Vitamin D's Impact on Headaches
Resolution of hypersomnia following identification and treatment of vitamin d deficiency.
Limited focus on headaches
We explored how vitamin D treatment can influence headache severity in patients. In this case study, a 28-year-old woman experienced excessive daytime sleepiness without clear causes such as sleep disorders. Her symptoms included significant fatigue, chronic pain in her thighs and lower back, and daily headaches.
After identifying that she had low levels of vitamin D, we initiated supplementation, which quickly led to notable improvements. Within just a couple of weeks, her headaches improved significantly alongside her daytime tiredness. By the end of the treatment, both her headaches and other chronic pain issues had resolved or greatly diminished.
However, while the study indicates an association between vitamin D treatment and headache relief, it does not specifically isolate the effect of vitamin D2 solely on headaches. Therefore, while we saw encouraging improvements, we must note that further research is needed to establish a more direct link between vitamin D treatment and headache relief specifically.

No headaches experienced
Perfect! I have struggled to take any form of Vitamin D without suffering from massive headaches for nearly 20 years. Finally, I read about someone similar who switched to D2, and it worked. I'm eagerly awaiting my blood work to show an increase in Vitamin D for the first time in years, but for now, I am taking six capsules a day without any headaches!

Good Vitamin D! It seems to work well and deliver the desired effects. I’ve told my friends about it, and they’re interested too. There have been no cramps or headaches.
