I suggest all-natural OmegaGuard. A pharmaceutical grade omega 3's uses a state-of-the-art, proprietary, low temperature, triple molecular distillation and purification process that concentrates natural beneficial omega 3 fatty acids and helps remove harmful contaminants including heavy metals lead, mercury, arsenic, cadmium, dioxins and PCBs.
Provides a full spectrum of seven natural omega 3 fatty acids -- EPA, DHA
, ALA and more.
I've used this produce several years.
Hope this is helpful and feel free to contact me with questions.
