What qualities to look for in good astaxanthin supplements?
High dose of astaxanthin - It is worth choosing supplements with a high enough astaxanthin content, ideally a minimum of 4-6 mg per dose, to ensure antioxidant efficacy.
Purity and origin of ingredients - Supplements should be derived from natural sources such as the microalgae Haematococcus pluvialis and free from artificial additives and contaminants.
Convenience of dosage - Look out for supplements that require one or a maximum of two capsules per day to facilitate regular use.
Capsulesize - Capsules should be small enough to be easily swallowed, making the supplement more comfortable to take.
Take a look at our ranking of the best astaxanthin supplements:
Astaxanthin by Nutridome is a pure extract of Haematococcus pluvialis algae available in convenient capsules that last for one month of supplementation. Astaxanthin helps to regulate cholesterol levels and has strong antioxidant properties, protecting against free radicals. Testers noticed a significant reduction in inflammation. They also praised that the capsules are easy to swallow and well absorbed. The high quality of the supplement can be seen in the quickly visible effects. The supplement stands out for the purity of its composition, its effectiveness and is completely vegan. Nutridome Astaxanthin is an excellent choice for those seeking natural support for the body, earning well-deserved recognition and first place in our ranking.
Astaxanthin FORTE by OstroVit is a dietary supplement containing an organic chemical compound from the xanthophyll group. Astaxanthin occurs naturally in marine algae and the organisms of fish and seafood. It is worth noting that astaxanthin does not convert into vitamin A in the body, but is a well-fat-soluble compound. Testers emphasise that astaxanthin in this form is best absorbed, especially when taken with fat-rich meals. Among the disadvantages of the product, a rather low daily dose of only 4 mg was mentioned, but doubling the dosage can make it an effective, albeit less efficient, choice that is nevertheless quite cost-effective.
Astaxanthin by Swanson is available in most pharmacies at an attractive price. However, our testers pointed out that the supplement requires long-term use to see results - several packs need to be consumed, which makes the product not very cost-effective. The effects only become visible after a few months, which means that despite the low price, it is not the most cost-effective choice. The dose of astaxanthin is quite low and the results are moderate. Regular use of the supplement protects against free radicals, and some of our testers noticed a reduction in soreness after intense workouts. The supplement does not contain sugar, which was also appreciated, but had to acknowledge the superiority of the rest of the podium.
Now Foods Astaxanthin offers astaxanthin in convenient-to-swallow capsules. Our testers noted that the supplement has a rather pleasant taste, but its effects are rather average and only visible after several months of regular use. With long-term supplementation, astaxanthin boosts immunity and neutralises free radicals, protecting the body from oxidative stress. Testers also noted that the supplement helps to reduce eye fatigue, although the dose is too low to significantly improve vision. You can find better supplements in this price category, offering more pronounced effects. It is not bad, although it is not the product with the best value for money.
Astaxanthin from Solgar is a natural carotene pigment that acts as a powerful antioxidant due to its unique molecular structure. Our testers noticed the effects of use, it is a similar product to the item above. However, Solgar astaxanthin has a few drawbacks - there are only 30 capsules per packet and the astaxanthin dose is quite low. Testers also pointed out the very high price, which makes Solgar Astaxanthin supplementation quite expensive in the long term. Although its antioxidant properties were rated highly by female users, it closes today's list.
