It’s time to review Actalin Thyroid Supplement – which makes a very promising thyroid supplement.

So do you think it works for real?.

At first sight, I would say it has both positives and negatives:

  • a lot of side effects
  • good formula
  • easy to take

Well, I studied the different aspects of this supplement to find out the truth behind it.

Note: This review is based on my opinion + research on Actalin.

What I Didn’t Like About It

  • Causes some severe side effects
  • It's pretty slow for a lot of people
  • Formula can be too strong in some cases



Actalin In A Nutshell

Overall – Actalin is a decent thyroid supplement.

It has a very good set of ingredients, unlike many other products.

However – I found some little issues about it:

  • doses can be very strong for some users' tolerance
  • formula can cause some serious side effects
  • in some cases, it tends to work slow

The major issues of previous buyers are its adverse reactions.

I'm not saying that they appear in all cases.

But it's always better to be informed.

So if you want to be completely sure, check the list of ingredients first or consult a doctor.

Now – Actalin is quite easy to take, since it only requires 2 capsules/day.

A bottle of 60 capsules costs $39.95 (which will definitely last a month).

So if you have the necessary budget, it's up to you if want to try it out.

Overall – Actalin is a good product.

But I strongly believe that there's a better alternative that is safer to use.



#1 – Claims & Producer

Let's start with some basic info about Actalin:

  • how it works
  • what issues it treats
  • the company behind it
1. Claims

Actalin's main goal is to fight that “butterfly effect”. 

What exactly does this mean?

Based on its website, the “butterfly effect” is be the reason behind several issues:

  • low energy
  • moodiness
  • not feeling quite right

The “butterfly gland” is another term for thyroid, which is responsible for body functions.

So when it's not properly taken care of, your whole body will be affected.

Now – the creator of the product claims to address thyroid-related problems.

Here are the promises of Actalin:

  • improves thyroid function
  • boosts energy and metabolism
  • helps with adrenal, circulatory and immune health
  • prevents free radical damage

Also – it claims to be strategically formulated to promote an optimal thyroid health.

Overall – the product seems to be promising.

But let's see if it really lives up to its promises.

2. Producer

The company behind this supplement is Medix Health.

So far – it has a very informative website:

  • produces supplements for various issues
  • contact info includes a phone number and contact page

I also searched for the brand alone and I didn't see any complaints so far.

Its products have positive reviews and they are praised by many people.

So overall – I would say that it's safe to buy from this brand.



#2 – Ingredients (9 out of 10)

Honestly – Actalin has a very promising formula:

  • vitamins and minerals
  • thyroid helpers
  • herbal extracts

Unlike other thyroid supplements, Actalin has 3 categories of its ingredients.

Besides, they are extremely varied and versatile.

That's surely a good sign when it comes to its claims and promises.

Now – lets a look at all the ingredients present and their benefits.

1. Vitamins & Minerals

Actalin Thyroid Supplement is mostly composed of essential nutrients and vitamins.

So if you're curious about what they can do, here are some of their benefits:

  1. Vitamin A – regulates thyroid hormone metabolism
  2. Riboflavin – lowers factors leading to stress [1]
  3. Niacin – boosts brain functions
  4. Vitamin D – prevents possible thyroid diseases [2]
  5. Magnesium – supports thyroid's proper function
  6. Zinc – helps to convert T4 and T3 hormones [3]
  7. Vitamine E – decreases possible sources of stress [4]
  8. Selenium – provides antioxidants to protect thyroid health
  9. Copper – maximizes hormone absorption [5]
  10. Manganese – balances thyroid enzymes

If you ask me, these compounds are known to help the thyroid.

It's true that they're not a life changer, but they have some real benefits.

So incorporating them into this supplement is a very good idea.

2. Thyroid Helpers

Now – a thyroid supplement should also have some classic thyroid compounds.

In this case, these are the ingredients present:

  1. Iodine – helps regulate thyroid function [6]
  2. L-Tyrosine – balances the production of thyroid hormones [7]

If you ask me, a good thyroid supplement should contain at least one thyroid helper.

Actalin fits in this criteria, so it's perfect.

3. Herbal Extracts

Actalin is also composed of herbal ingredients.

However – its herbs come in a mix/proprietary blend:

  1. Guggul Gum Resin Extract – improves thyroid enzyme activity [8]
  2. Ashwagandha Root Extract – stimulates endocrine system [9]
  3. Forskohlii  Root Extract – supports the secretion of thyroid hormones

In my view, herbal extracts are always a good addition to a supplement.

