Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this was the only product to contain Fungi-Sci™ – a patented Mushroom blend containing 5 types of Mushrooms, B-Sci™ – a patented Vitamin B complex, Vitamin C to boost cortisol production, plus other clinically-proven ingredients to support adrenal health. Moreover, it includes BioPerine® for enhanced absorption and faster results. Dosage is based on clinical studies which suggests that these guys are serious about what they do. We liked that it’s served in a vegan-friendly capsule as well as offers a 60-day money back guarantee if you are not happy with the results. What have you got to lose? Nothing!

Why do we recommend Adrenasyl?

Main Benefits:

  • It contains a patented Mushroom complex, Fungi-Sci™, which contains 5 types of Mushrooms including Shiitake, Cordyceps, and Reishi, which provide adaptogenic properties and each play a different role in supporting adrenal function.
  • It contains a patented Vitamin B complex, B-Sci™, which is essential for nourishing and repairing the adrenal glands and supporting the adrenal cascade.
  • It contains Vitamin C plus a patented Bioflavonoid complex, Bio-Sci™, which includes Acerola Berry and Rosehip. Vitamin C is a powerful antioxidant and essential for the production of cortisol.

  • It contains a variety of adaptogenic herbs including Rhodiola Rosea, Ashwagandha, Schisandra Extract, Eleutherococcus Root Extract and Astragalus Extract. Adaptogens help the body cope with the effects of stress.

  • It does not contain any preservatives, artificial colorings, hormones, or unnecessary ingredients that may dilute the efficacy of the product.
  • Provides a vegan-friendly formula.
  • We found so many supportive consumer reviews from users who had experienced excellent results, some within as little as a week.
  • Its daily suggested serving is the optimal potency as recommended by doctors for effectiveness and is supported by extensive clinical research trials and studies.
  • This manufacturer’s customer service is second to none, it provides excellent support and help. Furthermore, it offers an excellent money-back guarantee if customers are not happy with their results.

This unique formula was the only one that we could find that was backed by solid clinical data and included this specific blend of ingredients in their potent doses.   


Dealing with prolonged stress can leave you feeling fatigued, moody, and unable to focus. It can also lead to numerous health conditions which can have devastating consequences. When your body is unable to cope with the stress it is faced with, your health suffers. The adrenal glands are two small glands located above your kidneys which is your control center for dealing with stress. They produce the hormones which are released into your bloodstream which help the body deal with stress, such as cortisol, as well as manage other bodily functions. However, constant stress results in the adrenal glands being overworked. If your adrenal glands are not working properly, you will feel it. You may have trouble sleeping, feel constantly exhausted and also have sugar and salt food cravings. Alongside dietary and lifestyle changes, there are many ingredients that have been linked to promoting adrenal health and helping the body better cope with stress. There are several key studies that help pinpoint the way when it comes to finding the most effective adrenal support supplement.

First and foremost, adrenal support supplements must be made using pure and natural ingredients so that they are safe for long-term use to promote health and well-being. Using anything less will compromise the quality of the product you receive.

Secondly, the inclusion of a variety of clinically-proven ingredients to support adrenal health is key. Adrenasyl contains a range of beneficial ingredients such as 3 patented trademarked blends, 5 different types of Mushrooms, a Vitamin B complex, Vitamin C plus a Bioflavonoid complex to promote absorption, and a variety of adaptogenic herbs. Not only is Adrenasyl the only product we found that contains this quantity of beneficial ingredients, but it is also the only one that has supportive clinical data backing up its formula and the ingredients it contains. Upon reviewing hundreds of similar products, we were surprised that most products don’t include many of these ingredients.

Many companies who enjoy a positive reputation, take advantage of their good standing with the public in order to sell cheap health supplements. It’s so distressing how easy it is, which is why it is incumbent on every consumer to do their own fact-finding on any health product they purchase.

