📊 Key data from research and health organizations
Astaxanthin has antioxidant potency up to 550× greater than Vitamin E, 6,000× stronger than Vitamin C, and 40× more potent than beta-carotene, according to a review in Marine Drugs (Ambati et al., 2014).
Astaxanthin is the only carotenoid known to cross both the blood-brain barrier and blood-retinal barrier, giving it potential to protect neural and retinal cells.
A study published in Nutrients (Davinelli et al., 2018) found that Astaxanthin may help protect skin from UV-induced damage and reduce visible signs of aging.
Vitamin E (tocopherol) in the formula helps protect Astaxanthin from oxidation before absorption and enhances overall antioxidant capacity, per the NIH Vitamin E Fact Sheet (2024).
🏭 Manufactured by Blackmores, Australia, under international GMP standards. Astaxanthin is extracted from natural Haematococcus pluvialis microalgae — not synthetically derived.

About Blackmores Astaxanthin 6mg Plus
What is Astaxanthin? Antioxidant mechanism vs Vitamin C/E/Beta-Carotene
Astaxanthin is a red-orange xanthophyll carotenoid pigment found naturally in Haematococcus pluvialis — a freshwater microalgae that produces Astaxanthin as a stress response to UV light and nutrient deprivation. It is the pigment responsible for the pink-orange color of shrimp, crab, lobster, and salmon.
Astaxanthin's antioxidant mechanism: Unlike Vitamin C (water-soluble) and Vitamin E (fat-soluble), which each operate only in their respective environments, Astaxanthin is uniquely amphiphilic — its molecule spans the entire phospholipid bilayer of cell membranes, simultaneously protecting both the inner aqueous and outer lipid layers. It also exhibits exceptionally high singlet oxygen quenching capacity and, critically, does not convert to a pro-oxidant under high concentrations (unlike beta-carotene in certain conditions).
Antioxidant comparison:
Astaxanthin: Amphiphilic (both water- and fat-soluble environments). Works inside and outside the cell. Non-pro-oxidant. Potency: 550× Vitamin E, 6,000× Vitamin C, 40× beta-carotene.
Vitamin E: Fat-soluble. Works primarily in the lipid layer of cell membranes. May become pro-oxidant without regeneration.
Vitamin C: Water-soluble. Works in extracellular aqueous environments. Regenerates oxidized Vitamin E.
Beta-carotene: Pro-vitamin A carotenoid. May act as a pro-oxidant at high concentrations under oxidative stress conditions.
Vitamin E synergy in Blackmores Astaxanthin 6mg Plus: The Vitamin E in this formula protects Astaxanthin from oxidation during storage and before absorption, while Astaxanthin helps regenerate oxidized Vitamin E — forming a mutually reinforcing antioxidant network.
Blackmores Astaxanthin 6mg Plus provides Astaxanthin that may help support several body functions, based on current research reviews:
Skin health and UV protection: Astaxanthin may help protect skin from UV-induced photo-oxidative damage by scavenging reactive oxygen species (ROS) in the epidermis and dermis, and may help reduce visible signs of UV-related aging (Davinelli et al., Nutrients 2018).
Eye health: Astaxanthin crosses the blood-retinal barrier and may help protect the retina from oxidative stress and UV-induced damage. Some studies suggest it may help reduce digital eye fatigue.
Anti-inflammatory support: Astaxanthin has anti-inflammatory properties via NF-κB pathway inhibition and reduction of pro-inflammatory cytokines (TNF-α, IL-6), per a PubMed review (2021).
Cardiovascular support: Some research suggests Astaxanthin may help support LDL oxidation levels and triglyceride balance.
Exercise performance: Astaxanthin may help reduce exercise-induced oxidative stress and muscle damage.
⚠️ Astaxanthin is a dietary supplement, not a medicine. Benefits listed reflect nutritional support for normal body functions. Consult your doctor or pharmacist for personalized guidance.
How to take Blackmores Astaxanthin 6mg Plus / Recommended dosage
Blackmores Astaxanthin 6mg Plus is taken as follows per label instructions:
Label dosage: 1 capsule once daily (providing 6mg Astaxanthin per day).
