Introduction
The pineal gland in the brain makes melatonin, which is important for keeping our circadian rhythm (biological clock) regulated. This clock inside our bodies controls our feelings of drowsiness and readiness to get up.
When it gets dark in the evening, the body produces more melatonin to let us know it’s bedtime. When there is more light, the body stops producing melatonin and wakes you up.
Even though it naturally promotes sleep, people have several misconceptions about melatonin intake during pregnancy. Many people wrongly think that melatonin supplements can fix every sleep problem for everyone.
In this article, we will address these prevalent myths about melatonin and offer information that comes from qualified scientific studies. Also, find out what melatonin does to your sleep and how it should be taken during pregnancy.
TL;DR

- It’s not a sleeping pill, and it’s not addictive

How Does Melatonin Work in the Body?
Melatonin helps the brain control the sleep-wake cycle. It sends a signal to the brain that it’s time to sleep. Light, habits, and stress can change how much melatonin is made. This can cause sleep problems.
People who work at night, travel across time zones, or have trouble sleeping often have unusual melatonin levels. Taking melatonin can help fix these cycles and improve sleep.
A study from the National Center for Biotechnology Information looked at how well melatonin helps people sleep. The review included 15 studies with 223 healthy volunteers.

Common Myths vs. Facts
Myth 1: Melatonin is a Sleeping Pill

Myth 3: Higher Doses of Melatonin are More Effective
- Fact: Taking more melatonin doesn’t mean you’ll sleep better. In fact, higher doses can cause side effects like headaches, dizziness, and feeling sleepy during the day. It’s important to start with a small dose and only increase it if your doctor says it’s okay.

Choosing the Right Melatonin Supplement
Not all melatonin supplements are the same. It's important to pick one from a brand you trust. Make sure the dosage is right for you to experience the benefits of melatonin. Talking to a healthcare provider can help you find the best product and the right amount to take.
Dr. Mark Anton, MD, FACS
Dr. Mark Anton, MD, FACS, a bariatric physician, advises, I generally recommend starting with the lowest dose of melatonin, around 1 mg. Melatonin is a hormone, and higher doses or long-term use can disrupt your body's natural production and sleep-wake cycles.
Combining Melatonin with Healthy Sleep Habits
Pairing melatonin supplements with good sleep habits gets the best results. Try to go to bed and wake up at the same hours each day to help control your internal body clock.
Keep yourself away from gadgets an hour before bed to protect your melatonin production and get into a peaceful night routine. In the end, prepare your bedroom for sleep by making it cool, dark, and quiet so that melatonin can work its best for you.
