The Science Behind BioAstin® Hawaiian Astaxanthin®

BioAstin® Hawaiian Astaxanthin® provides natural astaxanthin derived from the microalgae Haematococcus pluvialis, cultivated on the Kona Coast of Hawaii. This naturally occurring carotenoid antioxidant supports the body’s natural antioxidant defenses while helping maintain healthy cellular function.†

Astaxanthin’s molecular structure allows it to integrate into cell membranes, helping support protection across both the water-soluble and fat-soluble portions of cells. This unique characteristic helps support cellular integrity throughout the body.†

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

• Integrates across the entire cell membrane
• Supports both 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
• Supports healthy cellular energy production

Because of these properties, astaxanthin is able to provide antioxidant support throughout multiple tissues in the body, including the brain, eyes, muscles, and skin.†

LEARN MORE ABOUT ASTAXANTHIN

Understanding Astaxanthin

Astaxanthin is a naturally occurring carotenoid pigment responsible for the red coloration seen in salmon, shrimp, crab, lobster, and the pink color of flamingos. In nature, this antioxidant originates from the microalgae Haematococcus pluvialis.

This microalgae produces astaxanthin as a protective compound that helps it withstand harsh environmental conditions such as intense sunlight and oxidative stress.

Astaxanthin can be obtained in small amounts from certain foods such as salmon, but the concentration in most foods is relatively low. For example, a person would need to consume large amounts of salmon to obtain the same level of astaxanthin typically provided in a concentrated dietary supplement.

Because the astaxanthin used in these products is derived from microalgae rather than seafood, it contains no fish or shellfish byproducts, making it suitable for vegetarian and vegan formulations.

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.
