Our research has shown that Approved Science has created a product born from science and clinical data and does exactly what is meant to do – boost your immunity! We found that this was the only product to contain the exact ingredients needed to optimize your body’s defense mechanisms to boost a strong immune system. Their clean, effective formula provides 960 mg of Elderberry, Echinacea, Garlic, Vitamin C and Zinc for helping your body fight viruses and infections. The dosage is based on clinical studies which suggests that these guys are serious about what they do. We liked that it’s served in an easy to swallow 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 Approved Science Immune Booster?

Main Benefits:

  • It contains a high dose of Black Elderberry (Sambucus nigra) (360 mg), which has been shown to positively impact the strength of immunity. 
  • It contains a high amount of Echinacea and Garlic, both essential ingredients for supporting a healthy immune system. 
  • It contains the optimal RDA of Vitamin C which is a key vitamin to support the body.
  • It also contains Zinc in the correct ratio.
  • It does not contain any preservatives, artificial colorings, hormones, or unnecessary ingredients that may dilute the efficacy of the product.
  • 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.   


When our immunity is compromised, for whatever reason, we lay ourselves open to microbes that can enter our body and put our health in jeopardy. Albeit the immune system is an incredible miracle in itself, it is not infallible. The mistake many people make is thinking that it will work well without any additional support, but this is not the case. We can help it be stronger. Alongside dietary and lifestyle changes, there are many ingredients that have been linked to help boost our immune systems to ensure that our body’s defense mechanisms are fully optimized. There are several key studies that help pinpoint the way when it comes to finding the most effective oral supplement to address immune boosting.

First and foremost, Immune Boosting supplements must be made using pure and natural ingredients so that they are safe for long-term use in order to establish, maintain and boost a strong immune system without any negative side effects. Using anything less will compromise the quality of the product you receive.

Secondly, the inclusion of Elderberry is a significant benefit as the berries (and flowers) of this beneficial plant are packed with antioxidants and vitamins that can boost your immune system. They have been shown to reduce inflammation in the body, reduce stress, and provide cardiovascular benefits also. Positively linked with easing cold and flu symptoms, this go to ingredient is renowned for its high potency of antioxidants that help encourage our natural immune process. 

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 Immune Booster contains effective ingredients, backed by research and clinical data, that positively encourage boosting immunity. 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 Immune Booster 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 Immune Booster 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 unhelpful 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, Approved Science Immune Booster 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 Immune Booster 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 Immune Booster 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 Immune Boosting product, they don’t always understand what they are looking for in terms of effective ingredients, potency and dosage. It is essential that an effective formula contains key ingredients to help support the body in building a strong immune system. 

Approved Science Immune Booster specifically contains the optimal blend of ingredients which are clinically proven to help build immunity and strengthen the body’s defense mechanism. These include:

  • Black Elderberry (Sambucus nigra)
  • Echinacea
  • Garlic
  • Vitamin C
  • Zinc

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 Immune Booster. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution for optimizing and strengthening your immune system, you would be hard pushed to find anything better than Approved Science Immune Booster.

“My immune system has always been weak, ever since as a child I had glandular fever. So every winter I am susceptible for any of the cold and flu germs going around. I have tried many different products and tactics to avoid being sick, but none really did the trick until I started taking Approved Science Immune Booster. It is such a simple, yet hugely effective formula that has been the difference for me not being sick. Since I have started taking it (6 months ago) I have not had a cold (or flu) and generally have felt much better in myself. This is a great product because it contains only the ingredients I need to keep me healthy. I give it 5 stars. ”  – Jeff Turner

