Astaxanthin - Took 12mg pd for almost 2 months. Cannot say I felt better or stronger for it. Did have sore gums and tongue throughout though, as if on the verge of breaking out with mouth ulcers. Now that I have discontinued astaxanthin for 3 days, soreness is gone. Could be coincidence obviously (I do get funny symptoms in my body quiet regularly)
I took astaxanthin for about 2 weeks and it caused my face to break out with cystic acne. As soon as I stopped taking it, my face cleared up. I would not recommend it.