Adrenasyl contains effective ingredients to promote adrenal health and help the body better cope with stress, as well as boost energy, improve sleep, and promote wellness. What we really like is that it is made by a company that consistently uses clinical studies as a benchmark for the dosage of all their health supplements. There is also a money-back guarantee which can be claimed by speaking to their customer service agents who are real, not just bots!

Additionally, you will not find any ingredients in Adrenasyl which shouldn’t be there. There are no added fillers, binders, additives or preservatives. There are so many products out there that do not fall within the realm of high standards, offering artificial alternatives and all sorts of extras inside their formulas. It is a relief to be able to recommend a company that manufactures such a unique, well-researched product.

To summarize, Adrenasyl uses top-quality natural ingredients, provides awesome results, has a caring customer support team and a great price. From what we saw, without a doubt, this is an extremely good product.

Quality Assurance

Over the last few years, we understand how consumers have grown skeptical of nutritional and health supplements. This simply comes down to shady companies providing useless formulas that contain unrelated and unuseful ingredients or that add fillers or binders to their products. Often, these ingredients are not pure, or have been tested for quality and have no scientific validity as to why they have been included in the formulas. Not only is this irresponsible, but often quite dangerous. Truth being, there is absolutely no reason why anything artificial should be added. Natural and pure is the best.

On many nutritional supplements, the label states that the ingredients are either ‘active’ or inactive’. In simple terms, the active ingredients are the reason you decided to purchase the product and the ones that actually bring you the results you are hoping for. When you see a long list of inactive ingredients, beware, often companies will fill their products with unhelpful and potentially dangerous junk.

That is why, for us, Adrenasyl is a product that does not fall within this category. Its formula contains only natural and pure ingredients backed by numerous clinical studies and research. It offers a simple philosophy that seems to work well – offer top-quality ingredients in the most effective potency, great price options with a terrific money-back guarantee and you won’t be disappointed.

Another aspect of taking supplements that contain a large amount of inactive or unnecessary ingredients is the lack of understanding of how these chemicals may affect existing medical conditions or medications. If the ingredients are bona fide and in their natural form, side effects or negative interactions are unlikely to be experienced.

We were very happy to discover that Adrenasyl is manufactured in an FDA registered facility. What’s more, is that it is cGMP recognized and complies with the US Pharmacopeia’s standards for quality and purity. This suggests that this company takes what it does very seriously, and strives to keep its products safe, natural and effective – a mentality that we totally appreciate.


Adrenasyl by Approved Science comes at an affordable price with some excellent multiple purchase deals, allowing for huge cost savings for consumers. Also, this company is staunchly against any auto-ship programs, as they can be nearly impossible to cancel.

Nowadays, consumers need to be ‘smart shoppers’, carrying out as much research as they can about what they would like to purchase, in order to avoid wasting their money. There are many options out there that charge a lot of money for inferior products that simply will not deliver the results that they promise. This is disheartening and quite frankly, a bad and dishonest practice.

Orders are shipped within 24 hours, with the exclusion of any orders placed on weekends and holidays. They are wrapped and sent in discreet packaging, with no identifying marks on the outside, unlike other companies who often have embarrassing slogans or logos. Furthermore, this company provides a 60-day risk-free money-back guarantee. If you are not 100% happy with the results, you are able to return the product and receive a full refund. That shows strong confidence in its product and we totally support that kind of guarantee.

In Conclusion

When people are searching for a good adrenal health product, they focus on the surface of the issue instead of attacking the root of the problem. The effects of stress on the body is a result of the adrenal glands not working at their optimal level. 

Adrenasyl specifically contains the optimal blend of ingredients which are clinically proven to improve adrenal function and help your body deal with stress in order to promote health and well-being. They are:

  • Fungi-Sci™, a blend of 5 different types of Mushrooms to support adrenal function.
  • B-Sci™. a Vitamin B complex essential for supporting the adrenal cascade.
  • Vitamin C which is necessary for the production of cortisol.
  • Bio-Sci™, a Bioflavonoid complex to enhance the absorption of Vitamin C.
  • 5 powerful adaptogenic herbs to help the body cope with stress.
  • BioPerine® which increases the absorption of the active ingredients for proven efficacy.

