Pruvit has launched some pretty unique products in the past year. One of them is Keto//OS NAT which they "claim" that its ketone salts are created through a "fermented process".
Now I have spoked to a lot of companies that import and distribute BHB salts and NONE of them are familiar with "fermented BHB salts".
In fact, I heard that they might have been tested to see if any live cultures existed. If these were fermented then live cultures would show up during an analysis. They found that NAT contained no live cultures. So, for me, the hunt for these elusive "fermented ketones" continues.
Apart from that this keto supplement contains an unspecified dosage of R-BBHB aka D-BHB. This is the bioidentical form of BHB, which are the same form that are NATurally produced by the body. These are the "new generation" of BHB that are being used in the top-rated ketone supplements this year. In fact it is used in Ketond BioMAX which is this year's #1 rated keto supplement.
