Intake of foods containing these VLSFAs or use of products containing them can contribute to higher levels. Increased intake of precursor fatty acids, or SNPs in the elongase enzyme, may alter levels.

The health implications of elevated VLSFAs levels are evolving, though they are generally found to be beneficial in health and aging. Several meta-analyses suggest a beneficial association of very long chained saturated fatty acids with cardiovascular health outcomes as well as lower risks of type 2 diabetes, atrial fibrillation, heart failure, and coronary disease. These VLSFAs may also be important in neural development and cognition. The mechanisms of these very long chained saturated fatty acids are not fully known. Because VLSFAs are components of ceremides involved in apoptosis, there is strong evidence that VLSFAs are protective against apoptosis and cell death.

Decreased dietary intake of these saturated fatty acids, or avoidance of products containing them, can result in low levels. Some VLSFAs can be synthesized from other fatty acids. Therefore, decreased levels of precursors, lack of vitamin and mineral cofactors, or SNPs in the elongase enzyme may also contribute to low levels. Specific deficiency in VLSFAs is not well studied. Though, due to their importance in brain development and their associations with improved health outcomes, as outlined above, research is evolving.

Behenic acid is a VLSFA which contains 22 carbons (22:0). Its name is derived from Ben oil (behen oil) from the Moringa oleifera tree. Commercially, products containing Moringa oil have high amounts of behenic acid in them such as hair conditioners, topical moisturizers, and other cosmetic oils. It can also be obtained through the diet in canola (rapeseed) oil and peanut oil. Using the elongase enzyme, it can be synthesized from arachidic acid.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