However, they are probably in some very small doses.

That's because brands tend to use proprietary blends to hide the low doses of certain compounds.

4. Other Ingredients

Lastly, these are added ingredients present in Actalin:

  1. Adrenal Glandular (Bovine) Powder – helps combat fatigue and stress [10]
  2. Methylsulfonylmethane (MSM) – reduces joint pain and inflammation [11]

In my view, these compounds are more helpful for general health functions.

But even so, they surely don't do any harm in Actalin, on the contrary.


Overall – I think Actalin's formula is impressive.

Although it's not my personal favorite, I have to say that it's a very good one.



#3 – Pills & Dosage (8 out of 10)

Firstly – here are some details about Actalin in this chapter.

1. Pills

Let me quickly describe you the product's consistency:

  • light brown/green color
  • normal pill size
  • slight herbal scent

If you're used to taking medicines, these pills won't be a big deal for you.

Overall – Actalin looks like a typical supplement, in my view, there isn't anything special about its capsules.

2. Dosage

Based on its instructions, Actalin is quite easy to take.

You only need 2 capsules per day (preferably with a meal).

However, the dosage also depends on your doctor (if you're seeing one).

Now – the low number of pills/serving of Actalin is a good sign.

So if you're not a fan of capsules, this dosage is still on the decent size.



#4 – Results (6 out of 10)

Now – Actalin looks very promising.

So I checked out its authentic reviews to see how it works.

The goal is to give different perspectives about the product.

Also – I want to avoid giving you a biased or one-sided view.

Note: I only analyzed authentic reviews, not promotional or fake ones.

1. Positive Opinions

Besides the official website, Actalin is also available on Amazon.

Out of all the reviews, here are what most people comment about it:

  1. A lot of reviews were about thyroid improvement.
  2. Others noticed their thyroid or neck size went back to normal.
  3. Some said that it helped their metabolism and mood.
  4. The rest mentioned the noticeable increase in their energy.

The overall rating of this product is 3.9/5 stars.

Honestly – I expected a higher rating, considering all of its great features.

So I have to admit I was pretty disappointed by its overall reviews.

But one thing is for sure – I can tell you that it's not a scam.

2. Negative Opinions

Meanwhile – here are the complaints of some previous buyers:

  1. Most of the users said that they experienced alarming side effects.
  2. Others mentioned that it didn't do anything for their thyroid problems.
  3. Some said that it's just a waste of money and they would not recommend it.
  4. There are few who didn't see any results at all.

Now – a product's effect is very selective and it depends from person to person.

And Actalin doesn't seem to be too bad in terms of results.

Still, it's not amazing either (or not as much as I expected).

However – the most common complaint about it are its side effects.


Overall – Actalin doesn't really have a lot of reviews behind.

But at least some of them look very authentic. 

Overall – it looks like some buyers liked how it works, while others didn't.

However, I believe there's an alternative with more reviews to prove its effect.




#5 – Side Effects (4 out of 10)

Again – there are some complaints about the supplement's adverse effects.

So here are the side effects others experienced with Actalin:

  • short of breath
  • chills
  • blacked out
  • morning jitters
  • lost of consciousness

Now – I'm not saying that issues will appear in all cases.

However, they seem to be a lot more common than in similar products.

So you should keep this in mind – if you're planning to get the product.

If you ask me, I find these side reactions quite alarming.

Even though Actalin is promising, they are too numerous.

Also – in general, thyroid supplements shouldn't cause too many side reactions.

So I suggest you to read its consider this aspect.



#6 – Price (6 out of 10)

Now – I consider Actalin's price just in the middle.

It can be pricey for some people and reasonable for others.

1. The Exact Price

Based on my careful research, Actalin is available on Amazon.

However – you can find more discounts on its official website:

  • One month supply costs $39.95
  • 3-months supply costs $29.96/bottle
  • 3-months supply + smart ship costs $26.64/bottle

I want to clarify that “Smart Ship” is just another term for  subscription.

It will automatically place you another order before the 3rd month ends.

Now – in a one-month supply, you will get 60 capsules.

Again, the recommended dose is 2 capsules daily, so a bottle will last a month.

If you ask me, I have a mix feeling about the price.

In terms of the formulation, it's a good deal for the money.

But regarding the side effects, it's not a good price at all.

