Pros: High levels of Omega 3s. 3rd party tested. Distilled to the point where the heavy metals are well below FDA standards.
Cons: Can cause you to burp. The capsules can be a little large for some people.
Nordic Naturals is a great company as far as pure fish oils are concerned. Their fish oils are very low in heavy metals and PCPs. The Ultimate Omega is high in omega 3s and is very absorbable. The only down side is that it can make some people burp. Taking it with food helps with that.
