Best CoQ10 Supplements 2026: Cost per Effective Dose
200 mg of CoQ10 costs $0.30 to $1.70 across the 10 we score ($0.30 to $1.25 for the 7 shown below), at each brand’s list price. The cheapest are standard CoQ10 capsules; ubiquinol costs 1.1 to 2.2 times as much per 200 mg as the standard CoQ10 products we score ($0.67 vs $0.30 to $0.62). Only 1 of the 10 we score is on a public testing list (USP Verified: an outside group checks the ingredients, potency and how it’s made): Nature Made CoQ10 200 mg, which costs more than the cheapest.

1 of the 10 is on a public testing list (USP Verified). We also price Doctor's Best High Absorption CoQ10 with BioPerine 200 mg and Qunol Ultra CoQ10 100 mg; Doctor’s Best 100 mg softgels, in the table, give the same CoQ10 for about the same cost or less. We also price 1 more ubiquinol, which costs more per 200 mg than any shown. To choose by need, see the best CoQ10, scored.
Is ubiquinol worth the extra cost?
In our view, probably not for most people. Ubiquinol costs 1.1 to 2.2 times as much per 200 mg as the standard CoQ10 products we score ($0.67 vs $0.30 to $0.62). The studies on whether it absorbs better disagree, and no trial shows better health results. See ubiquinol vs ubiquinone for the studies.
Per 200 mg, or per serving?
Per serving is what you pay each day for one softgel. Per 200 mg is fairer when strengths differ: a 100 mg softgel gives half the CoQ10 of a 200 mg one. The heart-failure and migraine trials used 300 mg a day. See how much CoQ10 to take.
Amazon’s price can differ from the list prices here.
Not scored: Puritan’s Pride CoQ10 200 mg. Puritan's Pride's store blocked our reads and no other store we use sells it, so we have no list price to compare. 200 mg of CoQ10 a softgel; no third-party testing claim on the label.
Not scored: Kirkland Signature CoQ10 300 mg. It is on USP Verified, but Costco lists it as unavailable, so we could not confirm a price and do not score it.
