My Reviews

Great price for a needed supplement

Posted by Reviewer1625695 on Sep 24, 2009

I landed on this product from Steve Gibson's excellent Vitamin D analysis page and just bought this based on his recommendation. So far, so good. I can definitely tell a difference in my overall health. I just feel better. I've noticed the biggest difference in my sleep. I've been sleeping much, much better since getting my Vitamin D level up.

absorption seems low

Posted by Reviewer1625695 on Jun 16, 2014

I am by no means an expert on Vitamin C, but the absorption rate of this powder seems very low. I switched to it from a different brand with almost exactly the same ingredient breakdown. That other product produced noticeable G.I. activity within an hour or so, which is what you would expect with a large dose of Vitamin C being rapidly absorbed in the intestines on an empty stomach. This product, however, does not produce any noticeable G.I. response. My urine also seemed more pungent and quite a big more vibrant in color than usual, which tells me that a lot of the Vitamin C is not being absorbed and is simply leaving my system. It's also not nearly as effervescent as the other product is. It barely fizzes at all, whereas the other one fizzes like a soft drink. I've switched back to the other product for now. I wish I knew more of what was going on, because just going by labels this should be virtually identical. I'm going to keep looking and see if I can nail down the differences.
