The Most Effective Thyroid Support Supplements in 2023 – A Buyer’s Guide
Discover which thyroid support supplements are worth buying, and which ones to watch out for.
Thyroid disorders are more common than you think. While these disorders mainly occur in women, anyone can be affected by thyroid issues. According to the British Thyroid Foundation, about one in 20 people has some kind of temporary or permanent thyroid disorder.1
Your thyroid, which is located in the front of your neck, produces hormones that help control many different functions in your body. These include metabolism, growth, and development of the body.2
Below we will explore some of the common thyroid issues some people may experience, their symptoms, and which natural supplements you should take to help support your thyroid.
What are the Symptoms of an Underactive Thyroid?
Hypothyroidism: This means you have an underactive thyroid.3
- Tiredness
- Weight gain
- Feeling cold
- Poor concentration
- Depression
In the search to find safer alternative options for thyroid support, scientists and researchers have started to study how certain supplements can help boost your thyroid function and health. And we’re here to help. Keep reading to find out what you should look for and what to watch out for when choosing your thyroid support supplements.
Key Ingredients to Look for in a Thyroid Support Supplement
Your diet is essential to your overall health, and that includes your thyroid, as well. Certain nutrients have been shown to be essential for optimal thyroid function, however, sometimes it can be difficult to make sure you’re getting all the nutrients you need. That’s where supplements come in. They can aid in filling in those gaps you may be experiencing.
Numerous studies have been conducted to determine which ingredients are the most effective at aiding thyroid function. Here are a few:
Selenium
Selenium is an important nutrient for the thyroid, as a deficiency in selenium has been shown to lead to thyroid dysfunction.4 Selenium contributes to normal thyroid function, energy-yielding metabolism, and protection from oxidative stress
B Vitamins
All B vitamins are important for good thyroid function, but each has a different role to play. For example, Riboflavin (vitamin B2) contributes to the protection of cells from oxidative stress, normal energy-yielding metabolism, and the reduction of tiredness and fatigue. A lack of it can actually suppress thyroid function.9
An important B vitamin for those having issues with an underactive thyroid is vitamin B12, this is because it contributes to normal red blood cell formation. It also contributes to the reduction of tiredness and fatigue, an energy-yielding metabolism, and more.
Iodine
A deficiency in iodine has been shown to cause thyroid disease.5,6 Iodine contributes to the normal production of thyroid hormones and normal thyroid function.
Zinc
Zinc has been shown to be essential for thyroid production. It’s necessary for healthy levels of thyroid-stimulating hormone (TSH), T3, and T4.7 Zinc also contributes to protection from oxidative stress, as well as a normal macronutrient metabolism.
What Should I Avoid?
Supplements That Aren’t Dairy- or Gluten-Free
If you have a thyroid condition, it is often recommended to cut dairy and gluten. Hashimoto’s thyroiditis, a thyroid condition, can be triggered by gut damage from a diet that is high in dairy and gluten. Cutting out dairy and gluten from not only your diet but assuring it isn’t in your supplements as well, can potentially have great benefits for those with thyroid issues. For example, one study of 2,232 people surveyed showed that of those who went dairy free, 79% felt better and 20% reduced their thyroid antibodies.8
Beware of Online Reviews (Especially on Amazon)
Before purchasing any product, one of the first things we do when researching is to check its online reviews. Unfortunately, these are not always a trustworthy way to measure the quality and effectiveness of a product. Companies often pay for reviews on popular online retailers, like Amazon, to try to trick their way to a five-star rating. While you should definitely consult these reviews before purchasing, do your own research as well.
Generic ingredients
Many companies opt for generic ingredients that aren’t backed by data, meaning the supplement is “watered down” and less effective. Look for ingredients that are clinically proven to provide helpful results.
Your Final Checklist
Now that you know what ingredients to look for and what to avoid, it’s also important to keep the following criteria in mind when purchasing your thyroid support supplement.
Quality Ingredients Recommended by Healthcare Professionals
One of the most important things to look out for when choosing a supplement is that it’s recommended by healthcare professionals. Healthcare professionals are more likely to align themselves with products that are made with high-quality ingredients that truly work.
Money-Back Guarantee
Make sure that the product you buy has a clear money-back guarantee on all product purchases. This is a tell-tale sign that a company knows they’re selling you a great product, so they aren’t afraid to offer you a sort of “insurance” on it.

Overall GradePROS
- Natural Thyroid Support
- Covers Daily Requirements of Iodine & Selenium
- Vegan-Friendly
CONS
- Only 1 Ingredient
- Contains Allergens
- No Money-Back Guarantee
The Bottom Line
CLAV’s Organic Thyroid Support is great for someone looking for something simple. It contains organic kelp powder, which provides you with the daily recommended dose of the nutrients iodine and selenium.
However, this supplement contains organic mustard seed extract, which contains allergens for some. Additionally, although kelp is undoubtedly beneficial for those with thyroid problems, we think that their formula would be more effective if it contained a few complimentary ingredients. Formulas with just one ingredient often do not perform as well as multi-ingredient products.