Additionally, there are other significant elements to bear in mind, such as third-party testing and comprehensive customer reviews that give us a great indication of how the product really works.

Of all the products that we reviewed, across all parameters, none compared to Adrenasyl. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution to improving adrenal health in order to promote well-being, you would be hard pushed to find anything better than Adrenasyl.

Read on to see what their happy customers are saying

“My Type A personality means that stress is no stranger to me. I have lived many years of my life in a state of stress and didn’t really know what it was doing to my body until I was rushed to the Emergency room with a suspected heart attack. I knew I had to do a 360 on how I was living because it would be the end of me. I made many changes and as part of my new way of living. I visited a naturopath who told me (after looking at the wobbly edges on my tongue!) I had serious adrenal fatigue. The fight/flight response had taken its toll. She suggested many vitamins and herbs to help support my body naturally and showed me a product that contained all I needed. Enter Approved Science Adrenasyl. It took a few months but after that time, I felt a renewed energy and buzz back in my life.  I didn’t realize how important adrenal health was until I didn’t have it. I would recommend this product for anyone who runs at 100KMH!”  – John Levitt

“I took this product initially to help reduce stress levels but found it also helps me sleep so much better. I feel like a calmer, better version of myself when my adrenal health is balanced. The fact that this product makes me feel amazing, is all natural (no side effects) and contains everything I need in one pill (easy to take) is the reason why I will keep buying this for many moons to come. Top product!” – June Ireland


“After a year of being TATT (tired all the time), I had literally felt what was the point of carrying on. I was sleeping for 12 hours a night and even then I just did not feel refreshed. There were a few emotional upheavals going on in my life at that time but I just didn’t connect the dots between emotional/physical health. My doctor told me that I needed to make some changes to support a healthy thyroid and adrenals otherwise, my body was going to crash. I changed my diet and introduced Adrenasyl to my daily regime and within a few weeks, I was starting to feel a little more energized. I am still not back to normal self but I am heading in the right direction.” – Helen Allport       


“I have always had an issue with my adrenals. My symptoms include lethargy and dizziness but because there is no specific test for poor adrenal health, I had to rule out things like vertigo and thyroid issues, which I did (with my doctor) and I was clear. My doctor told me that I needed to boost my adrenal health and after a lot of research, I understood what I needed to take on a daily basis in order to maintain energy and not feel light headed. I found all the ingredients I needed in one product – Approved Science Adrenasyl! I buy the 6 pack and save hundreds of dollars and the best bit is that they deliver to my house. Great product and great company.”  – Lucy Benjamin

“After being diagnosed with an underactive thyroid, I began researching natural ways in which I could overcome it (I refused to have my thyroid removed surgically). Along the way, I understood the importance of the adrenal glands and how they play a significant role in thyroid health. I have bought many supplements from Approved Science, including Thyrenol, in the past so they of course were my go-to supplier. And they didn’t disappoint with Approved Science Adrenasyl! Together these two products have allowed me to treat my condition naturally and of course enjoy no nasty side effects. I monitor my TSH levels regularly and so far so good! Love the natural way and Approved Science gives me that option.”   – Lauren Feingold

“Adrenasyl made a huge difference to my energy levels. I have a super stressed job and I am an avid runner so needed some help supporting healthy adrenals to maintain my fast paced life. This product does a great job of keeping me on track and I love that it is vegan and all natural. 5 stars!” – Robin Vellenswoth         

“I am in full blown menopause and my energy levels are so low some days, I can barely function. A friend of mine suggested that I support my adrenal glands, which made sense because my hormone levels were all over the place. I wanted something natural as I am taking HRT and didn’t want to confuse my body anymore than it already is! I love that Adrenasyl is vegan friendly too. I would recommend this product to anyone mid age going through menopause.” – May Tollman

FAQs about Adrenasyl:

How does Adrenasyl by Approved Science work?

