Omega-3 fatty acids are good fats that are essential for optimal health and should be obtained from the diet as they are not produced by the body. Scientific evidence indicates that omega-3 contributes to a healthy heart, healthy joints and a healthy mind. Vitamin D3 is responsible for many regulatory functions in the body including bone mineralization and immune system health. Sunlight is the primary source of vitamin D, but given limited sun exposure due to seasons, indoor living habits and the use of sunscreen, up to 40% of people, from children to seniors have been found to be deficient in vitamin D throughout the year.
