Heart Health

There is growing evidence that oxidative stress and inflammation are associated with the risk of heart disease (1). Oxidation of low-density lipoproteins (LDL, bad cholesterol) has been linked to increase in the formation of plaques in blood vessels (2). Astaxanthin has been shown to reduce oxidation of LDL (3) and reduce LDL and oxidative stress in a human trial of overweight individuals (4).  Animal studies also showed that astaxanthin may support a delayed progression in high-risk stroke cases (5). It has also been shown clinically that astaxanthin reduces C-reactive protein, which is a biomarker for inflammation and associated with a greater risk of developing heart disease (6).
