Why do we recommend Energysyl?

Low energy can have a negative effect on our quality of life and can lead to brain fog, lack of concentration and focus, and poor memory recall. Constant stress can also impact both our physical and mental health. Many people turn to caffeine as a way to fight fatigue, but this can cause unwanted side effects such as jitteriness or stomach upset. Tolerance also builds up over time, meaning the body will constantly need more and more to get the same results. There are better options in the form of energy boosting supplements which contain natural energy boosting ingredients without caffeine. With so many options available on the market, it can be difficult finding the best supplement to boost energy and fight fatigue.

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. What we really like about Energysyl 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!

Energysyl by Approved Science has produced a formula based on science. It utilizes a full spectrum of B vitamins plus 8 adaptogenic herbs to provide a dual-action solution to boost energy levels as well as combat fatigue. B vitamins are essential for helping our body metabolize the food we eat into energy.  Adaptogens work to counteract the negative effects stress has on the body which can result in serious health issues as well as fatigue. They have been extensively studied and found to have neuroprotective, anti-fatigue, and energy boosting benefits.

The 8 adaptogens found in Energysyl include Siberian Ginseng, Reishi Mushroom, Ashwagandha, Rhodiola Crenulata, Tulsi Extract, Schisandra, Maca, and Cordyceps. These ingredients work synergistically to fight fatigue and regulate the body’s stress response, while ingredients such as Siberian Ginseng, Ashwagandha, and Cordyceps also reduce fatigue and provide antioxidant benefits which protect the body against damage from free radicals. 

The inclusion of BioPerine® ensures the optimal absorption of the active ingredients for faster and stronger results. Additionally, you will not find any ingredients in Energysyl which shouldn’t be there. There are no added fillers, binders, additives, or preservatives and the product does not include caffeine. 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, Energysyl uses top-quality natural ingredients, provides excellent 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 health supplements. This simply comes down to shady companies providing useless formulas that contain unrelated and unhelpful ingredients or that add fillers or binders to their products. Often, these ingredients are not pure, or have not 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, you should beware. Often companies will fill their products with unhelpful and potentially dangerous junk.

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

We were very happy to discover that Energysyl 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.


Energysyl 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

Energysyl is a product created based on scientific research to provide the best possible energy boosting benefits. It contains the optimal blend of ingredients which are clinically proven to be effective at both boosting energy levels and fighting fatigue. These include a patented, full-spectrum B-vitamin complex; a unique, patented adaptogenic complex containing 8 adaptogenic herbs; the most active forms of Folate and Vitamin B12; and BioPerine® to increase the bioavailability of the active ingredients for faster and more effective results.  

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 Energysyl. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution to boosting energy and fighting fatigue, you would be hard pushed to find anything better than Energysyl.

Read on to see what their happy customers are saying

“These pills are a game changer! I feel fantastic and have so much more energy. I made the mistake of not ordering more in time when my first bottle was almost finished and I noticed the difference right away. I was more lethargic, moody, and generally not very happy. When I placed my next order, I made sure to order the 6 month package so that I won’t run out again so quickly. You also get a really great deal when you order this package so that’s a big win. I highly recommend Energysyl!”  – Jenny Moore

“I have been taking Approved Science supplements for years so I was very excited to see they added an energy boosting supplement to their range. Energysyl has helped me tremendously. I caught Covid a few months back and my energy levels just didn’t seem to return to normal. I was feeling tired all the time and it was difficult to get through the day without an afternoon nap. I now feel a million times better. Most days I am able to make it without any nap at all. I also feel more focused and able to concentrate on my daily tasks.” – Bruce Martin

“Energysyl really makes a huge difference in my daily energy levels. I feel like my brain is working better and I am able to focus more at work. When I get home from a long day at the office, I still have energy to keep going and do everything that is needed around the house. I’m even able to make plans with my friends midweek without feeling like I’m going to fall asleep at the dinner table. This product does everything you expect from an energy booster without any unwanted side effects. I am very pleased with my purchase.” – Samantha Adams       

