I was nervous taking what I thought was a huge dose of Vitamin D3, 50,000 IU a day for 12 days, totaling 600,000 IU. My doctor had warned it might be toxic and told me to take one capsule a month. He was wrong. The actual lethal dose (LD50) of Vitamin D3 is about 37 mg per kg, meaning you would need to take an absurd amount to come anywhere near danger. I pushed the fear aside and continued the regimen, waiting anxiously. On day eight of the loading phase, the attacks stopped.

I remember waking up that morning, realizing I had slept through the night, and elbowing my wife awake to tell her. I hugged her and cried tears of relief. I finished the prednisone and the 600,000 IU loading dose, and by day 15 I was still pain free. The attacks didn’t return. December, January, February, March came and went without a single cluster headache. I couldn’t believe it. I had gone from planning to take my life to feeling normal again, all because of a vitamin.

When the clusters returned in November 2016, I followed the exact same plan and had the same result. By day nine, the pain was gone. Once could be luck, but twice was proof to me that something real was happening. I decided then that vitamins weren’t just expensive urine as many doctors claim. Vitamin D3 was clearly more important than I had realized. I stayed on the regimen all year, keeping my level between 80 and 100 ng/ml with a maintenance dose of 10,000 IU daily plus the cofactors. November 2017 came and went without an attack. The same happened in 2018, 2019, 2020, and 2021.

In 2022, my clusters came back. By then I had learned a lot about Vitamin D3 and was in touch with Pete Batcheller, the retired Navy fighter pilot and fellow sufferer who created the regimen. I called Pete and said, “Pete, my level is perfect at 99.3 ng/ml, but the clusters are back.” He paused and said firmly, “Take 600,000 IU of Vitamin D3.” I argued, thinking he hadn’t heard me, but he replied with even more confidence, “Take one million IU of Vitamin D3.” I trusted him. I loaded 100,000 IU per day, and by day four, the attacks stopped again. I haven’t had another one since.

If you’ve made it this far, I want you to know there is hope. Vitamin D3 is safe and remarkably effective for cluster headache. Since sharing my story, I’ve received messages from sufferers around the world. One man from Belgium who had lived with cluster headaches for 25 years told me his neurologist said he might as well try the regimen. Two weeks later, he was sleeping through the night. His email subject line was “Enchanted Craig.”

Stories like his are everywhere in the cluster headache support groups online. People are getting their lives back. The Vitamin D3 Anti Inflammatory Regimen is safe, accessible and incredibly effective. You can watch my podcast on this page to learn more, and you’ll see the proof in the comments from others who have tried it.
