This has likely saved my life! Take "Nervous System Health" seriously, especially regarding B-1 deficiency which can cause dysautonomia. I'm using NOW Vitamin B1 to manage sleep apnea effectively. Since starting, I'm experiencing significant improvements; no more waking up gasping for breath or unusual diaphragm flutters during sleep! These have become essential for my well-being.

I recently struggled with restless sleep, and learned that stress might cause it due to high cortisol levels. After taking B1 for just a few doses, my sleep became calmer. I’ll certainly continue taking it.

I have consistently purchased this B1 for myself and friends for years. I find it effective when taken after meals. I often take it at night for sound, undisturbed sleep. If overly tired, I consume two with yoghurt, which helps my nervous system.

Reduced anxiety levels

I gave my 20-year-old son B1 and GABA for about a month. He felt more relaxed, and his anxiety and sleep improved. B1 is particularly beneficial for those who enjoy carbohydrates.

Eases sleep issues

Good vitamin B1. I believe everyone could benefit from it. The dosage is a bit large for me, so I take half a tablet at dinner. I fall asleep more easily and wake with a clear mind, significantly helping with my sleep apnea.
