Health Benefits of Astaxanthin 4 MG Capsules
Related Topics
Brand name Astaxanthin 4 MG products typically contain multiple ingredients in a complex, though there are some companies that sell this compound as a single-ingredient formulation.
Most Astaxanthin 4 MG supplements contain natural astaxanthin, but some may be manufactured using a synthetic ingredient instead. Other ingredients may include vitamin A (as beta-carotene), vitamin E, lutein, beeswax, lecithin, safflower oil, purified water, carob and/or others.
Astaxanthin is also found in Krill Oil supplements. Krill is a source of omega-3 fatty acids. Some consumers prefer to use this as their source of astaxanthin to derive additional benefits from the health fatty acids that these products provide.
Why Use Astaxanthin Capsules?
The best Astaxanthin 4 MG supplements contain natural astaxanthin which is sourced from Haematococcus pluvialis, a green chlorophyte microalgae.
Astaxanthin is a red-pigmented carotenoid called a xanthophyll. Green-colored H. pluvialis synthesizes astaxanthin when its survival environment becomes unfavorable. This normally is a result of lacking water supply, too much salinity or overexposure to ultraviolet radiation (sunlight).
Natural astaxanthin demonstrates multiple preventive and curative effects in in-vitro and animal trials. The small amount of reliable human research that has been completed also suggests health benefits, but more research is needed to validate results.
Astaxanthin has been associated with anticancer, antidiabetic, cardioprotective (circulatory), renoprotective (kidney), neuroprotective (brain), hepatoprotective (liver), cytoprotective (cell), antiasthma, antibacterial and several other effects.
Astaxanthin capsules are sometimes used for stroke, cancer, age-related macular degeneration (AMD), Parkinson’s disease, Alzheimer’s disease and hyperlipidemia (excessive cholesterol).
Various other possible uses have been tested, but lack reliable evidence currently. Some of the elective uses for natural astaxanthin include treating arthritis, rheumatoid arthritis, male infertility, certain skin conditions, menopause symptoms, carpal tunnel syndrome, indigestion (functional dyspepsia), exercise-induced muscle soreness, hyperlipidemia and sunburn.
How to Use Astaxanthin Capsules Safely
There are no reported adverse effects associated with appropriate use of astaxanthin 4mg capsules. It is a GRAS (generally regarded as safe) food according to the US FDA.
It is likely safe for long-term use in oral amounts commonly gained from human foods. Foods which contain natural astaxanthin include salmon, shrimp, lobster, crayfish, certain crabs, quail and rainbow trout.
When this product is used in supplemental doses, it is rated as possibly safe when doses are kept under or at 40 mg daily. Doses between 4 mg and 40 mg have been used daily for as long as twelve weeks with no adverse effects reported.
When natural astaxanthin is combined with other carotenoids, minerals and/or vitamins, it is rated as possibly safe for up to one year. This data is based on 4 mg daily doses.
Astaxanthin and Beta-carotene
Astaxanthin 4 MG supplements often contain beta-carotene. Beta-carotene is a yellow/orange pigmented carotenoid that gets converted to vitamin A; an essential nutrient.
It is a well-known antioxidant agent. It is used for asthma symptoms, hypertension (high blood pressure), cataracts, certain types of cancer, alcoholism, AIDS, night blindness, diarrhea, infertility, epilepsy, heartburn, sunburn, headaches, psoriasis, vitiligo (loss of skin pigment), depression, Alzheimer’s, Parkinson’s, schizophrenia and AMD.
Astaxanthin and Vitamin E
Vitamin E is a fat-soluble substance which is found in several Astaxanthin 4 MG tablets sold today. Vitamin E is also known for its potent antioxidant properties, but Astaxanthin is considered to be 500x stronger than Vitamin E as an antioxidant.
Vitamin E is used widely to prevent and/or treat hardening of the arteries, heart disease, high blood pressure, some forms of cancer, brain and CNS diseases, disorders of the muscular system, cataracts, asthma, allergies, CFS (chronic fatigue syndrome), cystic fibrosis, scarring, infertility, impotence and peptic ulcers.
Astaxanthin and Lutein
Lutein is a deep-yellow pigment that is sometimes found in astaxanthin supplements. Like natural astaxanthin, it is a xanthophyll.
Xanthophylls are special carotenoids with extra conjugated bonds in their molecular structures. These additional bonds increase antioxidant strength. Lutein has characteristics of a carotenoid crossed with vitamin A.
It is well-known for its positive effects on eye health. It is used widely for AMD, cataracts and other vision disorders. Many also use lutein to prevent and/or treat certain cancer types, cardiovascular disease and type 2 diabetes mellitus.
Conclusions
There are several Astaxanthin 4 MG supplement products available commercially. These dietary supplements contain natural ingredients which are individually known to induce certain healthy benefits. Used singularly, these ingredients are considered safe when taken at appropriate oral dosages .
Negative interactions could occur between Astaxanthin 4 MG capsules and certain types of drugs. Ask your doctor about using Astaxanthin 4 MG supplements to be sure they are safe for you. Be sure to closely follow the manufacturer’s instructions for usage on the product(s) you may choose.
