Most people think that the Keto Melt is safe to use or eat, as there have been no major side effects recorded. But because there isn't a lot of study on its long-term safety, it's best to be careful if you use it for a long time. Some people may have minor side effects like headaches or feeling sick. These effects can often be lessened by taking smaller amounts more often instead of one big dose. If any bad reactions happen, you should stop using the product right away and talk to a doctor about other treatment choices and advice.
