What is Astaxanthin and what are its side effects?


Have you ever wondered why most marine creatures have white meat and yet a handful have a beautiful pink tone? For many years’ scientists were puzzled by this but once they started looking closer at what made some fish pink, they stumbled upon one of the miracles of nature and one of the most health beneficial elements on earth. Pink sea creatures and fish like salmon, krill, lobsters, and more, contain a substance called astaxanthin. This astaxanthin comes from the algae they eat and has now been shown to have an extraordinary range of health benefits.

The side effects of astaxanthin

For the vast majority of people, astaxanthin is considered safe, however, there are a handful of side-effects as there are with any supplement, natural or otherwise. Of course, many people absorb astaxanthin naturally when they eat red or pink sea creatures, and so on. The amounts absorbed are minimal and thus, unless allergic to the food itself, side effects barely exist. Generally, astaxanthin is taken orally as a supplement in doses of between 4mg and 40mg daily. It can be taken with other vitamins, minerals, and carotenoids with little harm. However, some people will experience more frequent bowel movements with looser stools that have a reddish color, this is quite normal. There are known cases of astaxanthin “overdose”, generally when upwards of 50mg per day are taken, which results in stomach pain. When any of these symptoms occur, generally a reduction in the dosage is required.

As with all supplements, caution is advised when taking astaxanthin for pregnant mothers and breastfeeding mothers. The reason for this is that, at the time of writing, there has been insufficient research into the side-effects of the supplement. Furthermore, it is generally advisable to seek professional medical advice when considering taking astaxanthin, especially when there are underlying disorders where another medication is being taken. 

Overall, astaxanthin is a very safe, natural supplement that has many undeniable health benefits and as research continues it is worthwhile keeping up to date with proceedings.
