Expert opinion

"Thyroid issues can manifest as fatigue, irritability, drowsiness, difficulty maintaining weight, and insulin resistance. They are often accompanied by lack of energy, low mood, and constant hunger. Don't ignore these symptoms – simple blood tests such as TSH, FT3 or FT4 can help with the diagnosis. It is also crucial to support your thyroid through a healthy lifestyle: managing stress, getting restorative sleep, and eating a balanced diet. Important ingredients include zinc, selenium, iodine, and vitamins E and D3, which support its proper functioning."

Get to know the active ingredients of the ThyroBest – 3-Step Thyroid Support supplement

Vitamin E

Vitamin E is a group of compounds called tocopherols, which is fat-soluble. Stored in the body, mainly in fat tissue and in the adrenal glands. Vitamin E is an antioxidant that protects against cell damage and oxidative stress.

Inositol (vitamin B8)

Inositol was once considered one of the B vitamins (vitamin B8). Nowadays, however, it is treated as a vitamin-like compound since it has been discovered that the human body can synthesize it on its own. This synthesis primarily takes place in the liver and brain. In the course of certain diseases, the bodys own production of inositol may be insufficient. Supplying it to the body through diet and/or dietary supplements may have a beneficial effect on its functioning. Inositol is a component of cell membranes, body fluids, glycolipids, and glycoproteins.

Vitamin D3

Vitamin D3 (cholecalciferol) was first isolated from cod liver oil in 1922 by the American scientist Elmer McCollum, but it was not until the 1930s that its chemical structure was determined at a German University under the supervision of Professor Adolf Windaus. It influences many processes, including the regulation of calcium and phosphate metabolism, as well as the impact on immunity.

Vitamin K2 MK7

Vitamin K was discovered in 1930 by Henrik Dam, who conducted research on blood clotting. What properties does vitamin K have? This chemical is often referred to as the "coagulation vitamin". This is because vitamin K aids in the blood coagulation process – supporting the action of blood factors such as prothrombin.

N-acetyl L-cysteine

N-acetylcysteine is an acetylated derivative of the sulfur amino acid L-cysteine. After ingestion, NAC is absorbed in the digestive tract and then converted into L-cysteine in the liver, which in turn, together with glycine and L-glutamic acid, can be used to produce glutathione – an organic chemical compound with strong antioxidant properties.

Zinc

It is a cofactor for nearly 300 enzymes and an even greater number of proteins, such as pyruvate carboxylase, superoxide dismutase, alcohol dehydrogenase, aromatase, homocysteine breakdown, insulin synthesis, and heme – making it essential for proper protein metabolism, genetic material, cell growth, division and function, energy supply, and more.

Selenium

Selenium is a trace element that plays a huge role in the proper functioning of the entire organism. Providing the body with selenium at the appropriate level is very important, as its deficiencies may affect autoimmune, cardiovascular and cancer issues.

Iodine

In the human body, iodine is found primarily in the thyroid gland. It is necessary for the production of thyroid hormones thyroxine and triiodothyronine. These hormones influence, among other things, the proper development and functioning of the brain, nervous system, and skeletal system. They participate in the metabolism of many components, e.g., proteins, fats, carbohydrates, and vitamins. They regulate the processes of cell growth and maturation and are also responsible for maintaining proper body temperature.

L-tyrosine

It is an amino acid that can help improve mood, reduce fatigue, and help control appetite, which is a major factor in weight loss.

Taurine

Taurine is an amino acid that occurs naturally in animal tissues. Its chemical name is 2-aminoethylsulfonic acid. Due to its chemical structure, taurine does not have the ability to form peptide bonds. For this reason, it is not a building block of proteins – it is a non-protein amino acid. It is found mainly in skeletal muscle, heart, brain, and retina.

Glycine

Glycine is an endogenous amino acid that is synthesized in the body. It is responsible for the proper functioning of the nervous system, supports liver function, and is a component of collagen, acting as a building block.

Lactoferrin

Lactoferrin is a protein with antibacterial, antiviral, antifungal, immunoregulatory and anti-inflammatory properties. In addition, lactoferrin chelates iron ions, thanks to which it also acts as a regulator of iron absorption, especially in newborns and small children.

Japanese Pagoda Tree Flower Extract

Quercetin belongs to a group of bioactive plant compounds with antioxidant activity, called flavonoids. It is a natural plant dye found in many fruits and vegetables, e.g., in green tea leaves, onions, broccoli, apples, berries, grapes. Quercetin has valuable anti-inflammatory and anti-cancer properties and is beneficial for the cardiovascular system and metabolism.

FAQ

Can ThyroBest be used during pregnancy?

