Nestle sold the same Mitopure in its Celltrient line. They moved this line to Solgar, which Nestle also now owns. They may have other sales on it.
I first bought the Celltrient at a great discount on Ebay, as some sellers were selling stock with an expiration date only a few months away. I got these for around $25-$30 a month.
Time Line Nutrition has a deal with Truemed that will allow their doctors to prescribe Urolithin A to you. This is free and only requires describing test results or a prior doctor's evaluation of your health. I, too, got this done, in December.
The original Urolithin A available is Mitopure. It's made in Europe. Other manufacturers of Urolithin A now seem to exist, but the items I saw on Amazon a year or two ago looked hokey. It could be different, today.
