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.

Not effective for me
I may be an outlier, but I experienced a terrible headache after taking this. It might be a side effect of detox, but it didn’t seem effective for me. Doctor's Best is a reputable brand that I trust, so I don't believe it’s the brand itself. It might simply not suit me, perhaps it works too well, or I could be too sensitive to it.

Headaches from dosage
1 people found this helpful
I work in a hospital, so I purchased this for detoxification from vaccine shedding. Although I was meant to take two pills daily, I experienced headaches. Upon researching, I discovered that glutathione can cause headaches occasionally. I paused for a while but resumed with one pill daily, which relieved my headaches. The capsule size is manageable, and I didn’t notice any unpleasant smell, so I recommend it for those concerned about shedding.

Assists with headaches

Besides NAC, it includes selenium and molybdenum. It alleviates headaches when detoxification phases falter. I would take NAC and magnesium anywhere.

Caused severe headaches
A lot of positive reviews prompted me to buy this for my husband for prevention, but it did not suit him. After a week of use, it caused severe headaches, and we tried it several times.

Excellent for headaches
Fantastic! A quick remedy for colds and headaches. NAC acts as a precursor to glutathione and plays a role in detoxification.
