What Dr. Stephanie Venn-Watson, our co-founder and author of The Longevity Nutrient and over 80 peer-reviewed scientific publications, is reading.
This week, we’re excited to share our latest big science drop. As published in the peer-reviewed scientific journal Metabolites, we report the first nutritional deficiency syndrome to be discovered in 75 years. Let’s dive in.
What makes a deficiency, well, a deficiency?
Certain vitamins and minerals are so important that if we don’t get enough in our diet, we can develop a definable disease. Think: Vitamin C deficiency and scurvy, or Vitamin D deficiency and rickets. In fact, a key proof point of any nutrient deemed as “essential” should have evidence of disease in the absence (or too-low levels) of that nutrient. In turn, that disease should be readily fixed when appropriate nutrient levels are restored. This is the hallmark of a nutritional deficiency.
This is where C15:0 comes in.
As published in Scientific Reports back in 2020, we demonstrated how C15:0 meets the criteria of an essential fatty acid, including the following:
As would be expected of C15:0’s essential role in maintaining our long-term health, the past 12 years of studies have culminated in our discovery of Cellular Fragility Syndrome, a C15:0 deficiency syndrome.
What is Cellular Fragility Syndrome?
During 2012, a team of researchers at Columbia University discovered a new type of cell death, called ferroptosis. Since then, over 10,000 papers have been published on ferroptosis. Here’s how ferroptosis kills our cells:
Yikes. Ferroptosis accelerates our aging and speeds up the onset and severity of metabolic, heart, and liver conditions. Despite all this science, how and why ferroptosis showed up had remained unknown. Until now, that is…
In our paper, we demonstrate how too-low C15:0 in our diets and cell membranes cause ferroptosis, including creating fragile cells, unwanted intracellular iron, advanced cellular aging and the resulting chronic conditions. This C15:0 deficiency cascade is called Cellular Fragility Syndrome, and it may be affecting as many as 1 in 3 of us.
How do I know if I have Cellular Fragility Syndrome?
While Cellular Fragility Syndrome can result in general fatigue and other ails often attributed to “getting older”, it is best detected using blood tests.
First and foremost, Cellular Deficiency Syndrome can be detected by measuring your C15:0 blood levels (preferably red blood cell membrane levels). As described in our Metabolites paper:
Just as importantly, however, is detection of clinically relevant blood changes expected with Cellular Fragility Syndrome, which may include any combination of the following:
It is important that you work with your physician to assess and interpret these indices.
How much C15:0 do I need to maintain healthy levels?
Globally, most people have C15:0 levels around 0.2% of total fatty acids, which puts us right at the breaking point of deficient vs. healthy. This consistent level also means that either our bodies are churning enough low level C15:0 to support 0.2% or that we reliably get trace amounts of C15:0 in our diets to achieve 0.2%.
So how do we get ourselves from 0.2% to a more secure spot in the healthy zone?
Here’s a good rule of thumb: every 100 mg of added C15:0 increases most people’s C15:0 levels by 0.1%. This means that most of us (who have 0.2% C15:0) need between 100 to 200 mg of added C15:0 a day to achieve and maintain healthy levels of 0.3% to 0.4%.
While whole-fat dairy products contain C15:0, we have previously covered how dairy fat contains only 1% C15:0 and > 40% proinflammatory even-chain saturated fatty acids. This unfair advantage of proinflammatory fats in foods is why Thorning et al. concluded that simply eating more dairy fat does not reliably improve our metabolic, heart, and liver health.
In fact, Thorning et al. concluded that individual beneficial nutrients in dairy fat (ahem, C15:0) perform best in isolation versus in the milieu of dairy fat.
This also explains why we spent years developing a pure C15:0 ingredient that:
