The Best Melatonin Supplements

By Jeremy Campbell

A good night’s sleep is essential for optimal mental and physical health. For some, falling asleep and staying asleep can be difficult due to low amount of melatonin levels and circadian rhythms that are out of sync.

Many people with sleep problems resort to prescription sleep aids which often come with unwanted side effects. For those seeking a natural alternative, melatonin products may offer an effective remedy especially in the short term.

What You Need to Know

Natural vs Synthetic Melatonin

You’ll find products with naturally or synthetically made melatonin. For vegans or vegetarians, look for a synthetic melatonin supplement. Natural melatonin supplements are sourced from the pineal glands of animals.

Benefits of Melatonin

There are a variety of benefits to supplementing melatonin.

Here are a few:

Potential Side Effects

Potential side effects of melatonin supplementation include:

  • Drowsiness
  • Depression
  • Headache
  • Nausea


While melatonin is generally considered a safe supplement, there are still a few important things to keep in mind.

For starters, melatonin is a hormone, and as with any hormone, too much can cause an imbalance in the body. For example, women with high levels of melatonin can run into issues with their reproductive hormones. While in men, prolonged use of melatonin may result in a reduction in sperm motility.

Melatonin may also interact negatively with some medications, such as:

  • Immune system suppressors
  • Diabetes medications
  • Anticonvulsants
  • Contraceptives
  • Blood thinners

What does melatonin do?

Melatonin is also known as the “darkness hormone” because it is produced when our eyes experience darkness. It can be affected by even the smallest amount of light. Though light suppresses melatonin, it increases cortisol, a stress hormone that tells us to wake up and stay alert. 

Cortisol and melatonin work against each other for our benefit. Melatonin needs to be high to put us asleep and low when we are awake. Cortisol needs to be low when we are asleep and high to wake us up and to keep us awake. 

Additionally, serotonin is a neurotransmitter and a precursor to melatonin. It takes about 12 hours for serotonin to convert to melatonin. If these hormones get out of sync, there are natural remedies you can try. 

For example, consider taking a walk in the morning sun for 30-40 minutes and avoiding blue light emitting screens at least one hour before bed. Luckily, you can also take melatonin as a supplement which is especially useful if you are jet lagged or a shift worker.
