Considerations for people taking melatonin include the following:
- Since the manufacturing of supplements (such as melatonin) is not closely regulated, it is important to choose a trustworthy manufacturer of melatonin supplements. It is a good idea to look for the "USP" symbol, since this means the supplement has been tested and contains the right ingredients in the right amounts.
- Most melatonin products are synthetic, although a few products are available that contain melatonin from the pineal glands of animals (often sheep or cows). The synthetic versions are considered safer, as the animal forms are more likely to contain contaminants.
- If you have any chronic health problems or take any prescription medications, you should check with your healthcare provider before taking melatonin.
- If you are unsure about anything related to dosing with melatonin, please talk with your healthcare provider or pharmacist.
