Descrizione

T Mix (T3-T4 mix) è una combinazione di ormoni tiroidei che include triiodotironina (T3) e tiroxina (T4), le uniche sostanze biologicamente attive note a contenere iodio. Questi ormoni svolgono due funzioni fondamentali:

• durante la crescita sono essenziali per lo sviluppo normale dell’organismo, in particolare del sistema nervoso centrale;

• negli adulti regolano il metabolismo energetico, influenzando quasi tutti gli organi e i tessuti, la velocità del consumo energetico e la produzione di calore.

La ghiandola tiroidea mantiene ampie riserve di ormoni tiroidei. Il loro metabolismo avviene principalmente nel fegato, ma anche nei tessuti bersaglio come il cervello. I livelli plasmatici di T3 e T4 sono regolati in modo preciso dall’ipofisi tramite il TSH, secondo un meccanismo di feedback negativo. Il T4 rappresenta l’ormone principale secreto dalla tiroide e viene convertito in T3, la forma metabolicamente più attiva, soprattutto a livello dei tessuti periferici.

Gli ormoni tiroidei agiscono principalmente attraverso recettori intracellulari, modulando l’espressione genica e influenzando numerosi processi metabolici.

Finalità d’uso

Molti pazienti in terapia sostitutiva presentano difficoltà nella conversione della levotiroxina (T4) in triiodotironina (T3), nonostante l’organismo necessiti di entrambi gli ormoni. Le cause possono includere sovraccarico epatico, carenza di zinco, deficit nutrizionali o eccesso di iodio.

Due to the limitations of T4 monotherapy, patient dissatisfaction remains high. For this reason, numerous studies have analyzed the benefits of combined T3 + T4 therapy . The T3-T4 mix allows for normalization of T4 and TSH levels and maintenance of T3 at least in the mid-normal range.

T Mix is ​​used in replacement therapy in several conditions, including:

• post-thyroid resection

• radioiodine treatment

• thyroid oncological pathologies

• suppressive therapy

It is indicated for hypothyroidism of any etiology , including:

• primary and secondary hypothyroidism

• diffuse or mixed euthyroid goiter

• subacute and autoimmune thyroiditis

• thyroid cancer (post-surgical)

• obesity associated with hypothyroidism

---

Dosage

Treatment with T Mix generally starts with low doses , which are gradually increased to the therapeutic dose over 3–4 weeks .

In elderly patients or those with cardiovascular disease, doses should be reduced to limit the risk of cardiac side effects. During pregnancy and childhood, the need for thyroid hormones may increase. In some cases, beta-blockers may be prescribed to improve tolerance to therapy.

How to use

Generally:

• start with 1 tablet per day

• every 5–6 days increase by 1 tablet

• the maximum is 3 tablets per day , divided into several administrations

The standard cycle lasts 5–7 weeks , followed by a break of at least 6 weeks . This approach can help restore normal thyroid function. The T3-T4 mix is ​​sometimes combined with clenbuterol to enhance the fat-burning effect.

• Average dosage: 1–3 tablets per day

• Effective scheme: pyramid method (1-2-3-3-2-1)

---
