THE TEACHING CONNECTION

Different families of fatty acids. They do not all have the same dietary requirements or biological roles.

What it does

Different families of fatty acids. They do not all have the same dietary requirements or biological roles.

How supplementation is approached

Treat omega families as distinct fats rather than a single deficiency. Dr. Purser’s membrane approach reviews the dietary pattern and exact fatty-acid findings before selecting additional support. An omega-3 product is not automatically a replacement for every other fatty acid.

What symptoms can—and cannot—tell you

Essential fatty-acid deficiency is uncommon but can affect skin and other tissues. ALA (omega-3) and linoleic acid (omega-6) must come from the diet. Symptoms or an individual fatty-acid measurement do not by themselves select a supplement.

Food sources

Nuts, seeds, plant oils, avocados and other foods supply different fatty acids.

Supplement forms

Linoleic acid is an essential omega-6 fat. Omega-7 and omega-9 are not separate essential dietary requirements.

What to track and reassess

Document the specific fat or preparation recommended and the reason for it. Review the total diet before stacking several oil products.

From starting support to follow-up

If you and your clinician start a CMA replenishment plan, you may add one new product at a time, often waiting 3–7 days to see how you feel. A check-in is usually planned near ten weeks during an approximately 100-day period. Follow your written plan for amounts and timing. At follow-up, you may continue, change, or stop each item. This timetable does not automatically end longer-term support.
