Selenium shows promise for migraines
We explored the effects of selenium supplementation in a double-blinded trial involving 72 patients with migraines. Over 12 weeks, participants received either selenium or a placebo. We observed that those taking selenium experienced reduced headache frequency and severity.
Additionally, selenium improved antioxidant levels and lowered oxidative stress markers. However, it appears that many other factors related to migraine symptoms did not see significant changes. While this research shows promise, further studies are necessary to confirm these findings.

We examined how dietary selenium affects the occurrence of migraines, especially looking at age differences. Analyzing data from nearly 10,000 adults in the NHANES survey, we found that higher selenium intake is linked to fewer migraines.
This beneficial effect seems particularly significant for adults aged 20 to 50, where increasing selenium to about 101.9 µg/day appears to help prevent migraines. However, the relationship is complex and influenced by age, highlighting the importance of adequate selenium-rich foods for this age group.

Sodium selenite shows symptom improvement
We explored how sodium selenite affects symptoms in patients with brain tumors. This study included 32 patients who experienced increased intracranial pressure after previous treatments.
Notably, 76% of participants reported significant improvements in their symptoms, including headaches, while 24% experienced slight improvements.
Treatments also positively impacted blood cell counts and enhanced the effects of oxygen therapy. Overall, sodium selenite could be a promising part of supportive care for brain tumor patients experiencing multiple symptoms.

Prevents hangover headaches
18 people found this helpful
I adore wine, perhaps too much. I began taking NAC to safeguard my liver during drinking sessions, especially when my in-laws visit. My father-in-law insists on keeping our glasses filled, making it easy to lose track of consumption. If I take NAC beforehand, I feel perfectly fine the next day—no headaches or tummy troubles. It also seems to delay the feeling of intoxication, which can mislead you about your intake. I don’t drink and drive, but if you do, I caution against it while on NAC, as you might not feel how much you've had.
