Approved Science Astaxanthin

If you are looking for a powerful antioxidant that will boost your immune system, support healthy joints, aid eye health and maintain a strong cardiovascular system, then Approved Science Astaxanthin is something that deserves your undivided attention. Of all the Astaxanthin supplements currently available on the market, this is the one that deserves a closer look and very likely, the one that will deliver the immune-boosting benefits you are looking for!

It contains the highest quality, clinically-proven Astaxanthin for promoting a strong immune system, supporting heart and cognitive health, as well as offering muscular support. Each ingredient was handpicked and was the only product we found that provides a potent dose of 12 mg of the patented AstaZine® (the world’s first certified organic Astaxanthin in powder form), sourced from Haematococcus pluvialis, combined with Zinc, a powerful antioxidant and Vitamin E that works synergistically with Astaxanthin for the most effective health benefits. It also contains BioPerine® for increased absorption and super fast results. It does not contain any additives or preservatives and is totally 100% safe to use with no long-term side effects.

Quality: Approved Science Astaxanthin contains high-grade, natural, clinically-verified ingredients that are GMP certified.

Reputation: Their reputation is top quality. This manufacturer has several third-party monitoring services, including buySAFE, Norton, and Trustee, as well as an A+ rating from the quality monitoring company QualityTrusted.

Money-Back Guarantee: Every item sold, is supported by a 60-day 100% money-back guarantee. Such guarantees from manufacturers show strong confidence in their products’ ability to deliver results. Great news for consumers.

What’s more, they are well known in the industry and an established company that provides great customer support service, secure and easy checkout as well as prompt, efficient delivery.

Their commitment to the health industry and consumer is excellent, providing further qualification of efficacy by producing their products in an FDA registered laboratory.

If you are looking for a product that ticks all the boxes for an effective Astaxanthin supplement, from an established reputable company with an excellent money-back guarantee, this is the supplement for you.

It would be good to note that, due to high demand, Approved Science Astaxanthin is often sold out. To avoid having to back order, don’t hesitate to make that purchase when you see it in stock.

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.
