FAQ:

Q: What are the best natural thyroid supplements?

A: Iodine is probably the best supplement out there because it helps in creating hormones. It can be found in milk, cheese, poultry, seaweed, and iodized salt. Iodine makes up most of T3 and T4, the two primary hormones that the thyroid gland produces.

Q: What is the best over the counter for thyroid?

A: Over-the-counter supplements can play an integral part in the comprehensive management of hypothyroid but cannot replace supplementation by Thyroid hormones where indicated. Some of the important supplements are Vit D, Vit B12, Omega-3, Curcumin, Amino acids, Iodine, Mg, Zn and Se. Detoxifying agents such as N-Acetyl Cysteine also can be helpful.

Q: What supplements support thyroid function?

A: Certain things can boost your thyroid function, including multi-minerals like zinc, iodine, copper, magnesium and selenium. Natural dietary supplements that are rich in trace minerals and iodine will help in boost thyroid function.

Q: Is it possible to boost thyroid naturally?

A: Choosing the right vegetables from the garden has been shown to improve thyroid function. Many natural foods serve as thyroid boosters. For example, foods rich in iodine, such as broccoli, turnips, cauliflower and cabbage, naturally work to boost thyroid function.
