What is Melatonin?
Melatonin is a hormone secreted by the pineal gland in the brain. It improves sleep quality, shortens the time it takes to wake up before bed and fall asleep, and has a strong effect on regulating jet lag. However, Melatonin secretion decreases with age, contributing to shorter sleep durations in the elderly. Highassay’s Melatonin ingredients can be widely used in various sleep-enhancing health foods, especially for those experiencing Melatonin deficiency due to jet lag, shift work, and aging.

Health SupplementsIn accordance with the Food Safety Law of the People’s Republic of China and the Measures for the Administration of the Catalogue of Health Food Ingredients and Health Functions, Melatonin was included as one of the five health food ingredients in my country on December 1, 2020. As a health food ingredient, melatonin has the effect of improving sleep. The daily dosage ranges from 1-3mg and it can be formulated into gummies, tablets, granules, hard capsules, and soft capsules.
CosmeticIn addition to being used in health supplements, Melatonin is also added to cosmetics such as night creams and serums due to its antioxidant properties. Orally taken Melatonin supplements rarely reach the skin. Application to skincare products provides protective ingredients, preventing oxidative damage to skin cells, thereby inhibiting dark spots and delaying aging.
Animal Nutrition AdditivesA proper amount of Melatonin taken by puppies can help relieve their anxiety and tension, improve their sleep, behavioral disorders and some skin problems, and have a certain effect on their hair loss, helping their hair to thicken and regenerate.
Why is Melatonin better than Sleeping Pills?
Melatonin is a hormone that induces natural sleep. By regulating a person’s natural sleep cycle, it overcomes sleep disorders and improves sleep quality. Unlike other sleeping pills, Melatonin is non-addictive and has no significant side effects. Taking one to two tablets (containing approximately 1.5-3mg of melatonin) before bedtime generally induces sleepiness within 20 to 30 minutes. Melatonin loses its effectiveness in the morning, so you won’t feel tired or drowsy upon waking.


What are the side effects of long-term Melatonin overdose?
- It can interfere with the body’s normal Melatonin secretion, leading to sleep disorders.
- It can affect the body’s normal mental state, causing poor mood and drowsiness.
- It can affect one’s mood, leading to anxiety, irritability, and even depression in severe cases.
- It can disrupt the endocrine system and may lead to drug dependence.
Who should not take Melatonin?
- Pregnant and breastfeeding women
- People with depression or mental illness
- People who drive or operate machinery
- Adolescents and those with autoimmune diseases

When to take Melatonin?
Melatonin stays in the human body for a short time, so it is recommended to take it about 1-2 hours before going to bed for better results.
What medicines should not be taken together with Melatonin?
Melatonin will inhibit the efficacy of aspirin, ibuprofen, and indomethacin tablets, so they are not suitable for use together.
Tart Cherry Melatonin Powder
Tart cherries are one of the few food sources with higher Melatonin content. However, due to their sour taste, they are usually not eaten directly. Instead, they are made into freeze-dried powder. The Melatonin content in freeze-dried tart cherry powder is relatively stable and is easily absorbed, making it a convenient way to supplement.