Research context: Most clinical studies on Astaxanthin use 4–12 mg/day. The 6mg dose in Blackmores falls within the range used in skin and eye health research.
Timing — IMPORTANT:Always take with a fat-containing meal (e.g., breakfast or dinner with olive oil, eggs, or any dish containing dietary fat). Astaxanthin is a fat-soluble carotenoid — dietary fat significantly enhances its absorption.
Do not crush or chew: Swallow the capsule whole with water.
Consistency over timing: Taking at the same time each day maintains stable Astaxanthin blood levels better than irregular use.
If you miss a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and continue normally. Do not double dose to compensate.
Blackmores Astaxanthin side effects
Blackmores Astaxanthin 6mg Plus is generally well tolerated at the recommended dose. Based on WebMD and research reports, potential side effects include:
Skin discoloration (at higher doses): Slight orange-pink tint to the skin (carotenodermia) due to Astaxanthin accumulation in skin layers. This is harmless and reversible upon dose reduction or discontinuation.
Gastrointestinal: At higher doses, some individuals may experience mild bloating, stomach discomfort, or loose stools — reducible by taking with food.
Blood pressure: Astaxanthin may have a mild blood pressure-lowering effect. Those on antihypertensive medications should inform their doctor.
Allergic reactions: Those with algae or seafood sensitivities may be at risk. Consult a doctor before use.
At the label dose of 6mg/day from Blackmores, side effects are generally rare. The GRAS (Generally Recognized As Safe) level in the US is up to 12mg/day.
Contraindications / Precautions for Blackmores Astaxanthin
Before taking Blackmores Astaxanthin 6mg Plus, be aware of the following important precautions:
⚠️ Pregnant or breastfeeding women: Insufficient safety data exists for Astaxanthin supplementation during pregnancy and breastfeeding. Always consult your doctor before use.
⚠️ Algae or seafood allergy: Astaxanthin is extracted from Haematococcus pluvialis (a microalgae). Those with known algae allergy or seafood sensitivity should consult a doctor before use.
⚠️ Antihypertensive medications: Astaxanthin may have an additive blood pressure-lowering effect. Inform your doctor and monitor blood pressure regularly.
Anticoagulants: At higher doses, Astaxanthin may have mild platelet effects. Those on Warfarin or other anticoagulants should notify their doctor.
Hypoglycemic drugs: Some reports suggest Astaxanthin may affect blood glucose levels. Diabetic patients should monitor closely.
Children under 18 years: Consult a doctor or pharmacist before use.
Astaxanthin vs other antioxidants — how to choose?
There are many antioxidants on the market — here is a practical comparison to help you choose:
Astaxanthin (e.g., Blackmores 6mg): The most potent amphiphilic carotenoid. Works in both water and fat environments. Crosses blood-brain/retinal barriers. Best for: UV skin protection, eye health, anti-inflammatory support, exercise recovery. Ideal for those with high UV exposure, prolonged screen use, or intense exercise.
Vitamin C: Water-soluble. Regenerates Vitamin E. Essential for collagen synthesis. Good for general skin health and immune support.
Vitamin E: Fat-soluble. Protects membrane lipids from oxidation. Works best when Vitamin C is present to regenerate it.
CoQ10: Mitochondria-level antioxidant. Good for energy production and cardiovascular health.
Simple guide: Choose Astaxanthin when you want antioxidant protection against UV skin damage, digital eye fatigue, and oxidative inflammation — browse Astaxanthin at Intimo Life to compare all options.
Blackmores Astaxanthin — combinations to know
Blackmores Astaxanthin 6mg Plus can generally be combined with many supplements, with some interactions to note:
Generally safe to combine:
Vitamin C — helps regenerate oxidized Astaxanthin and Vitamin E
Omega-3 (fish oil) — dietary fat in Omega-3 improves Astaxanthin absorption and provides anti-inflammatory synergy
Lutein/Zeaxanthin — same carotenoid family, complementary eye health roles (Astaxanthin: oxidative protection; Lutein: blue light absorption)
Collagen peptides — complementary for skin health
⚠️ Use with caution:
Antihypertensives: May have additive blood pressure-lowering effect. Notify your doctor.
