Frequently asked questions

Is it the same as fish oil capsules?

No. It is a highly purified, prescription form of one omega-3 (EPA); ordinary fish oil supplements have not shown the same benefit.

Can I take fish oil instead?

Not as a substitute. Ask your doctor before adding any supplements.

Do I still need my statin?

Yes. It is meant to be used together with a statin, not instead of one.
