Since I haven't found a thread already discussing this subject, here it is:
Thank you, haidut!haidut said:Amazoniac said:Hello haidut,
How to assure that a customized supplement supplier uses high quality and pure ingredients? In other words, hwo to determine that they are reliable and what are the clues for that?
If you don't mind, I'll find a proper place in the forum to place this conversation, I just didn't have the time yet..
Wish you a great day!
The only way to have a definitive answer on that is to hire a company to do a chemical analysis and issue a Certificate of Analysis (CoA) on the actual supplement. However, that won't necessarily tell you what is the quality of the ingredients used but only whether they are present in the supplement. A full CoA tends to be very expensive and can cost several thousand dollars per supplement analyzed. In the absense of that, the vendor can supply individual CoA for each of the ingredients used in the supplement, which is what I did for my supplements. I sent the CoAs to Charlie and Dan Wich about a year ago. The CoA for each ingredient used lists its exact type, purity and chemical formula.
Finally, a good quality supplement rarely causes allergic reactions even in sensitive people and some of the ingredients of the supplement can be gleaned from its taste/smell/texture and so on. For instance, SolBan has a bitter/tangy taste due to the aspirin/caffeine/niacinamide, Energin is orange in color and has the nasty taste of thiamine (B1), Oxidal is navy blue in color and had bitter taste due to the caffeine and benzoic acid in it.
I hope that helps.
