Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this is one of the few vegan-friendly probiotic formulas available on the market. The formula contains a unique patented blend of 10 of the most beneficial strains of probiotics, including Saccharomyces boulardii, plus the prebiotic, Fructooligosaccharides (FOS), to support the growth of healthy bacteria. It provides a culture count of 25 billion CFU which is the optimal amount for best results. We really liked that this product comes with discounts for bulk purchases and a 60-day money back guarantee if you are not happy with the results. 

Why do we recommend Approved Science Probiotic?

Main Benefits:

  • It contains a unique patented blend of 10 strains of probiotics called Pro-Sci™ from the genus LactobacillusBifidobacterium, and Saccharomyces boulardii which are the most researched effective probiotic strains. Each probiotic type offers a different benefit, so the more that are present, the better. 
  • It contains the prebiotic Fructooligosaccharides (FOS) which helps the probiotics travel through the digestive tract to the gut, promoting the growth of healthy bacteria. It also maintains a healthy gut pH balance.
  • It provides a probiotic culture count of 25 billion CFU, which is the ideal strength for optimal effectiveness.
  • It is a vegan-friendly formula which is unique in the world of probiotics. Most probiotics are based on dairy.
  • It does not contain any preservatives, artificial colorings, hormones, or unnecessary ingredients that may dilute the efficacy of the product.
  • We found 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.


The gut is made up of trillions of microbiota, both good and bad, which play a role in our overall health. When there is an imbalance of healthy and bad bacteria in the gut, this is when health issues arise. An imbalance could be the result of diet, age, genetics or medications. Taking a probiotic supplement helps restore the balance of the bacteria in the gut, which will improve both your gut and overall health. As there are many types of bacteria and yeasts found naturally in the gut, taking a supplement with multiple strains of probiotics is your best bet for optimal results as each type provides a different benefit. The inclusion of a prebiotic is also beneficial as this will help the gut absorb and utilize the probiotics as well as maintain a healthy gut pH level.

Approved Science Probiotic contains Pro-Sci™, 10 strains of the most researched and effective probiotic strains from the Lactobacillus and Bifidobacterium families. It also contains Saccharomyces boulardii which is a unique yeast strain that provides a range of health benefits. It provides a potency of 25 billion CFU (Colony Forming Units) which is an effective concentration. This is a measure of the product’s culture count indicating the number of healthy bacteria it contains.

What’s more, Approved Science Probiotic also includes the prebiotic Fructooligosaccharides (FOS) which is essential for a probiotic supplement to work effectively. A probiotic supplement can only work well if the gut can absorb it. FOS helps the probiotics travel through the digestive tract to the gut where it can be used. FOS also helps maintain the pH balance of the gut.

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.

This product contains effective probiotics and a prebiotic to address gut health which is great but what we really like is that it is made by a company which 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 Probiotic 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 who manufactures such a unique, well-researched product. It is vegan-friendly too!

To summarize, Approved Science Probiotic uses a unique blend of 10 strains of probiotics, PLUS Fructooligosaccharides (FOS) for enhanced benefits, comes at a great price with excellent deals, and is backed by a 60-day money-back guarantee. 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 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 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 Probiotic is a product that does not fall within this category. Its formula contains only 10 strains of probiotics plus a prebiotic delivered in a veggie capsule. It does not contain any unnecessary or harmful ingredients. 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 Probiotic 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 Probiotic comes at an affordable price with some excellent multiple purchase deals, allowing for huge cost savings for consumers. Also, this company will not put its customers on any auto-ship program, which can be nearly impossible to cancel should you wish.

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 probiotic supplement, they don’t always address all the important factors which need to be considered. Other than the probiotics and other ingredients a product contains, 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 Probiotic. If you are looking for a top-quality probiotic supplement backed by research and scientific data that is an effective, long-term health solution, you would be hard pushed to find anything better than Approved Science Probiotic.

“So many of the probiotic supplements that I have tried in the past only contained one or two probiotic types, and they didn’t really do much for me. Then I came across Approved Science Probiotic which contains 10 strains and I thought it sounded amazing so I better give it a try. The first thing I made sure of was if they have a money back guarantee, which they do, so I knew I wouldn’t be risking much if I bought it and didn’t like it. But I LOVE it!! These probiotics have seriously helped my stomach issues. I have no more pain and no more cramping. It is such a relief to not be in constant pain.”
– Madison Parker

– Teresa Foster


FAQs about Approved Science Probiotic:

How does Approved Science Probiotic work?

The key lies in the ingredients contained within this formula – they haven’t simply been plucked from thin air so that there is a list of ingredients that looks good on the label! Each strain of probiotic in this product is supported by clinical research and has a reason to be there! The inclusion of the prebiotic Fructooligosaccharides (FOS) enhances the benefits of the probiotics in the body, as well as helps the gut to produce more healthy bacteria. The formula also contains the optimal culture count of the probiotics at 25 billion CFU.

This unique formula works to improve gut health which is essential for your overall health. The great thing is that this formula is all natural, and vegan-friendly, which means that it is safe for long-term use.

Do all probiotic 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 probiotic supplement?

  • It should contain multiple strains of probiotics as each strand provides a different benefit.
  • It should contain a patented blend of probiotics where possible.
  • It should contain Saccharomyces boulardii which is a probiotic heavily supported by research for its anti-inflammatory and immunomodulatory health benefits. 
  • It should contain a prebiotic to enhance the benefits of the probiotics. FOS is the most popularly favored prebiotic.
  • It should provide a potency of at least 20 billion CFU. This is the culture count of the probiotics, so the higher the better, but too high can also have negative effects.  
  • 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 Probiotic 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 medications.

What are the dosage instructions for Approved Science Probiotic?

It is recommended to take two capsules a day. For the best results, take one capsule in the morning and one capsule in the afternoon, 30 minutes before a meal.

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. Approved Science Probiotic 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 probiotic 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 Approved Science Probiotic. We found that from the 50+ products that we looked at, Approved Science Probiotic 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 Probiotic 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 Approved Science Probiotic?

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. And if that wasn’t enough, check out the customer reviews – they say it all. It counts with many happy customers clearly singing the praises of this trustworthy product who are highly loyal to this brand. We will summarize the key benefits one more time:

The Bottom Line

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

It has researched its ingredients well and produced its formula using only pure natural elements with a lot of clinical data to back them up. The manufacturer of Approved Science Probiotic offers what more companies should – an effective, affordable product supported by a real concern for the health of their customers.
