Displaying 1 results of Astaxanthin Stable Isotopes Astaxanthin stable isotopes are a type of isotopic product that are used in research studies to investigate the metabolic pathways of the carotenoid astaxanthin. These stable isotopes are non-radioactive and can be used to trace the movement of astaxanthin in biological systems. Astaxanthin stable isotopes are a valuable tool for scientists studying the effects of astaxanthin on human health, as well as for those investigating the role of astaxanthin in the food industry.
