Thyroid & Hormone Balance

A broad collection of 464 products - iodine, selenium, zinc, B vitamins, vitamin D and multinutrient formulas, in capsules, tablets, liquids, sprays and lozenges. Brands include Viridian, Solgar, Lamberts, Terranova, Biocare, Natures Aid and HealthAid.

Which nutrients have approved claims?

Iodine contributes to the normal production of thyroid hormones and to normal thyroid function. Selenium also contributes to normal thyroid function. Zinc contributes to normal cognitive function and to the maintenance of normal testosterone levels in the blood, and vitamin B6 contributes to the regulation of hormonal activity.

Iodine is one to be careful with

Both too little and too much iodine can affect the thyroid, and more is not better. Seaweed and kelp supplements can be very high in iodine and the content varies considerably between products and batches. If you have a diagnosed thyroid condition or take thyroid medication, do not start an iodine supplement without speaking to your GP.

Selenium and brazil nuts

Selenium is the other mineral most associated with thyroid function, and it has a relatively narrow range between a useful intake and too much. Brazil nuts are an unusually concentrated food source. Check the percentage NRV on any supplement before combining several products that each contain it.

This is a category for talking to your GP

Thyroid symptoms - fatigue, weight change, feeling cold, hair thinning - overlap with a great many other things, and thyroid function is measured with a simple blood test. Get tested rather than guessing. Supplements in this collection support normal function in people whose intake is short; they are not a substitute for diagnosis or for prescribed thyroid medication.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.
