Which fits your priorities?
Only the points where these two differ, from the table above and each provider’s record.
Choose fatty15 if…
- Single-ingredient C15:0 supplement with a clear cell-membrane mechanism and published research behind it
- Strong brand recognition from high-profile longevity marketing
- C15:0 is hard to get from diet alone (mainly dairy fat), giving supplementation a defensible rationale
What to weigh up
- Pricing, ingredient panel, third-party lab testing, and longevity claims haven't been independently confirmed
- Whether C15:0 should be classified as an essential fatty acid is the company's own positioning, not settled consensus
Choose IM8 Health if…
- All-in-one daily blend reduces stack complexity vs. taking 5-10 separate supplements
- NSF Certified for Sport — independent third-party testing for banned-substance contamination and label accuracy
- Scientific advisory board includes Dr. James L. Green (former NASA Chief Scientist) and Dr. Dawn Mussallem (Mayo Clinic)
What to weigh up
- Newer brand (US launched December 2024) — long-term outcome data does not exist yet
- Not a weight-loss product — marketed as general wellness/longevity, not a metabolic-support therapy
