What country do these ingredients come from?

Please call Ace Pharmacy for a very detailed explanation of where the active ingredients come from and how the raw ingredients are tested multiple times after arriving in the U. S. (732) 952-2244. From my understanding 95% of ALL pharmaceutical active ingredients come from China. That includes most all prescription and OTC drugs which I did not know. I have trusted this company since the beginning because I have seen improvement in disabilities, and they will explain answers to all of your questions. Promise!

What does "biotin as d-biotin usp" mean on ingredients?

D-Biotin is the naturally occurring and biologically active form of Biotin. There are 7 other isomers (or versions) of Biotin, but this is the most active form and also the form used in the clinical studies that were conducted. USP stands for United States Pharmacopeia. It essentially means that the biotin we use in our product has met the highest level of quality as set forth by the USP and FDA. More information can be found in the link below. http://www.usp.org/about-usp

Is this product GMP quality assured? I can't see from the pictures provided.

Martha , My apologies for not responding sooner. This product is in fact produced in a GMP facility that while they are NOT required to do so , voluntarily submits to the FDA for inspection. As you may or may not be aware the FDA does not regulate the vitamin and mineral supplement industry.This fact was instrumental in us choosing this company for our manufacturing needs.

What is the difference between biotin and d biotin?

It is one of the 8 forms of Biotin. It is a helper enzyme. So not a real difference.
