What is the recommended dosage for Astaxanthin?

What is astaxanthin and how may it support cardiovascular health?

Astaxanthin is a carotenoid pigment found in salmon, shrimp, and microalgae with potent antioxidant properties. Clinical studies suggest it may improve lipid profiles, reduce oxidative stress markers, and improve blood flow. Its antioxidant capacity is reported to be significantly greater than vitamin E.

What dosage of astaxanthin has been studied for cardiovascular outcomes?

Clinical trials have used 4–12 mg of astaxanthin per day. Lipid profile improvements have been observed at 6–12 mg daily for 8–12 weeks. The most studied form is derived from Haematococcus pluvialis microalgae. Astaxanthin is fat-soluble and should be taken with meals for optimal absorption.

What are the potential side effects of astaxanthin?

Astaxanthin is generally well tolerated at studied doses. Mild side effects include changes in skin pigmentation (slight reddish hue at high doses), digestive discomfort, and altered bowel habits. It may lower blood pressure and blood sugar, so caution is advised when combined with related medications. Long-term safety data is limited.

About

Astaxanthin is a xanthophyll carotenoid with antioxidant potency 6,000x greater than vitamin C, uniquely spanning the entire cell membrane bilayer. A 2020 meta-analysis of 14 RCTs found it significantly reduced plasma MDA (lipid peroxidation marker) and increased total antioxidant capacity. Studies in overweight subjects showed significant LDL and oxidative stress marker reductions.

How It Works

A xanthophyll carotenoid with antioxidant potency 6,000x greater than vitamin C; spans the entire cell membrane bilayer providing protection against lipid peroxidation; reduces ox-LDL formation; improves blood rheology by increasing membrane fluidity of erythrocytes; modulates inflammatory pathways via NF-kB and JAK/STAT inhibition.
