C15 (pentadecanoic acid) strengthens cells to support healthy aging.
"active ingredient, C15, that strengthens your cells to support healthy aging. Don't take my word for it; look at the science." (said at 1:01:44)
While published in vitro and preclinical research suggests that pentadecanoic acid (C15:0) incorporates into lipid membranes, enhances membrane stability, inhibits ferroptosis, and shares cell-signaling pathways (such as AMPK activation and mTOR inhibition) with longevity-associated compounds, these findings stem primarily from cell-culture phenotyping assays, animal models, and theoretical reviews (the 'Cellular Stability Hypothesis'). Robust clinical trial evidence demonstrating that C15:0 supplementation strengthens human cells to promote healthy aging in humans is currently lacking, making the claim overstated.

"To assess the potential for C15:0 to enhance processes associated with longevity and healthspan, we used human cell-based molecular phenotyping assays to compare C15:0 with three longevity-enhancing candidates: acarbose, metformin, and rapamycin." (abstract, results, passage verified)

"Pentadecanoic acid (C15:0), an odd-chain saturated fat, is an essential fatty acid with the primary roles of stabilizing cell membranes and repairing mitochondrial function. By doing so, C15:0 reverses the underpinnings of ferroptosis. Under the proposed "Cellular Stability Hypothesis", evidence is provided to show that cell membranes optimally need >0.4% to 0.64% C15:0 to support long-term health and longevity."
