A lot of people don’t think twice about the health of their thyroid unless they have been diagnosed with some sort of health issue relating to this part of their body. However, the thyroid is an incredibly important butterfly-shaped gland that is near your throat. The thyroid is responsible for controlling many of your internal organs, such as your brain, heart, liver, skin and kidneys. When thyroid function isn’t optimal, this can lead to things like issues with weight, low energy, trouble sleeping, anxiety and even hair loss.

With more than three million new cases of thyroid disease diagnosed each year, now is the perfect time to start paying attention to this part of your body. Regulating your thyroid function naturally can ensure that you feel energetic each day, you’re getting sufficient rest and you’re able to maintain a proper weight. An underactive thyroid can result in weight gain, while an overactive thyroid results in potential weight loss. In this article I want to talk about some of the best thyroid supplements that are being sold for weight loss.

Will taking thyroid supplements help me lose weight?

weight loss and thyroid supplements

If you’re looking to lose weight and are thinking about targeting your thyroid health for this purpose, it’s important that you’ve had your thyroid checked prior to starting any kind of supplement regimen. Your doctor can run some basic blood tests to check the function of your thyroid. Once you have received your results, you’ll be able to tell if you need to address an overactive thyroid gland, an under-active thyroid gland or just thyroid health in general.

Could Help Naturally and Safely Optimize Thyroid Function

T3 is an active thyroid hormone produced by the thyroid that can help boost your metabolism and increase weight loss. A beneficial thyroid supplement should help you boost the production of T3 by way of T4 production (also known as thyroxine). There are a number of nutrients that can help your thyroid balance these hormone productions. This includes zinc, vitamin A, selenium, rhodiola, ashwagandha and phytochemicals.

May Help Boost Metabolism

A lot of people with an under-active thyroid (hypothyroidism) develop this condition because they are deficient in a number of essential nutrients. When you add these nutrients back into the body, this can result in course correction of thyroid dysfunction. The thyroid controls and regulates your metabolism, so this is an all-encompassing approach. The faster your metabolism is, the more calories that are being burned. As long as you’re not over-consuming those calories, you should be able to achieve weight loss with the use of a thyroid supplement that increases metabolism.

Could Help Reduce Stress

Your thyroid works very closely with your adrenal glands, which produce hormones that help the body properly handle stress (in addition to regulating kidney function and growth). When your body is under high levels of stress and your adrenals / thyroid aren’t reacting the way they should, this can cause your metabolism to slow down. You may notice that you experience more bodily symptoms associated with your stress, such as headaches, anxiety or trouble sleeping. A thyroid supplement will keep your hormone production balanced so your stress response is adequate.

May Provide More Energy

When your thyroid is functioning properly, you probably feel energetic and happy throughout the day. When your thyroid is over functioning or not functioning enough, you may notice a shift in your energy. Choosing a thyroid supplement that contains selenium, iron, zinc and iodine will help your body stay focused and energetic over the course of the day. You should also sleep better at night, allowing you to wake up feeling refreshed.

What to Look For

choosing thyroid supplements

Shopping for a thyroid supplement doesn’t have to be difficult. While you can ask your doctor for recommendations on a prescription thyroid medication that will help balance your thyroid function, natural ingredients are often the safest way to go. Let’s talk more about what you should be looking for in a thyroid supplement.

Trust: Brand Transparency and Transparent Ingredients

Always inspect the full list of ingredients that are included in a thyroid supplement. A trustworthy brand will clearly provide this information so you know what you’re consuming. It’s also helpful if you choose a brand that explains where each of these ingredients is sourced. There’s a big difference between a naturally sourced ingredient, versus something that is formed in a lab. General statements about a product’s ingredients, usually means that the brand is hiding something.

Safety: Third Party Tested

Reputable supplement companies invest in third-party testing to check the overall quality, safety and potency of their products. If you determine that a brand has skipped over this process, can you really trust that they care about the quality of the products they’re creating and selling? Results of third-party testing should be transparent to the public, either on their website or they will send you the information if you request it.

Effectiveness: Results and Good Reviews from Verified Buyers

Read through the reviews that you can find on a specific thyroid supplement that you’re interested in purchasing. Are the reviews favorable? Are there concerns that you have after reading about negative experiences? Hearing what real people in the real world experienced when taking a supplement can help paint a picture of what you might experience. Don’t stop at the company’s website. Check other retail sites to see what their reviews look like. Many brands will tailor their reviews to paint a more favorable picture of what they’re trying to sell.

The Bottom Line

It’s likely that you spend time thinking about your heart health, how well your brain is functioning and maybe even the condition of your lungs. However, your thyroid deserves just as much attention as these other important parts. While it may be a small gland that you don’t always realize is there just under your larynx, it’s always hard at work. Your thyroid function can affect anything from the health of your skin to your muscle function.

You can provide your thyroid with support without having to turn to harsh prescription medications or supplements that will result in unwanted side effects. All of the thyroid supplements for weight loss that I’ve discussed here are very gentle, yet provide essential support to your thyroid. It’s a good idea to talk with your doctor before starting any kind of supplements for thyroid support. If you’re dealing with an overactive or under-active thyroid, you should proceed with caution and with the support of a trusted medical professional.

Tips for Success from the Nutritionist

If you think that you’re dealing with weight issues or health problems relating to your thyroid function, reach out to your doctor to find out if you should consider diagnostic tests to see what’s going on. In addition to medical-based solutions, you can try natural supplements and lifestyle changes to maintain a healthy thyroid. Here are some tips that can get you started.

Watch Your Diet

Our immune system plays a big role in the health of our thyroid. Much of our immune system is located in our gut, so it’s important to pay attention to the foods that we choose to eat. Avoid highly processed foods, refined sugar, MSG, high fructose corn syrup and saturated fats in order to prevent inflammation in your gut and GI tract. Stick with foods like vegetables, fruits, fatty fish, lean protein and healthy oils (olive, coconut and avocado).

There are also some foods that are healthy and high in nutrients, but they can actually cause some imbalances for your thyroid. This includes Brussels sprouts, kale, cabbage and cauliflower. Anything that's considered cruciferous (part of the cabbage family) should be eaten in great moderation.

Skip the Plastic

Plastic water bottles, food containers and bags are all damaging to the environment, but did you know that they can also leach chemicals into your food that can impact your thyroid health? Switch to healthier storage options, like stainless steel water bottles and glass food containers.
