Melatonin saliva test

  1. About melatonin

Melatonin has a pronounced antioxidant function. Since it is soluble both in fat and in water, it can pass through cellular membranes and enter the mitochondria. As an antioxidant, it is also found all over the human brain. It is the only antioxidant that directly enters the mitochondria, which is the powerhouse of the cell. There, it neutralizes free radicals as soon as they form.

Melatonin is crucial for the proper working of the immune system and for protecting our DNA from oxidation damage. It affects the sleeping cycle by inducing drowsiness and lowering the body’s temperature. Generally speaking, melatonin levels in our bodies start increasing from around midday to the late evening, reaching peak values at night (from around 2 to 4 a.m.). Melatonin levels in the morning are lower than those right before we go to sleep.
