A very long time to receive the products I chose Biotivia because it shipped from UE, so the delivery was, in the past, very fast and with no custom problems. Npw Biotivia ships from wherever is suitable for them, most often from the USA. My last order took more than 2 months, almost 3, to be delivered. The package was stuckat the custom and I had to pay a surplus of almost 100 euros. With these conditions, I am not going to use Biotivia anymore.

No Follow up on use of MitoTrans. I called Biotivia before ordering mostly to ask questions about the delivery. I was curious why the shipping was $47. I was told it was temperature sensitive. I go the impression I was was going to be an early adopter of a new product offering in 2014 of NAD+ sold as MitoTrans. I ordered 2 months months supply for a total of $1000. Not a cheap price for me but I wanted to try it. I Did receive the package promptly. It came in a foam box with ice pack. The printed material that came with the order was very unprofessional and unimpressive. It looked like research notes. I followed the directions for using it and It didn't work. I didn't feel any better. I then Found the same product sold by other vendors for less than 50 dollars without the fancy packaging. I felt duped. No one at Biotivia ever asked me for customer feed back.

Been trying to cancel this subscription… Been trying to cancel this subscription for supplements for approx 6 months. Nobody from the company will return phone call or return emails regarding cancellation process!

Feedback I like your products, especially the Resveratrol, I stopped buying because the price increase or the lack of offers related to my favourite products, plus I found your site too commercial nowadays Thanks

The product is great but haven't… The product is great but haven't received a shipment since June or July 2020 and no communication as to why
