Look at the label and you will see quality features such as website and phone number posted. I have provided pictures for you to read. If there is no website or phone number, I won’t take a supplement. Third party testing is important to me because of a concern for heavy metals. From years of research, this supplement has ingredients that help brain function so their name “Brain Health Support” is valid. There are many beneficial forms of magnesium, but this has the most beneficial to support brain function as per my research. I already take these ingredients so finding them in one pill is more convenient. I have read that it is more beneficial for some to take more Lion’s Mane than this supplement provides, but for many, this amount may be all one might need. Price is reasonable for the quality ingredients. Since I already take these ingredients, I can say that they have helped me.
