🧬 A New Way to Think About Aging & Chronic Disease
Emerging research is shedding light on a process called ferroptosis—a form of cell damage driven by fragile cell membranes that are rich in polyunsaturated fats. The double bonds in the polyunsaturated fats are vulnerable to damage.
This then leads to lipid peroxidation, leading to cellular damage and contributing to conditions like:
– Type 2 diabetes
– Fatty liver disease
– Cardiovascular disease
– Elevated Ferritin
– Neurodegenerative disorders
One area of growing interest is the role of C15 (pentadecanoic acid), a healthy saturated fat that may help support cell membrane stability and reduce susceptibility to this type of damage. These levels are very influenced by diet. Full fat dairy is a great source of C15.
Low levels of C15 have been associated with poorer metabolic health and increased disease risk.
The Good News is you can test your C15 levels!
Genova Diagnostics offers testing.
At Mission Functional Medicine, we can order this test for our patients and pass along our discounted rate:
👉 $159 for patients
Non-patients can also order directly through Genova:
👉 A little over $200
đź’Š There is also a commercial product called Fatty15 that may help raise C15 levels if they are low.
If you have unexplained elevated ferritin (test negative for Hemochromatosis), or have NASH, prediabetes, or diabetes, consider checking your C15 levels.