There is currently a lack of sufficient scientific research on the safety of forskolin use during pregnancy. Therefore, it is recommended to use ThyroBest during the preparation period for pregnancy to support the proper functioning of the thyroid gland. However, its use during pregnancy should only take place after consultation with the attending physician, who will best assess whether it is appropriate.

Can ThyroBest be used while breastfeeding?

There is insufficient research evidence regarding the use of forskolin during breastfeeding. For this reason, it would be advisable to use ThyroBest after the end of breastfeeding to support thyroid function but use during breastfeeding should be discussed with a pediatrician first.

Is ThyroBest only intended for people over 75 years of age?

No, the ThyroBest dietary supplement is not only intended exclusively for people over 75 of age. This provision results from legal requirements related to the vitamin D3 content in the product, which is 4000 IU per serving. This is the upper limit of the recommended daily dose of vitamin D3, at which the regulations require a statement to be included that the supplement is intended for older people. In practice, a dose of 4000 IU may be appropriate for people in different age groups, particularly in cases where testing indicates a vitamin D3 deficiency or increased requirement (e.g., in winter, individuals with insulin resistance, autoimmune diseases or hypothyroidism). However, as a manufacturer, we are obligated to comply with regulations that require additional warning. Therefore, before you start using a supplement containing this dose of vitamin D3, it is recommended to perform a 25(OH)D blood test and discuss the results with your doctor. This way you can ensure that supplementation is tailored to your individual needs.

Can ThyroBest be used by people with low blood pressure?

ThyroBest is not recommended for people with low blood pressure. It is worth consulting your doctor before starting any supplementation.

Can ThyroBest be used by children and adolescents?

The ThyroBest dietary supplement was developed for adults, but its active ingredients, such as iodine, selenium, and zinc support thyroid health, making it potentially also suitable for adolescents with thyroid problems, such as hypothyroidism or Hashimotos. The use of the preparation should be discussed with a pediatrician.

Can ThyroBest be used in case of Hashimotos disease?

Yes, the ThyroBest dietary supplement can be used in case of Hashimotos disease. Its composition has been developed to support thyroid function, especially in situations where there are deficiencies of nutrients such as iodine, selenium, or zinc, which are crucial for the production of thyroid hormones and protecting its cells from oxidative stress.

Can ThyroBest be used for hypothyroidism?

Yes, ThyroBest supports thyroid function, especially in the case of hypothyroidism, but you should be careful when taking medications for hypothyroidism (T4 – levothyroxine), as the supplement may intensify the effect of the drug and its dose may be calibrated under the supervision of a doctor.

Can ThyroBest be used for hyperthyroidism?

No, ThyroBest dietary supplement should not be used in case of hyperthyroidism. Its formula was designed primarily to support people with hypothyroidism, Hashimotos or other conditions resulting from thyroid hormone deficiency. In case of hyperthyroidism (i.e., when the TSH level is low and fT3 and fT4 are high), ThyroBest supplementation is not recommended. This also applies to cases of hyperthyroidism associated with Graves disease, even if it coexists with Hashimotos disease.

Can ThyroBest be used in case of Graves-Basedows disease?

No, ThyroBest dietary supplement is not recommended for people with Graves-Basedows disease. It is an autoimmune form of hyperthyroidism in which the thyroid gland works too hard, producing excess hormones. The use of preparations supporting thyroid function in such a case is not recommended. ThyroBest was created to support people with hypothyroidism and Hashimotos disease, conditions in which the function of the thyroid is weakened.

Can ThyroBest be used for thyroid nodules?

The use of the ThyroBest in the case of thyroid nodules should be discussed with an endocrinologist first. Each case requires individual evaluation because the nature of the nodules and their effect on thyroid function may vary. A thorough diagnosis and consultation with a specialist is the key to making a safe and appropriate decision regarding supplementation.

Can ThyroBest be used after thyroid removal?

Yes, the ThyroBest dietary supplement can be used after thyroid removal surgery. People who have undergone such surgery usually take levothyroxine (T4), which is converted in the body to triiodothyronine (T3) – a process that takes place mainly in the liver and intestines. The ingredients contained in ThyroBest can support this process and the overall balance of the body.

Can ThyroBest be combined with other Best Lab products?

Yes, the ThyroBest dietary supplement can be successfully combined with other BestLab products. Depending on your needs and expectations, ThyroBest supplementation can be complemented with preparations that support other aspects of health. For example, the BestBiotic probiotic will take care of healthy intestinal flora, which is crucial for the functioning of the immune system and the absorption of nutrients. In turn, the colostrum in ImmuBest will help strengthen the bodys natural immunity, especially in periods of greater exposure to infections.

Can ThyroBest be used preventively to support thyroid health?

Yes. ThyroBest contains vitamins, minerals, and plant extracts with a versatile effect, including adaptogenic effects, so the product can be used prophylactically.
