Dosage & How to Take It

Dosage for fish oil varies depending on the condition you wish to treat. The dosage should be based on the amount of EPA and DHA found in fish oil. This is because the amount and ratio of EPA and DHA varies significantly among manufacturers.

The typical dose used to treat high cholesterol / triglycerides and most other conditions is between 1 - 4 grams daily.

Heart failure

The dosage used to reduce the risk of heart failure is 1 gram daily.


Dosages up to 10 grams daily (divided into three doses) have been used for treating depression.


Some experts suggest using 3 to 5 grams of fish oil daily.

How much is too much?

Do not take more than 4 grams daily unless you are under the direct supervision of your healthcare provider.

Typically, 1 gram of fish oil contains about 0.034 - 0.112 grams (34 - 112 mg) of EPA and 0.015 - 0.062 grams (15 - 62 mg) of DHA. The ratio is usually 2:1. Commonly, 1 gram of fish oil will have omega-3 fatty acids containing 0.18 grams (180 mg) of EPA and 0.12 grams (120 mg) of DHA. The super concentrated omega-3 caplets may have up to 0.4 grams (400 mg) of EPA and 0.2 grams (200 mg) of EPA.

The best fish oil supplements will clearly indicate the amount of EPA and DHA. Base your purchase decision on the amount of EPA and DHA contents. The pills usually include some vitamin E to prevent oxidation leading to spoilage of the product.

Many manufacturers also use ultra purification methods to ensure that their product is pure and free from heavy metal contaminations.

There has been discussion about buying only "pharmacy grade" or pharmaceutical grade omega-3's. All fish oil sold for human consumption is pharmaceutical grade.

Fish oil is proven safe to use in many hundreds of clinical studies.

When is the best time to take omega-3 capsules?

It is best taken with food or water. Pick a time of day that is easy for you to remember so you won't forget.
