How It Works
How It Works
Your body converts this cholecalciferol (vitamin D3) into the active hormone that regulates calcium absorption and immune cell function. Unlike vitamin D2, D3 is the same form your skin produces from sunlight, making it more effective at raising blood vitamin D levels.
Who It's For
Adults who spend limited time in direct sunlight, live in northern climates, or have been advised by their healthcare provider to increase vitamin D intake. Perfect for office workers, shift workers, and anyone concerned about bone health or immune function.
Who It's Not For
Not suitable if you're already taking high-dose vitamin D supplements or have been diagnosed with hypercalcemia. Always consult your healthcare provider if you're on medications or have kidney conditions.
About This Product
Natural Factors SunVitamin D3 2500 IU supplies 2500 IU (62.5 mcg) of vitamin D3 in one tablet. Vitamin D intake, when combined with sufficient calcium, a healthy diet and regular exercise may reduce the risk of developing osteoporosis in people with vitamin D deficiency.
What is vitamin D3?
Vitamin D3, or cholecalciferol, is the type of vitamin D that skin produces when it is exposed to the sun's UVB rays, which is how it earned the nickname sunshine vitamin. Few foods contain much of it; fatty fish, egg yolk and fortified milk are the main ones. In Canada, the sun sits too low in the sky for much of the fall and winter for skin to make meaningful amounts, so diet and supplements carry more of the load in those months.
