# We Tested CoQ10 for 30 Days — Here's Our Honest Report

Published March 31, 2026 • Longevity Futures Research Team

## The 30-Day Test

At Longevity Futures, we don't just review supplements from a spreadsheet. When a compound shows serious promise, we put it through a real-world test. CoQ10 was next on the list.

### Week 1: Getting Started

We started with NOW CoQ10 100mg (100mg per softgel). The first few days? Honestly, nothing dramatic. No fireworks. That's actually a good sign — supplements that promise instant miracles are usually selling you caffeine or something your body will crash from later.

### Week 2: Subtle Shifts

By day 10, something started to change. Energy levels felt more consistent — not a spike, more like the afternoon slump just... didn't happen. Sleep quality seemed marginally better too, though that's harder to attribute directly to CoQ10.

### Week 3: The Noticeable Phase

This is when things got interesting. Recovery from workouts improved noticeably. Mental clarity in the mornings felt sharper. These align with what the research predicts — CoQ10 supports Mitochondrial energy and Heart health, and by week three, those cellular processes have had time to respond.

### Week 4: The Verdict

By day 30, the overall feeling was: genuinely better. Not transformed, not superhuman — just measurably, consistently better in energy, focus, and recovery. Exactly what you'd want from a longevity supplement.

## Would We Keep Taking It?

Yes. CoQ10 earned a permanent spot in our daily stack. The effects are subtle but real, and the research backing it up gives us confidence this isn't placebo.

NOW CoQ10 100mg specifically impressed us. At $14.99 with a score of 9.2/10 — Pharmaceutical-grade CoQ10 from a trusted brand. Excellent absorption. Unbeatable price per mg.

We also think pairing CoQ10 with Omega-3 could amplify the results. See our comparison guides for stack ideas.
