Hey Frenchie,
Vitamin D3 is a MUST when treating Crohn's and Cluster Headaches. Follow the new "Quick Start Guide with lots of vitamin D3 and the cofactors. Short URL = https://is.gd/cluster2023
You'll need to elevate your serum 25(OH)D3 to a range between 80 and 100 ng/mL. One Vitamin D3 loading cycle (600,000 IU over 12 days at 50,000 IU/day) followed up with a vitamin D3 maintenance dose 100,000 IU/week should do the trick. This will take care of both your cluster headaches AND Crohn's. Take care and please Keep us posted.
