📊 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 VISTRA under GMP standards. Astaxanthin is extracted from natural Haematococcus pluvialis microalgae — not synthetically derived.

About VISTRA Astaxanthin Plus Vitamin E 6mg
What is Astaxanthin? Antioxidant mechanism and Vitamin E synergy
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, salmon, and other aquatic creatures.
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 exhibits exceptionally high singlet oxygen quenching capacity and does not convert to a pro-oxidant under high concentrations.
Vitamin E synergy in VISTRA Astaxanthin 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. Per the NIH Vitamin E Fact Sheet (2024), Vitamin E independently protects cell lipid membranes from oxidative damage.
Natural vs synthetic Astaxanthin (see next tab): VISTRA uses Astaxanthin extracted from natural Haematococcus pluvialis, which has a stronger body of research support than synthetic alternatives.
Natural Astaxanthin (algae) vs Synthetic — what is the difference?
The supplement market offers two main sources of Astaxanthin — natural and synthetic — which differ in molecular structure, potency, and research support:
Natural Astaxanthin from Haematococcus pluvialis (e.g., VISTRA): Primarily in ester form (mono- and di-ester), which is stable in nature. The body converts it to free form before absorption. Has the naturally occurring stereospecific structure (3S,3S'). Most published clinical research uses this source, providing stronger evidence for human health benefits.
Synthetic Astaxanthin: Mostly in free form and a mixture of multiple stereoisomers (3S,3S', 3R,3S', 3R,3R') — different from the natural configuration. Limited clinical data in humans. Primarily used in aquaculture and animal feed industries.
Why natural Astaxanthin is preferred for supplements:
Published clinical studies (Davinelli 2018, Ambati 2014) predominantly use natural H. pluvialis-derived astaxanthin.
Stereostructure matches what living organisms naturally produce and use.
May come with complementary carotenoids from the algae that provide additional synergy.
⚠️ Both natural and synthetic Astaxanthin are dietary supplements, not medicines. Consult your doctor or pharmacist for personalized guidance.
VISTRA Astaxanthin benefits — evidence-based uses
VISTRA Astaxanthin Plus Vitamin E 6mg 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 and promote clearer, more radiant skin (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 VISTRA Astaxanthin / Recommended dosage
VISTRA Astaxanthin Plus Vitamin E 6mg 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 VISTRA 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 and leads to more consistent results.
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.
VISTRA Astaxanthin side effects
VISTRA Astaxanthin Plus Vitamin E 6mg 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. At the 6mg/day label dose, this is very rarely observed.
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 sensitivities may be at risk. Consult a doctor before use.
At the label dose of 6mg/day from VISTRA, side effects are generally rare. The GRAS (Generally Recognized As Safe) level in the US is up to 12mg/day.
Contraindications / Precautions for VISTRA Astaxanthin
Before taking VISTRA Astaxanthin Plus Vitamin E 6mg, 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 allergy: Astaxanthin is extracted from Haematococcus pluvialis (a microalgae). Those with known algae allergy 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.
VISTRA Astaxanthin — combinations to know
VISTRA Astaxanthin Plus Vitamin E 6mg 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, enhancing antioxidant synergy
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 and elasticity
⚠️ Use with caution:
Antihypertensives: May have additive blood pressure-lowering effect. Notify your doctor.
Anticoagulants (Warfarin, high-dose Aspirin): 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.
Where to buy VISTRA Astaxanthin?
Where to buy VISTRA Astaxanthin?
Order genuine VISTRA Astaxanthin Plus Vitamin E 6mg at Intimo Life. Delivery across Thailand in 1–3 business days. Shipped in discreet packaging — product name is not shown on the outer box. Browse Astaxanthin at Intimo Life to see all available options.
Take VISTRA Astaxanthin Plus Vitamin E 6mg 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 or taking without fat-containing food prevents stable Astaxanthin levels and delays results.
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 VISTRA 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.
Both VISTRA and Blackmores provide Astaxanthin 6mg from Haematococcus pluvialis plus Vitamin E in their respective Plus formulas. Key differences: VISTRA is a Thai brand widely available across Thailand, accessible in price, and produced under Thai FDA standards. Blackmores is an Australian brand established in 1932, manufactured under Australian GMP standards. Both formulas deliver Astaxanthin at the same dose. Browse Astaxanthin at Intimo Life to compare all available options.
At the standard label dose of 6mg/day from VISTRA, 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.
VISTRA 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. The 6mg/day label dose from VISTRA is within the range reported safe in research. However, if you have existing medical conditions or take prescription medications, consult your doctor about appropriate duration.
Yes — VISTRA Astaxanthin Plus Vitamin E pairs very well with fish oil (Omega-3) supplementation, with added benefits: the fat content in Omega-3 significantly enhances Astaxanthin absorption as a fat-soluble carotenoid. Additionally, both have complementary anti-inflammatory properties — Astaxanthin inhibits the NF-κB pathway while EPA from Omega-3 modulates eicosanoid balance. Taking both together with the same meal is recommended to maximize Astaxanthin bioavailability.
VISTRA Astaxanthin Plus Vitamin E 6mg 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.
