Source Naturals Astaxanthin 12mg: Clinical-Strength Pure AstaReal® Microalgae Extract
High-potency, naturally esterified carotenoid delivering 6,000 times the singlet-oxygen quenching capacity of Vitamin C to support dermal elasticity, macular focus, and systemic mitochondrial health.
Source Naturals Astaxanthin 12mg provides a premier clinical dose of natural astaxanthin sourced exclusively from non-GMO Haematococcus pluvialis green microalgae using the gold-standard AstaReal® patented extraction process. Unlike synthetic, petroleum-derived carotenoid alternatives, Source Naturals suspended this fat-soluble antioxidant in pure extra virgin olive oil to maximize intestinal micelle formation and ensure maximum lymphatic uptake across the human digestive tract.
Whether your goal is combating oxidative photoaging, mitigating digital eye fatigue (asthenopia), or sustaining cardiovascular endothelial integrity, this single daily 12mg softgel provides the therapeutic dosage validated across international double-blind, placebo-controlled human clinical trials.
How Astaxanthin 12mg Works: The Transmembrane Bilayer Advantage
Most conventional antioxidants (such as Vitamin C, Vitamin E, or beta-carotene) reside exclusively inside or outside cellular membranes. Astaxanthin possesses a unique chemical structure featuring polar ionic hydrophilic head groups connected by a non-polar conjugated polyene carbon chain. This molecular architecture allows Astaxanthin 12mg to span the entire phospholipid bilayer of human cell membranes:
Transmembrane Span: The hydrophobic carbon chain anchors inside the central fatty core of the membrane to arrest lipid peroxidation, while the polar terminal rings anchor to both the outer and inner aqueous surfaces of the cell.
Zero Pro-Oxidant Activity: Unlike beta-carotene and lycopene, astaxanthin can never transform into a pro-oxidant under high oxygen tension or continuous metabolic stress.
Superior Singlet Oxygen Quenching: Published biochemical comparative assays demonstrate that natural astaxanthin is approximately 6,000 times stronger than Vitamin C, 800 times stronger than CoQ10, 550 times stronger than green tea catechins (EGCG), and 110 times stronger than Vitamin E (alpha-tocopherol) in neutralizing reactive oxygen species (ROS) [Nishida et al., 2007].
Natural vs. Synthetic Astaxanthin: Why Source Naturals Uses AstaReal®

Clinically Investigated Benefits of Astaxanthin 12mg
In a benchmark human clinical trial, oral supplementation with 6mg to 12mg of microalgae astaxanthin for 8 weeks led to statistically significant reductions in crow's-feet wrinkle depth, improved corneocyte hydration in the epidermis, and preservation of dermal collagen fiber networks [Tominaga et al., 2012]. By inhibiting Matrix Metalloproteinases (MMP-1 and MMP-13), astaxanthin prevents UVA-mediated collagen cross-linking and skin laxity from within.
Prolonged exposure to digital screens causes hyper-contraction of the ciliary muscles responsible for visual accommodation. Clinical studies show that 6mg to 12mg of natural astaxanthin crosses the blood-retinal barrier to increase retinal capillary blood flow and accelerate ciliary muscle recovery, significantly reducing visual display terminal (VDT) eye strain, dry eye sensation, and accommodation spasms [Nagaki et al., 2010].
3. Cardiovascular Endothelial Support & Lipid Peroxidation Protection
Circulating low-density lipoproteins (LDL) become atherogenic only when oxidized. Astaxanthin accumulates within circulating lipophilic fractions, protecting LDL particles against oxidative decay. Furthermore, randomized trials demonstrate that daily astaxanthin supplementation elevates serum adiponectin and promotes healthy high-density lipoprotein (HDL) cholesterol levels while supporting arterial nitric oxide production [Yoshida et al., 2010].
Strenuous physical exertion induces radical oxygen species within the inner mitochondrial membrane, impairing ATP production. In double-blind studies on competitive athletes, natural astaxanthin attenuated exercise-induced skeletal muscle damage, lowered plasma lactic acid build-up, and promoted fatty acid oxidation for superior physical stamina [Malmsten & Lignell, 2008].
Pharmacokinetics: Why Source Naturals Suspends Astaxanthin in Olive Oil
Astaxanthin is a lipophilic (fat-soluble) compound with an octanol-water partition coefficient (log P) > 10. When consumed as an isolated powder or in dry tablet forms, intestinal absorption is under 10%. Source Naturals packages 12mg of AstaReal® astaxanthin in a lipid carrier of pure extra virgin olive oil.
The monounsaturated fatty acids (oleic acid) trigger cholecystokinin release, initiating bile acid secretion and forming mixed biliary-phospholipid micelles. This lipid transport vehicle facilitates passive diffusion across enterocyte membranes into lymphatic chylomicrons, resulting in an up to 3.7-fold increase in peak plasma concentrations (Cmax) compared to non-lipid formulations.

