Pharmaceutical grade fish oils

In our opinion we think for fish oils to be classed as pharmaceutical grade the concentration – strength has to be above 70%, although lots of fish oils claim to be of pharmaceutical grade, you will find that there are not many fish oils on the market which match our criteria of having this strength. Therefore we feel it shouldn’t carry this tag!!

Health food shop grade fish oils

This is the category that most fish oils fall into. They are relatively cheap to buy and you have to take fairly large quantities daily. This is where we would class most of the fish oils that are sold on the internet. The omega 3 EPA content per capsule is relatively low, as is the concentration – strength of the EPA.

Cod liver fish oils

Although lots of older people swear by it, we class these fish oils as one of if not the lowest grade of fish oils on the market. The reasons for this are that it contains very small amounts of omega 3 essential fatty acids and you would have to consume large amounts to get to one gram of EPA, and in doing so you would probably be going over the recommend daily amount for other vitamins that cod liver oil is very high in, mainly vitamins A and D.

As you will notice we have not mentioned anything about the purity of these fish oils, as that’s a different matter altogether. It’s possible that fish oils are very clean but are not very strong, we are purely classing the above grades of fish oils on omega 3 EPA content and the strength of the EPA.
