Melatonin, a hormone produced naturally by your body's pineal gland, is a popular supplement used by an estimated 3.1 million Americans.
1 One of its primary roles is regulating your body's circadian rhythm, and melatonin supplements are often used as sleep aids or to help sleep problems related to shift work, jet lag and sleep disorders.
From 2007 to 2012, use of melatonin among U.S. adults more than doubled,
2 perhaps because sleep troubles are so widespread.
A Consumer Reports survey found 80% of U.S. adults struggle with sleep, and 20% tried a natural remedy to help. Of those, melatonin was the most popular, with 86% of those who had tried a supplement as a sleep aid choosing melatonin.
3Spending on the supplement alone reached $408 million in 2017,
4 hinting at its popularity. But an important question looms: is melatonin safe for nightly use?
Comment: Because the science on the microbiome is still in its infancy, researchers are still trying to figure out what exactly is the ideal for microbiome diversity. Is it that diversity is superior for health, or is there a wide range of variation in levels of diversity that still result in healthy humans? This said, it seems to almost be a no-brainer that moderate sun exposure is vital for human health. If it helps the microbiome, all the better.
