Taking 10 mg of melatonin every night is generally considered higher than the typically advised dose, which is usually 1-5 mg per night. While melatonin can be safe for short-term nightly use, such as up to six months, long-term safety and effectiveness at higher doses like 10 mg have not been well studied. Some people may experience side effects such as dizziness, nausea, headaches, and fatigue. Because melatonin is a hormone, it is recommended to use it cautiously and under the guidance of a healthcare provider, especially for long-term use. Melatonin supplements are often used for sleep disorders and conditions like jet lag, but relying on melatonin every night without understanding or addressing underlying sleep issues may not be advisable. It is important to consult a healthcare professional to determine the appropriate dose and duration for individual needs. In summary, while 10 mg melatonin nightly could be safe for short-term use in some adults, it exceeds the usual recommended dose and has unclear long-term safety. Consulting a doctor before taking 10 mg every night is strongly recommended to avoid potential risks and side effects.
