I am continually impressed with PRL products. I'm getting my Nutrition Therapy Practitioner certification, and part of what we've learned is how to identify high-quality supplements. Premier Research Labs meets the highest requirements! We are also learning about excipients and the issues associated with some of them. I'm always impressed with the LACK of extra excipients in PRL products. Additionally, we've learned about the active and inactive forms of supplements, and for the most part, PRL products use the active forms. Thank you so much for giving us such wonderful products! One thing to consider, though, it might be a good idea to continue developing products that have fewer ingredients as some people may be sensitive to one of the many ingredients. That's not to say that you should discontinue the ones you have!
