Extra Strength Astaxanthin (10 mg) is a dietary supplement that delivers 10 mg of astaxanthin per softgel, sourced from the microalgae Haematococcus pluvialis. Astaxanthin is a naturally occurring carotenoid known for its potent antioxidant properties, helping protect cells from oxidative stress while supporting eye, skin, cardiovascular, and overall wellness. Because astaxanthin is fat-soluble, it is best absorbed when taken with a meal containing fat.
