DIIODOTYROSINE – DIT, an iodine-containing amino acid, is a precursor of thyroid hormones: triiodothyronine (T3) and thyroxine (T4). DIT stimulates processes related to protein synthesis, increases the metabolic rate and affects the action of other hormones (including insulin). Some weight loss supplements combine diiodotyrosine with additional fat-burning ingredients. As regulations tighten, it is being withdrawn from the sports supplement industry. The only people who should take this product are people over 18 years of age and people who are healthy and free from hyperthyroidism, high blood pressure and neurological disorders.

Dosage: 25 mcg per day.
