What is Cytomel?

First off, Cytomel is actually a prescription medication for treating hyperthyroidism or underactive thyroid. Ingredients include liothyronine sodium. It basically helps by providing the thyroid hormone. This in turn may help reduce symptoms such as weight gain, low energy levels, hair loss and dry skin. Typically, this drug is directed to be taken once daily along with food. However, you should always follow your doctor’s instructions regarding dosage.

While we are not sure when Cytomel was first released, the active ingredient in this drug (liothyronine sodium) was approved by the FDA back in 1956. This medication is regulated by licensed professionals. Therefore your health insurance coverage may help you pay for it. Also, there are some helpful user comments posted online, but read on…

Side Effects – “Is It Safe?”

The first concern we have is Cytomel side effects. According to our Research Editor, “This prescription medication can cause unpleasant adverse reactions such as temporary hair loss, headache, increased sweating, diarrhea, irritability, tremors, nervousness, insomnia and nausea.”

One user stated, “I began having tremors, heart palpitations and tachycardia. It was a terrifying experience. My symptoms almost entirely went away when going off this medication.”

However, a different person posted, “Seems okay thus far. No Cytomel adverse reactions. We’ll see.”

Another commented, “Just started taking this. A little nauseated, but nothing major.”

User Complaints – “Yikes”

Another issue is user complaints. For example, one person reported, “Initially I was very happy with this medication. However, I am in my early 50’s and have just cracked two vertebrae and it is very painful. I also have three cracked teeth out of nowhere. This medication is the suspected problem and osteoporosis is listed as a possible side effect.”

But, a different user said this, “I have been on this for a day and my aches and pains have subsided some.”

“I have no problem taking Cytomel, and hope to see some results soon,” revealed another.

Our research has revealed that if there’s some particular aspect of a diet medication or weight-loss product that is quite bothersome or difficult (side effects, user complaints, high cost) the chances of real success for the long term are not good. So, if Cytomel does in fact cause adverse reactions in numerous users, this could be a deal breaker.

The Science – “Solid?”

We did find some clinical studies that do support the effects of Cytomel on the thyroid gland. This prescription drug essentially helps with thyroid productivity in some users. That is, if you can handle the long list of side effects that may occur.

What Users Are Saying

"”I’ve been on this for about two weeks now (taking it first thing in the morning, and then again before bed), but I noticed a dramatic improvement in my energy level in about three days. I began to wake up, feeling rested, before my alarm would go off.”"

"”Started taking product but was told by Endocrinologist to stop taking”"

"”No noticeable difference with my hypothyroidism, I went back on medication cause this did not work for it.”"

The Bottom Line – Does Cytomel Work?

Okay, now the moment you’ve been waiting for. This is our bottom line on Cytomel. Well, we like that this prescription drug is regulated by the FDA and it has been clinically tested. On the other hand, we have some reservations about this hyperthyroidism medication because it can cause a long list of unpleasant side effects. Also, we’re a little concerned about the discouraging user comments we found posted online.

If your primary goal is to shed some pounds, then we suggest you go with a product that does not cause any unwanted adverse effects, is easy to use anywhere and is supported by plenty of encouraging user comments.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement contains a proprietary blend of four key ingredients, which have been clinically tested and are shown to help accelerate fat loss and boost metabolism. We can’t find any negative user remarks online, and comments around the web reveal people are seeing wonderful results.

The makers of Dietspotlight Burn are so positive about their product they’re offering a Special Trial Offer, which is uncommon.

What You Should Know

When you begin to lose weight it can seem like everything is spiraling out of control. You may want to restrict your diet but find yourself without the energy or resources to do so. On the other hand you may feel as though you are doing everything right including eating healthy foods and exercising on a regular basis. If you are doing everything right you may begin to wonder why in the world you are gaining rather than losing weight. Sometimes being overweight is not a result for poor dietary and exercise habits. Occasionally, the cause is due to a deficiency in the body such as when the thyroid gland is not producing the right amounts of the thyroid hormone which can lead to all sorts of physiological problems, including excessive weight gain.

List of Ingredients

Liothyronine sodium.

Product Features

Cytomel should be taken by mouth, either with or without food, at the same time every day. The primary purpose of the medication is to relieve the symptoms of a thyroid gland that is not producing an adequate supply of the thyroid hormone. Symptoms this product may relieve include decreased energy, weight gain, dry skin, hair loss, heightened sensitivity to cold, and a reduction in the speed of speech.


  • This product has been scientifically shown to help regulate thyroid productivity.
  • Cytomel may be covered by insurance because it is prescribed by a doctor for a non-weight related issue.


  • Serious side effects such as nausea, irritability, increased appetite, temporary hair loss, headache, and upset stomach are associated with the medication.
  • This product can interfere with the body's ability to absorb other medications.
  • Cytomel is only available by prescription.
  • This product is not manufactured specifically for weight loss.


For some people who are overweight, a thyroid problem is to blame. For those people Cytomel may be an effective method of regulating their thyroid and may allow them to lose the weight the thyroid problem caused them to gain. For those whose weight problems do not stem from a malfunctioning thyroid, using Cytomel will not only fail to be effective; it could pose significant health risks. For the majority of dieters, this is not a product that will be an effective weight loss supplement, simply because their weight loss was not the result of a thyroid problem. If you are concerned that your weight gain could be the result of a thyroid problem, you should certainly consult your physician. If you find that your thyroid is working properly, however, consider diet supplement that has been tested and proven to be an effective way to lose weight.
