#TabletTuesday - Astaxanthin
??This week's #TabletTuesday is definitely more of an educational one. Looking into the benefits, forms and manufacturers of astaxanthin.
???????? ???? ???????????????????????
Astaxanthin is a naturally occurring dark red carotenoid found in nature primarily in aquatic animals such as salmon, trout, krill, shrimp, crayfish, and crustaceans. The microalgae?Haematococcus pluvialis?which grows in fresh water throughout the world is the richest natural source of astaxanthin. Humans, unlike crustaceans, cannot synthesize astaxanthin and have to acquire it through their diet.
Studies have shown natural astaxanthin to be over 500 times stronger than vitamin E and much more potent than other carotenoids such as lutein, lycopene and beta-carotene. Moreover, astaxanthin, a xanthophyll carotenoid, is a nutrient with a unique molecule structure; it does not convert to vitamin A (retinol) and has no “pro-oxidant” activity.
People use astaxanthin for many purposes, including?Alzheimer disease, athletic performance, aging?skin, muscle soreness from?exercise, and many others. Astaxanthin has been shown to actually cross the blood-brain and blood-retinal barriers, meaning it can positively impact disorders related to eye, brain and central nervous system, among others.
Touching on our last episode of Tablet Tuesday, astaxanthin is suitable for vegans and many companies formulate the product.

1.?ROS causes lipid peroxidation of the skin top layer (stratum corneum) which reduces the natural barrier function. #astaxanthin scavenges the ROS in the skin surface which ultimately helps reduce moisture loss and keeps skin smooth.
2. Natural astaxanthin reduces UVB induced inflammation probably via the NF-kB kinase dependant pathway. The less stressed the skin is the better.
3.?Natural Astaxanthin assists skin renewal by minimising effects of ROS. Too much ROS will breaks down the collagen matrix and increase levels of matrix metalloproteinases (MMP) leading to wrinkle formation and loss of elasticity.
?Incorporating the powerful carotenoid astaxanthin into cosmetics will increase the antioxidant status of skin and reduce the effects of ROS at the cellular level. On the surface, skin will look and feel more youthful.
