If you’re looking for one of the strongest natural antioxidants out there, then look no further! Astaxanthin has been tagged as the ‘king of antioxidants,’ and for good reason. This impressive supplement has been clinically linked to help boost the immune system, support cardiovascular health, slow down cognitive decline, facilitate healthy joints and more. It’s hard to believe but Astaxanthin is 800 times stronger and more potent than CoQ10 for providing antioxidants which offer a plethora of benefits to improve your health.

Astaxanthin is a keto-carotenoid that is responsible for the pink color in salmon and shrimp. Carotenoids not only have strong antioxidant properties, but are also lipid-soluble which means the body absorbs it quickly and effectively. The best source of Astaxanthin that has the highest concentration of antioxidants, is sourced from freshwater microalgae Haematococcus pluvialis. This powerful ingredient is what gets you the positive results you are looking for and can be found in a top-quality Astaxanthin nutritional supplement.

However, it can be beyond confusing for consumers, not knowing which Astaxanthin products are worth buying and which are worthless fakes. We carefully examined which products are backed up with scientific support and real explanations as to why they have formulated their version of an Astaxanthin supplement in the way that they have.

What Is The Science Behind Astaxanthin?

Astaxanthin belongs to one of the many well-known micronutrients called carotenoids which are reddish in color. Carotenoids are pigmented phytochemicals found abundant in plants, bacteria, algae, and a variety of other living organisms. They are one of the most diverse groups of natural pigments, which are responsible for the bright orange, red and yellow colors primarily in veggies, fruits, and many plant parts. 

Carotenoids are natural potent antioxidants that are extremely effective at protecting cells against oxidative stress and environmental damage which helps slow down the aging process as well as boost health and wellbeing. Astaxanthin is one of the most powerful natural antioxidants available partly due to its unique molecular structure which is also lipid-soluble meaning it is absorbed easily by the body. It works by preserving the integrity of cell membranes by inserting itself in their bilayers to help protect the functional integrity of mitochondria.

Astaxanthin is an antioxidant powerhouse 6,000 times stronger than Vitamin C and 550 times more potent than Green Tea catechins offering a myriad of health benefits including improved cardiovascular, cognitive function, blood health, boost immunity, reduce inflammation, promote healthy joints as well as boost physical performance & recovery. The body cannot produce Astaxanthin on its own so supplementation is essential.  

Our Research On Astaxanthin Supplements

When looking for an effective Astaxanthin supplement to achieve optimal positive health benefits, you must read product labels to better understand exactly what you are putting into your body. We were able to immediately spot manufacturers that were simply out to make a quick return and cash in on the latest trends versus the products that we consider to be high quality and effective supplements that will bring positive results.

Our research identified key clinically-proven ingredients which should be included in an Astaxanthin supplement in order to enjoy optimal health benefits. These include:

  • At least 12 mg of Astaxanthin
  • Astaxanthin sourced from microalgae Haematococcus pluvialis.
  • Zinc – provides strong antioxidant properties.
  • Vitamin E – works synergistically with Astaxanthin enhancing its benefits.
  • BioPerine® (black pepper extract) – increases bioavailability for speedier results in order to receive the positive benefits of the above ingredients faster and more effectively.

Thorough research takes time and money, which most people don’t have an endless supply of. So, we did the work for you, saving you both. We researched numerous Astaxanthin supplements to ascertain an in-depth analysis of what is out there on the market.

To determine those products that we could rate as beneficial, we looked to see if they contained the correct concentration and ingredients, how potent they were and their grade of purity. We eliminated products that we found to contain synthetic fillers, unnecessary ingredients and those that each pill showed inconsistency with each other.

However, that was not all, we didn’t stop there. We understand that facts and figures don’t always tell the whole story. So, we looked for real consumers who had purchased and used the products and asked them for their feedback. Their testimonials helped us to establish a list of the best possible products currently available based on the experience of real consumers.

How To Find A High-Quality Astaxanthin Supplement

OK, so….there are several key elements to look out for that can pretty much guarantee the product’s authenticity. 

  • Optimal Dosage and Purity: We eliminated any products with synthetic fillers, unnecessary ingredients and inconsistent pills.
  • Verified Customer Reviews: We reviewed testimonials of real consumers who had purchased, used the products and given feedback.
  • Monitoring by a Third Party: Using third-party organizations to independently monitor and track the reputation of a manufacturer and assess their customer satisfaction levels is crucial.
  • 100% Money Back Guarantee: A strong guarantee demonstrates the confidence that manufacturers have in their products.
  • External Testing: Third-party testing substantiates and verifies the quality of the manufacturer’s product. It can be very expensive for manufacturers to undertake and even disqualify entire shipments of products that don’t reach the correct standards.

We are very confident in the brands that we did pick. Given our stringent parameters and reasons for choosing our recommendations, we are sure our suggestions will help you achieve the results you are looking for.

NOW Extra Strength Astaxanthin

Promoted as a new and improved Astaxanthin product, we were curious to see what the NOW brand added as their new features to optimize the antioxidant and immune-boosting properties that Astaxanthin offers.

Advertised as having over twice the amount of Astaxanthin as their regular strength product, this particular Astaxanthin boasts a 10 mg serving. While this is impressive, we would have liked to see the clinically researched amount of 12 mg. We appreciate that the Astaxanthin used is from the superior source Haematococcus pluvialis, and is manufactured in a GMP certified facility, however we felt that it was still lacking some key ingredients that are backed up by clinical research.

Some ingredients we felt were missing included Zinc – an important antioxidant component, as well as BioPerine®, which increases the bioavailability to help active ingredients absorb quicker and more efficiently. While we were happy to see the addition of Vitamin E since it plays such a vital role in enhancing the antioxidant properties found in Astaxanthin, it is listed as one of the inactive ingredients in this product. We would have liked to see it take a more prominent position with an exact amount listed. Ultimately what won us over was the sheer amount of positive reviews despite the fact that there is no satisfaction guarantee.

Nutricost Astaxanthin

We liked this product due to the many positive reviews we found online. We also appreciate that this product is manufactured in a GMP certified facility and is third-party tested. However, along with the positive reviews, there were a number of negative ones claiming that this product doesn’t work. 

The one and only ingredient in this formula is Astaxanthin. While it is served at the ideal amount of 12 mg per serving and is derived from the superior source Haematococcus pluvialis, we were disappointed that there isn’t much more to this product. We do appreciate the generous dose of Astaxanthin, but we feel that it could be that much more effective if the manufacturer had added ingredients such as Zinc, Vitamin E and BioPerine®. We were sorely disappointed that the manufacturer made no effort to add anything more to the Astaxanthin to boost its antioxidant effects.

We liked that this product comes with a money-back guarantee, although it is only relevant for products purchased directly from the manufacturer’s website and doesn’t include third-party sites such as Amazon. Continue reading to see what else this product has to offer.
