This Vitamin Can Help You Get Higher Quality Sleep, Study Says
Sleep is foundational for overall health and wellness, yet millions struggle with poor sleep quality. According to a
recent study published by mindbodygreen, Vitamin D supplementation shows promising benefits in enhancing sleep quality and duration. This discovery adds to the growing body of research linking vitamin D deficiency with sleep disorders and supports considering vitamin D as a natural aid for sleep improvement.
The Science Behind Vitamin D and Sleep Quality
Vitamin D receptors are widely present in brain areas that regulate sleep, including the hypothalamus. Deficiency in vitamin D has been associated with shorter sleep duration, poor sleep efficiency, and greater daytime sleepiness. The new study reveals that supplementing vitamin D helps improve sleep latency – the time it takes to fall asleep – and overall sleep efficiency.
Experts suggest that adequate serum levels of vitamin D modulate inflammatory markers and neurotransmitters, such as serotonin, that influence sleep cycles. Thus, maintaining optimal vitamin D through diet, safe sun exposure, and supplementation can be a valuable strategy to combat sleep disturbances.
Why Quality Control Matters in Supplements Like Vitamin D
As demand for vitamin D supplements rises, ensuring their quality, safety, and compliance with regulatory standards becomes crucial. Supplements often vary in potency and purity, which can influence their effectiveness for sleep and general health.
