How do we ensure quality and purity? Through third-party testing. That’s the PureCheck® guarantee.

Purity That’s Proven

With omega-3 supplements, sometimes there’s a worry that what’s on the label isn’t quite what’s in the bottle. In fact, in a published study, more than half of those tested did not meet their label claims. This is why we use PureCheck® – so you know every NutraSea product either meets or exceeds what’s written on the label.
