What is Melatonin Powder?
Pure melatonin powder can help regulate people's circadian rhythm (also known as "body clock") and sleep. It is a hormone produced by the brain in response to darkness. Melatonin is one of the hormones secreted by the brain's pineal gland. It belongs to indole heterocyclic compounds, and its chemical name is N-acetyl-5-methoxytryptamine. Melatonin will be stored in the pineal gland after being synthesized and released by pineal gland cells controlled by sympathetic nerve excitation. The secretion of melatonin has an apparent circadian rhythm, the secretion will be suppressed during the day, and the secretion will be active at night. So one of its most famous benefits is that it can improve sleep quality, shorten the time of waking up and falling asleep before bed, and has a relatively strong function of adjusting jet lag. In addition, melatonin can prevent pathological changes, delay aging, and regulate the central nervous, immune, and cardiovascular systems. Therefore, melatonin is in great demand in the market, and many people need to use it to improve sleep problems. As a professional melatonin manufacturer, Xi'an Sonwu supplies high-quality melatonin powder at a competitive price. If you have needs, don't hesitate to contact Xi'an Sonwu.

Benefits of Melatonin
1) Improving sleep quality
The well-known function of melatonin is mainly to improve sleep quality. It can shorten the time of waking up before going to bed and falling asleep, significantly reduce the number of awakenings during sleep, shorten the stage of light sleep, prolong the phase of deep sleep, and lower the threshold of awakening the following day. It does a great job of adjusting for jet lag. This is the main reason why many people buy melatonin.

2) Adjusting circadian rhythm & delaying aging
Melatonin is a hormone in vivo that induces natural sleep. It overcomes sleep disorders and improves sleep quality by regulating people's natural sleep. The secretion of melatonin has a circadian rhythm. After night falls, light stimulation weakens, the activity of enzymes that synthesize melatonin in the pineal gland increases, and the secretion level of melatonin in the body also increases correspondingly, reaching a peak at 2-3 a.m. The level of melatonin at night directly affects the quality of sleep.
However, with age, the pineal gland shrinks until it calcifies, causing the rhythm of the biological clock to weaken or disappear, especially after the age of 35, the melatonin secreted by the body itself decreases significantly, with an average decrease of 10-15% every 10 years, which leads to sleep disturbance and a series of dysfunctions. And the reduction of melatonin levels and sleep loss are vital signs of human brain aging. Therefore, supplementing melatonin from outside the body can maintain the melatonin level in the body at a young state and help adjust and restore the circadian rhythm. It not only deepens sleep and improves sleep quality, but more importantly, it improves the whole body's functional state, improves life quality, and slows aging.
3) Regulatory effect on the central nervous system
Many studies have shown that melatonin, an endogenous neuroendocrine hormone, has direct and indirect physiological regulation on the central nervous system. It has therapeutic effects on sleep disorders, depression, and mental diseases and has a protective impact on nerve cells. For example, melatonin has a sedative effect and can treat depression and mental illness. Moreover, it can protect nerves, relieve pain, and regulate hormones released by the hypothalamus.
4) Regulatory effect on the immune system
The neuroendocrine and immune systems are interconnected. The immune system and its products can alter neuroendocrine function, and neuroendocrine signaling can also affect immune function. In the past decade, melatonin regulation of the immune system has attracted widespread attention. Studies have shown that it affects the development and growth of immune organs and regulates humoral immunity, cellular immunity, and cytokines. For example, melatonin can regulate cellular and humoral immunity and the activities of various cytokines.
5) Regulatory effect on the cardiovascular system
Melatonin is a light signal with multiple functions. Through the change of its secretion, the information of the environmental light cycle is transmitted to the relevant tissues in the body so that their functional activities can adapt to the changes of the outside world. Therefore, the level of serum melatonin secretion reflects the corresponding time of day and season of the year. Biological circadian and seasonal rhythms are closely related to periodic energy and oxygen supply changes to the cardiovascular and respiratory systems. The vascular system functions have obvious circadian and seasonal rhythms, including rhythmicity in blood pressure, heart rate, cardiac output, etc. Melatonin is mainly secreted at night and affects various endocrine and biological functions.

Is It Safe?
Most people don't experience any side effects when taking melatonin. The following are some common side effects. If these side effects occur and persist with use, consult your doctor or pharmacist:
-Feel sleepy or tired during the day;
-Headache;
-Stomach pain or feeling sick (nausea);
-Feel dizzy;
-Feel irritable or restless;
