Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this product provides the most effective form of Glutathione so that it will be easily absorbed into the bloodstream to provide antioxidant benefits to the body to help improve liver health, maintain optimal cell function, smooth skin tone, and slow down the signs of aging. It is one of the only products to also include Vitamin C to enhance the health benefits of Glutathione as well as BioPerine® to increase bioavailability and the absorption of the other ingredients for faster results. 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? 

Why do we recommend Approved Science Glutathione?

Main Benefits:

  • Provides a unique trademarked Reduced Liposomal Glutathione Complex, Sci-Glute™, delivering the most effective form of Glutathione for optimal health benefits.
  • It contains the optimal dosage of 500mg of Reduced Glutathione which is the active and most effective form of Glutathione.
  • The Glutathione is combined with a patented Phospholipid complex, Pho-Sci™, which is essential for the Glutathione to be absorbed into the bloodstream to be utilized by the body’s cells as it protects the Glutathione from being broken down in the stomach.
  • It contains Vitamin C which boosts antioxidant properties and enhances the benefits of the Glutathione.
  • It contains BioPerine® which is a patented form of Piperine that has been proven to increase bioavailability, for a more effective product.

  • We found so many supportive consumer reviews from users who had experienced excellent results, some within as little as a week.

Glutathione is the most powerful and abundant antioxidant found in the body which protects the body’s cells from oxidative damage to keep you feeling your best and your body functioning optimally. However, as we get older, natural levels in the body decrease which can lead to a number of health ailments as well as speed up the discomforts that come with aging. Research has shown that supplementing with Glutathione can do wonders for slowing the aging process, enhancing the functioning of the cells, improving detoxification and improving liver health to keep the body healthy and in top form. It is important to note that not all Glutathione supplements are created equally. Not all forms of Glutathione will be utilized by the body in the same way to provide the most effective results you are searching for. There are several key studies that help pinpoint the way when it comes to finding the most effective Glutathione supplement to boost health.

First and foremost, Glutathione supplements should contain Reduced Glutathione which is the active form of Glutathione so it is more easy and faster for the cells to utilize it. It is also essential that the Glutathione is combined with Phospholipids in order for it to be absorbed into the bloodstream. Without this liposomal delivery system, the Glutathione will break down in the stomach and it will take much longer for it to be absorbed which means results will not be felt as effectively. Using anything less will compromise the quality of the product you receive.

Secondly, the inclusion of Vitamin C is a significant benefit for experiencing optimal effects. Vitamin C is another powerful antioxidant which helps maintain optimal levels of Glutathione in the body and further enhances its benefits. Not only is Approved Science Glutathione one of the only products we found that contains a significant amount of Vitamin C, 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 even contain any amount of Vitamin C. The addition of BioPerine® increases the bioavailability of the ingredients to enhance absorption for better and faster results.

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.

Approved Science Glutathione contains effective ingredients to increase Glutathione levels in the body to promote its antioxidant benefits, improve liver health, and enhance the function of the body’s cells to boost overall health. 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 Approved Science Glutathione 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, Approved Science Glutathione 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 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, beware, often companies will fill their products with unhelpful and potentially dangerous junk.

That is why, for us, Approved Science Glutathione 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 Approved Science Glutathione 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.


Approved Science Glutathione 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 Glutathione product, they may not realize that there is more to an effective Glutathione supplement than simply containing Glutathione. It needs to contain the correct form of Glutathione at the right dose to be effectively utilized by the body.

Approved Science Glutathione specifically contains the optimal blend of ingredients which are clinically proven to make a Glutathione supplement effective. They are:

  • A unique trademarked Reduced Liposomal Glutathione Complex, Sci-Glute™.
  • The optimal daily dosage of 500mg of Reduced Glutathione, which is the active and most effective form of Glutathione.
  • A patented Phospholipid complex, Pho-Sci™, which provides a delivery system for the Glutathione to bypass the stomach acids in order to be properly absorbed into the bloodstream.
  • Vitamin C to enhance the health and antioxidant benefits of the Glutathione.
  • BioPerine® which increases the absorption of the active ingredients for proven efficacy and faster 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 Approved Science Glutathione. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution to improve health and slow down the effects of aging on the body, you would be hard pushed to find anything better than Approved Science Glutathione.

