NEW! Test Your Melatonin Levels!

If You’re Having Trouble Sleeping Your Melatonin may be Low

SleepCheck is a saliva test kit that measures the level of melatonin in your system.

Why Test Melatonin Levels?

• If you’re not sleeping well (insomnia).
• If you’re sleepy and mentally foggy during the day.
• If you’re taking a melatonin supplement or considering it.
• Concerns about declining melatonin levels with age.

On the Melatonin Main Page you'll find links to articles about melatonin in the body, and the latest melatonin research.

Melatonin is known as the hormone of sleep. Made primarily in the pineal gland in the brain, this important hormone is secreted in response to darkness. In fact, light suppresses melatonin production, so if you’re a night owl or sleeping in less than darkness, your body will produce less melatonin.

But melatonin isn’t just about sleep. It’s a powerful antioxidant and tumor suppressor. Melatonin is so important in preventing cancer that the World Health Organization has declared night shift work a “probably carcinogen.” Women with low melatonin levels have a higher risk of breast cancer, and men with prostate cancer tend to be melatonin deficient.

How to Test Melatonin Levels
SleepCheck is a safe, easy-to-use, and reliable melatonin test kit that uses a saliva sample to measure the level of melatonin in your body. This noninvasive and inexpensive melatonin test provides the accuracy of a laboratory analysis with an at-home test. When you receive the melatonin test kit in the mail, you’ll collect the required saliva sample and send it to the lab in a prepaid return mailer. Within 7 to 10 working days after the lab receives your sample, your melatonin level results will be mailed to you.
