As Canadians living north of the equator, sun exposure is not always guaranteed and winters can be long. This is problematic not only because of the health implications in the absence of light and outdoor exposure, but also because of the role that Ultraviolet (UV) rays play in the synthesis of vitamin D3 within the body. Vitamin D3, also known as cholecalciferol, is the preferred form of vitamin D for optimal bioavailability and function within the body. It is naturally photosynthesized in the skin tissue from the cholesterol compound 7-dehydrocholesterol after exposure to UV-B rays. However, current estimates suggest that 1 in 3 Canadians are overtly deficient in Vitamin D as a result of inadequate sun exposure, poor diet, medication use, obesity and other stressors. About 2 in every 3 Canadians have adequate, yet suboptimal, Vitamin D levels. Cyto-D3 Kids is designed to aid in the prevention of vitamin D3 deficiency. Each Cyto-D3 Kids provides 15mL (450 drops) of stable vitamin D3 liquid, with a concentration of 400 IU’s of vitamin D3 per drop. Cyto-D3 Kids delivers vitamin D3 in a medium chain triglyceride oil base sourced from organic coconut oil to encourage optimal absorption and bioavailability.
