1 Clinical Trial
4 Documented Benefits
4/5 Evidence Score

AstaReal® is a natural astaxanthin, the red xanthophyll carotenoid produced by the freshwater microalga Haematococcus pluvialis. AstaReal is one of the original and most-studied astaxanthin brands, grown in closed cultivation systems for purity. Astaxanthin is among the most potent lipid-soluble antioxidants known, and AstaReal material has been used in clinical research on skin, eye, and exercise-recovery outcomes.

Studied Dose 4 to 12 mg per day. Skin studies commonly used about 6 mg/day; higher doses are used for exercise and eye support.
Active Compound Natural astaxanthin, a red xanthophyll carotenoid from Haematococcus pluvialis microalgae; a potent lipid-soluble antioxidant that spans the cell membrane.

Benefits

Skin elasticity and moisture

In a controlled human study, daily astaxanthin improved skin elasticity and moisture and reduced the appearance of fine wrinkles, reflecting its antioxidant protection of skin lipids.

Supported by Trial 1

Antioxidant defense

Astaxanthin quenches singlet oxygen and free radicals far more effectively than many common antioxidants, protecting cell membranes throughout the body.

Supported by Trial 1

Eye and visual comfort

Astaxanthin reaches eye tissue and is studied for easing eye fatigue and supporting visual comfort, particularly with heavy screen use.

Supported by Trial 1

Exercise recovery

Its antioxidant and anti-inflammatory actions are studied for reducing exercise-induced oxidative stress and supporting muscle recovery.

Supported by Trial 1

Mechanism of action

1

Membrane-spanning antioxidant

The astaxanthin molecule sits across the full width of the cell membrane, letting it neutralize free radicals at both surfaces, a structural advantage over many antioxidants.

2

Anti-inflammatory signaling

Astaxanthin downregulates inflammatory mediators and supports antioxidant enzyme systems, contributing to its skin, eye, and recovery effects.

Clinical trials

Astaxanthin and Skin Condition — Human Study
PubMed

Controlled human study of oral and topical astaxanthin on skin elasticity, moisture, and wrinkle appearance. (Tominaga et al. 2012, Acta Biochimica Polonica)

Adult women and men.

Astaxanthin supplementation improved skin elasticity and moisture and reduced the appearance of fine wrinkles compared with baseline, consistent with its antioxidant protection of skin.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated — astaxanthin has an excellent safety record at supplemental doses.
A harmless slight reddish or tanned skin tone can appear at higher intakes.
Mild digestive upset is uncommon; take with a fat-containing meal for absorption.

Important Drug interactions

Antihypertensive drugs — astaxanthin may have a mild blood-pressure-lowering effect; monitor.
5-alpha-reductase activity — astaxanthin is studied with saw palmetto; no clinical concern established.
As a fat-soluble carotenoid, take with food and tell your doctor if pregnant or breastfeeding.
