Answer: Our SuperFoodsRx Omega-3 formula is not molecularly distilled, but rather cold-filtered. While molecular distillation can remove some of the “fishiness” of fish oils, it may also lead to degradation of the product as it usually involves exposing the oils to high levels of heat. We felt it would be better to opt instead for a more natural cold-filtering process that minimizes heat exposure and thus maintains the freshness and integrity of the delicate oils. The purity of our product has ensured very few complaints about “fishiness.”
