Vitamin D3

Helps absorb calcium for stronger bones

Key Benefits

  • Supports calcium absorption
  • Helps maintain bones and teeth
  • Supports normal muscle function
  • Helps maintain adequate vitamin D status

How It Works

Vitamin D3 is first converted in the liver to 25-hydroxyvitamin D, the main circulating marker used to assess status. The kidneys and other tissues then convert it to an active hormone that increases intestinal absorption of calcium and phosphate.

This regulation helps maintain mineral availability for bone remodeling and other cellular functions. Response to supplementation varies, and excessive intake can cause hypercalcemia, so dosing should reflect authoritative guidance and individual needs.

Vitamin D3 FAQs

Common questions about this ingredient in skincare.

What is Vitamin D3?
Vitamin D3 is cholecalciferol, a fat-soluble form of vitamin D used by the body to support calcium balance, bones, and muscle function.
How does Vitamin D3 help bones?
It promotes intestinal absorption of calcium and phosphate, minerals needed for normal bone formation and remodeling.
Is Vitamin D3 different from Vitamin D2?
Yes. D3 is cholecalciferol and D2 is ergocalciferol. Both can raise vitamin D status, though their sources and pharmacokinetics differ.
Should I take Vitamin D3 with food?
Because it is fat-soluble, taking it with a meal containing some fat may support absorption. Follow the product label.
How do I know if I need it?
Diet, sun exposure, age, skin pigmentation, absorption, and health conditions all matter. A clinician may use a blood 25-hydroxyvitamin D test when appropriate.
Can I take too much Vitamin D3?
Yes. Excess supplemental vitamin D can raise blood calcium and cause serious harm. Do not exceed recommended amounts without medical supervision.
