If the side effects are severe and do not subside within a couple of days, you must stop consuming the supplement and consult your doctor immediately.

Summary: Mild side effects may be experienced initially for the first few days. They will resolve on their own. For those with any pre-existing medical condition, consultation with your physician is mandatory.

Frequently Asked Questions (FAQs)

Which foods can ensure proper thyroid function?

Foods that are rich in minerals and essential trace nutrients and are needed for the regular functioning of the thyroid should be included in your diet to ensure that you have a healthy thyroid.

Foods like fish and kelp are rich sources of iodine, whereas mushrooms, spinach, and broccoli are rich in zinc and copper. For selenium, you can have eggs and whole grains.

What is the difference between thyroid medications and thyroid supplements?

Thyroid medicines are artificially-prepared replacements of thyroid hormones that are prescribed to manage hypothyroidism.

Thyroid supplements, on the other hand, have been developed with the help of vitamins and minerals that help your body to maintain normal thyroid function.

Which vitamins and minerals are beneficial for the thyroid?

The deficiency of B vitamins has shown some association with thyroid dysfunction. However, it is not clear if supplementation with B vitamins alone can restore the normal functioning of the thyroid.

Minerals like iron, selenium, copper, and zinc are essential for the maintenance of a healthy thyroid.

The Final Note

Thyroid supplements aim at maintaining the thyroid gland in a healthy state and improve energy levels and concentration.

They can never be substituted for thyroid medications but can be used only as adjuncts for thyroid wellbeing.

Just like any other health supplement, thyroid supplements should be taken only after consulting with your healthcare provider to avoid any subsequent health problems.

Children and women who are pregnant or breastfeeding should refrain from using thyroid supplements to avoid any health complications.
