Spectrum Essentials - Fish Oil with Vitamin D 1000 mg. - 250 Softgels   Spectrum’s Fish Oil with Vitamin D combines their purity-tested Fish Oil, with its rich stores of Omega-3 EPA and DHA, with a potent dose of Vitamin D. These combined nutrients support heart and bone health while also promoting healthy vision, brain and immune functions. The Vitamin D3 (cholecalciferol) used in this formulation is a naturally occurring form of Vitamin D that is readily absorbed by the human body. Spectrum's Fish Oil with Vitamin D comes from non-threatened species of wild-caught fish that are low on the food chain. Harvesting these types of fish also ensures that our oil conforms to the Council for Responsible Nutrition’s stringent purity standards related to harmful contaminants like PCBs, dioxins and heavy metals.
