Health Benefits of Astaxanthin


Health Benefits of Astaxanthin

What are antioxidents?
Oxygen interacts with our body’s cells every minute, round the clock. This exposure to oxygen is normal and necessary for the renewal of healthy cells to fight disease.But often the process goes wrong in a process called oxidation. In that case, a damaged cell, called a free radical,is created and attacks other cells. This can cause big problems – speeding up the aging process and harming DNA in a way that can trigger the start of heart disease,cancer, stroke or even Alzheimer’s disease.Overall, free radicals have been implicated in  the pathogenesis of at least 50 diseases.Luckily, antioxidants  substances in a wide range of foods and drinks made from certain plants – can come to the rescue. They neutralize the free radicals, helping prevent some of the damage they might cause. Antioxidants are capable of stabilizing, or deactivating, free radicals before they attack cells. Antioxidants are absolutely critical for maintaining optimal cellular and systemic health and well-being. 

Endogenous Antioxidants
Bilirubin
Thiols, e.g., glutathione, lipoic acid, N-acetyl cysteine
NADPH and NADH
Ubiquinone (coenzyme Q10)
Uric acid
Enzymes:
copper/zinc and manganese-dependent superoxide
dismutase (SOD)
iron-dependent catalase
selenium-dependent glutathione peroxidase
Dietary Antioxidants
Vitamin C
Vitamin E
Beta carotene and other carotenoids and oxycarotenoids,e.g., lycopene and lutein
Polyphenols, e.g., flavonoids, flavones, flavonols, and
proanthocyanidins
Metal Binding Proteins
Albumin (copper)
Ceruloplasmin (copper)
Metallothionein (copper)
Ferritin (iron)
Myoglobin (iron)
Transferrin (iron)

Antioxidants help to neutralize free radicals, which are unstable molecules that are linked to the development of a number of  degenerative diseases and conditions  including cancer,  cardiovascular disease, cognitive impairment,  immune  dysfunction,  cataracts and macular  degeneration.  Fruits and  vegetables are sources of natural antioxidants and among them blueberries have one of the highest levels of antioxidant activity.

Antioxidant activity of dry beans increases with the red color of the beans, red kidney beans being the highest.It was  also observed that red kidney beans had higher activity than other beans.   Similarly, red grapes have higher antioxidant activity than green grapes, and red cabbage is higher than green cabbage.  Antioxidant capacity of blueberries and strawberries containing phenolic anthocyanins are high.Dried fruits like raisins and dates have high antioxidant activities.Antioxidant activities of various fractions of grain during milling process were studied and the results indicate that bran has the highest antioxidant activity and refined flour had the lowest activity.  Antioxidant activities were also studied for ready to eat oat, wheat, corn, and rice cereals.  In whole grain cereals, bran and germ are intact, hence antioxidant activity of whole grain cereals is higher than it is in refined grain cereals.

Astaxanthin
Astaxanthin (asta-ZAN-thin) is a phytochemical from the carotenoid family of xanthophylls and is mainly found naturally in krill, wild salmon, trout, shrimp and crayfish. Carotenoids are what gives color to certain foods and animals like orange to carrots, yellow to sweet potatoes and also gives salmon their reddish color and flamingos their pink feathers.

Scientists know that antioxidants can possibly prevent many of the health problems facing us today. Consumers can get confused because recent studies with vitamin E and vitamin C have been contradicting. Studies are showing that astaxanthin is a powerful antioxidant and anti-inflammatory.

The fallowing is a list of ASTAXANTHIN benefits and scientific studies. It fortifies the immune system. It is the most powerful antioxidant in nature, therefore it neutralizes oxidation, and helps avoid:
1. Cancer
2. Rheumatoid Arthritis
3. Parkinson
4. Alzheimer’s
5. Heart Attack and Embolism

550 times more powerful than vitamin A and 11 times more powerful than Beta Carotene as an antioxidant.

Protects skin from ultraviolet rays damage.

Protects skin from ultraviolet rays damage.

Macular degeneration and the loss of vision related to aging.

Protects us and prevents cancer induced by chemicals.

Increases HDL (healthy cholesterol). 

Astaxanthin protects skin from premature aging.

Gives more energy.

Crosses any cell membrane including the brain barrier.

It has a phytochemical which helps protect from bladder cancer.

Carotenes (Carotenes), absorbed 100% ¡n our body.

Carotenes have an effect anti-tumorial and anti-carcinogenic.

Helps the immune system to produce antibodies to fight against illness.

Helps control bacterial gastric conditions ulcers caused by E. Colli.

Astaxanthin works synergistically with Beta Carotene, luteina and anthaxanthin just as they are found in the cell of haematococcus pluvialis.

Astaxanthin has no side effects.

Astaxanthin improved the health condition, including Rheumatoid Arthritis and Osteoarthritis.

Helps control bacterial gastric conditions ulcers caused by E. Colli.

Astaxanthin works synergistically with Beta Carotene, luteina and anthaxanthin just as they are found in the cell of haematococcus pluvialis.

Astaxanthin has no side effects.

It protects cells from UVA and sun’s UVB radiation damage.

Astaxanthin does not oxidize like other carotenoides in high oxygen concentrations.

It protects the lipid membranes from peroxidation and the damage of mitochondria.

The capacity of the Astaxanthin to neutralize oxygen free radicals is over all the others antioxidant including vitamin C, Beta carotene,vitamin A and all the trans retinal.

Astaxanthin has shown in Vitro,immunomodulator properties in the cells that regularly do not have antioxidant properties.

Astaxanthin has anti-proliferative effects in prostate cancer cells and an inhibiting effect of enzyme activity 5 alpha reductasa associated with the hiperplasion benign of the prostate.

The Astaxanthin has an anti-inflammatory powerful effect.

Astaxanthrin has anti-prolifirative ettects in prostate cancer.

The Astaxanthin has an anti-inflammatory powerful effect.

Astaxanthin increases the production and improvement of semen.

Astaxanthin helps diminish the mammary gland inflammation.

Astaxanthin is effective treating and preventing cold sores wounds originated by the herpes virus simple type 1 due to stress, fever, infection, sunlight,dehydration and other causes.

Astaxanthin helps control inflammation of ligaments, muscles, joints as in arthritis, tenosynovitis, carpal tunnel syndrome.

Astaxanthin retards and prevents skin inflammation and burns from ultraviolet light.

Astaxanthin improves energy and muscular resistance and at the same time it diminishes pain and inflammation due to light or intense exercise.IT IS EXCELLENT FOR ATHLETES.

Astaxanthin retards eye illness and damage to the central nervous system related to aging, diabetes and other degenerative chronic illnesses, sunlight, radiation, ischemic illnesses (bad circulation) and inflammation.

Astaxanthin is a disinfectant and treats gastrointestinal membrane inflammation caused by the Helicobacter Pylon.Helicobacter pylori (H. pylori) are bacteria that many of us have in our stomachs, though many of us do not get sick from it. H. pylori infections can cause peptic ulcers, type B gastritis and gastric cancer.Prevents and treats ulcers.
