Overview
You support tired patients who struggle to lose weight or remain lost despite levothyroxine treatment, and their thyroid panel comes back "strictly normal". This training gives you the physiological and biochemical keys to spot these functional hypothyroidisms that TSH alone misses, understand their deep cause and build genuinely personalised management.
What you will learn
- Master the synthesis and activation of thyroid hormones (the role of iodine, tyrosine, TPO, deiodinases, NIS and membrane transporters) to pinpoint exactly where the mechanism seizes up in each patient.
- Reason along four main axes of hypothyroidism (defective T4 synthesis, defective conversion to T3, excessive conversion to reverse T3, defective T3 bioactivity), then refine by categories and subcategories to individualise the protocol.
- Conduct a structured clinical collection of functional signs and score it, in order to spot a thyroid dysfunction even when routine biology is reassuring.
- Prescribe and interpret a complete functional biology assessment, in particular urinary hormone measurements on 24-hour urine, ioduria, DIO2 polymorphism, anti-TPO and anti-TG antibodies, and the salivary cortisol cycle.
- Build a micronutritional, phytotherapeutic and dietary strategy tailored to the axis at fault (iodine, selenium, iron, zinc, vitamins D and A, omega-3, glutathione, guggulsterone, kaempferol, ashwagandha).
- Place hormonal treatments (levothyroxine alone or a T4 and T3 combination) within a logic of optimising the terrain.
On the programme
- Physiology and biochemistry of the thyroid gland, from iodine absorption to the peripheral conversion of T4 to T3.
- The four axes of thyroid dysfunction, their categories and subcategories, as a management decision tree.
- The clinical collection and the functional questionnaire of hypothyroidism signs, with a scoring system.
- The functional biology of the thyroid, the value of 24-hour urinary measurements and the DIO2 genetic polymorphism.
- The key micronutrients of thyroid function, their target status, forms and supplementation methods.
- The phytoactives studied in thyroid disorders.
- The systemic links to explore, mitochondria, adrenals (cortisol and aldosterone), gut ecosystem and metabolic endotoxaemia, environmental pollution.
- A module dedicated to Hashimoto's thyroiditis, autoimmunity, gluten, oxidative stress, modulation of the immune response and the controversy around iodine.
- Commented clinical cases to anchor the reasoning.
Who it is for
This training is for doctors and pharmacists, as well as healthcare professionals engaged in micronutrition and functional medicine, who prescribe, dispense or support patients presenting with hypothyroidism or Hashimoto's thyroiditis.
At the end of the training
You will be able to spot a functional hypothyroidism behind a normal routine assessment, then trace back to the deepest cause by reasoning through axes and subgroups. You will be able to prescribe and interpret a relevant functional biology assessment, and offer overall management combining micronutrition, phytotherapy, a dietary model and, when justified, support of the hormonal treatment. You will thus have a 360-degree view of thyroid function to individualise your protocols patient by patient.

Frequently asked questions
Why is T4 alone (levothyroxine) often insufficient to correct hypothyroidism symptoms?
T4 has no direct physiological action: it is a prohormone whose only role is to be converted into T3, the active form. However, peripheral T4-to-T3 conversion can be insufficient for many reasons (selenium deficiency, DIO2 polymorphism, heavy metals, excess reverse T3). Moreover, supplying synthetic T4 exerts negative feedback centrally and can inhibit endogenous production, without necessarily guaranteeing an optimal T3 level.
Should iodine be avoided in all patients with Hashimoto's thyroiditis?
Dr Anne Lucas, PharmD, recommends not supplementing with iodine as long as anti-TPO antibodies remain elevated, since an excessive intake stimulates TPO, increases hydrogen peroxide production, and worsens inflammation. Gradual reintroduction of iodine (100 to 150 micrograms maximum) is considered once antibodies have significantly decreased and oxidative stress is under control, always combined with selenium.
Which biomarker should be tested first to assess intestinal hyperpermeability in a Hashimoto's patient?
Dr Anne Lucas, PharmD, recommends testing LBP (LPS-binding protein) first, rather than zonulin. Elevated LBP reflects metabolic endotoxemia and is directly correlated with a reduction in thyroid hormones, receptor blockade, and increased conversion to reverse T3. In the context of an autoimmune disease, zonulin and a few targeted food IgGs can be added.
