Astaxanthin 4 provides a pure, concentrated source of astaxanthin – one of Mother Nature’s most powerful and protective antioxidant carotenoids.

It's derived from aquatic algae and is responsible for the rich reddish-pink color observed in many marine species, including salmon, crab, lobster, shrimp, krill and even the flamingo, whose diet is abundant in astaxanthin-producing algae.

It can be found in fish and shellfish that consume astaxanthin-rich organisms; however, its most pure and abundant source is the microalgae Haematococcus pluvialis, which is the natural source used to make this product.

Astaxanthin has been consumed for centuries, but has only recently gained recognition for its extensive health benefits. Recent research shows it to possess antioxidant power many times greater than beta-carotene, lutein, lycopene and zeaxanthin.

Astaxanthin helps protect cell structures from oxidative damage and it can cross the blood-brain barrier to deliver its benefits to the delicate tissues of the brain and nervous system. It is most well-known for the protective benefits it provides to the delicate structures of the eye, enhancing visual accommodation, acuity and eye function.

Astaxanthin’s wide-ranging benefits also extend to the heart, liver, breast and immune system. To assure you the greatest benefits possible, we enhance our pure, natural Astaxanthin with the unique balance of plant-based Omega-3 fatty acids from Ahiflower® oil.

A Powerful Antioxidant at a Moderate Daily Dose

Astaxanthin 4 delivers natural astaxanthin — one of nature's most powerful antioxidants, derived from Haematococcus pluvialis microalgae — at a moderate daily potency, a well-suited starting serving for those seeking everyday antioxidant support in a single softgel capsule.

Supports Eye Health and Vision

Astaxanthin is uniquely able to reach the tissues of the eye, where it helps protect against oxidative stress and supports healthy vision — making it a valued nutrient for those focused on long-term eye wellness.

Supports Brain Wellness

Research suggests astaxanthin can reach brain tissue, where its antioxidant action helps support healthy brain function. That matters, because the brain’s high energy demands make its cells especially exposed to everyday oxidative stress.

Supports Cardiovascular Wellness

As a versatile antioxidant, astaxanthin helps support cardiovascular wellness, including helping protect LDL cholesterol from oxidation, as part of a single daily serving that supports the whole body.
