“Is this just another fish oil? I already have some Costco pills. ”No comparison. Most over-the-counter fish oils might help a bit, but they don’t guarantee any results – and many are poor quality. In fact, an analysis of popular fish oils found a significant portion were rancid or near rancid, meaning you’re ingesting oxidized fats (yuck!). Zinzino is different by design: pharmaceutical-grade oil, protection against oxidation, and a test to prove it’s correcting your levels. It’s a complete program, not a random pill. If you’ve been taking fish oil and not feeling a difference, ask yourself: Have you measured your Omega-3 Index?Probably not. With Zinzino, you will – so you’ll finally know if your supplement is doing what it should. We take the guesswork out, so your money is well spent.