How can a patient on Euthyral present with signs of hypothyroidism when her blood free T3 is normal?
Two main mechanisms can explain this paradoxical picture. First, an excess of reverse T3 (axis 3) due to overactivation of DIO3 under the effect of hypercortisolism or chronic stress blocks the action of active T3. Second, adrenal exhaustion (axis 4) with a drop in cortisol prevents T3 from entering the target cell. Testing the salivary cortisol cycle and 24-hour urinary thyroid hormones (in particular reverse T3) makes it possible to determine which of these two hypotheses applies.
What is the practical difference between Brazil nuts and standardized selenium supplementation for the thyroid?
Brazil nuts have a highly variable selenium content depending on soil richness, which is acceptable for non-autoimmune hypothyroidism where a degree of imprecision is tolerable. In Hashimoto's thyroiditis, Dr Anne Lucas, PharmD, prefers standardized supplementation at 100-200 micrograms of selenomethionine per day to obtain reproducible doses, since studies show a reduction of anti-TPO antibodies of about half with consistent intakes.
Which micronutrients are essential for thyroid hormone synthesis, and how can they be justified physiologically?
Iodine (the structural precursor bound to thyroglobulin), tyrosine (the amino acid backbone for iodination), selenium (a cofactor of TPO and the deiodinases), iron (the TPO hemoprotein), magnesium and mitochondrial substrates (for the ATP needed by the NIS transporter), and omega-3s (membrane fluidity for NIS, TPO and MCT8) are all required. A deficiency in any one of these elements can block a specific step in the synthesis chain.
Why is it justified to remove gluten in a Hashimoto's patient even without confirmed direct hypersensitivity?
Even without a confirmed allergy or non-celiac gluten sensitivity, gliadin activates zonulin secretion, which opens the intestinal tight junctions and worsens hyperpermeability. This increases systemic inflammation and immune dysfunction. Gluten avoidance is therefore justified on mechanistic grounds, independent of a hypersensitivity diagnosis.
Why prefer 24-hour urinary thyroid hormone testing over standard blood testing?
Dr Anne Lucas, PharmD, observes in practice that normal blood free T3 levels can be markedly low in 24-hour urine, which better reflects the thyroid's actual day-to-day function. Conversely, she has never observed a low urinary reverse T3 alongside a normal blood reverse T3. Urinary testing thus provides a functional view that blood panels do not capture, and is essential not to miss subclinical hypothyroidism.
What is the mechanism by which repeated low-calorie diets lead to weight-loss resistance?
Severe, prolonged caloric restriction stimulates the conversion of T4 into reverse T3 (axis 3) at the expense of active T3. Reverse T3 competitively blocks T3 receptors, lowering the basal metabolic rate. The patient ends up in a vicious circle: the more she restricts, the more her metabolism slows down. The only way out is a gradual normalization of caloric intake (returning to roughly 1800 kcal/day), which lowers reverse T3, even though this implies a transient weight regain.
At what dose should selenium be given in Hashimoto's thyroiditis, and how should it be combined?
Supplementation of between 100 and 200 micrograms of selenium per day can reduce anti-TPO antibodies by 25 to 50%. It is advisable to take it on an empty stomach and combine it with vitamin E at 400 IU per day. Brazil nuts are not suitable in this context: a titrated supplement should be preferred.
How should vitamin D status be assessed and optimized in a hypothyroid patient?
Vitamin D acts at several levels of the hypothalamic-pituitary-thyroid axis and is also needed for T3 to enter the cell. Outside an inflammatory or autoimmune context, the target level is at least 60 ng/mL; in the presence of inflammation or autoimmunity, the target is rather 80 to 90 ng/mL. Status should be assessed systematically in any patient presenting a clinical picture of hypothyroidism.
Why should vitamin C and iron not be combined in supplementation, when vitamin C is recommended with iron-rich foods?
In food intake, vitamin C improves the bioavailability of non-heme iron by keeping iron in its Fe2+ form. In supplementation, however, combining vitamin C with a ferrous salt generates a pro-oxidant reaction, producing hydroxyl radicals via the Fenton reaction. Dr Anne Lucas, PharmD, recommends combining iron with vitamin E or selenium in supplementation, and taking it at least 4 hours apart from thyroid hormones.
