Melatonin is a hormone produced by the pineal gland in your brain that regulates the sleep-wake cycle. It can also be taken as a supplement to help with sleep disorders, jet lag, and other sleep-related issues. While melatonin is generally considered safe, it is important to ensure that you are taking the right amount to avoid any adverse effects.

But how much melatonin should you take? This is a common question among people who are considering taking melatonin supplements, and the answer may depend on several factors, such as your age, weight, and overall health. In this article, we will explore the recommended dosage guidelines, as well as the signs and symptoms of melatonin overdose.

It is important to note that melatonin is not regulated by the FDA, so the recommended dosages may vary between manufacturers and products.

What is melatonin?

Melatonin is a hormone produced by the pineal gland in the brain. It plays a crucial role in regulating the sleep-wake cycle. The production of melatonin is influenced by the amount of light we receive. When it’s dark, the body produces more melatonin to promote sleep, and when it’s light, the production decreases to promote wakefulness.

Aside from regulating our sleep, melatonin also has other physiological functions in the body. It has antioxidant properties and helps boost the immune system. Some studies even suggest that melatonin may play a role in the prevention and treatment of certain diseases, such as cancer and cardiovascular disease.

Sources of Melatonin

Melatonin is found in some foods, such as cherries, bananas, and oats. However, the amount of melatonin in these foods is small compared to the amount produced by the body. Therefore, supplements are commonly used to increase melatonin levels.

It’s important to note that melatonin supplements should only be taken under the guidance of a healthcare professional. Improper use of melatonin supplements can lead to potential side effects, such as dizziness, nausea, and drowsiness.

Conclusion