Overall – it's up to you if you want to try Actalin or not.

2. Competitors’ Price

I have a good alternative that is much better, in my view.

The product is called Thyroid 911 and it's my top recommended thyroid supplement:

  1. Thyroid 911 contains a mix of essential ingredients for thyroid.
  2. The formula focuses on improving overall thyroid health.
  3. Actalin also has a good set of ingredients for thyroid.
  4. But its formulation can be too strong for others (it causes side effects).
  5. Both supplements require 2 capsules daily.
  6. Thyroid 911 normally costs $69.95 but can be bought for only $39.
  7. Actalin costs $39.95 for a monthly supply and offers discounts for larger quantities.

Now, both products are almost in the same price range.

But in my view, Thyroid 911 is the better option.

My explanation is that it causes minimal to no side effects at all.

So you're staying on the safer side if you agree to go for it.


For its quality, Actalin has a reasonable price.

A month's supply will definitely last a month and you will get discounts for buying more.

Still, the choice is all yours.




#7 – Final Conclusions

Now – here’s the summary of my thoughts about Actalin.

1. Good Formulation

Right away, I want to say that Actalin has some very promising ingredients:

  • vitamins and minerals
  • thyroid helpers
  • herbal extracts

Honestly – it's way better compared to other thyroid supplements.

So overall – I think it should be effective for most people.

2. Regular Side Effects

Although Actalin has a good formula, it can be too strong for some people.

There were people who complained about alarming side effects.

However – there were also previous buyers who didn't see any results at all.

So in my view, the effect is selective – but you should still be aware of the possible side reactions.

3. Reasonable Price

Actalin has a decent price for its features:

  • a good set of ingredients
  • 2 capsules/day
  • one bottle lasts a month

So if you don't mind the price of $39.95/month, it's great for you.

But it can be pricey for people who are on a tighter budget.



My Verdict – Worth It Or Not?

Short answer: Yes and no – because I have mixed thoughts about it:

  1. Price is very reasonable
  2. Can cause some severe side effects
  3. Has a good set of ingredients
  4. Works pretty slowly in many cases

Overall – Actalin Thyroid Supplement is actually a decent product.

But it can also trigger some alarming side effects.

So if you really want to try it out and be sure, I recommend you consult a doctor first.

That especially if you have some actual thyroid problems.

It's essential to have the right treatment prescribed to you (than taking a supplement on your own).

Now – I know an alternative to Actalin that you might want to try.

It's my #1 recommend thyroid supplement.

The product I'm talking about is Thyroid 911:

  • Contains some essential thyroid ingredients
  • Has minimal to no chances of causing side effects
  • Quite easy to take on a daily basis
  • Works pretty fast and really well

In my view – Thyroid 911 is still the better thyroid supplement option.

It's proven to be effective and safer for your health.

So you will definitely get your desired results with no side effects.

12 thoughts on “My Review: Actalin Thyroid Supplement (2024) – Are The Side Effects Real?

  1. Thank you for the information. My naturopath doctor prescribed levothyroxine 50mg and I understand it has some serious side efffects: loss of hair,and others, The reason she wants me to take levothyroxine, is to get my T4 levels back to normal. Would any of the products you mention Acatlin or Thyroid 911 do the same thing??
    I did discuss taking Acatlin but after reading your comparison I should think about the Thyroid 911.

    1. Hi Judit, sorry to hear about your thyroid issues. I personally would advise you to give levothyroxine a try because its side effects are not as scary as they sound (a very small per cent of people actually experience them). If you start dealing with some side effects for real, then you may want to try some alternatives. But I would never recommend using a supplement instead of a prescription treatment, no matter how free of side effects it would seem. That’s because supplements don’t have the same potency and they tend to work a lot slower. So I really don’t advise you to switch to a supplement just for this reason. Better try levothyroxine, see how it goes and get back to me with your feedback. That’s surely what I would do if I were you.

  2. I heard about this first from my coworker. She’s my fellow janitor colleague and frankly, we don’t really earn enough to purchase supplemental products because the necessities already take too much of our finances. Her suggestion was really something that I did not expect because you know, it came at a time where I needed it the most. True enough, I found it here in your blog and it has a high rating. Now, I can see that it’s not all rainbows and butterflies but it’s a risk that I’m willing to take. I’m just so glad that I found this articles of yours and so, thank you very very much.

