We examined the levels of selenium and key vitamins in patients suffering from obstructive sleep apnea (OSA) without additional health issues. Our study, involving 146 subjects split into different OSA severity levels, aimed to understand how these antioxidants might play a role in OSA's impact on health.
Interestingly, we found that higher concentrations of selenium and vitamin A appeared to bolster the body’s defense against OSA. Although our findings suggest potential benefits, it's important to note that antioxidants alone should not replace conventional treatments for OSA.

Improved sleep quality
I have been taking selenium for six months now and have noticed significant improvements in my well-being and health. Previously, I often felt fatigued and overwhelmed, particularly in the evening. Now, I have sufficient energy throughout the day and have become more efficient and active. My mood and sleep have also improved. I used to wake up frequently at night and struggled to fall asleep, but now I sleep soundly. My mood has become more stable and positive, with irritability greatly reduced. Another pleasant bonus is the enhancement of my skin and hair condition. My skin is now more elastic and fresh, and my hair has less fall and better growth. Even my nails have strengthened. I take selenium in capsule form, 200 mcg per day, with water. I haven't noticed any side effects and am very pleased with the results, highly recommending it for anyone looking to boost their energy, mood, and overall well-being. Selenium is an excellent health supplement!
