The side effects of Astaxanthin within supplements or skin care products are yet to be determined; however, it has been used successfully by many around the world.

Bottom Line

9) Our Bottom Line

Astaxanthin is a nutritional supplement advertised as an excellent source of the antioxidant Astaxanthin.

Astaxanthin has become increasingly popular in the supplement niche due to its claimed effectiveness (it is advertised as being 65 times more potent than Vitamin C, 14 times stronger than vitamin E, and 54 times more efficient than beta-carotene).

However, little clinical research or conclusive clinical trial results support these claims.

Overall, Astaxanthin can boost your body’s antioxidant levels and help you feel your best daily. Although some consider it relatively expensive, it is an all-natural organic formula with high-quality Astaxanthin. Nevertheless, results obtained from this supplement may vary by individual.

I tried this because I have heard it is effective in reducing muscle and joint soreness after workouts. I took it before going to gym and I noticed my muscle didn’t hurt as much the next days. I will continue to take it because it is also an excellent source of antioxidants!

I tried this formula after it was recommended to me by a friend. It has had a visible effect on the aspect of my skin from the first month! I actually feel more clear-minded too. I would definitely recommend it!