“I was diagnosed with asthma when I was 21 and I take a preventative steroid as well as Ventolin as and when I need it. Generally, on the whole, it does not affect my quality of life. However, around allergy season I am more prone to wheezing, coughing and asthma attacks as my body’s immune system tries to cope with the onslaught of microbes coming its way. My doctor suggested it may help to boost my immune system so I went hunting for the best product – and I found it! Approved Science Immune Booster! This has helped me tremendously and I have found a huge difference during allergy season. I like that it is safe to use long term and everything is natural so I don’t see any horrible side effects. I checked with my doctor that the ingredients are safe to take and she agreed that they. I am very happy I found this product and I would recommend it.” – Lorraine Duffy


“Approved Science Immune Booster has helped me boost my immune system like nothing I have ever taken before, which is why I want to share my positive review! I am a firm believer in preventative medicine and do everything I can to avoid getting sick. However, after a particularly nasty divorce, I was left depleted of energy and exhausted all the time. This went on for months. I didn’t know what to do until my sister told me that I should look to boost my immune system – I didn’t connect the two but boy was she right. I upped my daily vitamin C levels and started to take Approved Science Immune Booster. The difference has been incredible. As a side note, as a long time IBS sufferer, I have to say that my gut health also seems to have benefited from this product also. I am so happy I listened to my sister (for one in my life!) and I am enjoying a new lease on life. ” – Janey White       


“Age brings wisdom, which is great, but it also brings ailments, not so great! As I aged, I found my existing autoimmune thyroid disorder stacked on a whole pile of health issues. My TSH levels were out of control and forget the T3 & T4 – off the scale. I won’t go into all the details but in short it significantly affected my daily life. I started researching and understood that I could help my body by building my immune system to help overcome many of the challenges I was facing. I made some significant life changes in terms of diet and exercise and I began eating very healthy. I introduced several natural health supplements to the mix including omega-3 and a natural immune booster. I chose to purchase these products from Approved Science as I found the very best reviews around, they offer a great money back guarantee if you are not happy with the results and also that they base their formulas on clinical data and scientific research. I am beyond happy with the results. I get that my thyroid issues will never ‘go away’ as such and I will always have to manage them weekly, but I feel so much better and so much healthier. Thanks Approved Science for giving me my life back. ”  – David Fox 

“I love Approved Science and all their products they offer! They are the good guys in the nutritional health supplement industry and I for one swear by them. I have bought many different products from them so when I found out they offer an Immune Boosting product, I didn’t hesitate to purchase it. Top quality and reasonably priced. I have been taking it for 7 months and have not even had a sniff of a cold! I have recommended this to several friends and they also love it!”   – Carol Gregg

“Thank you Approved Science Immune Booster is all I can say!! After a particularly horrible life experience that left me battling for my health, I needed something to pep me up and boost my immunity. You gave me what I needed. I love that it is all natural and I can take it without any side effects against the other medication I am on. I feel more energized and generally much more healthier.  ” – Roger Wordsworth         

“My stress levels were through the roof, my skin looked a mess and my stomach was painful and bloated daily. I thought that there was something seriously wrong with me. After numerous tests my doctor told me that I was overworked, run down and my immune system wasn’t functioning optimally. Firstly, I was so relieved. Secondly, I began my search for a good quality immune booster – enter stage right Approved Science Immune Booster! It contains exactly the key ingredients that I was looking for and love that it is all natural. I bought the 6 month package and saved a lot of money and have to say, since I started taking it, I have not looked back. I feel great!” – Sam Brydon

Do all Immune Boosting 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 Immune Boosting formula?

  • It should contain clinically-proven Black Elderberry (Sambucus nigra).
  • It should contain a strong potent dose of Vitamin C.
  • It should contain ingredients which are clinically proven to support the immune system such as Garlic, Echinacea and Zinc.
  • 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 Immune Booster 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 Immune Booster?

The manufacturer of this product suggest taking 2 capsules per day, preferably 30 minutes before mealtimes with a glass of water. 

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 Immune Booster 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 Immune Boosting 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 Immune Booster . We found that from the 50+ products that we looked at, Approved Science Immune Booster had the best quality of ingredients, potency and strength, positive consumer feedback and the manufacturer’s customer service was excellent.
