Fatty15 Supplement

C15:0, an indispensable fatty acid crucial for overall health, becomes increasingly vital as you age. Fatty15 is a science-backed, patented, award-winning, pure and vegan-friendly C15:0 fatty acid supplement to support your long-term health and wellness.


Fatty15 enhances metabolic well-being, reinforces immune balance, and promotes heart health. Within six weeks of using this pentadecanoic acid supplement, two-thirds of customers report experiencing short-term benefits, such as improved mood, deeper sleep, or reduced snacking.

C15:0, or pentadecanoic acid, is an odd-chain saturated fatty acid found in minimal quantities in butter, certain whole-fat dairy products, and select fish and plants. A growing body of scientific evidence underscores the essential nature of C15:0 as a vital nutrient crucial for maintaining health. In the absence of sufficient C15:0 levels, sustaining an optimal state of health may prove challenging.

Evidence of C15:0 Health Benefits

To be classified as 'essential,' a nutrient must satisfy three specific criteria:

  1. Insufficient levels of the nutrient in the body lead to diminished health.
  2. The body does not produce an adequate amount of the nutrient on its own.
  3. The primary source of the nutrient is from either the diet or supplements.

Until recently, only two dietary fatty acids have met these criteria: alpha-linolenic acid (an omega-3 fatty acid) and linoleic acid (an omega-6 fatty acid). Now, let's examine how C15:0 aligns with these essential criteria.

Firstly, insufficient levels of C15:0 in the body are linked to suboptimal health. Numerous global population studies consistently reveal significant correlations between low circulating concentrations of C15:0 and compromised metabolic, immune, heart, and liver health. A comprehensive study involving over 14,000 individuals demonstrated that those with a lower intake of odd-chain fatty acids, including C15:0, in their diets faced an elevated mortality risk over 14 years.

While these studies underscore the associations between low C15:0 and diminished health, several peer-reviewed investigations have established C15:0 as the causal factor for promoting positive metabolic, immune, red blood cell, and liver health. Hence, mounting evidence supports the necessity of maintaining adequate levels of C15:0 in your body for overall well-being.

Lastly, your primary source of C15:0 is derived from your diet, specifically through whole-fat dairy products. C15:0 blood levels have traditionally served as an indicator of one's whole-fat dairy consumption, making it the most significant dietary contributor to C15:0. The challenge arises as conventional advice has discouraged the consumption of whole-fat dairy products for decades, resulting in a decline in population-wide C15:0 blood levels.

To safeguard your long-term health, Fatty15 offers a means to restore and sustain your C15:0 levels in a pure and vegan-friendly manner. This eliminates the need to revert to consuming calorie-rich whole-fat dairy products, which often contain higher levels of undesirable even-chain saturated fats, to attain your daily quota of C15:0.

Higher concentrations of C15:0 in the body have been associated with lower levels of anxiety and distress. This is likely due to the ability of C15:0 and its metabolite, pentadecanoylcarnitine (PDC), to cross the blood-brain barrier and exhibit targeted cell-based activities that support brain health, cognition, mood, and sleep quality. C15:0 has demonstrated anti-inflammatory properties, including the ability to reduce levels of IL-6 and MCP-1, which are associated with brain health. Moreover, the activation of PPARγ by C15:0 can further support cognition, mood, brain function, and sleep health. Additionally, the presence of higher circulating concentrations of PDC, a metabolite of C15:0, can stimulate various receptors such as CB1, CB2, 5-HT1A, and 5-HT1B, which are crucial for promoting brain health, cognition, mood regulation, and quality of sleep. Research studies have shown that individuals with elevated levels of C15:0 in their cerebral spinal fluid have a reduced risk of developing Alzheimer’s disease. This suggests a strong relationship between higher C15:0 concentration and improved brain health, cognitive function, mood stability, and overall well-being, which collectively contribute to lower levels of anxiety and distress.
