Some studies have found that the delivery system-i.e. powder form vs oil/lipid delivery systems--is the single most important factor in determining the bioavailabilty of CoQ10.
Some of the cheaper supplements may use the powdered form of ubiquinone in capsules, but the more expensive brands use liquid/soft gel capsules which deliver the ubiquinone with an oil/lipid.
Soft-gel capsules with CoQ10 in oil suspension
A successful approach was to use the emulsion system to facilitate absorption from the gastrointestinal tract and to improve bioavailability. Emulsions of soybean oil (lipid microspheres) could be stabilised very effectively by lecithin and were utilised in the preparation of soft gelatine capsules. In one of the first such attempts, Ozawa et al. performed a pharmacokinetic study on beagle dogs in which the emulsion of CoQ10 in soybean oil was investigated; about two times higher plasma CoQ10 level than that of the control tablet preparation was determined during administration of a lipid microsphere. Although an almost negligible improvement of bioavailability was observed by Kommuru et al. with oil-based soft-gel capsules in a later study on dogs, the significantly increased bioavailability of CoQ10 was confirmed for several oil-based formulations in most other studies.
There really isn't much difference, if any, in cost between the ubquinol type Boomer bought and the soft/liquid gel capsules of ubiquinone the other major manufacturers of supplements, like Nature Made which I've used, have on the market. The big savings, for me, is when I buy them during a BOGO sale--I save about $36 a bottle.
So, I wouldn't bother with ubiquinone supplements in powdered form, but, beyond that, I'm not convinced that there is a significant difference in bioavailability between ubiquinol and ubiquinone which is in an oil/lipid based capsule. There is a tremendous amount of manufacturer's hype about ubiquinol that doesn't seem fully supported by research on humans.
But, if one wants ubiquinol, careful shopping can find it at much lower cost--at places like Amazon-- than the product Boomer bought.
This one, for instance, NutriGold CoQ10, 100mg, 120 Softgels - High Absorption CoQ10 GOLD with Kaneka Q10 is only $16.95--and that would be equivalent to the liquid Boomer bought--same strength, same 2 month supply. And the manufacture makes the same claims for the superiority of this product as the one Boomer bought.
For general health, one can always try increasing one's dietary intake of ubiquinone--some foods are much higher in it than others.
