About Cod Liver Oil
Cod Liver Oil is a cardiovascular supplement used to support cardiovascular and circulatory health. Omega-3 plus vitamins A and D from cod liver. It is available in softgel form and dosed for adults in India and internationally. As a western-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol.
How it works
Cod Liver Oil works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the heart, blood vessels, and effects are dose-dependent, typically becoming measurable within 4-12 weeks for measurable cardiovascular markers. Consistency matters more than dose size for this category.
