The Verdict
Life Extension (A- overall) slightly outscores NOW Foods (B+ overall) with better quality documentation and enhanced bioavailability technology in its formulation. NOW Foods wins on value with a lower cost per day. Both use the same Kaneka Ubiquinol active ingredient. For most buyers, NOW Foods is the smarter value play. Life Extension makes sense if you want the enhanced absorption technology and trust their formulation science.

Why This Comparison Matters
Both Life Extension and NOW Foods offer ubiquinol - the reduced, active form of CoQ10 that the body can use directly without conversion. This is important because as people age (especially over 40), the body becomes less efficient at converting ubiquinone to ubiquinol. Both products use Kaneka Ubiquinol, the most researched branded ubiquinol ingredient.
Since both use the same branded active ingredient at the same dose, this comparison is really about the surrounding formulation, third-party testing, and cost per effective dose.
We scored both on our standard rubric.
Detailed Score Breakdown
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.
$0.37/day at 100mg ubiquinol - reasonable for the ubiquinol form with a branded Kaneka ingredient. Buying a 60-count bottle costs more per serving; the 60-count at $22 is $0.37/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.
NOW Foods Ubiquinol 100mg
NOW Foods
100mg ubiquinol per softgel. Ubiquinol form means no conversion step required, making this appropriate for adults over 40. 100mg is at the lower clinical dose; 200mg is more commonly studied for statin users.
NPA GMP audited facility. NOW Foods tests all products internally. No IFOS, NSF, or USP third-party certification. ConsumerLab has reviewed NOW CoQ10 products in the past and found label accuracy acceptable.
$0.25/day at 100mg ubiquinol - very competitive pricing for the ubiquinol form. Buying the 120-count bottle significantly lowers per-capsule cost.
Clearly states 'Ubiquinol' and the Kaneka QH source on the label. Oil base (in organic rice bran oil) disclosed. All excipients listed.
Best value ubiquinol option with Kaneka QH sourcing. A 120-count bottle is the sweet spot for cost per dose. Lacks a top-tier third-party cert but NOW's track record is solid.
How We Compared These Products
Every product in our database is scored on four equally-weighted categories: clinical evidence quality, third-party testing and purity verification, cost per clinically effective dose (not cost per pill), and label transparency. These scores combine into an overall letter grade from A+ through F.
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.
