Micronutrition
Nutritional approach focused on optimizing micronutrient intake — vitamins, minerals, trace elements, fatty acids and amino acids — to correct functional deficits and restore metabolic balance.

Presentation
Micronutrition is a discipline developed in the 1990s by Dr. Christian Leclerc and formalized by IEDM (European Institute of Dietetics and Micronutrition). It stems from the observation that modern diet, even when apparently balanced, can generate micronutrient deficits (vitamins, minerals, trace elements, essential fatty acids, amino acids, probiotics) that impair cellular function and promote functional disorders.
Micronutrition goes beyond recommending healthy eating: it precisely identifies individual deficiencies and proposes targeted corrections through diet and supplementation.
Core Principles
Micronutrition rests on several axes. Deficit evaluation uses functional questionnaires (DNS questionnaire — Nutritional Deficits and Symptoms), targeted biological assessments (ferritin, vitamin D, erythrocyte magnesium, zinc, selenium, fatty acid profile) and functional symptom analysis. Dietary correction prioritizes high nutritional density foods and adapts cooking methods to preserve micronutrients. Rational supplementation fills identified deficits with bioavailable forms and physiological dosages.
Application Domains
- Intestinal ecosystem: intestinal permeability, dysbiosis, IBS, food intolerances — probiotics, glutamine, zinc, vitamin A
- Immunity: recurrent infections, allergic terrain — vitamin D, zinc, selenium, strain-specific probiotics
- Neurobiology: mood disorders, anxiety, sleep, concentration — magnesium, tryptophan, omega-3 EPA/DHA, B vitamins
- Energy metabolism: chronic fatigue, sports recovery — iron, CoQ10, B vitamins, magnesium
- Cellular protection: oxidative stress, aging — vitamins C and E, selenium, zinc, polyphenols, glutathione
- Osteoarticular health: pain, osteoporosis — vitamin D, vitamin K2, calcium, magnesium, silicon
Precautions
Supplementation never replaces a balanced diet. Drug interactions must be verified (e.g., vitamin K and anticoagulants). Some micronutrients can be toxic at high doses (iron, vitamin A, selenium). Biological assessments must be interpreted within the overall clinical context. Micronutrition complements conventional medical follow-up.
