✓ Also buy if…- You're already on Life Extension's curated longevity protocols — brand consistency matters
- You want the strongest patent-grade chain-of-custody (Kaneka + PrimaVie + LE QC stacked)
✗ Also skip if…- You're under 40, healthy, no statin — go Doctor's Best (#3) ubiquinone at $15/month
Life Extension Super Ubiquinol CoQ10 with PrimaVie Shilajit is a licensed-Kaneka-QH bottle with an unproven absorption carrier stacked on top. We used to call it the highest-plasma-Q10 bottle on the market; the study that claim rested on does not exist, so we no longer say it. The formulation stacks two patent-grade ingredients in one softgel: 100 mg licensed Kaneka QH ubiquinol (the reduced form with 2-4× bioavailability advantage over ubiquinone in adults 40+) plus 100 mg PrimaVie shilajit, whose additional absorption gain is claimed by its manufacturer and supported by no published pharmacokinetic trial — we previously printed a 29-39% figure here and have retracted it.
At $45 for 60 softgels at 1/day, it's the most expensive ubiquinol per active mg on the list, and the part of that price you can actually verify is the Kaneka QH form, not the carrier. What the licensed form itself buys is higher plasma Q10 than any single bottle achievable without the shilajit carrier. Eight weeks running 1 softgel with dinner, here's the full breakdown.
