Astaxanthin is a powerful antioxidant found in microalgae (and the fish that eat the algae) that has potential to reduce oxidative stress, enhance heart health, and support healthy brain aging.

  • Acts as an antoixidant to reduce oxidative stress
  • Enhances heart function by supporting healthy blood flow
  • Promotes more youthful brain function due to its ability to cross the blood brain barrier and and protect brain cells from damage

Research-Supported Benefits:

Supports Cellular Health. Studies suggest astaxanthin supports cellular health by reducing oxidative stress, which contributes to accelerated cellular aging. Astaxanthin’s antioxidant properties protect cells from oxidative damage, improving mitochondrial function. (1)

Protects Against Brain Aging. Research shows astaxanthin exhibits neuroprotective effects, reducing symptoms associated with brain aging. The neuroprotective effects of astaxanthin may be attributed to astaxanthin’s ability to increase BDNF (brain-derived neurotrophic factor), a critical protein that plays a role in memory and learning. (2)

Enhances Heart Health. Animal studies suggest that astaxanthin has cardioprotective properties, reducing cardiac dysfunction associated with elevated blood pressure. (3) Additional research shows that by activating SIRT1, astaxanthin may protect against cardiac damage resulting from a high-fat diet. (4)

Promotes Joint Health. Astaxanthin supports joint health by inhibiting inflammatory-related processes within cartilage cells and reducing degradation of cartilage. (5)

Promotes Eye Health. By improving ocular circulation and protecting against eye-damage associated with computer work, astaxanthin’s powerful antioxidant properties support visual function. (6)

  • Astaxanthin is a carotenoid antioxidant that is primarily obtained through dietary sources such as microalgae and certain seafood like salmon and krill.
  • Astaxanthin functions as an antioxidant to reduce levels of oxidative stress, a key contributor to cellular aging and declining healthspan.
  • Oxidative stress contributes to elevated inflammatory markers, cognitive decline, joint deterioration, vision decline, and increased risk of cardiovascular issues.
  • Studies show that reducing oxidative stress with astaxanthin improves joint, brain, heart, and eye health.

Dana S.
Great for Eye Health!

I can’t really feel anything from taking this but I know it is great for me and eye health. Good dose of 12 mg.

Higher Energy Levels, but Pricey

Been having Astaxanthin 12mg for 2 weeks now, and have observed a distinct increase in my energy levels. It's pricey, though I'd say that it's worth it.

Han X.

It's a great value for a great product.