Anticoagulants: Notify your doctor before combining.
Multiple carotenoid note: Taking multiple carotenoids at high doses simultaneously (e.g., Astaxanthin + high-dose Beta-carotene) may result in absorption competition. Consult a pharmacist.
Always inform your doctor or pharmacist of all supplements and medications you are currently taking.

Take Blackmores Astaxanthin 6mg Plus with a fat-containing meal — breakfast or dinner both work. Astaxanthin is a fat-soluble carotenoid; having dietary fat present (even salad dressing, eggs, or meat) significantly enhances absorption. Taking on an empty stomach substantially reduces bioavailability. There is no strong evidence that morning is better than evening — daily consistency matters most.
Astaxanthin is a fat-soluble carotenoid that accumulates in tissues over time. Noticeable effects typically begin after 4–8 weeks of consistent daily use. In skin research (Davinelli et al., 2018), improvements in skin moisture and smoothness were observed after 8 weeks. Eye health and anti-inflammatory benefits may take 4–12 weeks depending on the individual. Inconsistent intake prevents stable Astaxanthin levels and delays results.
Both Astaxanthin and Lutein are carotenoids beneficial for eye health, but they work differently. Lutein accumulates in the macular region of the retina and acts as a blue light filter to protect photoreceptor cells — best for macular health and screen-related blue light exposure. Astaxanthin crosses the blood-retinal barrier and neutralizes singlet oxygen and ROS from UV light and oxidative stress across the retina, with some research suggesting it may help reduce eye fatigue. The two are complementary — some individuals use both for broader coverage. Consult a pharmacist if unsure which is right for you.
Current research data on Astaxanthin use during pregnancy is limited. WebMD and health professionals recommend that pregnant and breastfeeding women should consult their doctor before taking Astaxanthin, as there is insufficient evidence to confirm safety at supplemental doses. If antioxidant support is desired during pregnancy, a doctor can recommend alternatives with a more established safety profile.
At the standard label dose of 6mg/day from Blackmores, the chance of noticeable skin discoloration is very low. Carotenodermia (orange skin tint) occurs at much higher doses (e.g., 20–40mg/day or more over extended periods) and is rarely observed at typical supplement dosages. If it does occur, it is harmless and fades when the dose is reduced or stopped. Unlike jaundice (from liver disease), carotenodermia does not cause yellowing of the whites of the eyes.
Blackmores Astaxanthin 6mg Plus stands out through: (1) Blackmores is Australia's leading natural health brand established in 1932, manufacturing under international GMP standards. (2) The 'Plus' formula adds Vitamin E for antioxidant synergy, protecting Astaxanthin from oxidation before absorption. (3) Astaxanthin is derived from natural Haematococcus pluvialis microalgae, not synthetic sources. (4) The 6mg/day dose aligns with research used in skin and eye health studies. Available genuine at Intimo Life.
Blackmores Astaxanthin can be taken daily on an ongoing basis — cycling off is generally not required. As a fat-soluble carotenoid that accumulates in tissues, consistent daily use maintains stable Astaxanthin levels more effectively than intermittent use. WebMD reports that Astaxanthin at 4–40mg/day has demonstrated safety in short-to-medium-term studies. At the label dose of 6mg/day from Blackmores, this is within the well-studied safe range. However, if you have existing medical conditions or take prescription medications, consult your doctor about appropriate duration.
Blackmores Astaxanthin 6mg Plus is best suited for: Frequent sun exposure (outdoor activities, sports) — wants antioxidant UV skin protection | Heavy screen users — seeking eye health support and reduced digital eye fatigue | Active exercisers — wanting to reduce post-exercise oxidative stress | Antioxidant seekers wanting coverage in both water and fat environments. Not recommended without medical advice: pregnant women, those with algae allergy, children under 18. This is a dietary supplement, not a medicine — it does not directly treat any disease.