“This is one of the best products I have tried in a long time! I have been trying to find a natural energy booster for a while, but without success. Many I tried made me feel jumpy and I would struggle to fall asleep at night. Then I realized it was the caffeine that was making me feel that way so I needed to find one without. I was very excited to see that Energysyl is completely natural, vegan-friendly and doesn’t contain any caffeine. I also really appreciated the option to buy a larger bottle of capsules that’ll last me a good 3 months. It’s made my routine so much simpler with fewer bottles cluttering up the place, and it also means I make a fantastic saving on the price. I have been taking this product for about a month and I have so much energy! It really does what it says it will.”  – Lucy Cruz

“Energysyl really works for me! I have tried a few other energy boosters on the market but they either left me feeling really sick, jittery or did nothing at all. My friend told me about Energysyl and how good he feels taking it and I have had the same benefits. The product arrived quickly and I will definitely be ordering again!”  – Santiago Gomez

“I have been searching for an energy supplement for a few months. I have bought quite a few different ones so thought I would give Energysyl a try. It is by far the best one I have tried. I stay focused at work and I don’t need as much caffeine anymore. It doesn’t make me feel jittery and there is no crash after a few hours. I’ve also noticed my memory has improved. 5 stars!” – Ryan Bailey         

“During exam period I get so stressed out that I go into overdrive and tire myself out very quickly which leaves me unable to study and too lethargic to exercise even though I know I need to. This time of year always has me in a slump where I end up eating too many snacks in the hopes that they’ll give me energy and help me feel better. I’m thrilled about this supplement that gives me a healthier method of keeping my energy up and is safe for repeated use so I don’t have to limit using it to only the day before and day of an exam. And the fact that this helps my body react to stress has been a real game changer!” – Tiffany Logan

FAQs about Energysyl:

How does Energysyl work?

The key lies in the purity of ingredients contained within this formula – there isn’t a list of ingredients that have been plucked from thin air so that they look good on the label! Each ingredient in this product is supported by clinical research and has a reason to be there! Its unique formula helps boost energy levels as well as fight fatigue for long-term energy boosting benefits. 

Energysyl includes a patented full spectrum B-vitamin complex to boost energy and promote healthy blood cells; a patented adaptogenic herb blend containing 8 adaptogen herbs to fight fatigue and improve the body’s response to stress; and BioPerine® to increase absorption of the other key ingredients for faster results.

Do all energy booster supplements 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 energy booster supplement?

  • It should include a full-spectrum B-vitamin complex to help convert nutrients into energy as well as promote healthy blood cells.
  • It should include the most active forms of Folate and Vitamin B12 (5-Methyltetrahydrofolate and Methylcobalamin).
  • It should contain a variety of adaptogenic herbs.
  • It should not include any caffeine.
  • It should include BioPerine® to enhance absorption for faster and more effective results.
  • 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 Energysyl are all natural and pure. 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 Energysyl?

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

As with any 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. Energysyl 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 vary 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 energy booster supplement 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 Energysyl by Approved Science. We found  that from the 50+ products that we looked at, Energysyl 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?

Energysyl is safe to be ordered over the internet. The manufacturer utilizes the latest encryption software to protect your credit card information and do not engage in shady schemes such as ‘automatic billing’ programs like many other companies do. They also deliver very efficiently and quickly, using discreet packaging.

Why should I choose Energysyl?

There are several reasons why we liked this product including purity of ingredients, customer service, satisfaction, and effectiveness. Its formula is backed by clinical studies and we feel it values consumers’ health above and beyond the profit margins.

This is a great product that you can depend on. It has a well-researched formula with the right ingredients in the correct potency.

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. Energy boosting supplements are no exception, with many companies simply trying to cash in on the latest health trends and pushing their products on unwilling consumers.

We like Energysyl by Approved Science because we feel that this company is different. It is in it for the long haul. It has researched its ingredients well and produced its formula using only pure natural ingredients with a lot of clinical data to back them up. The manufacturer of Energysyl offers what more companies should – an effective, affordable product supported by a real concern for the health of their customers. As an added bonus, Energysyl has many happy testimonials to support our belief that this is a great product and a great company.
