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.

Sleep improved significantly

I have a thyroid problem and take selenium as prescribed by my doctor. This drug has been effective; my nodes have decreased, chronic fatigue is gone, my sleep has improved, and the uncomfortable lump in my throat has subsided. The price is very reasonable compared to other medications, and I definitely recommend this product.

I take selenium when I have insomnia. It is a powerful antioxidant that resolves sleep problems. I take it two hours before bedtime, and it helps me relax. My immune system has strengthened as well, and I highly recommend it.

Works clearly eliminates the lack of selenium; I began to sleep better, experience fewer mood swings, and have more energy in the morning. My tests have shown improvement.

Insomnia alleviated

I suffered from insomnia, waking up in the middle of the night. After taking selenium for three months, I no longer wake up at night. I believe it has calmed my nervous system.

Beneficial for sleep
The quality is good, though it can be harsh on my stomach. It suited my mother, and it was beneficial for both of us, helping us sleep deeply.

I recommend selenium! It normalises thyroid and pancreas functions, aids in the absorption of fat-soluble vitamins, and reduces overall fatigue. Lack of selenium clearly impacts thyroid performance, which in turn affects hormones. Adhering to the principle of doing no harm, I've been taking one capsule without excessive reliance. Night sweats have ceased, and my sleep has become more profound and longer. I will continue to take it.

I noticed my sleep improved because of this, but I advise caution. I heard that you must take iodine with it to prevent sluggishness in the thyroid gland.

This is excellent for selenium deficiency. I no longer have memory difficulties, and my light sleep issues have vanished. I take it with Lugol’s solution, which is essential for a healthy thyroid.

Improved sleep quality

This vitamin is absolutely incredible. I took it for two weeks straight before noticing any improvements, so I recommend giving it a few weeks to work. It has greatly enhanced my mood and energy levels and even improved my sleep. The only downside is that it upsets my stomach, so during the day, I take half a pill instead.
