Description
Vitamin D is a fat-soluble vitamin that functions more like a hormone in the body, playing crucial roles in calcium absorption, bone health, immune function, and cellular health.* While called a vitamin, it’s unique in that the body can produce vitamin D3 when skin is exposed to UVB rays from sunlight. However, factors including geographical location, season, skin pigmentation, sunscreen use, and limited time outdoors mean many people produce insufficient vitamin D endogenously, making supplementation important for maintaining optimal levels.*
Vitamin D exists in two main forms: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Research suggests vitamin D3 is more effective at raising and maintaining blood levels of vitamin D.* Once in the body, vitamin D undergoes conversion in the liver and kidneys to its active hormone form, which then regulates calcium and phosphorus metabolism, supports immune cell function, and influences gene expression in cells throughout the body.* Clinical research has extensively documented vitamin D’s importance for bone density and strength, immune system function, cardiovascular health, mood balance, and muscle function.*
Widespread testing has revealed that vitamin D insufficiency affects a significant portion of the population, particularly those living in northern latitudes, older adults, individuals with darker skin pigmentation, and those who spend limited time outdoors.* Healthcare practitioners increasingly recommend vitamin D testing and supplementation, driving sustained market growth for vitamin D products.* The vitamin D market shows strong year-round demand as awareness of deficiency prevalence continues increasing and supplementation becomes standard practice rather than seasonal.*
For your private label brand, vitamin D represents a foundational supplement with broad demographic appeal and consistent demand. With quality vitamin D3, proper potency options (from 1,000 IU to 10,000 IU), multiple delivery formats, and GMP manufacturing, you can provide customers with an essential nutrient supplement backed by extensive research and strong practitioner recommendations.*
