ASX safety concerns have been raised, particularly regarding the use of synthetic ASX for human consumption.
The main source of ASX for various human applications, including dietary supplements, cosmetics, and food, is derived from Haematococcus Pluvialis.
This article will exclusively focus on natural Astaxanthin and its attributes within the context of the discussion
Astaxanthin health benefits
Astaxanthin has amazing antioxidant power that has been linked to various health benefits including prevention of cardiovascular disease, immune system enhancement, bioactivity against Helicobacter pylori, and cataract prevention.
ASX has gained attention due to its potential pharmacological effects. These include anticancer, antidiabetic, anti-inflammatory, and antioxidant activities, as well as neuro-, cardiovascular, ocular, and skin-protective effects. Furthermore, it has demonstrated effectiveness in skin cancer chemoprevention.
Humans do not make Astaxanthin.
Astaxanthin products are utilized in various commercial applications, available in a range of dosage forms such as tablets, capsules, syrups, oils, soft gels, creams, biomass, and granulated powders.
Patent applications for Astaxanthin apply to food, feed, cosmetics, and nutraceutical industries, including aquaculture,
- ASX is more bioactive than zeaxanthin, lutein, and β-carotene furthermore exhibits greater antioxidant activity compared to other carotenoids like lutein, lycopene, α-carotene, and β-carotene(1)
- Powerful antioxidant. Immune cells are particularly vulnerable to oxidative stress due to the high concentration of polyunsaturated fatty acids in their plasma membranes. As a result, they tend to generate more oxidative products. An increase of reactive oxygen and nitrogen species can disrupt the delicate balance between oxidants and antioxidants, leading to the degradation of cell membranes, proteins, and DNA. Hence, in conditions of increased oxidative stress, such as during disease states, dietary antioxidants play a pivotal role in maintaining an optimal oxidant-to-antioxidant equilibrium.
- Immune-Enhancing Effects. Activated T cells and NK cells produce interferon-γ (IFN-γ), which is involved in immune regulation and B cell differentiation
- Anticancer benefits. Due to antioxidant compounds, ASX can decrease mutagenesis and carcinogenesis by inhibiting oxidative damage to cells, enhancing immune responses, and potentially exerting antitumor activity
- Anti-inflammatory properties, which can help reduce inflammation in the body and alleviate symptoms associated with various inflammatory conditions such as rheumatoid arthritis, canker sores, carpal tunnel syndrome, and “tennis elbow”.
- Promotes integrated immune response. Repair DNA damage. Various studies demonstrated that dietary astaxanthin has the potential to reduce DNA damage and acute phase protein levels, while simultaneously enhancing immune response.
- Effect on Helicobacter pylori: Multiple studies showed 40 mg/day of AXT significantly decreased symptoms linked with acid reflux, bacterial load, and gastric inflammation. Furthermore improved well well-being of the participants.
- Naproxen-induced gastric and antral ulcer were effectively prevented, and lipid peroxidation in the gastric mucosa was inhibited with high protection.
- Weight loss: lowers oxidative stress in overweight and obese individuals, including smokers.
- Liver Fibrosis. Liver fibrosis is a wound-healing response, triggered by various pathological factors including hepatitis viruses, metabolic disorders, and alcohol consumption. In a Chinese study, 80 mg/kg of astaxanthin showed a notable protective effect against liver fibrosis, suppressing various profibrogenic factors
- Anti-Diabetic Activity. Oxidative stress levels are very high in diabetes mellitus patients. It is induced by hyperglycemia, due to the dysfunction of pancreatic β-cells and tissue damage in patients. Astaxanthin could reduce the oxidative stress caused by hyperglycemia in pancreatic β-cells and also improve glucose and serum insulin levels. Furthermore, it has shown potential in preventing diabetic nephropathy by reducing oxidative stress and renal cell damage, according to these studies.
- Gingival Wound Healing Following High Glucose-Induced Oxidative Stress Diabetic complications are linked to oxidative stress caused by high blood glucose levels, resulting in slow wound healing. Periodontal disease is the result of chronic inflammation of the gum tissues. This study (2022) reported enhanced gingival wound healing due to AXS consumption.
- Astaxanthin benefits eyes. Increased screen time often leads to eye strain, blurred vision, and tension in the muscles of the shoulders and lower back. Extensive research has been conducted on astaxanthin and its positive impact on vision. Multiple clinical trials conducted by the Japanese researchers have demonstrated that ASX enhances visual acuity and reduces eye fatigue. Incorporating astaxanthin into a daily diet can potentially alleviate eye fatigue in individuals who spend prolonged periods working on computer monitors.
- Alleviate the risk of cytokine storm in COVID-19 due to antioxidant properties and anti-inflammatory compounds that lead to the prevention of oxidative damage. ASX is a potent inhibitor of pro-inflammatory cytokines, such as IL-1β, IL-6, IL-8, and TNF-α
- Male Fertility and Reproduction. A double-blind clinical trial, where thirty males were recruited from infertile couples, where female partners did not have infertility problems, showed a significant increase in sperm velocity, the pregnancy rate was 54.5% for the ASX group compared to 10.5 % placebo group.
- Effects on Metabolic Syndrome. AXS can help improve metabolic health by reducing oxidative stress, supporting healthy blood sugar levels, and promoting weight management.
