Dose check · CoQ10
Does one serving reach the studied CoQ10 dose?
The research on CoQ10 uses 100 mg to 300 mg (general maintenance 100-200mg/day; higher doses of 300mg/day have also been studied). Every one of the 5 products here reaches the low end in a single serving, so one serving a day covers the studied dose.
The label trap on CoQ10: ubiquinol absorbs ~1.5-2x higher plasma than ubiquinone at the same mg — real but modest, not the dramatic advantage marketed; no outcome trial shows ubiquinol works better
Method: studied range from our own CoQ10 dosage guide (PMID 25282031), checked against the 5 products above that state a dose — capsules in whole servings, powders in fractions. Trial doses, not a prescription.
The shelf · CoQ10
The CoQ10 shelf is unusually consistent
Across 5 products from 5 brands, the cheapest day is Doctor's Best High Absorption CoQ10 200mg with BioPerine at $0.32 and the priciest is Jarrow Formulas QH-Absorb Ubiquinol 100mg at $1.12, a gap of 3.5×. With prices this close, which of these CoQ10 products has been independently checked matters more than the price.
Method: the 5 CoQ10 products above, compared on label facts, serving size, servings per container, form, price. Not a dosing recommendation.
How these 5 CoQ10 products were ranked
Not one of these 5 CoQ10 products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever CoQ10 you buy. Full methodology.