Each ingredient in this product is supported by clinical research and has a reason to be there!

What’s more, this product includes BioPerine® for enhanced absorption and faster results. This unique formula works to improve adrenal health, support the body in dealing with stress, boost energy and improve sleep. The great thing is that this formula is all-natural which means that it is safe for long-term use.

Do all adrenal support products work in a similar way?

The short answer is basically no, they do not. There are many companies that just ride the trends, producing inferior products with weak formulas in the wrong proportions. Many use incorrect ingredients, fillers, binders or even worse, ingredients that can affect desired results, and even be dangerous.

What should I look for in an effective adrenal support formula?

  • It should contain a Vitamin B complex to support the adrenal cascade.
  • It should contain Mushrooms to help the body cope with stress, restore hormonal balance, and enhance mental clarity.
  • It should contain Vitamin C, Acerola Berry & Rosehip to support the production of cortisol.
  • It should include a variety of adaptogenic herbs to help modulate the body’s stress response as well as increase energy and improve sleep quality.
  • It should contain BioPerine®  proven to increase bioavailability.
  • It should not contain any binders, fillers, additives, hormones, preservatives or artificial ingredients.
  • It must be 100% pure, natural and with no unnecessary ingredients that could reduce the effectiveness of the product.
  • It should be formulated using the same potency as found effective in clinical studies.

Are there any side effects noted when using this product?

Our research did not uncover any negative side effects when using this product. The ingredients that are contained within the formula of Adrenasyl are all-natural and pure. What’s more, they are doctor-approved, so the lack of any negative effects is to be expected. That said, as with any supplement, we always recommend consulting with a doctor if you are pregnant, breastfeeding, have an existing medical condition or are taking any other medication.

What are the dosage instructions for Adrenasyl?

The manufacturers of this product suggest taking 2 capsules per day, before meals with a glass of water. It is advised to take one capsule in the morning and one in the afternoon.

As with any medication or supplement, always follow the recommended dosage instructions and do not exceed them as this poses health risks.

How long before I can see any results?

Results will vary for each person. For some, they will see changes almost immediately, for others it may take longer. It is different for each person. Other factors that affect results can include age, diet, and lifestyle so it is hard to say exactly. What you should look out for are those companies who offer a satisfaction guarantee. This suggests that they are confident that their products will deliver the desired results. And after all, if you don’t get the results you were hoping for you can always return the product. Adrenasyl offers a great money-back guarantee and awesome feedback on how well this product works.

What price should I expect to pay?

The cost of products varies among manufacturers. Unfortunately, many are cheap, useless supplements that have been formulated without any science-based evidence to back them up. Some of these companies are selling their products for over $100 per bottle, which is very expensive. On average, the best supplements we found are selling between the $40-$50 price range. Often, when products appear cheaper, this is indicative of low quality or a low recommended daily serving, which will not bring the results you are looking for. Be aware. Read the labels.

Which adrenal support product should I buy?

As each person’s experience of a product is different, it is difficult to say specifically which one is the best. That said, based on several factors, we did like Adrenasyl. We found, that from 50+ products that we looked at, Adrenasyl had the best quality of ingredients, potency and strength, positive consumer feedback and the manufacturer’s customer service was excellent.

How safe is it to order over the internet?

Adrenasyl is safe to be ordered over the internet.

They also deliver very efficiently and quickly, using discreet packaging.

The Bottom Line

At the end of the day, the bottom line is that consumers have so many options when choosing a health supplement. We are constantly being bombarded with commercials, advertisements and messages about so many different products, for varying health issues that it is beyond confusing which ones are the real deal and which ones are a waste of time.