- Improve cognitive functions: A small clinical trial shows multiple brain benefits such as memory improvement and other Higher Brain Functions. Further research is needed.
- Effects on Circulation. As people age, their red blood cells (RBCs) become more vulnerable to oxidative attack, leading to damage in the RBC membrane phospholipids and reduced oxygen-carrying capacity. Multiple studies suggest that AXS can potentially improve microcirculation.
- Polycystic ovary syndrome (PCOS). ASX administration can be beneficial for PCOS patients. PCOS is characterized by a combination of endocrine and metabolic dysfunctions, leading to symptoms like insulin resistance, hyperandrogenism, gonadotropin disorder, and anovulation dysfunction. PCOS is a significant cause of anovulatory infertility in women. Furthermore, patients with PCOS experience endoplasmic reticulum (ER) stress. Iranian small clinical trial where female participants received 12 mg/day for 60 days reported the molecular pathways of ER stress can be modified by ASX as a natural supplement through antioxidant activity. ASX can impact gene and protein expression related to the protein response in GCs. Additionally, ASX might regulate oxidative stress markers in patients’ FF.
- Muscle Performance and Endurance
- Effect on Mitochondrial Function. In a series of experiments using different cultured cell lines, astaxanthin was found to enhance cell survival under oxidative stress caused by antimycin A, which increases mitochondrial ROS generation. The researchers discovered that astaxanthin reduced the production of oxygen radicals within the mitochondria, protecting it from a decline in membrane function that typically occurs over time. Additionally, astaxanthin increased mitochondrial activity by boosting oxygen consumption without generating more ROS.
Astaxanthin skin benefits
Molecular and morphological changes in aged skin not only compromise its protective function but also contribute to the manifestation of skin symptoms.
The process of skin aging involves oxidative events that result in DNA damage, inflammatory response, decreased antioxidant production, and the activity of matrix metalloproteinases (MMPs) that break down collagen and elastin in the dermal layer of the skin.
These include excessive dryness, pruritus, increased susceptibility to wrinkles formation, depigmentation, fragility, impaired wound healing, altered drug permeability, reduced ability to sense and respond to mechanical stimuli, skin irritation, and elevated tumor incidence.
- Reduces the appearance of fine lines and wrinkles by promoting collagen production, which can improve skin elasticity and reduce the appearance of fine lines and wrinkles
- Reduce skin inflammation and improve the appearance of fine lines and wrinkles in aging skin
- Increases skin elasticity and moisture content: making it beneficial for dry and mature skin types.
- Assists with skin renewal: Astaxanthin can assist with skin renewal by minimizing the effects of reactive oxygen species (ROS), which can break down the collagen matrix and increase levels of matrix metalloproteinases (MMP) leading to wrinkle formation and loss of elasticity;
- Reduces hyperpigmentation and age spots
Does astaxanthin reduce wrinkles?
Several clinical studies have reported the effects of ASX in suppressing hyperpigmentation, inhibiting melanin synthesis, and photoaging, and reducing wrinkle formation.
What does astaxanthin do for the skin?
Recent clinical human studies showed a significant improvement in skin condition and appearance when 6 mg /day oral supplementation and 2 ml topical application of astaxanthin derived from microalgae Haematococcus Pluvialis.
Are there any other cosmetic benefits of astaxanthin?
Protects against sun damage: can protect the skin against sun damage and reduce inflammation and dryness.
Food supplement recommendations
It is recommended to take AXS with omega-3-rich seed oils such as chia, flaxseed, fish, walnuts, and almonds
Absorption and bioavailability
Astaxanthin’s bioavailability is substantially affected by meal timing and by smoking. It is facilitated in the presence of fat or other lipids, due to fat-soluble compounds. It is much better absorbed when taken just after a meal than on an empty stomach, high amount of carotenes and it’s 40% less bioavailable in individuals who smoke.
The combination of astaxanthin and fish oil has been found to promote hypolipidemic and hypocholesterolemic effects in plasma. Furthermore, this combination has demonstrated an increase in the phagocytic activity of activated neutrophils, compared to when astaxanthin and fish oil are used individually
Safety of Astaxanthin
Extensive tests conducted by Hoffman La Roche, including assessments for acute toxicity, mutagenicity, teratogenicity, embryotoxicity, and reproductive toxicity, have conclusively affirmed the safety of the product.
Excellent safety and tolerability, with no side effects when it is consumed with food.
What is the Astaxanthin dosage per day?
Astaxanthin 10 mg benefits.
- A single 10 mg dose can persist in the blood for 24 hours and a 100 mg dose for 76 hours
- Astaxanthin supplement 2-4 mg per day is the recommended dose
Is 12 mg of astaxanthin too much?
Clinical studies have demonstrated the safety of orally administered AXS at doses ranging from 4 mg to 100 mg/day, with no adverse or toxic effects observed.
Exceptional health benefits can be achieved with modest dietary intakes of 40 mg/day (2)
Do I need to take vitamin C if I take astaxanthin?
AXS offers superior protection compared to Vitamin C. Its unique molecular structure allows it to be present inside and outside the cell membrane. However, one study reported lowered bronchoalveolar lavage fluid inflammatory cell membrane after feeding AXS with Ginco biloba extract and Vitamin C.
