Colecalciferol is a vitamin D supplement. The information on this page is about Vitamin D capsules (1.25 mg ) for adults that you can get from a prescriber.
It's prescribed if you have low vitamin D levels. Vitamin D is important for the absorption of calcium from your stomach and for the functioning of calcium in your body.
- A mild lack of vitamin D may not cause symptoms, but it can cause general aches and pains.
- An ongoing lack of vitamin D can increase your risk of weak, brittle bones and osteoporosis.
Colecalciferol works by helping your body absorb more calcium from your diet.
