Further in this post, you will also come across Actalin’s side effects, its pros and cons, and not to mention its consumer reviews.

What Is Actalin Thyroid Supplement?

Actalin is a thyroid health supplement designed by Medix Select to improve thyroid function immunity and adrenal health. 

The thyroid supplement Actalin mostly contains minerals, vitamins, and natural extracts in its formula.  Here is some claim Medix Select makes for Actalin, it supports: 

  • Thyroid function and health
  • Immune health
  • Energy metabolism
  • Adrenal health

With Actalin you expect optimal adrenal, thyroid, and immune system health. The supplement also has an ample amount of iodine in it. 

Iodine is a mineral that is critical for the production of thyroid hormone and your body doesn’t make iodine by itself. So, it must be fulfilled by your diet.

You can think of choosing Actalin if you feel your thyroid function isn’t optimal. It may help restore the healthy function of your thyroid.

Actalin Manufacturer

Dr. David Brownstein who is a board-certified family physician holds the credit for creating Actalin. He is also a writer of several health books and Medical Director of the Center for Holistic Medicine.

The combination of 17 components in Actalin is seen to restore optimal thyroid levels in most people. 

The manufacturing part of Actalin is carried out by Medix Select which designs several dietary supplements with a holistic approach. Medix Select has supplements for Digestion, Immune health, heart health, memory health, men’s health, and many more conditions.

Thyroid Health: Why It Is Important?

Well, Actalin’s primary claim revolves around improving your thyroid health and restoring its function. So you must know, what is thyroid health and why it is so important.

The thyroid is an endocrine gland present in your neck region having the shape of a butterfly. It secretes the thyroid hormone, thyroxine, which is responsible for the steady growth and development of your body.

The thyroid gland is responsible for maintaining metabolic rate, bone and brain development, and heart and muscle functions. 

But most people in the US or outside it face thyroid disorders and suffer from sub-optimal thyroid health. The symptoms of poor thyroid function include:

  • Weight gain without any reason.
  • Feeling low on energy most of the time.
  • Fatigue and low mood.
  • Increased sensitivity to cold.

The above symptoms are mostly a result of poor metabolism. 

The two common conditions due to a suboptimal thyroid are Hypothyroidism and Hyperthyroidism.

Hypothyroidism is a condition in which your body is unable to produce enough thyroid hormone. The diminished thyroid level makes your metabolism sluggish.

The food you eat doesn’t get converted into energy as efficiently as it should. The underactive thyroid leads to constipation, fatigue, unnecessary weight gain, and deprived energy levels.

While hypothyroidism is the most common thyroid condition, some people also face hyperthyroidism. During hyperthyroidism, your thyroid gland gets overactive and produces a higher level of thyroid hormone than usual.

Increased thyroid hormone level leads to increased metabolism, rapid heartbeat, unintentional weight loss, and increased appetite.

Hypothyroidism is also a result of a high TSH (thyroid-stimulating hormone) level while during hyperthyroidism your TSH level falls.

Thus having an optimal thyroid function is very important for overall well-being. Actalin thyroid supplement is mainly designed for this function i.e. restoring your thyroid health.

How Does Actalin Actually Work?

The combination of herbs, vitamins, and minerals helps actalin promote the conversion of T4 hormones to T3. This can lead increase in the level of thyroid hormones in people with poor thyroid function.

Actalin also has a sufficient level of iodine in it. The deficiency of iodine is also a leading cause of hypothyroidism. 

Some ingredients in Actalin Actalin seem to impact your thyroid function and health positively. However, the working of this formula hasn’t been elucidated by the manufacturer in its official shop.

Proposed Benefits Of Actalin 

As discussed above the Actalin dietary supplement contains a strategic blend of 17 nutrients and a proprietary blend of 5 Ingredients within its formula. 

Let’s take a closer look at what benefits Actalin nutrients and ingredients provide you:

  • Helps to increase energy metabolism.
  • Improve your immune health.
  • Supports thyroid functions and Adrenal health.
  • This supplement also helps in fighting free radicals.
  • It May support circulatory system health.

The above-claimed benefits by Medixselect on their Actalin supplement have a shred of strong evidence based on the available research that it supports thyroid function with the inclusion of ingredients such as:

Ashwagandha extract, Kelp, and Potassium Iodide, Magnesium Gluconate, Copper Picolinate, and L-selenomethionine.

Actalin Ingredients

For a thyroid supplement, like Actalin or any other to work, its ingredients composition must be strong. 

Besides the effectiveness, a review of Actalin ingredients is also an insight into its safety.

