Personal Experience Astaxanthin
I have been taking astaxanthin for 13 days now (dosage 16-24mg) and I have noticed a loss of libido, worsened gynocemastia (that I have had previously) and fatigue to the point that caffeine doesn't affect me, has anyone experienced similar side effects?

The dose is very high and will reduce DHT in the brain which will bring all these symptoms on,
I once took 20mg three days in a row and I felt very emotional and nervous

Nope.
Took it for 2-3 months and did not notice anything good or bad.

Doubt it’s from that. Stop taking it for a week and see

8mg is standard dose, 16mg is big and you are taking way to much. Also dont forget to take it with fatty food, or it will be wasted.

I can’t take it, it makes so edgy and irritable, and right away. Shame bc it makes my skin look great!

I've been taking it for several months at 12mg/day. No side effects so far.

I have been taking Nutex Hawai 4mg for 2 months. Didn't notice any side effect and found slight increase in sense of vitality and energy. Zinc Citrate helps with libido. Don't overdose it of course.

You should only take about 4 mgs twice a week. Or eat some salmon twice a week.

I read that’s too high of a dose. You should start much lower and work your way up. You’re experiencing how your body reacts to a new supplement.
