Natural Factors Vitamin D3 1000 IU is a potent liquid supplement carefully blended with medium chain triglyceride (MCT) and flaxseed oils. Known as the “sunshine vitamin”, vitamin D is usually synthesized by the skin through sun exposure. However, many experts recommend supplemental vitamin D as decreased sun exposure puts many at risk of vitamin D deficiency. Vitamin D3 is the preferred cholecalciferol form, which is the most biologically active form of vitamin D.

Vitamin D3 is essential for strong bones and teeth as it increases the body’s absorption of calcium and phosphorus from food. When combined with adequate calcium intake, it helps prevent the brittle, weak bones of osteoporosis. Vitamin D supplementation is important during the winter season when there is limited sunlight and the body is not able to produce its own vitamin D sufficiently. People with lactose intolerance, digestive problems, breastfed infants, individuals with darkly pigmented skin, and adults over 50 years are more likely to need additional vitamin D.

Vitamin D3 1000 IU is unflavoured and contains 500 drops per bottle. It is free from artificial colours, preservatives, sweeteners, and GMOs, making it a recommended product for vitamin D support during pregnancy and lactation.
