Calamarine has several different versions of fish oil and some have less DHA than ours, and some have more.
Calamarine oils are all in concentrate form, ie ethyl esters, whereas ours is a blend of high concentrate ethyl esters and natural triglycerides. We
have found that although our blend has a lower level of DHA or Omega 3 that the concentrate alone (50% and 85% respectively) that our blend actually has double the anti-inflammatory properties when compared to the high concentrate form.
There is some natural component of the oil that is lost in the concentration process which contributes significantly to its anti-inflammatory properties which is why we go to the extra trouble of doing the blend that we do.
