Aging-Associated Amyloid-β Plaques and Neuroinflammation in Bottlenose Dolphins (Tursiops truncatus) and Novel Cognitive Health-Supporting Roles of Pentadecanoic Acid (C15:0)
Stephanie Venn-Watson, Eric D. Jensent
Published: 16 April 2025
There is an urgent need to identify interventions that broadly target aging-related cognitive decline and progression to Alzheimer’s disease (AD). Two new dose-dependent C15:0 activities (FAAH and MAO-B inhibition) have been found that can lower amyloid-β formation, lower neuroinflammation, and improve cognitive function in relevant animal models. These findings suggest that C15:0 may play a distinct role in supporting cognitive health.

Pentadecanoic Acid Supplementation in Young Adults with Overweight and Obesity: A Randomized Controlled Trial
Jeffrey B Schwimmer
Published: 26 July 2024
Daily C15:0 supplementation safely increased circulating C15:0 levels in young adults with overweight or obesity. Among participants who achieved C15:0 >5 μg/mL, clinically relevant improvements included lower liver enzymes (ALT and AST) and higher hemoglobin at 12 weeks.

The Cellular Stability Hypothesis: Evidence of Ferroptosis and Accelerated Aging-Associated Diseases as Newly Identified Nutritional Pentadecanoic Acid (C15:0) Deficiency Syndrome
Stephanie Venn-Watson
Published: 23 June 2024
Deficiencies in C15:0, an essential fatty acid, can cause fragile cells and a phenomenon called ferroptosis. In turn, ferroptosis accelerates aging and impacts our metabolic, liver, and heart health. This disease, called Cellular Fragility Syndrome, is the first nutritional deficiency syndrome discovered in 75 years. Fixing C15:0 deficiencies effectively strengthens cells, fights ferroptosis, slows cellular aging, and protects our long-term metabolic, liver, and heart health.

Effect of an Asian-adapted Mediterranean diet and pentadecanoic acid on fatty liver disease: The TANGO randomized controlled trial
The American Journal of Clinical Nutrition
Published: 29 November 2023
Above and beyond the benefits of a hypo-caloric diet, C15:0 supplementation in this randomized, controlled clinical trial effectively lowered LDL-cholesterol, lowered total fat mass, and caused beneficial shifts in the gut microbiome, including supporting Bifidobacterium adolescentis – a probiotic bacteria that supports longevity.

Stephanie Venn-Watson
Nicholas J. Schork
Published: 30 October 2023
This study, paired the ability of C15:0 to target longevity pathways, hallmarks of aging, and core components of type 2 diabetes, heart disease, cancer, and nonalcoholic fatty liver disease, support C15:0 as an essential nutrient with activities equivalent to, or surpassing, leading longevity-enhancing candidate compounds.

Pentadecanoic acid attenuates thioacetamide-induced liver fibrosis by modulating oxidative stress, inflammation, and ferroptosis pathways in rat
Mohammad Aabis, Priyanka Tiwari, et al.
Published: 01 May 2025
This study looked at a rodent model with liver lipid peroxidation, cell death, dysregulated iron metabolism and immune function and impaired liver function (Cellular Fragility Syndrome) and found that the C15:0 supplemented group had: healthier body weight, lower lipid peroxidation, lower RDW, higher hemoglobin, improved cell survival, restored healthy iron metabolism, lower proinflammatory cytokines and improved liver function.
