Our products are licensed according to Health Canada regulations and the DIN-HM is the unique identifier for each product.⁠ ⁠ "Homeopathic medicines are treated differently under the NHP (Natural Health Products) Regulations because they can contain or be manufactured from substances that are not otherwise regulated under the NHP Regulations.⁠ ⁠ The unique designation for homeopathic medicines will help consumers identify the product as a homeopathic medicine. While similar to the requirements for NHPs, these products also have to meet specific Good Manufacturing Practices and unique standards of evidence."⁠Source⁠ So you can be assured that you are purchasing what is claimed on the bottle and we are only using regulated ingredients. It was important to make sure we did the homework so that our customers can have peace of mind when purchasing.⁠
