Natural Factors Thyroid Health Formula Review

Manufacturer’s Claims

This review outlines the details of the product Thyroid Health Formula by Natural Factors. This claims to be a natural supplement to support your thyroid. The thyroid is one of the most important glands in the body that affects your overall health. If your thyroid is not healthy, your whole well-being suffers. This product claims to provide organic ingredients to nourish the thyroid.


Iodine is one of the most important ingredients for the thyroid as it is required for the thyroid to make the thyroid hormones. If the body has an iodine deficiency, this will affect the manufacturing of these hormones which will affect the body. Panthothenic acid is included for the production of energy.  L-tyrosine is an important amino acid that works with iodine to promote the thyroid hormones. This product seems to be missing key ingredients such as zinc which works well with copper to produce thyroid hormones, as well as kelp and selenium.


According to the label, two capsules should be taken once or twice a day. It is not clear when you should take this product once a day and when twice.


This product is available for purchase online from different retailers. We found the price on Amazon to be $12.18 for a bottle containing 60 capsules. This price will vary depending on the retailer. One bottle should last two weeks to a month depending on the dosage you take.

Possible Side Effects

There is no mention of any side effects with this product, though one user complained of headaches. This product is designed for adults only and should not be given to children.


The manufacturer does not seem to offer a satisfaction guarantee with this product. One customer review mentioned a 30-day money back guarantee, but this is most likely from the retailer and not the manufacturer. It is important to pay attention to the return policy of the retailer where you are buying the product.

Natural Factors Thyroid Health Formula Review – The Bottom Line

This product contains some of the essential ingredients to be useful for nourishing the thyroid. It also comes at a fairly decent price. This product is missing a few key ingredients found in other supplements such as zinc and selenium which could make this product less effective than some others. The dosage is also not clear enough and comes across as more of a suggestion, and the dosage you take affects the effectiveness and may also contribute to side effects. The lack of a satisfaction guarantee is also disappointing because if the product does not work for you, you will have no recourse to get your money back. There are other products on the market that contain more ingredients to benefit the thyroid and that also come with a money-back guarantee.
