Did You Know? Astaxanthin’s unique molecular structure allows it to integrate across cell membranes and provide antioxidant support across both the water-soluble and fat-soluble portions of cells. It is also one of the few carotenoid antioxidants that can reach eye tissues, providing targeted antioxidant support for overall eye health.†

Clinically Supported Ingredients

EyeAstin combines Hawaiian astaxanthin with complementary carotenoids and plant-based antioxidants selected to provide targeted nutritional support for healthy vision and eye function.†

BioAstin Hawaiian Astaxanthin
BioAstin Hawaiian Astaxanthin forms the antioxidant foundation of EyeAstin, providing 6 mg of natural Hawaiian astaxanthin per serving. Its unique molecular structure allows it to integrate across cell membranes and reach eye tissues, helping provide targeted antioxidant support for healthy vision. In this formula, BioAstin works alongside lutein, zeaxanthin, and quercetin to support overall eye health and visual comfort.†

FloraGLO® Lutein
Each serving provides 20 mg of FloraGLO lutein, a clinically researched carotenoid widely used in eye health nutrition. Lutein helps support healthy visual function and provides antioxidant protection from oxidative stress.†

Zeaxanthin
Each serving provides 2 mg of zeaxanthin, a carotenoid that works together with lutein to support macular health and healthy visual function while helping protect the eyes from light-related stress.†

Quercetin
Each serving provides 20 mg of quercetin, a plant-based antioxidant that complements the carotenoids in EyeAstin and provides additional antioxidant support for overall eye health.†

The Science Behind BioAstin Hawaiian Astaxanthin

One of astaxanthin's most remarkable characteristics is its unique molecular structure. Unlike many antioxidants that function primarily in either water-soluble or fat-soluble environments, astaxanthin can integrate across the entire cell membrane, helping support antioxidant protection in both the water-soluble and fat-soluble portions of cells.†

This unique molecular structure also allows astaxanthin to help support healthy cellular function throughout the body. Because it can cross important biological barriers, including the blood-brain barrier and blood-retinal barrier, astaxanthin can provide antioxidant support throughout multiple tissues, including the brain, eyes, muscles, and skin.†

Astaxanthin has several unique characteristics that distinguish it from many other antioxidants:

• Integrates across the entire cell membrane
• Provides antioxidant protection across both the water-soluble and fat-soluble portions of cells
• Can cross important biological barriers such as the blood-brain barrier and blood-retinal barrier
• Helps support mitochondrial protection from oxidative stress
• Provides antioxidant support throughout multiple tissues of the body

Because of these unique properties, astaxanthin helps support healthy cellular function while providing antioxidant support throughout the body.†

Why Hawaiian Astaxanthin Is Unique

Hawaiian Astaxanthin is derived from the microalgae Haematococcus pluvialis, cultivated on the Kona Coast of Hawaii. Nutrex Hawaii produces farm-grown astaxanthin in the United States under carefully controlled conditions designed to ensure purity, potency, and sustainability.

The Kona Coast provides ideal growing conditions for microalgae, including abundant year-round sunlight, a stable tropical climate, and access to pure freshwater drawn from deep Hawaiian aquifers. These natural advantages allow Nutrex Hawaii to cultivate high-quality natural astaxanthin using environmentally responsible farming practices.

The Nutrex Hawaii microalgae farm is considered a BioSecure Zone, meaning it is free from harmful pesticides, herbicides, and genetically modified organisms. Their cultivation process is designed to protect both the environment and product quality while minimizing land impact and water waste.

Fresh water used in the cultivation process is naturally filtered through volcanic lava rock and drawn from pristine Hawaiian aquifers. Much of the water is recycled and returned to the growing ponds to conserve resources and support sustainable production.

These unique environmental conditions and cultivation practices help produce a carefully cultivated source of natural astaxanthin.

Natural vs Synthetic Astaxanthin

Astaxanthin exists in both natural and synthetic forms. Natural astaxanthin is produced by the microalgae Haematococcus pluvialis, while synthetic astaxanthin is typically manufactured through chemical processes and is commonly used in aquaculture to color farmed salmon and other seafood.

Natural astaxanthin contains a complex mixture of stereoisomers and esterified forms that closely resemble the molecular structure of astaxanthin found in microalgae. These naturally occurring forms contribute to the stability and biological activity of natural astaxanthin when consumed as a dietary supplement.

In contrast, synthetic astaxanthin has a different stereoisomer profile and is primarily produced for use in animal feed rather than human dietary supplements. For this reason, natural astaxanthin derived from microalgae is generally preferred for nutritional supplementation.

Astaxanthin used in BioAstin Hawaiian Astaxanthin is sourced from microalgae cultivated on the Kona Coast of Hawaii, providing astaxanthin in a form that closely resembles the astaxanthin found in nature.

Safety & Side Effects of Astaxanthin

Astaxanthin has been widely studied and is generally considered safe when taken at recommended doses. Reported side effects are typically mild and uncommon.

Possible mild effects may include:

• Slight change in skin pigmentation (a light orange tint)
• Orange-red coloration of stool at very high doses

Less common reported effects may include:

• Hair growth changes
• Minor hormonal changes
• Allergic reactions
• Decreased calcium levels
• Low blood pressure

As with any dietary supplement, individuals taking prescription medications should consult a healthcare professional before using this product.

About Nutrex Hawaii

Nutrex Hawaii was founded in Kailua-Kona, Hawaii in 1990 by Dr. Gerald Cysewski, a recognized expert in microalgae and carotenoids. The company was established with a mission to explore the benefits of microalgae and support human health through nutritional supplementation.

Their microalgae farm is located on land carved from an ancient lava flow along the pristine Kona Coast of Hawaii’s Big Island. By combining scientific expertise with Hawaii’s unique natural environment, Nutrex Hawaii has become a leading producer of natural astaxanthin.

BioAstin Hawaiian Astaxanthin has been available in the United States since 1999 and continues to be one of the most widely recognized natural astaxanthin supplements available today.

Environmental Stewardship & Sustainability

Nutrex Hawaii operates with a strong commitment to environmental stewardship and sustainability. Their philosophy is to leave the land and surrounding environment in better condition than when they began operations.

The cultivation process is designed to minimize environmental impact, conserve water, and protect the natural resources of the Kona Coast. Their microalgae farm uses carefully managed freshwater resources, recycles water when possible, and avoids the use of harmful agricultural chemicals.