Read on to see what their happy customers are saying

“I heard Glutathione is the mother of all antioxidants so I bought it hoping it will help me get over colds faster which I get frequently. Since I started taking Approved Science Glutathione about a month ago, I feel amazing. I have a lot more energy, I haven’t been feeling so run down and congested, and what was completely unexpected, is that I also have less knee pain! I am extremely happy with my purchase, I feel years younger! I highly recommend this product.”  – Larry Brighton

“I tried a few different brands of Glutathione but they didn’t really do anything for me and were a complete waste of money. One brand also kept charging me every month and it was a nightmare trying to cancel it. I will never make that mistake again by signing up for automatic billing! It was one of the things which drew me to Approved Science Glutathione – no automatic billing and they provide a 60 day money back guarantee so I knew I at least wouldn’t be throwing money away. So far, I am very happy with the product. I feel energized and no longer hit the snooze button in the morning. This is definitely the brand to buy!” – Susan Clark


“First class product. I learned that glutathione supplements aren’t easily absorbed into the body so I was very pleased that Approved Science Glutathione uses liposomal reduced glutathione which is the best type as it can be absorbed easily. I also like that it includes Bioperine which is known to help with absorption. After using this product for a few weeks, I can already notice an improvement. I feel less tired, more able to focus, less achy, and my skin also looks great.” – Katherine Robinson       


“The original brand of glutathione I was using increased their prices and also started taking much longer for my order to be processed so I decided to take a chance with Approved Science Glutathione. I’m glad I did because I feel great, even better than I was feeling before. The price is great too and I like that I can buy multiple bottles at a time and save money. I give this product 5 stars.”  – Robert Young

“Glutathione has so many health benefits, it is a supplement I think everyone should be taking, especially the over 40 crowd. I did so much research on finding the best product as I know that Glutathione supplements are difficult to absorb, and I came across Approved Science Glutathione which seemed to tick all the right boxes. It’s pure, contains the right ingredients, does not have any additives, and best of all, comes with a 60 day guarantee. And the results have shown I was right to choose this product. I have more energy, I’m sleeping great, and I haven’t had even a sniffle this whole winter. This product is a must-have!”  – Taylor Anderson

“I have lupus and get rashes often and this product has been amazing for me. I read that glutathione is essential for every cell in the body to work properly and those with chronic illnesses are usually deficient so it is important to take a supplement. I highly recommend Approved Science Glutathione.” – Maddison Davis         

“I have only positive things to say about Approved Science Glutathione. I have struggled to lose weight because of insulin resistance, but after a month of taking this product, I am starting to notice that my clothes feel a bit looser and I am wanting to eat more healthy foods rather than just craving sugar all the time. I also have a lot more energy and so I am able to actually follow a workout schedule. I am very impressed and will continue using this product.” – Barry Scott

FAQs about Approved Science Glutathione:

How does Approved Science Glutathione work?

The key lies in the ingredients contained within this formula – they haven’t simply been plucked from thin air so that they have a list of ingredients that looks good on the label! Each ingredient in this product is supported by clinical research and has a reason to be there! Its unique formula is based on clinical studies that have shown huge promise in creating an effective Glutathione supplement. By including key ingredients to optimally increase Glutathione levels in the body, it works to boost health and protect the body. It has included effective ingredients such as a patented Reduced Glutathione complex combined with a Patented Phospholipid complex, plus Vitamin C, in a highly effective dose to ensure optimal effects and fast results.

What’s more, this product includes BioPerine® for enhanced absorption and faster results. This unique formula works to improve cellular function, detoxification, overall health, and antioxidant activity to keep your body functioning at its best. The great thing is that this formula is all natural which means that it is safe for long-term use.

Do all Glutathione 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 Glutathione supplement?

  • It should contain Reduced Glutathione which is the active form.
  • It should provide a daily serving of 500mg Reduced Glutathione.
  • It should contain Phospholipids to ensure the absorption of the Glutathione into the bloodstream.
  • It should contain Vitamin C to further enhance the antioxidant activity of the Glutathione.
  • 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 Approved Science Glutathione are all natural, pure and vegan friendly. 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 Approved Science Glutathione?

The manufacturers of this product suggest taking 2 capsules per day, preferably 30 minutes before mealtime with a 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. Approved Science Glutathione offers a great money-back guarantee and awesome feedback on how well this product works.

What price should I expect to pay?

The costs 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 Glutathione 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 Approved Science Glutathione. We found  that from the 50+ products that we looked at, Approved Science Glutathione 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?

Approved Science Glutathione 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.
