5 out of 5 stars

I am a 65 year old woman with hormone imbalance problems that cause fatigue, lack of energy etc regularly. I bought astaxanthin and will now take 2 x 24 mg a day and see how I go. Thank you for your article. It's knowledgeable and gives one hope. But no good asking a doctor for advice on these things, none of the doctors in the UK have a clue about nutrition/diet/supplements/vitamins etc. We find out far more, quicker and free of charge online.

You're very welcome, Carmel!

Just a reminder, I can not recommend that 48 mg dose because I am not a doctor and there are no studies to support that dose in humans that I am aware of. I used that dose at my own risk. The study in the elderly used just 24 mg/day of Astaxanthin to very good effect, so that dose should be enough, but I did not see that study before I started my test, I saw it at the end of my test, otherwise I probably would have gone with the 24 mg dose.

In the first study they determined that the elderly participants were able to increase the distance they walked in 6 minutes which is similar to what I found myself. In thinking about it, it may have slightly improved my stability when walking because some days, prior to Astaxanthin, I felt a slight instability and after Astaxanthin, that was less noticeable, but that may be down to increased muscle strength?

Please keep us updated on your results after 5 weeks of Astaxanthin!

I forgot to mention in my reply, that I do not have fatigue so I can not comment on that aspect of Astaxanthin, but I did find an article that referenced a study suggesting that it is helpful in relieving daily mental and physical fatigue :

I also found this study suggesting benefit for fatigue : studies have tested the, and physical causes [17]

Here is a relevant study quote :

' Hongo et al., reported that astaxanthin reduced daily fatigue stemming from mental and physical causes [17].'

Although Astaxanthin has recently shown benefit for arthritis due to its antioxidative stress and anti inflammatory activities, I do not believe it is a top tier remedy for arthritis and you are likely to find better remedies for that specific purpose.

I think the most effective remedy reported for arthritis on Earth Clinic is Borax, the laundry additive sold in the laundry detergent aisle in markets across the US.

I am a true believer in Borax because it has kept my arthritis in remission for way over a decade now, as in no arthritic pain. You should read EC's page on Borax, I think you will find it interesting! Here is a link to it :

Further, here is a link to EC's Arthritis page so you can see what remedies work best for arthritis :

Regarding your Plantar Fasciitis, you should also refer to PF remedies on EC which can be found here :

My personal experience is that a combination of remedies is usually the fastest approach for PF.

Good luck!

Do you think this would relieve the pain and discomfort associated with arthritis and joint pain and possibly plantar fasciitis?

I started taking astaxanthin for eye issues which could lead to blindness. Apparently there is astaxanthin in krill oil supplements, but, I am allergic to shell fish.
