How It Works
How It Works
Your body converts cholecalciferol (vitamin D3) into active hormone that regulates calcium absorption and immune cell function. Unlike vitamin D2, D3 is the same form your skin produces from sunlight and raises blood levels more effectively.
Who It's For
Adults with limited sun exposure, those living in northern climates, or anyone wanting to maintain optimal vitamin D levels year-round. Ideal for supporting bone health as you age or strengthening immune function.
Who It's Not For
Not suitable if you're already taking high-dose vitamin D or have hypercalcemia. Consult your healthcare provider if pregnant or on medications.
About This Product
Natural Factors SunVitamin D3 2500 IU supplies 2500 IU (62.5 mcg) of vitamin D3 as cholecalciferol in one small softgel. 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 D is nicknamed the sunshine vitamin because skin makes it under ultraviolet light from the sun. Cholecalciferol, or D3, is the same form produced that way. Few foods carry much of it naturally, and at Canadian latitudes the winter sun is too weak for skin to make a meaningful amount, which is why many people add a supplement during the darker months.
Key features
- 2500 IU (62.5 mcg) of vitamin D3 per softgel
- Cholecalciferol form
- Sold in bottles of 90, 180, 360 and 500 softgels
- Non-GMO, gluten-free, dairy-free and soy-free
Why a softgel?
Vitamin D is fat-soluble, so it is commonly carried in an oil base sealed inside a softgel. A single softgel holds the full 2500 IU, and the four bottle sizes let you choose a supply for one person or for a whole household.
