Coenzyme Q10 and Ox Bile, a synergy.
Ox bile can increase the absorption of poorly bioavailable Coenzyme Q10 by improving its incorporation into bile-salt mixed micelles in the small intestine. This is a favorable absorption-enhancing interaction rather than a risk, and it is most relevant for people whose own bile production is reduced.

Synergy
What is happening. Ox bile can increase the absorption of poorly bioavailable Coenzyme Q10 by improving its incorporation into bile-salt mixed micelles in the small intestine. This is a favorable absorption-enhancing interaction rather than a risk, and it is most relevant for people whose own bile production is reduced.
Mechanism. Coenzyme Q10 (ubiquinone) is a highly lipophilic molecule with very low water solubility and notoriously poor, variable oral bioavailability. Before it can be absorbed across the enterocyte, it must be solubilized into mixed micelles, a process that depends on conjugated bile salts emulsifying the lipid and incorporating the CoQ10 isoprenoid tail into the micelle core. Ox bile supplies supplemental conjugated bile acids, so in people with low endogenous bile output (for example after cholecystectomy or with cholestasis/fat malabsorption) co-administering ox bile can improve micellization and therefore uptake of CoQ10.
Recommendation. If you have low bile output (post-gallbladder removal or known fat malabsorption) and take CoQ10, taking ox bile with the same fat-containing meal as your CoQ10 (ideally an oil-based or softgel CoQ10, 100 to 200 mg, with a meal containing some fat) is a reasonable way to support absorption. People with normal bile and gallbladder function generally do not need ox bile for this purpose; simply taking CoQ10 with a fatty meal is usually sufficient.
Minimum separation. Take together with a fat-containing meal (no separation needed; co-administration is the goal).
