Those are the Health Canada approved uses (NPN 80144587). Oxidative stress occurs when the production of reactive oxygen species (free radicals and singlet oxygen) exceeds the body's antioxidant defenses, leading to oxidative damage to cells, proteins, lipids, and DNA. Astaxanthin neutralizes reactive oxygen species through two primary mechanisms: direct free radical scavenging and exceptionally efficient singlet oxygen quenching.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Is Astaxanthin\u003c\/h3\u003e\n\n\u003cp\u003eAstaxanthin is a xanthophyll carotenoid: a subclass of carotenoids that contain oxygen atoms in their molecular structure (unlike carotenes such as beta-carotene, which are pure hydrocarbons). It is the pigment responsible for the pink-red coloration of salmon, shrimp, lobster, crab, and flamingos. These animals do not produce astaxanthin themselves; they obtain it by consuming astaxanthin-producing organisms in the food chain.\u003c\/p\u003e\n\n\u003cp\u003eIn nature, astaxanthin is produced primarily by the freshwater green microalga Haematococcus pluvialis. Under normal conditions, H. pluvialis is green (chlorophyll dominant). Under environmental stress conditions (high light intensity, UV radiation, nutrient deprivation, high salinity, or temperature extremes), the alga encysts and accumulates massive amounts of astaxanthin (up to 4 to 5% of dry weight) as a photoprotective mechanism. The astaxanthin acts as a biological sunscreen, absorbing and dissipating excess light energy to protect the alga's photosynthetic machinery from oxidative damage. This stress-induced accumulation is why H. pluvialis is the richest natural source of astaxanthin.\u003c\/p\u003e\n\n\u003ch3\u003eNatural vs. Synthetic Astaxanthin: The Stereoisomer Difference\u003c\/h3\u003e\n\n\u003cp\u003eAstaxanthin has two chiral centers (at the 3 and 3' positions of the molecule), giving rise to three possible stereoisomers: (3S,3'S), (3R,3'R), and (3R,3'S) (the meso form). Natural astaxanthin from Haematococcus pluvialis is predominantly the (3S,3'S) stereoisomer. Synthetic astaxanthin (produced petrochemically and used primarily in aquaculture feed to color farmed salmon) is a racemic mixture of all three stereoisomers in approximately equal proportions.\u003c\/p\u003e\n\n\u003cp\u003eThe natural (3S,3'S) stereoisomer from H. pluvialis is considered to have superior antioxidant activity and bioavailability compared to the synthetic racemic mixture. This is the primary reason natural astaxanthin from H. pluvialis commands a premium over synthetic astaxanthin in human supplement applications.\u003c\/p\u003e\n\n\u003ch3\u003eHow Astaxanthin Works as an Antioxidant\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eAmphipathic Membrane Spanning:\u003c\/strong\u003e Astaxanthin's unique molecular structure sets it apart from other antioxidants. Its long conjugated polyene chain (with 13 conjugated double bonds) spans the entire length of the cell membrane lipid bilayer, while its polar hydroxyl and keto end groups anchor at both the inner and outer surfaces of the membrane. This amphipathic orientation allows astaxanthin to provide antioxidant protection at both membrane surfaces simultaneously. By contrast, vitamin E (alpha-tocopherol) is embedded within the hydrophobic core of the membrane and protects only the lipid phase, while vitamin C is water-soluble and protects only the aqueous phase. Astaxanthin bridges both phases.