Sorry for the length, but I like to set out all the data I already have before asking my questions…
A few years ago, my doctor suggested I add Chromium picolinate supplements to my diet to further aid my glucose control. Technically, I’m a Type II diabetic, but my hemoglobin A1c levels have been below 6 – even below 5.5 – and only on rare occasions in the past has that risen to about 8.
The thing is, those low A1c numbers coincided with the time I was taking Chromium picolinate (and the converse, of course). But being of a more scientifically minded sort (who else would be a '99 Charter Member of the SDMB?), I understand that there’s no necessary cause and effect relationship acting there. I further understand that even if there were, it would most likely be a subtle effect, given the controversy as to whether there are any demonstrable benefits of Chromium picolinate at all, even for diabetics.
In any event, my understanding is and was that it was safe enough at the normal dosage and cheap enough that I didn’t see much value in experimenting with myself by stopping taking the supplement to see what happened. I figured that any small or even moderate measurable difference would be impossible for me to fully explain one way or the other, so why not just keep going with what seemed to have a beneficial effect, an effect that many experts claimed was precisely what I *would * see?
But a month or so ago I went to Walgreen’s for a refill and there was no Chromium picolinate to be found anywhere! It had utterly vanished from every maker’s shelves. It had universally been replaced with other Chromium salts. No more picolinate.
My question is: Why? I seek a definitive answer, and I just can’t find one. My favorite, hard-working pharmacist investigated it for a couple of days and he can’t figure it out, either. He received no definitive answer about it from Walgreen’s, either, even after asking the head office. It’s like The Invasion of the Picolinate Snatchers.
Now, a few hypotheses are easy to come up with, such as that the picolinate was found to be too dangerous (various people have warned against it for various health reasons, in some cases vigorously), or other Chromium salts have better economic factors, or, of course, both could be true or it could be something else entirely, perhaps even the unlikely case that the entire group of big-brand supplement manufacturers realized simultaneously that other salts featured better Chromium bioavailability or some similar health improvements and mutually decided the public was best served by changing their formulations practically overnight.
But somehow I find that last scenario improbable.
So what’s the truth? Does anyone know?
