Understanding Nervonic Acid: Normal vs Optimal Ranges

?What is Nervonic Acid?

Nervonic acid is a very long-chain monounsaturated omega-9 fatty acid (C24:1n9) found predominantly in brain white matter sphingomyelin and in small amounts in dietary sources like salmon, mustard seed oil, and hemp oil. It is important for myelination — the formation and maintenance of the myelin sheath surrounding nerve axons.

!Why It Matters

Nervonic acid is critical for brain development and myelin maintenance. Deficiency has been associated with multiple sclerosis-like demyelinating conditions, learning difficulties in children, and cognitive decline in the elderly. It has gained research interest as a neurological health marker and therapeutic target in demyelinating conditions.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Low nervonic acid: potentially linked to demyelination, cognitive impairment

How to Improve Your Levels

• 1Dietary sources: salmon, shark liver oil, mustard seed oil
• 2Nervonic acid supplements derived from hemp or mustard seed oil are available

When to Test

As part of advanced fatty acid profiling; neurological conditions assessment; multiple sclerosis research.