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSinglet Oxygen Quenching:\u003c\/strong\u003e Astaxanthin is one of the most efficient natural singlet oxygen quenchers known. Singlet oxygen (1O2) is a highly reactive, electronically excited form of molecular oxygen generated by UV radiation, photosensitizers, and other processes. It is distinct from free radicals and is not quenched efficiently by most conventional antioxidants. Astaxanthin quenches singlet oxygen primarily by physical energy transfer: the excitation energy from singlet oxygen is transferred to astaxanthin, which then dissipates the energy as heat and returns to its ground state. Critically, astaxanthin is not chemically consumed in this process and can quench multiple singlet oxygen molecules before being degraded. This physical quenching mechanism is significantly more efficient than the chemical quenching mechanisms of most other antioxidants.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFree Radical Scavenging:\u003c\/strong\u003e Astaxanthin also directly scavenges free radicals (reactive oxygen species including superoxide, hydroxyl radicals, and peroxyl radicals) through electron donation and hydrogen atom transfer, similar to other carotenoid antioxidants.\u003c\/p\u003e\n\n\u003ch3\u003eFat Absorption: Why to Take With a Meal\u003c\/h3\u003e\n\n\u003cp\u003eAstaxanthin is a fat-soluble carotenoid. Its absorption from the gastrointestinal tract is significantly enhanced when taken with dietary fat. Dietary fat stimulates bile secretion and the formation of mixed micelles in the small intestine, which are required for the solubilization and absorption of fat-soluble compounds including carotenoids. Without dietary fat, astaxanthin absorption can be substantially reduced. For this reason, the recommended dose specifies taking with a meal containing dietary fat. A meal containing any source of fat (including plant-based fats such as nuts, avocado, or olive oil) is sufficient to enhance absorption.\u003c\/p\u003e\n\n\u003ch3\u003eThe 2-Pack and the 12-Week Duration of Use Guidance\u003c\/h3\u003e\n\n\u003cp\u003eThis 2-pack provides 120 capsules (2 x 60), equivalent to 120 days of supply at 1 capsule per day.

This means the 2-pack supply extends beyond the 12-week guidance period. Consult a healthcare practitioner before beginning the second bottle if you have not already done so. The 2-pack is suited to those who have already consulted a healthcare practitioner and have been advised that continued use is appropriate for their individual needs.\u003c\/p\u003e\n\n\u003ch3\u003eDosage and Supply\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eAstaxanthin (Haematococcus pluvialis, Whole):\u003c\/strong\u003e 15mg per capsule\u003cbr\u003e\n\u003cstrong\u003eSuggested Use:\u003c\/strong\u003e Adults: 1 capsule, 1 time per day, with a meal containing dietary fat\u003cbr\u003e\n\u003cstrong\u003eCapsules per bottle:\u003c\/strong\u003e 60\u003cbr\u003e\n\u003cstrong\u003eBottles in this listing:\u003c\/strong\u003e 2 (120 capsules total)\u003cbr\u003e\n\u003cstrong\u003eSupply per bottle:\u003c\/strong\u003e 60 days at 1 capsule per day\u003cbr\u003e\n\u003cstrong\u003eTotal supply (2-pack):\u003c\/strong\u003e 120 days at 1 capsule per day\u003cbr\u003e\n\u003cstrong\u003eDuration of use:\u003c\/strong\u003e Ask a healthcare practitioner for use beyond 12 weeks (84 days)\u003cbr\u003e\n\u003cstrong\u003eNon Medicinal Ingredients:\u003c\/strong\u003e Hypromellose, Magnesium Stearate, Microcrystalline Cellulose\u003c\/p\u003e\n\n\u003cp\u003eConsult your healthcare provider to determine the appropriate dosage and duration of use for your individual needs.\u003c\/p\u003e\n\n\u003ch3\u003eQuality and Purity\u003c\/h3\u003e\n\n\u003cp\u003e• Health Canada approved (NPN 80144587)\u003cbr\u003e\n• 15mg natural astaxanthin (Haematococcus pluvialis, Whole) per capsule\u003cbr\u003e\n• Natural (3S,3'S) stereoisomer\u003cbr\u003e\n• Vegan hypromellose capsule\u003cbr\u003e\n• Vegan, non GMO, gluten free, dairy free, soy free\u003cbr\u003e\n• 2 x 60 capsules (120 total)\u003cbr\u003e\n• Made in Canada\u003c\/p\u003e\n\n\u003ch3\u003eStorage\u003c\/h3\u003e\n\n\u003cp\u003eStore in a cool, dry place away from direct sunlight.
