Omega-3 Deficiency

Assess whether you present clinical signs of omega-3 deficiency.

Omega-3 fatty acids (EPA and DHA) are essential fatty acids that the body cannot manufacture. They play a fundamental role in regulating inflammation, brain function, and mood balance. Modern diet, too rich in omega-6 and poor in fatty fish, creates an imbalance in the omega-6/omega-3 ratio that promotes chronic inflammation and cognitive disorders.

Points forts

+ Rapid identification of clinical signs
+ Simple self-assessment test
+ Detection of cognitive and behavioral disorders related to EPA/DHA deficiency

Limites

- Does not replace blood testing
- Some signs may have other causes
- Limited sensitivity for subclinical deficiencies

Maintenir votre équilibre

Consume small fatty fish

Prioritize sardines, mackerel, and anchovies two to three times per week. These small fish accumulate fewer heavy metals than large predators and provide an excellent naturally balanced EPA/DHA ratio.

Use omega-3 oils as dressing

Alternate between canola oil (9.1 g/100g of ALA), walnut oil, and camelina oil as raw dressing. Never heat them as omega-3 fatty acids are very sensitive to thermal oxidation. Keep them refrigerated.

Limit excessive sources of omega-6

Reduce sunflower, corn, and soy oils in your daily cooking. These oils unbalance the omega-6/omega-3 ratio and promote pro-inflammatory prostaglandin production via arachidonic acid.

Votre protocole naturel

Request an erythrocyte fatty acid profile

This test measures the omega-3 index (EPA+DHA in red blood cells, optimal above 8%) and the AA/EPA ratio (optimal below 3:1). It reflects your status over the last two to three months, much more reliable than a single plasma measurement.

Supplement with EPA and DHA

Take 1 to 2 g of EPA+DHA daily in triglyceride form (better absorption than ethyl esters). Choose a product with a TOTOX index below 26 to guarantee freshness and absence of fatty acid oxidation.

Increase frequency of fatty fish

Move to three to four servings of small fatty fish per week: sardines (2.0 g/100g), mackerel (2.7 g/100g), anchovies (1.5 g/100g). Prioritize gentle cooking methods (steaming, papillote) to preserve omega-3 from thermal oxidation.

Rebalance the omega-6/omega-3 ratio

Replace sunflower oil with canola or olive oil in cooking. Reduce consumption of ultra-processed products, rich in hidden omega-6 oils, and increase nuts, ground flax seeds, and chia seeds.

Flax and chia seeds daily

Add a tablespoon of ground flax seeds (23 g of ALA/100g) or chia seeds (18 g/100g) to your smoothies or yogurt. Vegetable ALA converts poorly to EPA and DHA (5 to 10%) but contributes to overall ratio balance.

Perilla oil as vegetable alternative

Perilla oil (Perilla frutescens) is the most concentrated vegetable source of alpha-linolenic acid (ALA, approximately 60%). It is an interesting option for vegetarians as a complement to algae-based DHA supplementation.

Votre protocole naturel

Urgent erythrocyte fatty acid profile

A complete profile of membrane fatty acids is essential to measure your omega-3 index, the AA/EPA ratio, and precisely identify the extent of the imbalance. This test guides the dosage and duration of supplementation needed.

Investigate the causes of imbalance

Severe deficiency may result from chronically poor diet in fatty fish, excessive consumption of industrial omega-6, fat malabsorption (biliary or pancreatic insufficiency), or high oxidative stress that destroys circulating omega-3.

Intensive EPA and DHA supplementation

Take 2 to 3 g of EPA+DHA daily in triglyceride form (TOTOX below 26), preferably with a meal containing fats to optimize absorption. In case of marked cognitive disorders, prioritize a DHA-rich formula. Minimum three to six month course.

Restructure diet in depth

Consume small fatty fish (sardines, mackerel, anchovies) four to five times per week. Eliminate sunflower, corn, and soy oils in favor of olive and canola oil. Add nuts, ground flax seeds, and chia seeds daily.

Protect omega-3 from oxidation

Omega-3 fatty acids are extremely sensitive to oxidation. Combine your supplementation with natural vitamin E (mixed tocopherols) and dietary antioxidants (berries, turmeric). Keep your omega-3 oils refrigerated and never heat them.

Algae-based DHA for vegetarians

If you do not consume fish, choose a DHA supplement extracted from microalgae (Schizochytrium sp.), the original source of marine omega-3. Algae produce the DHA that fish accumulate by moving up the food chain.
