Examined antioxidants in sleep apnea
The role of antioxidant vitamins and selenium in patients with obstructive sleep apnea.
Study relevance is moderate
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.

Easier breathing
I have dealt with nasal discharge since childhood, leading to tonsil inflammation, which disrupted my sleep. A friend suggested NAC, and after taking it before bed, I finally could breathe properly and sleep again. I’m truly grateful and plan to keep using it.

Improved nasal clarity
It's indispensable for us! Both my husband and I have suffered from clogged noses at night, but since using this product, we sleep like babies. My husband also had spring allergies, but since starting two capsules—one in the morning and another before bed—he no longer has issues. Highly recommended, and thanks to iherb for providing it.

Effective against fatigue
I have been using this product for 2-3 years and have exchanged other supplements, but I will definitely repurchase this one. I find it very effective for hangovers, fatigue relief, and improving sleep quality.

Enhanced sleep quality
I've taken this before but stopped for a while. Recently, I saw a discount and remembered to take two capsules each morning with collagen on an empty stomach. After just two weeks, my skin is much softer, and I find it easier to fall asleep with deeper sleep quality. Excellent ingredients and generous portions.

Enhanced sleep quality
Wonderful! I stopped taking this for a while but started again after seeing a discount. I’ve been taking two capsules with collagen every morning on an empty stomach for two weeks. My skin feels delicate, and I find it easier to fall asleep, with the quality of my sleep improving significantly.
