The A to Z of thyroid-supporting nutrients

Nutrients play a vital role in maintaining a healthy thyroid. Many of the vitamins and minerals our bodies need to function optimally can only be obtained through the food we eat. The thyroid gland requires iodine as well as many trace elements and vitamins that assist in producing hormones. The right balance of nutrients ensures that your thyroid does not become over- or under-active.

Here are five nutrients that help you maintain a healthy thyroid:

  1. Tyrosine

Tyrosine is one of the 22 essential amino acids, the building blocks of protein in the body. It is combined with iodine in the thyroid to create thyroid hormone. Foods such as pumpkin seeds, avocados, soy products and common meats are all good sources.

  1. Vitamin A

Besides being important for maintaining eye health, Vitamin A plays an important part in keeping your thyroid in order. Vitamin A helps to regulate the production of thyroid-stimulating hormone (TSH) and the body needs Vitamin A to convert T4 to T3. Dairy products and fish are both good dietary sources.

  1. Vitamin B12

Low presence of Vitamin B12 in the body is associated with decreased levels of an important enzyme that activates thyroid hormone. If your thyroid is already underactive, your body is unable to absorb B12 adequately. You can take B12 as a supplement or as injections.

  1. Vitamin D3

Vitamin D3 counteracts the excessive excretion of calcium in overactive thyroids, helping to safeguard against osteoporosis. Vitamin D deficiency is associated with autoimmune thyroid disorders. In addition to helping prevent these, supplementing your diet with Vitamin D3 is good for protecting yourself from thyroid cancer.

  1. Zinc

This essential mineral is required for the production of active thyroid hormone (T3). It also stimulates another important gland in the endocrine system, the pituitary gland, which is connected to the base of the brain and also provides crucial hormones.


You can supplement your diet with all the above nutrients via a healthy eating plan. Schedule a consultation with Doctor Allie so she can help you find a healthy diet that will create hormonal balance and sustained wellness.


  1. Hi Alison,
    great to see your site coming through social media.

    Alison, my neighbour has hyperthyroid and wants to take the Essentials which has a bit of iodine in it. I have checked on Dr Gerrys and Sanovivs site and they only talk about hypothyroid.
    What are your USANA nutritional supplement recommendations for hyper??

    1. Doctor Allie

      I would go with the Essentials as a start up & assess what else is needed. So as for anyone else, basic would be Essentials, Biomega; optimal would include Profavanol; Important to consider the increased risk of osteoporosis so Active Calcium & other measures to reverse this trend.
