The Verdict
These two are essentially tied on our rubric - Thorne posts an 87 execution score and Life Extension an 87 on our 0-100 scale. On cost, Life Extension runs about $0.51 per dose versus Thorne's $0.72. Thorne's advantage is NSF Certified for Sport and ubiquinone form; Life Extension's is the Kaneka QH ubiquinol form, which may absorb better for older adults. In our view, if you are over 50 or want the reduced ubiquinol form, Life Extension is the pick and it costs less; if you need NSF Certified for Sport, Thorne is the choice. Both are high-quality.

Why This Comparison Matters
Thorne and Life Extension take different forms at the same 100mg CoQ10 dose. Thorne uses ubiquinone with NSF Certified for Sport testing; Life Extension uses ubiquinol (the reduced form, via Kaneka QH) which some research suggests absorbs better, particularly in older adults. This is the ubiquinone-versus-ubiquinol decision at the practitioner-grade tier.
Ubiquinol is the body's active, reduced form of CoQ10, and there is evidence it raises blood levels more efficiently for some people. Ubiquinone is cheaper, stable, and converts to ubiquinol in the body. Both are legitimate.
We scored both on evidence, quality, cost per dose, and transparency.
Detailed Score Breakdown
Thorne CoQ10 100mg
Thorne
100mg ubiquinone per capsule. At 100mg, one capsule is at the lower end of the clinical dose; statin users and those with cardiovascular disease will likely benefit more from 200mg (2 capsules) daily. Thorne sells this product for general wellness - statin users should consider their Ubiquinol product instead.
NSF Certified for Sport - the most rigorous third-party certification available, testing for 270+ substances banned in sport and verifying label accuracy. Thorne's manufacturing standards exceed cGMP requirements. Every batch is tested.
$0.72/day at 100mg (1 capsule); $1.43/day at 200mg (2 capsules), using Thorne's MSRP - the Amazon Buy Box has run higher (~$53) from third-party sellers. Highest cost per dose here, but NSF Certified for Sport is a meaningful premium for athletes and anyone who needs certification confidence.
Exemplary. Form (ubiquinone), dose, and all excipients clearly listed. NSF certification conspicuously displayed. Thorne publishes Certificates of Analysis on their website for most products.
NSF Certified for Sport makes this the go-to for competitive athletes and anyone who requires independent certification. The premium price is justified by the rigorous quality standard.
Life Extension Super Ubiquinol CoQ10 100mg
Life Extension
100mg ubiquinol (Kaneka QH) per softgel. Uses the branded Kaneka QH form of ubiquinol, which is the form used in the majority of published ubiquinol pharmacokinetic and clinical studies. At 100mg this hits the lower clinical dose; 200mg daily is well supported for statin users.
Life Extension third-party tests all products. ConsumerLab has reviewed Life Extension products and generally found good label accuracy. GMP certified facility. Uses Kaneka QH, a branded ingredient with strong quality documentation from its Japanese manufacturer.
$0.51/day at 100mg ubiquinol - a mid-premium price for the branded Kaneka QH form after a 2026 increase; the 60-count at $30.38 works out to $0.51/serving.
Excellent. 'Ubiquinol (as Kaneka QH)' is clearly stated. Softgel in oil base noted. Amount per serving listed. No proprietary blends.
Uses Kaneka QH, the branded ubiquinol form with the most published research support. Solid transparency and quality for the price.
How We Compared These Products
Every product in our database is scored on four equally-weighted pillars: dosing accuracy and form quality, purity verification (third-party testing), cost per clinically effective dose (not cost per pill), and label transparency. Each pillar is worth 25 points for a total of 100.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.
