Thyroid T3 Review - Does This Hormone Supplement Actually Work? Are side effects and lack of real results deal breakers?

Editor's Review: 2.8 / 5.0

thyroid-t3-product-imageGive me two minutes of your time and I’ll tell you whether Thyroid T3 actually works. We took the time to create a comprehensive review, examining the ingredients, side effects, scientific studies and customer-service quality. Plus we sorted through all kinds of user comments and reviews from all over the internet. Finally, we summarized and condensed this information to provide you with the bottom line.

EDITOR'S TIP: Combine Thyroid T3 with a proven fat burner such as Leptigen for better results.

What You Need To Know

Thyroid T3 is a diet supplement that should be taken 2-3 times daily (two capsules is a serving). According to the company website, this product helps boost metabolism and increase thyroid output. It’s directed to be used in conjunction with a reduced calorie diet plan. When taken as directed, Thyroid T3 is supposed to help you “shed hard to lose pounds” at a faster rate. While this product does not contain any stimulants, it does contain; Gum Guggul Extract (300mg), L-Tyrosine (300mg), Garcinia Cambogia (200mg), Dipotassium Phosphate (150mg), Sodium Phosphate (75mg), Disodium Phosphate (75mg) and Phosphatidyl Choline (25mg).

Thyroid T3 is made by Absolute Nutrition, a company that was founded in 2006. This product can be acquired from the website for $39.50 (180 capsules) and it does contain some herbal ingredients, but read on…

Side Effects – A Concern?

“After reading all sorts of customer feedback for Thyroid T3, it’s clear that this supplement can lead to some adverse effects. This should not be taken lightly, and you should be especially careful if you have an existing health condition,” says our Research Editor.

One customer stated, “My wife is on T3 at this time. Her heart rate is going up, also with her blood pressure.”

“I started taking T3 and I am very sleepy and cannot think clearly,” said another user.

Lack of Real Results

There are no published weight loss results for Thyroid T3. This is a red flag. In fact, one customer complained, “This is totally a fluke, It has no hormone T3 whatsoever, therefore it does not help on loosing any weight.”

Another user said, “Don’t waste your money like I did. I have to write more words for them to post this review. Stupid, stupid.”

Our research has revealed that if there is a certain part of a diet supplement or program that is especially burdensome (side effects, lack of real results, high cost) the chances of real weight loss success are not good. In other words, if Thyroid T3 does cause side effects and fail to produce real results in a lot of people, this could be problematic.

The Science – Solid?

From what we gathered on the official website, there is no solid clinical research that supports Thyroid T3. Naturally this is concerning. For us at DietSpotlight, we need to see documented scientific studies that support the product’s weight loss claims.

The Bottom Line: Does Thyroid T3 Work?

Now the moment you’ve been waiting for: our bottom line on Thyroid T3. Well, we like Thyroid T3’s longevity as a product and some positive comments we saw about it online. Then again, we have some concerns about this supplement because it’s not backed by clinical studies. Moreover, we’re leery about the side effects and user complaints regarding no weight loss results.

If you’d like to get rid of more pounds, then we recommend you find a diet supplement that is supported by positive feedback, does not cause harsh side effects and is backed by real science.

Among the best products we’ve seen in 2015 is one called Leptigen. Its formula is a blend four unique ingredients, which have been proven in published scientific research to help improve fat loss and elevate metabolism. You should also be aware that we can’t find any talk of harmful side effects and customer comments posted online express people are seeing solid results.

The makers of Leptigen are so positive about their product they’re offering a Special Trial Offer, which is a good sign.

Thyroid T3 is the hormone that causes the metabolism to work properly. Without it, a patient can gain weight, be very sensitive to temperature, be very tired most of the time, be depressed, and have other effects, such as dry skin. These effects can also come from having a low level of T3, something that can go unnoticed except for the symptoms. Generally the condition is known as hypothyroidism. The usual treatment for a low T3 level is to take more T3, usually under a doctor's direction. There is both a synthetic form of T3 and a natural form that are available. Someone who has the symptoms of a low T3 level should see a physician to have medical testing done.

List of Ingredients

Product Features

Depending on the patient's condition, T3 can be obtained both over the counter and by prescription, though the natural version can only be obtained by prescription. Those who do have a low level of T3 have reported much improvement after beginning to take T3. The result is generally a better quality of life because the patient feels so much better. Weight loss can result from treatment with T3, because the metabolism is then working at a normal pace instead of being sluggish.

If there are side effects, they would most likely be related to hyperthyroidism, a condition in which the thyroid is running too fast, and the metabolism speeds up. Patients with this condition lose weight rapidly and often have an unpleasantly fast heart rate. Despite the weight loss, this condition is dangerous because it is harder on the heart and draining on the body. There is also a certain diet aid known as San T3, which is not the thyroid hormone, despite the misleading name. Patients who do need thyroid treatment should be careful when encountering such products, because they are not a replacement for the natural hormone.

One of the good outcomes of taking T3 is weight loss, though the hormone should not be used with the intent of weight loss. It is essential for a properly functioning thyroid and should be used as such. The effect of taking it means a better quality of life for those who have hypothyroidism and it should not be taken by those who have a healthy thyroid.

    For everyone who is having symptoms and their blood work looks normal take a look at Wilson temp syndrome. Also, I am on a compounded T3 regiment taken 12hrs to the min. I have to check my pulse and temp and chart it. I just started. I have had horrible menses with unbearable bleeding constantly cold and on a 900-1000 cal diet with exercise with little results. I hope this helps..don’t give up AND REMEMBER YOU KNOW WHEN SOMETHING IS WRONG WITH YOUR BODY.If you Dr. will not listen kindly tell him/her to f*@k off and remove the wax in their ears, there are great doctors out there.

    I recently had a TSH test…everything was normal except T3 was 74. Is that bad?? Also, what should the normal T3 be?? Thanks for any advice you can give me.

    Just had my second thyroid test. TSH went from 4.68 to .567. Total T3 reading is 2.6. My Dr. says everything is ok. I say I need a new Dr.as I feel sluggish, keep gaining weight and cold all the time. What is your opinion?



    only free t3 on a test will show how much of the metabolic hormone you have in your body…tsh, free t4 and free t3 should always be ordered to see the full picture of how the thyroid is responding to medication and also taken in account symptoms
