Fatty15 Ingredients: What’s Actually Inside the Capsule?
Part of Fatty15’s appeal is its simplicity, it’s built around a single active ingredient rather than a long proprietary blend. That transparency is a genuine plus. Here’s exactly what’s in Fatty15, what the active ingredient does, and how to read the label so you know what you’re paying for.
The Active Ingredient: FA15 (Pure C15:0)
Fatty15’s active ingredient is FA15, the brand’s patented, 100% plant-based form of pentadecanoic acid (C15:0). C15:0 is an odd-chain saturated fatty acid found naturally in trace amounts in whole-fat dairy and some fish. Fatty15 delivers it in a pure, standardized, free-fatty-acid form so each dose is consistent.
Is Fatty15 Vegan and Clean?
Yes, the FA15 ingredient is plant-derived and vegan, not sourced from fish or dairy. Fatty15 markets itself as free of common additives, and the single-active-ingredient design means there’s no long list of fillers or proprietary blends to decode. The gummy version will include additional ingredients (for the gummy base and flavor) versus the capsule.
What C15:0 Does in the Body
Once absorbed, C15:0 is incorporated into cell membranes, where research suggests it supports membrane stability and reduces oxidative damage, and it has been associated with favorable metabolic and liver markers. It’s the same molecule regardless of brand; FA15 is simply Fatty15’s specific, tested form of it.
How to Read a C15:0 Label
- Active ingredient: confirm it lists pentadecanoic acid / C15:0 (not a vague “odd-chain blend”).
- Dose per serving: check the milligrams of C15:0 per capsule.
- Testing: look for third-party testing or a certificate of analysis.
- Fillers: fewer is better; a clean single-ingredient formula is ideal.
Same Ingredient, Cheaper Options
Because the active ingredient is simply C15:0, generic pentadecanoic acid supplements contain the same molecule, often at a lower price. The differences are the patented FA15 form and testing. Our Fatty15 review weighs whether the branded version’s extras are worth it for you.