    1. Hi Vienna! Thank you for your hard work and for being part of an important job. Actually, one of the strongest selling point of this product is it’s affordability though it does have some risks in it. I can understand why you would choose it over the other but still, given the risk, I think it would be fine to also consider Thyroid 911. It might not be the most affordable but compared to Actalin Thyroid Support, it has an overall better composition and effect little to no side effect. As such, although it has higher price, it’s better in the long run. This is just a suggestion and you can definitely choose whatever fits you.

      All the best,

  3. I am new here. I actually just found out about your page from my mother. She’s an avid fan but sadly, we just found out that she has an abnormal level of TSH. She just bunked it as tiredness but it came to a point where she had to be hospitalized. Some of our relatives suggested Actalin and so I searched about it here. Given the side effects it has, I don’t think we would want to risk it. We are not rich and we are just normal employees but we are willing to pay for our mother’s recovery, health, and safety. Do you have better suggestions?

    1. Hey Christoff, how are you doing? Thank you for giving us a chance to be of help to you. Unfortunately, despite the high rating of this product, there really is a downside on it which is its side effect. This is somehow normal for supplements designed for this but it can certainly be avoided. We actually found a much better product which is the Thyroid 911. It is potent but at the same time safer with a guaranteed effect so frankly speaking, it has overall better quality per price. Though it can be pricey, it is actually cheaper in the long run because of its efficacy. As such, I really recommend that you check it out and see for yourselves. I am really hoping for your mother’s recovery and I am sure that she appreciates all you love, effort, and support.


  4. friend, i have been looking for you. you scammed me. i suffered a lot and ended up throwing away the bottle i bought from you. i brought from amazon and experienced shortness of breath and even fainted twice during the time i was taking this. i don’t take anything else with this but i want a refund or reimbursement because i suffered a lot.

    1. Hi Yilmaz, thanks for commenting and sharing your experience. I’m sorry this happened but unfortunately, we are not in any way connected in the company nor do we retail this product. As such, we cannot do any reimbursement or refund. In fact, we are also emphasizing in our review article that it is unrecommended to buy from amazon because there are a lot of counterfeit products being sold there. I’m really really sorry as I don’t know any way to help you. What I can suggest right now it that contact the seller/retailer in the amazon where you brought the product and tell them about your experience or report them. Suing them is also an option but it may entail a lot things. Aside from that, you can also contact the legitimate company so that they themselves can take action–of course there is no guarantee that you will be reimbursed but at least, others can be saved from this scam.

      Thank you for sharing and may this be a lesson or warning to others too. Always keep safe.

      All the best,

  5. I ordered this for my wife. She’s been taking this for 3 weeks and now she is cold all the time and she is very puffy. She doesn’t have a weight issue. Her ankles and face are mostly affected.

    1. Hi Cully, I’m sorry to hear about your wife. Was she taking anything else during that period? Those symptoms are probably because of the supplement, so she should definitely try to give it up and maybe check her TSH.

      I don’t know if she’s suffering from hyperthyroidism or from a low thyroid – but those symptoms are specific for a low thyroid, so checking her TSH would be a good idea. She probably tested it out in the past (at least once), so she could compare her actual value with the last ones and see where she stands. But if her value is much higher than it was in the past, it’s clear that Actalin isn’t really helping her thyroid, on the contrary.

  6. I actually tried this product and it did a good job for me. There were certainly a result and aside from that, I did not experience side effect whatsoever. Now, I am no longer taking this product because I’m already back to my normal TSH levels. I’m sure that there is no perfect product but I would like to say that it is also okay to take risks. By the way, I’m scared that I might be losing memory because I seem to frequently forget a lot of things nowadays and to think I’m not even that old?! Do you have any recommendations for me? Please I really need it in my work as a teacher. Thank you!


    1. Hi Remy, this is Angelica! Thank you so much for giving us your feedback on this product–it means a lot to us and other readers. So glad that it worked out great because apparently, not everyone had a good experience with this product. It’s nice to know that you have recovered now. Hopefully, you are fully recovered now and won’t revert back to your previous health status. And certainly, the decision is up to the user/consumer and there are really times where it is alright and best to take risks. As for you request on how to improve memory, there are plenty of supplemental products in the market that can help you. It only depends now on your budget and needs. Aside from that, you can also follow this steps on how to improve your memory in addition to taking supplements to achieve better result. Hopefully, I am able to provide a good suggestion to you. Thanks!
