Our research has shown that this manufacturer has created a product born from science and clinical data. We found that this was the only Astaxanthin supplement that boasts a daily serving of 12 mg, sourced from the superior source Haematococcus pluvialis, is combined with a potent dose of Zinc and Vitamin E to deliver a powerful boost of antioxidants that provide the ultimate antioxidant protection. This is one of the only Astaxanthin supplements we found that uses the patented form of Astaxanthin – AstaZine®, the world’s first organically certified Astaxanthin, and is served in powder form. Moreover, it includes BioPerine® in its formula for faster absorption and quicker results. We especially liked that this supplement is 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?

Antioxidants have lately become one of the biggest trends in the supplement world mainly because they seem to provide the ultimate all-round protection: boosting immunity, protecting cardiovascular health, heightening cognitive and mental alertness and preserving muscular and joint activity. Astaxanthin boasts not only top antioxidant properties, but it is also one of the most effective natural anti-inflammatories out there. Numerous studies have shown the wonders that Astaxanthin can do not only for the body, but for the mind too. A top Astaxanthin product will protect cells from external stressors as well as enhance the functioning of all cells. Not all Astaxanthin products are created equally and will provide you with the most effective results that you’re looking for. There are several key studies that help pinpoint the way when it comes to finding the most effective Astaxanthin supplement.

First and foremost, Astaxanthin supplements should be made with Astaxanthin that has been derived from the freshwater microalgae Haematococcus pluvialis – the superior and most effective source of Astaxanthin as it is 800 times more powerful than CoQ10. In addition, the amount of Astaxanthin per serving should be at least 12 mg, anything less and it won’t be nearly as effective as shown in clinical studies.

Secondly, it should include Zinc in the formula. Zinc is an essential micronutrient that has strong antioxidant properties. Zinc plays a pivotal role in boosting the immune system, strengthening and supporting bone formation, increasing skin health and sharpening cognitive function.

Thirdly, Vitamin E is a significant addition to an Astaxanthin supplement as it is the ultimate synergistic companion to Astaxanthin. Vitamin E on its own has strong antioxidant and anti-inflammatory properties, but its main role here is to enhance and draw out the antioxidant properties provided by the Astaxanthin.

Lastly, it should contain BioPerine®, for increased bioavailability which speeds up the absorption of the active ingredients for more effective and stronger health benefits.

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 Astaxanthin contains the world’s first certified organic Astaxanthin in powder form – AstaZine® – in a potent dose of 12 mg to provide the ultimate antioxidant protection against free radicals which results in boosted immune function, joint support, cognitive health and anti-aging benefits. 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 Astaxanthin 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 Astaxanthin 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 useless 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 Astaxanthin 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 Astaxanthin 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 Astaxanthin 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 Astaxanthin product, they mistakenly choose a product that is a low dosage or they choose cheap products that contain a less than ideal source of Astaxanthin.

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

  • It is derived from the extra strength source of freshwater microalgae Haematococcus pluvialis.
  • A potent 12 mg daily serving of triple strength Astaxanthin. 
  • The addition of the patented AstaZine® – the world’s first certified organic Astaxanthin in powder form.
  • It contains a lipid-soluble delivery system to ensure the absorption of the Astaxanthin into the bloodstream.
  • The inclusion of Zinc which boosts antioxidant activity, helping neutralize free radicals and prevent further oxidative damage.
  • The addition of Vitamin E which works synergistically with Astaxanthin enhancing the antioxidant properties derived from the Astaxanthin.
  • 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 Astaxanthin. If you are looking for a top-quality formula backed by research and scientific data that is an effective, long-term solution to fight against the environmental stressors that cause free radical damage in order to promote anti-aging benefits, combat inflammation and improve physical and mental health, you would be hard pushed to find anything better than Approved Science Astaxanthin.

