As explained in the "Synthetic vs. Natural" section of the CoQ10 and Ubiquinol Supplements Review, naturally formed CoQ10 is 100% in the "trans" isomer form. Synthetically formed material is also predominantly in the "trans" form with a small amount in the "cis" form. Since the fermentation process using bacteria or yeast is much cheaper than chemical synthesis and provides 100% natural (trans) CoQ10, most, but not all, CoQ10 found in the marketplace today is made by a fermentation process.

The "Natural Fermentation Process" also produces Co-Q9, 8, 7 etc.. which then has to be removed by another process. The synthetic process only produces Co-Q10.
Three Japanese companies produce Co-Q10 via the fermentation process; Kaneka, Mitsubishi and Asahi. A fourth Japanese company, Nishin extracts a compound called "Solanesol" from tobacco leaves and converts it to Co-Q10.
