I'd say give it more time. I didn't notice anything until 3-4 weeks and even then it was very minor. It was probably 6+ weeks when I felt a definite improvement. Additionally, I think synergy between rest/diet/exercise is an important helping factor as well. For instance, my aunt, she's been taking astaxanthin for 4+ months now and it's done absolutely nothing for her. However, she never exercises and has a bad diet consisting of lots of animal fat, significant sugar and lots of salt. If like that, I don't think any supplement will be effective.
