Which vitamins absorb calcium?

QUESTION: Which vitamins absorb calcium?


  • Vitamin D is primarily responsible for aiding the absorption of calcium in the body.
  • It plays a crucial role in regulating calcium levels and promoting its absorption from the intestines into the bloodstream.
  • Without adequate levels of vitamin D, the body may struggle to absorb calcium efficiently, even if it is consumed in sufficient amounts.
  • It is important to maintain adequate levels of both calcium and vitamin D for optimal bone health.
Vitamin Role in Calcium Absorption
Vitamin D Enhances calcium absorption from the intestines into the bloodstream.
Vitamin C May assist in calcium absorption, although its role is not as well-established as vitamin D or vitamin K.
Vitamin A May contribute to bone health and calcium metabolism, but excessive intake can negatively impact bone health.
Vitamin K Supports the activation of proteins involved in calcium binding and bone mineralization.
Vitamin B12 Plays a role in calcium absorption, although it is not a direct enhancer like vitamin D.
