Astaxanthin is one of the most potent natural antioxidants, 1 which is:
- 6,000 times stronger than vitamin C
- 800 times stronger than CoQ10
- 550 times stronger than Vitamin E
- 550 times stronger than green tea catechins
- 75 times stronger than alpha lipoic acid
- 40 times stronger than beta-carotene
- 17 times more potent than grape seed extracts
Potent Skin Protection from the Inside Out
Recent studies show that astaxanthin can rejuvenate skin from within, 4 5 6 since it has the ability to scavenge skin-damaging free radicals. 4 7 8 Astaxanthin is widely distributed through most organs in the body, and it also accumulates in the skin, where it makes its way into all skin layers. 9 10 This can provide potent protection against ultraviolet radiation. 4 Skin cells that are exposed to ultraviolet light produce bursts of free radicals that trigger aging effects such as skin sagging and wrinkles. 4 11 When astaxanthin is applied to skin cells in culture, it prevents the ultraviolet-induced destructive effects, suggesting that it significantly prevent ultraviolet-induced skin aging. 4 11 12
Boosting Immune Function
Studies demonstrate that astaxanthin helps balance the immune system by stimulating cellular immunity — while also helping suppress the overactive immune responses. 13 Astaxanthin increases the numbers and activity of white blood cells called lymphocytes and natural killer cells that are responsible for creating the body’s innate immune response to invaders. 14 15 16
Slowing Brain Aging
Unlike many other antioxidant molecules, astaxanthin can cross the blood-brain barrier, allowing it to saturate and protect brain tissue. 17 These features have led experts to label astaxanthin a“natural brain food”. 17 A human study has showed that astaxanthin may improve cognitive health scores and learning scores in healthy middle-aged and elderly subjects with age-related forgetfulness. 18 19
Prevent Massive Body Weight Gain
Astaxanthin supplementation also prevents massive body weight gain in animals fed high-fat or high-fructose diets. 20 21 In overweight and obese humans, astaxanthin suppresses lipid peroxidation and stimulates healthy natural antioxidant defenses in the body. 22 Lab studies reveal that astaxanthin improves metabolism by activating the post-receptor insulin signaling and by reducing oxidative stress, lipid accumulation and proinflammatory cytokines in obese animals. 23-26 In addition, astaxanthin preserved the ability of the pancreas to secrete insulin. 23
Protecting Cardiovascular Health
Astaxanthin can modulate the oxidative condition and may improve vascular histology and endothelial function in rats. 27-29 In humans and animals, astaxanthin helps to normalize lipid profiles while boosting beneficial HDL-cholesterol. 30 31 Astaxanthin also improves the stability of blood vessel structure by decreasing macrophage infiltration and apoptosis. 32 In the heart muscle itself, astaxanthin boosts mitochondrial energy delivery, which helps the heart muscle contract more powerfully and efficiently. 33

Krill Oil vs. Natural Astaxanthin
Many natural sources such as krill and Haematococcus pluvialiscontain astaxanthin, but its concentration in Haematococcus pluvialis is much higher than other sources. The following sources can be found in nature (with the approximate astaxanthin concentrations: 36 37
|Source||Astaxanthin Concentration (ppm)|
|Phaffia yeast||~ 10,000|
|Haematococcus pluvialis||~ 40,000|
Why Choosing Natural Astaxanthin from Algae
Synthetic astaxanthin and natural astaxanthin from Haematococcus pluvialis microalgae are completely different, not only in antioxidant potential, but the molecules are also different in three stereoisomers. One comparison study showed that astaxanthin from Haematococcus pluvialis microalgae is approximatedly 20 to 50 times more active in singlet oxygen quenching and free radical elimination than synthetic astaxanthin. 38 Furthermore, all the human clinical research showing a wide variety of health benefits has been performed exclusively on natural astaxanthin from algae.
CLS Astaxanthin is a complete natural astaxanthin extracted from Haematococcus pluvialis, so it is also suitable for vegetarians.
