Buying Guide

Check astaxanthin dose per serving

Immune effects in studies commonly use 4–12 mg daily; choose a product whose per‑serving dose matches your target intake or allows easy dosing adjustments

Consider delivery format

Softgels, gummies, and capsules differ in concentration, absorption vehicles, and convenience—pick the format you’ll reliably take and that fits dietary needs

Look for natural, algae‑derived source

Astaxanthin from Haematococcus pluvialis (algae) is the common source in clinical research and is often preferred over synthetic alternatives for supplementation

Verify additional ingredient profile

Check for added oils, sweeteners, or allergens; some formulations include carrier oils to aid absorption or added ingredients targeting eye or skin health

Assess brand transparency and serving count

Choose products that list mg per serving, number of servings per container, and clear labeling of vegan or plant‑based claims to compare value and suitability
