The proportion of ALA, a plant omega-3 fatty acid, in your red blood cells.
ALA, or alpha-linolenic acid, is the plant-based omega-3 fatty acid found in foods like flaxseed, walnuts, chia, and rapeseed oil. It is an essential fat, meaning your body cannot make it and must get it from food. This test reports how much ALA sits in your red blood cell membranes, as a percentage of all fatty acids there.
Your body can convert a small amount of ALA into the longer-chain omega-3s EPA and DHA, though this conversion is limited.
ALA reflects your intake of plant omega-3 sources. Because the body converts only a small fraction of ALA into EPA and DHA, a good ALA level does not guarantee a high Omega-3 Index. This is useful to know for people who rely on plant foods rather than fish.
Seeing ALA separately helps explain your omega-3 picture, especially in vegetarian and vegan diets.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
There is no single official cut-off for ALA in red blood cells. ALA usually makes up only a small percentage of red blood cell fatty acids, even with good plant omega-3 intake, because it is used and converted in the body. Ranges depend on the lab and method, and ALA is interpreted alongside the Omega-3 Index.
You learn your plant-based omega-3 status and how it relates to your longer-chain EPA and DHA levels. This helps tailor advice on flax, walnuts, algae oil, or fish within a personalized action plan, especially on plant-based diets.
Recent changes in diet take weeks to show in the membrane value. Conversion of ALA to EPA and DHA is limited and varies between people. Methods differ between labs, so compare results from the same assay.
Best read alongside the Omega-3 Index, EPA percentage, and DHA percentage.
