I was a regular customer buying True Niagen on Amazon Spain. Last purchase, I got the product box with the seal cut, the bottle inside was evidently opened before. Contacted Amazon and Tru Niagen. they wanted me to send back that. I am not sending a supplement back to be reselled by them. I got no money back, they did not offer me a new sealed product. I do not trust in this company and do not recommend it at all!

They make it very hard to cancel the subscription. I did not really see an improvement in anyway after 8 months of taking it.
