AstaReal Astaxanthin (Haematococcus pluvialis)

AstaReal Astaxanthin derived from Haematococcus pluvialis microalgae is a ketocarotenoid-based ingredient with the following profile: Primary bioactive compound is astaxanthin (3,3'-dihydroxy-β,β-carotene-4,4'-dione) at typical commercial concentrations of 4–12 mg per softgel/serving in finished products, with AstaReal oleoresin extract standardized to approximately 5–10% astaxanthin by weight. The compound exists predominantly in esterified form (mono- and di-esters with fatty acids) in H. pluvialis, which enhances stability compared to free-form astaxanthin. Macronutrient content is negligible as it is delivered in small-dose encapsulated form; carrier oils (typically olive or sunflower oil) contribute minor lipid content (~0.5–1 g fat per softgel) which is intentional as astaxanthin is highly lipophilic and fat co-ingestion significantly enhances bioavailability. Micronutrients are minimal and not a primary feature. Additional carotenoids present in the algal matrix include lutein, zeaxanthin, beta-carotene, and canthaxanthin at trace levels (<1% relative to astaxanthin content). Tocopherols may be present as natural antioxidant stabilizers in the extract. Bioavailability notes: Astaxanthin absorption is highly dependent on lipid co-ingestion; bioavailability increases 3–4 fold when taken with a fat-containing meal. Esterified forms from H. pluvialis are hydrolyzed in the gut to free astaxanthin prior to absorption. AstaReal's proprietary cultivation and extraction process yields a predominantly (>95%) natural all-E (trans) isomer configuration, which is considered the most bioactive form. Plasma half-life is approximately 16–52 hours with peak plasma concentrations (Tmax) reached at 6–12 hours post-ingestion. No significant protein, fiber, or carbohydrate content is contributed by this ingredient at standard dosing.
