There were studies showing that better sleep will greatly reduce the chances of depression.

While the majority of depressed people suffer from sleep disorders.

Studies suggest that people with insomnia have a ten-fold risk of developing depression compared with those who sleep well.

#3. It is good for your eyes and skin

It is found that it can also do good to your eyes and skin.

The working mechanism is not clear yet, but it is highly related to its antioxidant property, to neutralize the oxidative damage and stimulate the growth receptors.

Its antioxidant effects are thought to be more potent than glutathione, vitamin C, even vitamin E.

Some researchers believe that good skin and eyesight are due to sound sleep. Sleeping beauty did exist, right?

However, researchers believed that topical forms have better skin effects than oral dosages.

How Much Melatonin Is Too Much?

For adults, you can start with two-tenths of a milligram and five milligrams 60 minutes before bedtime. 

Children should take a smaller dose as a beginning.

So start with the smallest dose of two-tenths of a milligram and increase it as needed or recommended by their doctors. 

Amounts can vary from 0.2 mg to 6 mg.

Doctors have suggested that there is not any evidence to take more than 6mg for better effects.

Are Melatonin Gummies Safe For Kids?

Many children encounter sleeping issues, such as difficulties sleeping at night, and easy wake-ups during their sleep.

It is found to be beneficial for children with attention deficit hyperactivity disorder, autism, other developmental disabilities, or visual impairment to take it regularly.

However, before even considering prescribing it for your kids, please exclude other causes of the sleeping issues, such as the noise, light, or anxiety due to school study pressures, or do they eat or drink too much before sleep.

You can also visit the sleep health foundation website for details.

Many studies have proved that short-term and low-dose melatonin is safe for children.

However, kids tend to chew more than enough melatonin gummies for sweet flavors to put them in danger of overdosing.

Parents need to take extra care of melatonin gummies to avoid any melatonin overdose.

Its slow-release formulation is also safe for long-term use such as for one year.

Although it is not recommended to take it for long-term use, there are no safer and better options than it other sleep aids.