A majority part of Actalin ingredients are covered by a proprietary blend. However, it also contains different Vitamins, Mineral, and a non-essential amino acid, L-tyrosine.

Actalin Ingredients: Vitamin A, Vitamin D, Vitamin E, Riboflavin, Niacin, Iodine, Magnesium, Zinc, Selenium, Copper, Manganese, L-Tyrosine, Methylsulfonylmethane, and L-Tyrosine.

The serving size of Actalin is two capsules at a time and each container has 30 servings. 

Well, these were the ingredients each capsule of Actalin contains. But, there’s something more to know. Here’s a brief discussion on each ingredient and its science.

1. Iodine (from Kelp and Potassium Iodide), 200mcg

As you must know Iodine is the most critical element for thyroid hormone production. Your body cannot make iodine, thus it must be sourced externally from the diet. 

Actalin contains 200mcg of Iodine in its thyroid supplement. A healthy adult needs 140mcg of iodine per day. So, actalin carries sufficient iodine to fulfill your body’s iodine requirement.

Iodine deficiency in adults isn’t limited to hypothyroidism and goiter. Its implications also include impaired mental function, miscarriage, and stillbirths.

2. Vitamin A (as Retinyl Palmitate), 750mcg

A higher level of TSH is the main indicator of hypothyroidism, a decrease in thyroid hormone levels. Vitamin A was successful at reducing TSH concentration during a 2012 study.

Vitamin A in Actalin also plays an important role in activating thyroid hormone receptors and regulating thyroid hormone metabolism.

3. Vitamin D (as Cholecalciferol), 7.5mcg

The role of Vitamin D in healthy bones and muscles can’t be overlooked. Besides regulating the calcium and phosphate in your body, patients with hypothyroidism are also advised to have Vitamin D supplementation.

As, during the study, hypothyroid patients also suffered from 

D (deficiency of Vitamin D). Thus, Vitamin D presence also benefits Actalin users with thyroid health.

4. Vitamin E (as D-Alpha Tocopherol), 67mg

Another Vitamin needed for optimal thyroid function is Vitamin E. It has antioxidant properties that help oxidative stress caused during hypothyroid.

During a 2013 study, patients with hypothyroidism showed an improvement in their cognitive deficit when they were given Vitamin E supplementation.

5. Riboflavin, 5mg

Vitamin B2, commonly known as riboflavin is also known for calming the root cause of autoimmune disorders like Hashimoto’s. It is a condition in which your immune system starts creating antibodies damaging your thyroid gland.

Overall, Vitamin B has an important role in thyroid function and hormone regulation.

6. Niacin (as Niacinamide), 30mg

Niacin is another type of Vitamin B that maintains the health of your skin, nervous system, and digestive system.

For people with hyperthyroid conditions, Vitamin B3 supplementation may decrease thyroid hormone levels. Thus, actalin may be beneficial for cases of hyperthyroid too.

7. Magnesium (as Magnesium Gluconate), 15mg

It is one of the important minerals that help your thyroid gland produce T4 hormones. Also, low levels of magnesium have been associated with risks of hypothyroidism.

8. Zinc (as Zinc Picolinate), 5mg

The role of zinc in your body’s growth, metabolism, and immune system is something every one of us knows. It is one of the most abundant and nutritionally essential minerals in the human body.

Zinc is also essential for the production of T3 from T4 hormones in thyroid glands.  A 2007 study also found Zinc supplementation to provide a favorable effect on total T3 hormone levels.

Overall zinc’s presence in Actalin may show positive results on thyroid hormone levels.

9. Selenium (as L-Selenomethionine), 30mcg

Your body produces oxygen-free radicals during the production of thyroid hormones. Selenium acts as an antioxidant by removing these oxygen-free radicals in the thyroid.

The fact that selenium concentration in your thyroid is higher than any other part also indicates it is needed for optimal thyroid function.

10. Copper (as Copper Picolinate), 0.1mg

It is another mineral needed by your body to form red blood cell formation and maintain blood vessel health.

Copper is also known to stimulate the production of the T4 hormone or thyroxine and prevent its over-absorption by your body cells.

11. Manganese (as Manganese Gluconate), 2mg

Studies find the role of manganese in thyroid homeostasis as well as a function is still not elucidated. However, some convincing evidence finds manganese to affect thyroid function by regulating deiodinase enzymes.

12. L-Tyrosine, 300mg

As mentioned, Actalin also has a non-essential amino acid, L-tyrosine. It is the second major ingredient after the proprietary blend in actalin.

Some of its important role in your body includes protein building and the production of thyroid hormones and some enzymes. 

A 2015 study suggests a reduction in the level of tyrosine is associated with a disturbance in thyroid hormone levels. However, the result warranted further investigation.

