We all need a deep and effective rest for our performance the next day, a life without stress and in the interest of maintaining long-term health. The demands of the modern world excuse many people from frequently interrupting this sleep cycle, but also from accumulating enough stress to produce, among its side effects, problems in getting a continuous and restful sleep.

The pharmaceutical industry has been able to manufacture resources to facilitate entry into that dream. At FastlyHealwe provide you with the necessary information to know one of these medications, it is melatonin for sleep: recommended dose and contraindications.

What is melatonin

Melatonin is a hormone , called N-acetyl-5-methoxytryptamine, which occurs naturally in our pineal gland located in the diencephalon, that is, practically in the center of the brain. This hormone is responsible for the vital function of regulating our body biorhythms and inducing drowsiness and deep sleep, at which time, in addition to resting and replenishing energy, our system is responsible for repairing and regenerating the nervous system and other tissues, always and when there is a correct scope of that restorative sleep (we reiterate this because not everyone who sleeps, sleeps deeply, or wakes up well rested and rested).

Due to the important role of this hormone, it is necessary to maintain optimal levels of melatonin production in the body, for which the following is suggested:

  • Consumption of nuts, tomatoes, bananas and cherries, as they are direct sources of melatonin.
  • For the production of this hormone in the body are necessary: tryptophan (chicken eggs, fish, meat and nuts), magnesium and vitamin B6.
  • The secretion of melatonin by the pineal gland requires darkness, therefore, it is crucial to reduce artificial lights at night. This will give a stimulus to the suprachiasmatic nucleus in the hypothalamus that will activate the sleep cycle.
  • Studies have shown that exercising helps stimulate melatonin production, especially in the morning.

Melatonin for sleep: recommended dose

Melatonin is sold with or without a prescription, depending on the country in question. Its most common presentation is in tablets of 0.3 to 3 mg. However, there are also sublingual and drop administration. This variety of doses and presentations serves as a warning that, although it is not a very delicate drug to use, the most appropriate thing would be to consult a doctor before ingestion. The dosage for its administration , according to its presentation, is as follows:

  • Tablets (0.3 to 5mg): are prolonged release, so their administration is usually at noon, 1 tablet. Ingesting it too early could make you drowsy in the afternoon, and too late would prevent its full action.
  • Sublingual Strips (1 mg): these dissolve slowly under the tongue, and have a more accelerated effect, thus being recommended for consumption at night, half an hour before going to bed.
  • Liquid: to be supplied in drops. About 20 drops are suggested, which is roughly one gram of melatonin before bedtime.
  • Mixtures: there are presentations in both tablets and strips, to which other ingredients are incorporated (eg: vitamin B6, magnesium, herbal extracts, among others) to improve their assimilation and effects. They are naturopathic products that are generally not standardized. Opportunity to remember that it is always better to consult your doctor in these cases before taking melatonin to sleep.
