Hello, Thanks for the query.
When you have fairly severe deficiency of Vitamin D, then some times taking this supplement may cause some pain.
If you experience Pain from Vitamin D this very likely means that your bones have become somewhat demineralized from having vitamin d deficiency for a very long time. When your bones are demineralized and you begin Vitamin D Therapy, this can cause calcium to begin to go back into the bones. When the calcium goes into the bones it drags fluids with it. This fluid can actually cause a small expansion of the '
collagen matrix' inside the bones and this expansion pushes out against the exterior covering of the bone which is very inflexible and has extensive
nerve endings. When this occurs, you can experience this as
bone pain or even
muscular pain. If you experience new or worsening pain from taking vitamin d, it is NOT Vitamin D Contraindication, a reason to be scared or to stop taking the vitamin d. If you continue with the Vitamin D Therapy, the pain should subside in several weeks. While uncomfortable, you will be better off in the long run if you manage the pain for this time and 'get through' to the other side.
So there is no need to reduce the dose, or take in multiple small doses. Please stick to the present schedule. Pain will go away. Thanks.
