Omega 3: Frequently asked questions

What types of Omega 3 are there and what determines a good product?

There are three types of Omega 3 fatty acids, EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and ALA (alpha-linolenic acid). The body can convert ALA into EPA and then to DHA. However, this conversion is not very efficient in most people so it is best to get your omega 3s from fish oil or krill oil supplements which contain both EPA & DHA as well as other nutrients such as vitamin E. Krill Oil also contains astaxanthin which has anti-inflammatory properties that help reduce joint pain associated with arthritis.

The quality of the fish oil is determined by its purity, freshness and potency. Purity refers to how much environmental pollutants are in it (heavy metals like mercury). Freshness means that you want a product with an expiration date as close to now as possible. Potency refers to what percentage of EPA/DHA omega-3s there are per capsule or serving size. A higher amount will be more effective for your health goals than a lower one.

Who should use a Omega 3?

Anyone who wants to improve their health and wellbeing.

Based on what criteria should you buy a Omega 3?

Price, features and warranty are three of the most important factors to consider when shopping for a Omega 3. However, other factors also come into play. There is more to it than just comparing prices; you should look at the whole picture before making your final decision.

Make sure you compare the dosage of active ingredients in each product. Some Omega 3 products contain omega-3 fatty acids which are not readily available to your body, while others have a higher concentration per capsule. The best way is to go through customer reviews and see what people say about their experience with that particular brand.

What are the advantages and disadvantages of a Omega 3?


Omega 3 is a type of fatty acid that the body needs to function properly. It can be found in fish and some plants, but it's not naturally produced by the human body. The most common types are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These acids have been shown to reduce inflammation throughout your entire body, which may help prevent heart disease as well as other chronic conditions like diabetes or rheumatoid arthritis.


There are no disadvantages of a Omega 3.