13. Methylsulfonylmethane, 50mg

MSM, short for Methylsulfonylmethane, is an organosulfur compound popular for reducing joint pain and inflammation.

Also, 50mg of Methylsulfonylmethane intake per day helps maintain healthy thyroid function.

14. Proprietary Blend, 540mg

Besides all the other ingredients, Medix Select Actalin contains a proprietary blend of 4 natural and animal-extracted compounds. 

Each serving contains a 540 mg proprietary blend. However, one con of a proprietary blend is you don’t get the information on the dose of each specific ingredient.

The proprietary blend contains: 

  1. Guggul Gum resin extract: It is an Indian Ayurvedic herb that may help thyroid function. It can help hypothyroidism by improving iodine intake.
  2. Ashwagandha Root Extract: It is a popular adaptogenic herb again of Indian origin known for reducing mental and physical stress. Moreover, it can help Actalin improve thyroid hormone levels too.
  3. Forskhlii Root Extract: This extract can help increase the production of T3 and T4 hormones by your thyroid. 
  4. Adrenal Glandular (Bovine) Powder: It is made from the adrenal glands of slaughtered cows. It has a variety of nutrients, hormones, and cofactors.  Its role in thyroid function is still not evaluated. But, it may support your adrenal health.

Conclusion On Actalin Ingredients

While having a review of Actalin ingredients, we found it contained some science-backed ingredients to help thyroid function. 

But for hyperthyroidism or overactive thyroid, Actalin might not be effective. Short-term supplementation of Actalin may help individuals with iodine deficiency. 

While most ingredients were safe, some had higher concentrations in Actalin. Also, many ingredients lacked solid evidence for restoring thyroid health.

Actalin Side Effects You Must Know

Actalin contains several ingredients in its formula which can help to support thyroid functions but on the flip side, it can also lead to cause various effects.

Because there is no mention of exactly the ingredients formations in the supplement and how much thyroid hormone it contains.

Although the manufacturer does state it is an all-natural premium dietary supplement and does not mention any side effects related to the supplement. 

But besides their claims of an “ all-natural premium dietary supplement”, this doesn’t mean that it’s completely or substantially free from any effects. It does contain some active ingredients which can cause side effects and there are some users who reported the side effects.

Below are some side effects customers have reported after long usage of the Actalin supplement:

  • Nausea and diarrhea.
  • Headache and shortness of breath.
  • Blacked out and had morning jitters.
  • Loss of consciousness.
  • Gastric upset and chills.

The recommended daily intake of iodine is 150mcg per day for most adults and intake is higher for pregnant women or nursing mothers.

Actalin supplement contains an Iodine (from Kelp and Potassium Iodide), 200mcg as an active ingredient, and consuming too much iodine can result in fatigue, and weight gain and increases the risks of cardiovascular disease.

Another ingredient in actalin supplements is MSM and excess ingestions of MSM in some might cause stomach discomfort, bloating, diarrhea, and nausea.

My neck size has gone down about a 1/4 to 1/2 inch. Overall feel more energic. Cannot say it is the Supplement per serving but … happened after I started tacking them”

Ameen S. says

“It”s satisfactory in its daily use”

Alarie says

“I have received them and I tried them but did not see the result”

Marrie Harrington says

“I understood the word “supplement” to mean “extra help.” However, I am/was already on thyroid medicine and after taking these two weeks, I was very short of breath and going into afib. My doctor said it is because taking a supplement with iodine in it, when I was already getting iodine in my medicine was causing me to go from hypo to hyper. I did not see this anywhere on the description as a warning. I got 3 more bottles in the mail two days ago and hope I can figure out how to stop them from coming automatically. It is probably okay if you are not already on thyroid medicine”

Actalin Review: The Bottom Line

Now, it’s time to decide, Does Actalin work, and worth your money? Well, there were consumers who had a positive experience taking Actalin, but the number of consumers for whom it didn’t work was no less.

Coming to the effectiveness of this thyroid supplement, Actalin could be a safe and effective alternative for an underactive thyroid. However, it is more for overall well-being than a thyroid function booster.

In case you want it to take for an energy boost, metabolism, and immunity, it is a decent choice. 

But, if you are thinking of dealing with your thyroid problem with this stuff, seeking a doctor’s help is a must. And, there might be some better and more effective alternatives to Actalin for this purpose.

While many saw the results, shortness of breath, headache, and stomach issues were a few common side effects of long-term use.

Also, Actalin has higher doses of some ingredients, so make sure you are not taking any medication along with actalin. Doing this might lead to some serious conditions.
