The 10 Best Fish Oil Supplements

Fish oil is one of the richest food sources of omega-3 fatty acids. Studies have proven that fish oil consumption reduces inflammation in your body besides supporting the brain, eyes and heart health.

Fish oil has two types of essential omega-3 fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The American Heart Association and the World Health Organization both recommend having one to two servings of fatty fish weekly.

But to ensure you get adequate amounts of omega-3s, it is best you add in a fish oil supplement. These supplements offer combinations of fish oils extracted from different fishes such as sardines, anchovies, and mackerel. Ensure you opt for a brand that uses only wild-caught fish extracts.

Some manufacturers add certain compounds to the fish oil to increase the bioavailability and absorption of EPA and DHA from the fish oil. You may find an enteric coating around the soft gels used to encapsulate the fish oil. This is to prevent the disintegration of the capsule in the gastric environment after you consume it. This ensures better absorption of the nutrients in the capsule. Companies such as Newtrition use patented technologies such as Accelon to increase absorption.

There are plenty of manufacturers offering various types of fish oils in the market. Here we have compiled the top 10 high-quality fish oils that offer you all the omega-3s you need. Compare them and see what suits your needs and your budget the best.

The recommended intake for EPA and DHA is from 250 to 500 mg per day. On an average, about 1000 mg of fish oil offers you about 300mg of DHA and EPA.

1 to 5 grams of fish oil daily for a period of 6 months is recommended for treating hypertriglyceridemia which is characterized by high levels of triglycerides in the blood. There have been studies in which 3.4 grams of EPA and DHA combination decreased triglycerides by 25 to 50% when taken daily for 2 months.

Daily doses of 1400mg of EPA and DHA combination have been found to reduce depression symptoms in just three weeks while 2,500 mg doses of EPA and DHA are more effective for lowering anxiety.

More than 3 grams (3000 mg) of fish oil may affect blood clotting and this can increase bleeding. Other possible side effects include bloating, rashes, bad breath, diarrhea and nausea depending on how sensitive you are to the medication. Some people experience no side effects even at higher doses, so gradually increase your dose to see how much you can tolerate without discomforts.
