Fatty15 vs Timeline (Urolithin A / Mitopure): Two Different Longevity Bets
Fatty15 and Timeline’s Mitopure (urolithin A) are both premium “healthy aging” supplements that show up in the same conversations, so people naturally compare them. But like most of these matchups, they target different biology. Fatty15 delivers C15:0 for cell-membrane and metabolic health; Mitopure delivers urolithin A to support mitochondrial quality (specifically a process called mitophagy). Here’s how to choose.
The Core Difference
Mitopure (urolithin A) is researched primarily for mitochondrial health and muscle function, it’s thought to support “mitophagy,” the cellular clean-up of damaged mitochondria. Fatty15 (C15:0) is researched for cell-membrane stability and metabolic/liver markers. Different targets, different mechanisms.
Fatty15 vs Mitopure: Side-by-Side
| Fatty15 (C15:0) | Timeline Mitopure (Urolithin A) | |
|---|---|---|
| Key ingredient | Pentadecanoic acid | Urolithin A |
| Primary focus | Cell membranes, metabolic/liver | Mitochondria, muscle function |
| Notable research | Membrane stability, metabolic markers | Muscle strength/endurance trials |
| Source | Plant-based fatty acid | Derived from ellagitannins (e.g., pomegranate) |
| Price tier | Premium | Premium |
Which Longevity Supplement Should You Pick?
- Choose Fatty15 (C15:0) if you’re interested in cell-membrane, metabolic, and liver health, and the “essential fatty acid” research.
- Choose Mitopure (urolithin A) if your priority is mitochondrial support and muscle/physical function, which has some of the more notable human trial data in the space.
- Both is possible, they don’t overlap, but both are premium-priced, so most people start with the one that matches their main goal.
If you lean toward C15:0, remember you can get the molecule affordably via a generic pentadecanoic acid supplement rather than the branded product, our Fatty15 review covers that trade-off.
Frequently Asked Questions
Is Fatty15 or Mitopure better?
Neither is universally “better”, they target different systems. Mitopure (urolithin A) focuses on mitochondria and muscle; Fatty15 (C15:0) focuses on cell membranes and metabolic health. Pick based on your goal.
Can I take Fatty15 and urolithin A together?
There’s no known interaction, and they address different aspects of aging (membranes vs mitochondria), so taking both is reasonable, budget permitting.
Fatty15 vs Timeline for longevity, which has better evidence?
Urolithin A (Mitopure) has some notable human trials on muscle function; C15:0 (Fatty15) has promising but earlier, often preclinical or observational data. Different strengths, different targets.
Do they do the same thing?
No. Fatty15 supports cell-membrane and metabolic health; Mitopure supports mitochondrial quality. They’re complementary, not interchangeable.
