Folic acid linked to OSA severity
We examined the connection between dietary components and the severity of obstructive sleep apnea (OSA) in a group of 303 adults from Cyprus.
The study indicated that higher energy intake increases OSA severity. However, we noticed that participants with higher folic acid intake tended to have less severe cases of OSA.
Thus, while diet impacts OSA severity, folic acid may offer a protective benefit that could be significant in managing this condition.

Weight loss resolves sleep apnea
We examined the effects of bariatric surgery on children aged 8 to 18 facing severe obesity. The study involved 22 children, half of whom had sleep apnea.
Remarkably, children with sleep apnea experienced a significant drop in BMI after surgery, leading to the resolution of their sleep difficulties.
Additionally, many reported improvements in school performance and overall quality of life. While there were a few postoperative complications, the surgeries were deemed safe, promoting the idea that similar interventions can benefit severely obese children.

Health benefits attained
Mumtaz is a wonderful product. The small grains lack smell or taste, making them easy to consume. Their benefits for the brain, heart, mood, and sleep are essential and effective for anyone caring about their health.

Improved sleep quality
I ordered 21st Century folic acid, 400 μg, 250 tablets for the first time. The large packaging arrived undamaged. Based on reviews, the quality seems good. The small tablets are easy to swallow and have a neutral, slightly salty taste. After a few weeks, I noticed a return to normalcy in my nervous system, increased strength, improved sleep, and more energy.

Positive sleep impact
I take 1 tablet every evening before bed and began to sleep better. I’m unsure of the accuracy, but I do see results.