Other Ingredients: Extra virgin olive oil, gelatin, glycerin, and purified water.
Allergen Free: Contains NO yeast, dairy, egg, gluten, corn, soy, or wheat. Contains NO sugar, starch, salt, preservatives, or artificial colors, flavors, or fragrances.
Suggested Daily Protocol: Take 1 softgel daily with a meal containing dietary fats (e.g., avocado, eggs, nuts, or coconut oil), or as directed by your qualified healthcare practitioner. Because carotenoid absorption is dependent on fat digestion, taking astaxanthin on an empty stomach drastically lowers systemic absorption.
Important Medical Warnings & Contraindications:
Consult your healthcare provider prior to use if you are pregnant, may become pregnant, or are nursing.
Astaxanthin may inhibit the 5-alpha-reductase enzyme; use caution if currently prescribed 5-alpha-reductase inhibitors or medications for hormonal regulation.
Because astaxanthin promotes balanced vascular tone, individuals taking prescription antihypertensive medications or anticoagulant therapies should monitor blood pressure and clotting factors routinely.
Store in a cool, dry place away from direct sunlight. Do not consume if either tamper-evident neck band or inner bottle seal is damaged or missing.

Frequently Asked Questions About Astaxanthin 12mg
Why choose Source Naturals 12mg Astaxanthin over a 4mg dose?
While a baseline maintenance dose of 4mg per day provides standard cellular support, clinical trials targeting active dermal wrinkle reduction, relief from intensive digital screen eye fatigue, and athletic recovery consistently demonstrate superior therapeutic outcomes at the 12mg daily threshold. Source Naturals provides a concentrated 12mg dose in a single softgel, eliminating the need to take multiple pills.
What makes AstaReal® microalgae extract superior to synthetic astaxanthin?
AstaReal® is naturally harvested from Haematococcus pluvialis microalgae cultivated under sterile, closed photobioreactors. It supplies the 100% natural (3S, 3'S) stereoisomer bound to protective fatty acid esters. In contrast, synthetic astaxanthin is manufactured from petrochemicals, produces unnatural stereoisomers (such as 3R, 3'S and meso forms), is completely unesterified, and lacks human safety validation for high-potency oral consumption.
When is the best time of day to take Astaxanthin 12mg?
Astaxanthin is a fat-soluble carotenoid. To maximize absorption, take your softgel in the morning or midday with a meal containing healthy fats—such as olive oil, whole eggs, Greek yogurt, or nuts. Research confirms that taking astaxanthin alongside dietary lipids increases bioavailability and systemic uptake by up to 300%.
How long does it take to notice skin and eye benefits from Astaxanthin 12mg?
Clinical evaluations demonstrate that eye accommodation improvements and reduced ciliary muscle strain can be observed within 2 to 4 weeks of consistent 12mg daily use. Objective improvements in dermal moisture content, elasticity, and visible wrinkle reduction typically manifest between 6 and 8 weeks of continuous supplementation.
Can astaxanthin cause skin discoloration or turn your skin orange?
Unlike beta-carotene, which can induce carotenodermia (a yellowish/orange tint to the palms and soles) at high dosages, natural astaxanthin at 12mg daily does not cause cutaneous discoloration. Instead, it embeds deeply within the dermal and epidermal strata to enhance photoprotective defense against UV-induced erythema.
Are there any known drug interactions or side effects with Astaxanthin 12mg?
Natural astaxanthin has an established safety record with no reported toxicity in clinical trials. However, because it exhibits mild 5-alpha-reductase inhibiting properties and supports healthy vasodilation, consult your physician if you are taking blood pressure medications, prescription antiplatelet/anticoagulant drugs, or medications for prostate health.
