Vitamin D is unique among vitamins — your body can produce it from sunlight, yet deficiency remains remarkably common. An estimated 42% of US adults have insufficient Vitamin D levels. This matters for skin health more than most people realize.
Keratinocytes express Vitamin D receptors (VDRs) throughout the epidermis. When activated, these receptors promote cell differentiation, antimicrobial peptide production and wound healing. Our formula provides 10mcg (50% DV).
Your skin produces Vitamin D from UVB exposure, but the same UVB radiation causes DNA damage and accelerates aging. The NIAMS recommends sun protection, which reduces Vitamin D synthesis. Supplementation addresses this paradox by providing Vitamin D without UV exposure.
People who wear sunscreen daily, live at high latitudes, have darker skin (which reduces UV synthesis), work indoors or are over 65 all face higher deficiency risk. A daily gummy like Gelagen provides consistent Vitamin D intake independent of sun exposure.
At 50% DV, our dose contributes meaningfully but may not be sufficient for severely deficient individuals. A blood test (25-hydroxyvitamin D) can determine your specific level and whether additional supplementation is appropriate.
