As of my knowledge cutoff in September 2021, there are no approved melatonin vapes products available on the market. Therefore, it is not possible to compare the potency of melatonin in vapes to other forms.
However, it's important to note that when melatonin is taken orally in the form of tablets, capsules, or liquid solutions, it is absorbed through the digestive system and enters the bloodstream. The potency and effectiveness of melatonin supplementation can vary depending on factors such as the dosage, individual metabolism, and the quality of the product.
When considering melatonin supplementation for sleep, it is recommended to consult with a healthcare professional or a sleep specialist. They can guide you on the appropriate dosage and form of melatonin supplementation based on your specific needs and help you make informed decisions regarding sleep management strategies.
