Omega-3 polyunsaturated fatty acids (n-3 PUFAs) have been linked to healthy aging throughout our lifespan - from fetal development to prevention of Alzheimer’s disease. Omega-3 fatty acids are anti-inflammatory and used in cell membrane production, function, and overall gene expression. Most standard American diets are deficient in common n-3 food sources such as flax, oily fish, nuts, and green leafy vegetables. Deficiencies in n-3 have been correlated with many clinical conditions such as neurodevelopmental and behavioral disorders, cardiovascular disease, cognitive decline, mood disorders, skin abnormalities, visual changes, and cancer.

What does it mean if your Total w3 result is too low?

The reference ranges for omega-3 fatty acids are onetailed since their health benefits are well-studied and deficiencies are associated with many clinical conditions. Low levels can be seen with decreased dietary intake of n-3 containing foods. Gastrointestinal malabsorption or maldigestion should also be considered. Additionally, desaturase and elongase enzymes are used to metabolize and create n-3 fatty acids from the essential alpha-linolenic acid. Lack of vitamin or mineral cofactors for these enzymes, or single nucleotide polymorphisms (SNPs) can contribute to lower, or sometimes higher levels of each. Nutrients such as zinc, vitamin B6, vitamin B3, and magnesium are important cofactors for fatty acid metabolism. Other enzymatic influences such as alcohol, cortisol, and adrenocorticoids can also influence these enzymes. It should also be noted that there is competition between the omega-3 and omega-6 fatty acids for use of the desaturase and elongase enzymes which may alter levels of fatty acid metabolites.

What Healthmatters Members Are Saying

5 stars rating

I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with  any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