Read on to see what their happy customers are saying

“I have to admit, this helped my joint pain tremendously. I’ve been suffering for quite a while from muscle strain in both my arms. The pain was so unbearable I could barely lift anything heavier than a couple of pounds. As soon as I started taking Astaxanthin, I felt almost immediate relief. I couldn’t believe the pain was finally gone.”  – Carmen Stoken

“Not many people may realize this because it’s not what Astaxanthin is known for – but it’s great at improving eyesight. I can feel a huge improvement in my eyes since starting on this supplement, and even my optometrist had to give me a new prescription – for the better. I think this is a great supplement that gives me a serious health boost.” – Kenny Rhodes


“I’ve tried every pill on the market. I have a degenerative joint disease that is hereditary. I saw how slowly but surely it crippled my mom, so I’ve been trying my utmost to extend the life in my joints for as long as possible – I mean modern science must be worth something right? Well no, it seems not quite. I tried all the typical ‘joint supplements’ out there but nothing worked. I felt absolutely no difference whatsoever. This product however, has given me my life back. Finally I found something that not only relieves my pain, but has given me back movement in places I haven’t had for years. This has been life-altering.” – Crystal McCormack      


“Within a week of using Astaxanthin I already noticed a significant improvement. My skin looks brighter, my workouts are more energized and I’m generally in a better mood. This is a winner if you ask me!”  – Terrence Groves


“I have rheumatoid arthritis so a friend recommended that I try out Astaxanthin. Being somewhat skeptical I found a low dose supplement (4 mg) but it did absolutely nothing. I said as much to this friend of mine and she insisted I try a stronger dose. After scrounging around a while online, I came across Approved Science. The formula and dosage seemed to make sense to me. I have to admit that it really has made a difference already – quite unbelievable really.”  – Maddie Taylor

“I am always wary of trying a new brand of supplements so when I’m looking for something new, I naturally turn to the brands I already know and trust – which is Approved Science. I already take some of their other products and know they are a reliable brand that doesn’t fill their capsules with junk. My doctor recommended that I start taking Astaxanthin just as an extra precautionary measure. Immediately I looked up on the Approved Science site whether they have such a supplement and was pleased to see that they do. What I didn’t expect was that within a day I had so much energy left at the end of it – I felt like a kid again..” – Eric Humphrey       

“I’ve been taking Astaxanthin for quite a while already – mainly due to my skin sensitivity to the sun. I’ve had such positive experiences with Astaxanthin giving me that extra bit of protection. More recently I have gone vegan and so I searched for a substitute supplement that is vegan-friendly but will still give me the benefits I have gotten used to. I realized, much to my dismay, that there weren’t many vegan Astaxanthin supplements available since it is mainly oil based so they come in a soft-gel that is made from gelatin. Thankfully I found the Approved Science brand and saw that it is in powder form so it is served in a vegan-friendly capsule. I’m glad to say that this is just as effective if not more than what I was taking beforehand. Thank you Approved Science!” – Stacey Shields

The great thing is that this formula is all natural which means that it is safe for long-term use.

Do all Astaxanthin 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 Astaxanthin supplement?

  • It should provide a powerful daily serving of 12 mg Astaxanthin.
  • It should be derived from the superior source of freshwater microalgae Haematococcus pluvialis for optimal Astaxanthin concentration and health benefits.
  • It should contain Zinc for added antioxidant activity.
  • It should contain Vitamin E which works synergistically with Astaxanthin, enhancing the antioxidant properties derived from Astaxanthin.
  • It should contain BioPerine® proven to increase bioavailability.
  • It should be vegan and lipid-soluble to maximize absorption into the body.
  • 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 Astaxanthin 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 Astaxanthin?

The manufacturers of this product suggest taking 1 capsule per day, preferably with a meal and 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 Astaxanthin 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 Astaxanthin 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 Astaxanthin. We found  that from the 50+ products that we looked at, Approved Science Astaxanthin 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?

The manufacturer utilizes the latest encryption software to protect your credit card information and does 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.

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.
