimen, you must pay attention to the origin and quality, as well as the formula that contains all essential fatty acids.
