There is an urgent need to identify interventions that broadly target aging-related cognitive decline and progression to Alzheimer’s disease (AD). Bottlenose dolphins (Tursiops truncatus) have histologic changes similar to AD in humans, and they also develop shared age-associated co-morbidities identified as risk factors for AD in humans, including type 2 diabetes, ferroptosis, and iron overload, which can be driven by nutritional C15:0 deficiency. We hypothesized that (1) dolphins would have amyloid beta (Aβ) plaques and neuroinflammation that paralleled that of humans in relation to age-related progression, quantitative concentration, and brain region; and (2) C15:0 would have dose-dependent activities relevant to protecting cognitive health. Quantitative immunohistochemistry staining was used to assess 68 tissues from archived brains of 19 Navy dolphins to evaluate associations among amyloid beta (Aβ) plaques and neuroinflammation by brain region, sex, and age group. Further, dose-dependent C15:0 activities, using a third-party panel intended to screen for potential AD therapeutics, were evaluated. Similar to humans, dolphins had the highest Aβ plaque density variation in the hippocampus (90th percentile of 4.95 plaques/mm2), where plaque density increased with age (p = 0.05). All measured markers of neuroinflammation were detected, including the highest concentrations of activated microglia (CD68+) in the hippocampus (0.46 ± 0.38 cells/mm2). C15:0 was a dose-dependent inhibitor of two targets, fatty acid amide hydrolase (FAAH) (IC50 2.5 µM, 89% maximum inhibition at 50 µM relative to URB597) and monoamine oxidase B (MAO-B) (IC50 19.4 µM, 70% maximum inhibition at 50 µM relative to R(-)-Deprenyl). These activities have demonstrated efficacy against Aβ formation and neuroinflammation, including protection of cognitive function in the hippocampus. These findings suggest that, in addition to protecting against AD co-morbidities, C15:0 may play a distinct role in supporting cognitive health, especially at higher concentrations.

A big paper was just published on a newly discovered nutritional C15:0 deficiency syndrome, called Cellular Fragility Syndrome. This is a big deal because nutritional deficiency syndromes (like vitamin C deficiency and scurvy, or vitamin D deficiency and rickets) are rarely discovered. This latest paper describes how d

Years ago, while helping to continually improve the health and welfare of aging Navy dolphins, our fatty15 founders discovered C15:0 (aka pentadecanoic acid) as the first essential fatty acid to be identified since omega-3, which was over 90 years ago.

Pentadecanoic acid (15:0), a saturated fatty acid, associated with improved insulin sensitivity. You find it in dairy, fats and oil, lamb, veal, and game, beef products.

Pentadecanoic acid (C15:0) is an essential odd-chain saturated fatty acid with broad activities relevant to protecting cardiometabolic, immune, and liver health. C15:0 activates AMPK and inhibits mTOR, both of which are core components of the human ...
