A recent study published in Antioxidants highlights the protective benefits of microalgae extract and phytoene, showing they reduce oxidative stress, combat beta-amyloid toxicity, and extend lifespan in a worm model.
About carotenoids Carotenoids are important compounds found in many plant and animal foods. They give bright colors to many fruits and vegetables, and they are also present in egg yolk, dairy, and some seafood. Another rich carotenoid source is the microalgae.
Carotenoids are metabolized to apocarotenoids, and both groups participate in many key plant physiological processes, including photosynthesis, plant communication, seed dispersal agents, and regulatory pathways. Carotenoids reduce the risk of many chronic disorders, including cancer, cardiovascular disease, cognitive impairment, metabolic disorders, and diseases of the skeletal system, skin, and eye. They maintain glowing skin by contributing to skin color and health as well.
This has led to the rollout of carotenoid-containing products of all kinds, including nutraceuticals and supplements, herbal foods, cosmeceuticals, and .
