Why Vitamin D3?

Vitamin D exists in two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D3 is the superior form because it's the same type your skin produces when exposed to sunlight, and research shows it's significantly more effective at raising and maintaining vitamin D levels in the blood. Natural Factors uses only vitamin D3 derived from natural sources to ensure maximum bioavailability and effectiveness.

The Sunshine Vitamin Deficiency

Vitamin D is often called the "sunshine vitamin" because your body produces it when skin is exposed to UVB rays. However, many factors limit natural vitamin D production—including living in northern latitudes, spending most time indoors, using sunscreen, having darker skin, and aging. As a result, vitamin D deficiency is extremely common, affecting an estimated 40% of Americans. Supplementation is a safe, effective way to ensure you're getting enough of this critical nutrient.

Who It's For

Vitamin D3 Drops are ideal for adults and children seeking to support bone health, immune function, mood, and overall wellness. They're particularly beneficial for those with limited sun exposure, older adults, individuals with darker skin tones, people living in northern climates, or anyone looking to maintain optimal vitamin D levels year-round.

Suggested Use

Adults: Take 1 drop daily or as directed by a healthcare practitioner. Can be taken directly on the tongue or added to food or beverages. Children: Consult a healthcare practitioner for appropriate dosing. For best absorption, take with a meal containing healthy fats.
