Astaxanthin is one of the most powerful natural antioxidants, with multiple health benefits. In this section, we answer the most common questions about this incredible carotenoid and how it can contribute to your well-being.
What is astaxanthin?
Astaxanthin is a ketocarotenoid, a natural pigment that gives certain organisms a reddish-orange hue. Known as the "king of carotenoids," it stands out for its powerful antioxidant properties, which surpass those of vitamins C and E, and beta-carotene. It is capable of neutralizing free radicals and combating oxidative stress, helping to improve health in various areas, including inflammation, eye health, cardiovascular health, and neuroprotection.
Where is astaxanthin found?
The main natural source of astaxanthin is the microalga Haematococcus pluvialis , which accumulates this pigment as a protective mechanism under stress conditions. It is also present in salmon, trout, krill, shrimp, and lobster, which obtain astaxanthin through their diet. In addition, certain yeast species, such as Phaffia rhodozyma , also produce astaxanthin. Synthetic astaxanthin is commercially available, although its origin and composition vary.
How does astaxanthin work as an antioxidant?
Astaxanthin's unique molecular structure allows it to cross the entire cell membrane, protecting cells from oxidative stress both internally and externally. It effectively neutralizes free radicals, prevents lipid peroxidation, and protects cells from damage. It also boosts the body's natural antioxidant enzymes, strengthening the body's defense system against cellular damage.
What are the potential health benefits of astaxanthin?
Numerous studies support the benefits of astaxanthin in multiple areas of health:
- Anti-inflammatory effects: Helps reduce proinflammatory cytokines and modulates signaling pathways involved in inflammation, showing potential in the management of diseases such as osteoarthritis and colitis.
- Liver Health: Protects against liver fibrosis, non-alcoholic fatty liver disease (NAFLD), and drug-induced liver injury by reducing oxidative stress and inflammation.
- Cardiovascular Health: Improves blood lipid profiles, reduces blood pressure, and improves blood flow, supporting a healthier cardiovascular system.
- Neuroprotection: Thanks to its ability to cross the blood-brain barrier, it protects brain cells from oxidative damage, with potential benefits in neurodegenerative diseases such as Alzheimer's.
- Eye Health: Reaches the retina and protects against age-related macular degeneration and other eye diseases by reducing oxidative stress and inflammation.
- Skin Health: Provides protection against UV damage, improves skin elasticity and hydration.
How is the bioavailability of astaxanthin improved?
Since astaxanthin is poorly soluble in water, its absorption can be improved by consuming it with fats. Furthermore, nanoencapsulation techniques are being developed to further increase its bioavailability, facilitating its use in foods and supplements.
What is the recommended dosage of astaxanthin?
The dosage varies depending on the individual's goal and needs. Studies have shown positive results with daily doses between 4 mg and 40 mg (each Sevens capsule contains 80 mg, so 1 or 2 is sufficient) . It is recommended to consult a healthcare professional for personalized guidance.
Does astaxanthin have side effects?
Astaxanthin is considered safe for consumption. However, in high doses, it can cause mild side effects, such as stomach upset, reddish stools, or slight temporary skin discoloration.
How is astaxanthin commercially produced?
Commercial astaxanthin is produced by culturing Haematococcus pluvialis or by yeast fermentation. Extraction methods include:
- Solvent extraction.
- Extraction with supercritical fluids.
- Mechanical disruption of cells.
There is also synthetic astaxanthin, which has different compositions and bioavailability compared to natural astaxanthin, but it is not approved for use in humans.
