Astaxanthin
Also known as: 3,3'-Dihydroxy-4,4'-diketo-beta-carotene, Carotenoid, Microalgae Extract
Astaxanthin is a naturally occurring carotenoid with a deep red color, produced primarily by the microalga Haematococcus pluvialis. This exceptional antioxidant is up to 10,000 times more potent than vitamin E at neutralizing free radicals and is one of the most powerful natural antioxidants available. Astaxanthin has been extensively studied for supporting eye health, skin health, cellular protection, and overall wellness through its unique antioxidant and anti-inflammatory mechanisms.
Benefits
Provides exceptional antioxidant protection, with free radical-scavenging power far exceeding vitamins C and E, supporting cellular health at the deepest level. Powerfully supports eye health and vision through its unique ability to accumulate in the retina and support eye structures. Supports healthy skin from within through its collagen-protecting and UV-protective antioxidant properties. May promote cardiovascular health and healthy circulation through its vascular-protective and anti-inflammatory effects. Supports healthy inflammation responses and joint health throughout the body.
Recommended Dosage
Typical dosage ranges from 2 to 12 mg daily, with most studies using 4-12 mg daily for various health benefits. Eye health support typically uses 4-6 mg daily, while higher doses (8-12 mg) are used for intensive antioxidant and anti-inflammatory support. Effects typically develop over 2-4 weeks, with maximum benefits noted at 8-12 weeks. Astaxanthin is best absorbed when taken with meals containing fat.
Food Sources
Astaxanthin is produced naturally by the microalga Haematococcus pluvialis and accumulates in the tissues of animals that consume it, including salmon, shrimp, and other seafood. However, the concentration in seafood is much lower than that found in supplements. Most supplements are derived from cultivated Haematococcus pluvialis microalgae, providing concentrated, consistent doses. While wild salmon contains astaxanthin, the amount is insufficient for therapeutic use.
Side Effects
Generally exceptionally well-tolerated with minimal side effects at recommended doses. Some users experience mild gastrointestinal symptoms including mild nausea or stomach upset. A slight carotenoid pigmentation of the skin (similar to beta-carotene) may occur with very high doses over time. Allergic reactions are extremely rare. Overall safety profile is excellent with very few reported adverse effects.
Interactions
Astaxanthin may interact with anticoagulant and antiplatelet medications (blood thinners) by slightly enhancing their effects; those taking such medications should consult healthcare providers. Generally safe with most medications and supplements. May theoretically enhance effects of other antioxidant supplements, though this is typically beneficial rather than harmful. No significant interactions with common medications have been reported.
Warnings
Not recommended for those with bleeding disorders or those taking anticoagulant medications without medical guidance due to potential mild blood-thinning effects. Pregnancy and breastfeeding safety has not been fully established, though toxicity studies show no harm. Those with shellfish allergies should verify that supplements are sourced from microalgae rather than shrimp or other shellfish. Quality sourcing should be verified to ensure purity and potency.
Deficiency Symptoms
Astaxanthin is not an essential nutrient, so deficiency does not occur. However, inadequate antioxidant intake and limited consumption of astaxanthin-rich foods is associated with reduced antioxidant protection, increased oxidative stress, and accelerated aging, suggesting populations with limited access may benefit from supplementation.

Vitamins
Vitamin D is a fat-soluble vitamin that plays a crucial role in calcium absorption, bone health, immune function, and mood regulation. Unlike most vitamins, your body can produce vitamin D when your skin is exposed to sunlight, earning it the nickname 'the sunshine vitamin.'
Vitamin C
Vitamins
Vitamin C is a water-soluble vitamin and powerful antioxidant that the human body cannot produce on its own. It is essential for the growth, development, and repair of all body tissues and plays a role in many body functions including immune defense, collagen formation, and iron absorption.

Fatty Acids
Omega-3 fatty acids are essential polyunsaturated fats that your body cannot make on its own. The two most important omega-3s found in fish oil are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). They play critical roles in brain function, heart health, and reducing inflammation throughout the body.
