Hey Lori,

Here's the basic regimen and dose from Costco that worked well for me and many others:

If you can't get to Costco, look for name brand vitamin D3 in 5,000 IU strength, Citracal Plus, and any name brand Omega 3 Fish Oil.

The last thing to pick up is some Centrum Silver or Safeway brand  Century Senior 50 + Formula.  Both should contain the vitamin A and vitamin K.  If your husband takes one of these a day he can drop back to one of the calcium citrate or Citracal tablets.

Several CH'ers have found the fastest way to a pain free response to this regimen was to double the vitamin D3 daily dose to 20,000 IU/day with a once a week loading dose of 50,000 IU for the first month (that works out to 190,000 IU/week vitamin D3) or until they experienced a complete cessation of cluster headache symptoms for at least 48 hours, whichever occurs first then drop back to the 10,000 IU/day vitamin D3 maintenance dose.

Remember to ask for the 25(OH)D lab test when your husband sees the neurologist

Take care and Please keep us posted.
