Can beverages & foods with melatonin help you sleep at night?
Eating foods high in melatonin can significantly increase melatonin concentration in the human body. So, dietary sources of melatonin can help you sleep better at night.
How much melatonin does the human body naturally produce?
Each person can produce different amounts of melatonin daily. It depends on many factors:
- melatonin production decreases with aging.
- being overweight may be bad for melatonin production.
- light exposure at night inhibits melatonin synthesis. Especially exposure to blue light.
The human body can naturally produce about 10–80 mcg of melatonin per night. On the other hand, it doesn’t produce any significant amounts of melatonin at the daytime.
Furthermore, the human body doesn’t store melatonin. It is instantly released into the blood. Excess melatonin is excreted through urine.
How much melatonin do we need daily?
Most people will never experience melatonin deficiency.
So, should I take melatonin supplements?
Firstly, melatonin supplements contain high doses. Much higher doses than the human body can produce naturally or found in food.
Most melatonin supplements contain doses of 3-5 mg per tablet. This dosage can be 60 times higher than our bodies can naturally synthesize per night.
So, before taking melatonin supplements you should consult your health care provider. Especially if you’re on medication. In any case, melatonin supplements are the easiest way to boost your daily melatonin intake. Compare prices on Amazon. You better prefer supplements with a dose of 1 mg (1,000 mcg).
