Vitamin A Benefits
Vitamin A comes in two forms: retinol and beta carotene. Retinol is the animal source of vitamin A, while beta carotene is derived from a variety of yellow and orange fruits and vegetables as well as leafy greens. Beta carotene is converted into vitamin A in the intestine and as well in the liver.
Vitamin A Benefits
Vitamin A has many essential functions that include good eyesight, growth and tissue healing and a healthy skin. It as well plays an essential role as an antioxidant, lowers cancer risk and regulates genetic processes.
Vitamin A Deficiency
Studies have shown that around 25 percent of Americans get less than half the advisable daily allowance in their supplements for vitamin A. This is most obvious in people who do not eat many fruits and vegetables or those who eat highly processed foods which are lacking in vitamins. Fruits and vegetables actually are very essential foods for anyone wanting to get the required intake of nutrients.
Night blindness is one of the first symptoms of vitamin A deficiency along with poor vision, irritated or red eyes and eyes that tire easily. Vitamin A or beta carotene supplements will normally correct these predicaments. Less obvious deficiency symptoms can include atrophy of the thymus and spleen which are both essential for a healthy immune system. Low foodary levels of vitamin A have as well been linked to a number of cancers including breast, cervical, lung, prostrate and stomach.
Vitamin A Toxicity
As vitamin A is stored in the body and not readily excreted, there are some potential toxicity issues. Taking more than 25,000 IU a day of vitamin A retinol is not advisable. Animal liver meat has the highest concentration with beef liver containing around 15,000 IU. Toxicity is highly unlikely through food alone as most of the vitamin A we eat comes from vegetable sources. There are no toxicity concerns with beta carotene. The only side effect may be an orange or yellow discolouring of the skin.
Beta Carotene foods and Vitamin A Sources
The highest concentrations of vitamin A retinol are found in liver and fish liver oil, which is a general source for supplements. Egg yolks and milk generate including whole milk, cream and butter are as well good sources. Provitamin A in the form of beta carotene is found mainly in yellow and orange-coloured fruits and vegetables such as carrots, papaya and leafy green vegetables.
Drinking too much alcohol, vitamin E deficiency, extreme iron intake and cortisone drug can reduce absorption of this fat soluble vitamin.
Why Vitamin A is important for health

Vitamin A is the name of a group of compounds that include retinol, retinoic acid, and retinal. As with most vitamins, it cannot be made in the body and can only be obtained through food and supplements.
There are two main forms of vitamin A, depending on food source. Vitamin A from animal sources is absorbed as retinol, which can be converted into retinal and retinoic acid in the body. Retinol can be toxic in large doses.
Plants do not provide vitamin A. Instead they contain pro-vitamin A carotenoids that can be made into vitamin A by our bodies. Unlike retinol, carotenoids are not toxic in large amounts. They are potent antioxidants and aid in cancer prevention. Of all the carotenoids, beta-carotene is the most common, and most easily converted to retinol.
Vitamin A is probably best known for its role in preventing night blindness and other vision problems. What is less known is that it is also important for bone growth, reproduction, and cell division.
It helps the immune system to fight infections by making the white blood cells that destroy viruses and bacteria. It also promotes healthy skin and mucous linings that act as a barrier against the viruses and bacteria.

What is Astaxanthin
Astaxanthin is a carotenoid. The astaxanthin molecule is similar to beta-carotene, but all evidence indicates that it is a far more powerful biological antioxidant.
Astaxanthin, unlike some carotenoids, does not convert to Vitamin A (retinol) in the human body.
Like many carotenoids, it is a colorful, fat/oil-soluble pigment. Too much Vitamin A is toxic for a human, but astaxanthin is not.
However, it is a powerful antioxidant. It is 10 times more capable than other carotenoids.
Astaxanthin contains in microalgae, yeast, salmon, trout, krill, shrimp, crayfish, crustaceans, and the feathers of some birds.
Here some benefits of astaxanthin:
- Astaxanthin increases strength and endurance. 2 – 8 times greater increase over baseline verses placebo in human clinical study.
- Astaxanthin combined with Flavangenol is powerful against diabetes complications
- Astaxanthin protects cells and mitochondrial membranes from oxidative damage, thus protecting the cell from oxidative damage and have incredible cancer fighting properties
- Astaxanthin will boost the immune system by increasing the number of antibody-producing cells.
- Astaxanthin prevents the initiation of cancer cells in the tongue, oral cavity, large bowel, bladder, uterus, and breast.
- Astaxanthin inhibits lipid peroxidation that causes plaque formation, thus reducing risk of cardiovascular disease.
- It alleviates stress and may assist in neurodegenerative conditions such as AMD, Alzheimer’s, Parkinson’s, ALS.Astaxanthin protects the eyes and skin from UV A and B damage by quenching singlet and triplet oxygen.
- Astaxanthin reduces the number of new and abnormal cells in the liver.Some studies show that astaxanthin keeps cataracts away.
