The key to an effective fish oil is purity.  Every batch of oil used in Nordic Naturals’ products is third-party tested for environmental toxins ensuring that every product exceeds international quality standards.  Ever had fishy burps?  This means your fish oil is rancid.  Nordic Naturals is always fresh, never rancid.  At Watson Chiropractic we place your order directly from Nordic naturals, so freshness is guaranteed.
