How to choose the best multivitamin for underactive thyroid

What you will read in this article:

Hypothyroidism is a condition in which the thyroid gland is unable to produce enough thyroid hormones, which slows down the body's metabolism. Hypothyroidism increases the risk of nutritional deficiencies in many ways. First, it reduces stomach acid. Stomach acid is necessary for the absorption of many minerals such as iron, calcium and especially vitamin B12. For this reason, hypothyroid patients are prone to iron deficiency anemia and megaloblastic anemia. hypothyroidism diet along with taking the best multivitamin for hypothyroidism can help sufferers better control this disease.

Also, the most common cause of hypothyroidism is the autoimmune disease Hashimoto usually associated with other intestinal or gastrointestinal autoimmune diseases, which also affects intestinal health and the general absorption of nutrients. puts And finally, the process of this disease and the reduction of metabolism also affects the transformation and activation of micronutrients in the body.

importance Appropriate multivitamin use in hypothyroidism

Consumption of a suitable multivitamin is necessary for people with hypothyroidism; Because in addition to compensating common nutritional deficiencies caused by this disease, it helps to improve thyroid function. It is noteworthy that even following a balanced diet in hypothyroidism does not make you need to take multivitamins. because in the case of this disease, the vitamins received from the diet are often not properly processed by the body; Therefore, multivitamins play a vital role in supporting these processes and ensuring optimal use of nutrients by the body. Taking multivitamins for hypothyroidism is important from the following aspects:

Increasing the effectiveness of treatment and regulation of metabolism

Appropriate supplements help the body process levothyroxine better by providing essential micronutrients and increase the overall effectiveness of the treatment.

Reduce severe fatigue

Compensating for nutritional deficiencies helps to reduce annoying symptoms such as excessive fatigue and low energy levels.

regulating body temperature

Vitamins and minerals in the right multivitamin play a role in regulating the body's basal temperature by supporting cell metabolism. Therefore, they are effective in reducing the feeling of chronic cold caused by hypothyroidism.

Improving cognitive performance

Supporting thyroid function and eliminating the deficiency of vitamins such as B12 helps to reduce brain fog, improve concentration and mental ability.

Mood improvement

Mood swings, depression and anxiety are common problems in hypothyroid patients. Taking the right multivitamin helps to stabilize the mood and reduce emotional fluctuations by eliminating nutritional deficiencies related to these cases.

Fitness support

The appropriate multivitamin plays a role in supporting fitness and weight management in hypothyroid patients by improving thyroid function and regulating metabolism.

Antioxidant support and tissue protection

Certain nutrients such as selenium protect the sensitive tissue of the thyroid gland from oxidative damage with its strong antioxidant function.

Improving hormone conversion and thyroid function

Micronutrients such as selenium and zinc are critical for converting the inactive T4 hormone into the active T3 form.

modulation of immune response and reduction of inflammation

Vitamin D deficiency is very common in Hashimoto's patients. Compensating for the deficiency of this mineral helps to regulate the immune system and reduces the severity of the autoimmune attack and inflammation of the thyroid gland.

Compensation for common secondary deficiencies

Hypothyroidism interferes with the absorption of vitamin B12 by reducing the production of stomach acid. A suitable multivitamin compensates for this common deficiency by providing a sufficient dose of B12 and prevents the occurrence of symptoms such as anemia and nerve damage.

Hair loss control

Hypothyroidism and secondary deficiencies such as vitamin B12, zinc, iron and ferritin are the main cause of hair loss in these patients. By compensating these deficiencies, multivitamin strengthens the hair growth cycle and helps to reduce severe shedding and improve the health of the follicles.

On:

Zinc is vital for making thyroid hormones and helping them function properly.

Vitamin :B12

The presence of B12 in multivitamins is necessary to prevent fatigue and anemia caused by its deficiency.

Vitamin D

Getting a sufficient amount of vitamin D is necessary to strengthen the body's immune system and reduce inflammation of the thyroid gland.

Magnesium

This mineral helps reduce muscle cramps and general fatigue, as well as increase energy levels in hypothyroid patients.

tips Multivitamin use in hypothyroid patients

In addition to the presence of essential nutrients in a multivitamin suitable for hypothyroidism, it is very important to pay attention to the interaction of some nutrients with levothyroxine and also observe the correct timing of use. The following are the most common nutrients that interfere with levothyroxine absorption.

  • Iodine: If your hypothyroidism is caused by Hashimoto's disease, taking high doses of iodine leads to the exacerbation of inflammation in the thyroid gland. In this case, you should choose a supplement with a low dose of iodine or without iodine (Iodine-Free).
  • Iron and calcium : The multivitamin you choose should not contain high doses of iron or calcium. If these two minerals are present in the multivitamin, you should leave at least 4 to 6 hours between taking the thyroid medication and using the supplement.
  • Biotin: Taking high doses of biotin does not affect thyroid function; But it causes false changes in thyroid blood test (TSH) results. If your multivitamin contains biotin, be sure to stop taking it a few days before the blood test.
  • Distance from levothyroxine: As a general rule, multivitamins and any other supplements should be taken at least 4 hours apart from thyroid medication (levothyroxine) to avoid interference with drug absorption. The best time to take a multivitamin is during lunch or in the evening; While levothyroxine should be taken in the morning on an empty stomach.

Last letter

Successful management of hypothyroidism, in addition to receiving the appropriate dose of levothyroxine, is also related to meeting nutritional needs. A proper multivitamin is a vital support in controlling hypothyroidism. In addition to compensating for common nutritional deficiencies caused by this disease (such as B12 and vitamin D), multivitamins help provide essential elements such as selenium and zinc. These minerals play an effective role in converting the T4 hormone into the active form of T3. However, keep in mind that multivitamins containing high calcium and iron should be taken at a proper distance from levothyroxine due to impaired absorption of levothyroxine. It is recommended to consult a specialist doctor to choose the best multivitamin for underactive thyroid.
