Does Vitamin D Help You Sleep? I Tried It
Many people struggle with sleep, but identifying the specific type of sleep disturbance can be challenging. One individual’s experience highlights this difficulty, as years passed before recognizing that frequent middle-of-the-night awakenings – specifically waking up around 3 am – constituted a form of insomnia known as sleep maintenance insomnia.
Understanding Sleep Maintenance Insomnia
What the Experience Reveals
This individual experiences these awakenings almost five times a week, with a return to sleep occurring only about 25% of the time. This pattern underscores the frustrating reality of sleep maintenance insomnia, where the initial act of falling asleep isn’t the problem, but rather staying asleep throughout the night.
Exploring Potential Solutions
In an effort to improve sleep, this individual has experimented with various approaches, including consuming kiwis and passionflower tea. Alongside these, a daily vitamin D supplement has been incorporated into their routine for approximately six months.
The Role of Vitamin D
Research and Deficiency
Emerging research suggests a potential link between vitamin D and sleep quality. Vitamin D deficiency, particularly prevalent during the darker months in regions like the UK, appears to be a “forgotten aspect in sleep disorders.” It may contribute to issues with both maintaining sleep and regulating sleep patterns.
Connection to Other Conditions
A 2024 paper suggests a complex relationship between vitamin D and obstructive sleep apnea (OSA), raising the question of whether one condition contributes to the other. However, a 2022 review and meta-analysis of studies indicated that vitamin D supplementation may be associated with improved sleep quality. Another study suggests vitamin D aids in the creation of melatonin and may benefit those with restless leg syndrome or OSA.
Personal Experience and Considerations
While the benefits haven’t been dramatic, this individual has observed slight improvements in sleep since starting vitamin D supplementation. They’ve also maintained a more consistent bedtime, a practice known to support healthy sleep regulation. Additionally, they’ve experienced fewer illnesses during the winter months, potentially linked to the vitamin’s immune-boosting effects.
It’s important to note that vitamin D3 may be more effective for immune function than vitamin D2. The NHS recommends a daily intake of 10 micrograms of vitamin D for most adults, with a maximum daily limit of 100 micrograms, and notes that sufficient vitamin D can be produced through sunlight exposure from late March to September.
