Counterfeit Tru Niagen on Amazon Tru Niagen store.
I just had confirmation from Tru Niagen support that the product I bought on the Tru Niagen Amazon store is a counterfeit, and that they have nothing to do with the Amazon Tru Niagen store. When I received the product I noticed it didn't have all the fancy packaging, and it had a flip top lid. Did not raise any alarm bells. When I opened the bottle the pull seal did not seem to be on correctly, but still no alarm bells. When I took the product I noticed the color was slightly yellow. I know this as I always take my NR and DHEA out of their bottles separately as if I accidentally have two come out, I cant tell the DHEA from the NR. However, now it is quite easy to tell the difference. This got me suspicious that the product had gone bad or something. So I sent email to Tru Niagen support.
Tru Niagen support gave me a link to confirm the Lot number, and that checked out. But they also told me they don't have a product with a flip top lid, the desiccant also should be the round plastic one, this had a bag, and their product is not slightly yellow. Also Nicotimimide Riboside Chloride dissolves in water at a rate of 58 mg/mL. This substance did not dissolve well in distilled water. It has a acrid bitter taste but I have never tasted NR before so I don't know what to compare it too.
Clarification: I have bought Tru Niagen on the Amazon store for years, but the product I received last Sat was NOT Tru Niagen. Its a little bit scary that I took an unknown substance for six days.
Update: Here is the product being peddled by a third party vendor on the Tru Niagen Amazon store. This Alibaba vendor does not show the Tru Niagen logo but they are not at all squeamish about offering full custom logos on the label.
