Astaxanthin for Healthy Aging

Research has shown astaxanthin’s health benefits to heart, skin, immune, cognitive and eye health, all of which are common aging aliments.

Aging is generally accompanied by a reduction in cellular energy production, and increased free radical production. This leads to an overloading of defense systems and oxidative damage.1

Studies demonstrate natural astaxanthin is 6,000 times more powerful than vitamin C, 770 times more powerful than coenzyme Q10 (CoQ10), 100 times more powerful than vitamin E, and five times more powerful than β-carotene in trapping energy from singlet oxygen, one of the most common reactive oxygen species (ROS) found in the body.2

A naturally cultivated form of astaxanthin is produced from the microalgae Haematococcus pluvialis. Natural astaxanthin is regarded as superior due to its strength, which is 50 times stronger than synthetically produced astaxanthin.3

Science validated the significant benefits of astaxanthin supplementation for healthy aging. This carotenoid provides support for heart, skin, immune, brain and eye health.

Astaxanthin supports cardiovascular health by improving blood lipid profiles in healthy seniors. It has a protective effect against cholesterol and triglyceride oxidation.4,5,6 Astaxanthin also helps boost mitochondrial energy delivery, which helps the heart muscle contract more powerfully and efficiently.7

Astaxanthin supports normal healthy skin by improving skin elasticity and moisture, and reducing wrinkle formation.8,9 Human studies showed 6 mg/d of astaxanthin for six to eight weeks may reduce wrinkles, water loss and age spots. Astaxanthin also improved elasticity, moisture content and texture of the skin, and the effects seem to be enhanced when combined with the application of astaxanthin topically.8

Studies demonstrated astaxanthin helped balance the immune system and helped suppress overactive immune responses that can create inflammation.10

Astaxanthin helped improve cognitive function in healthy, aged individuals. A human trial that evaluated astaxanthin supplementation with a 12 mg daily dose for 12 weeks, suggested astaxanthin may help protect against age-related cognitive decline.11 Another study demonstrated daily supplementation with 12 mg of astaxanthin improved cognitive health and learning scores in healthy middle-aged and elderly subjects with age-related forgetfulness.12

Astaxanthin helped support eye health, and protected the eyes by reducing oxidative damage and improving blood flow in capillaries.13,14,15 Studies of individuals with age-related macular degeneration have demonstrated significant improvements in retinal health when given astaxanthin and other carotenoids.16
