Types of Vitamin A

In general, there are 2 types of vitamin A.
Provitamin A sources
– Sweet potatoes
– Carrots
• Vitamin A from animal-derived foods is named retinol.
• This “pre-formed” vitamin A can be utilized directly by the body. Good sources of retinol vitamin A foods include:
– beef liver
– chicken liver
– cheese
• Vitamin A from colorful vegetables and fruit is in the form of “provitamin A” carotenoids.
• These are transformed into retinol in the body after your meals are ingested. Good food sources of provitamin A carotenoids include:
– carrots
– sweet potatoes
– spinach
– kale
– cantaloupes
• Beta carotene is probably the most prevalent and effective provitamin A carotenoids.

Eye booster factors about Vitamin A and Beta Carotene

• As vitamin A shields the eye surface also known as cornea, it is very essential for vision.
• Research has revealed vitamin A eye drops seem to cure the dry eyes.
• In fact, one study found that over the counter lubricating eye drops have lesser effect that vitamin A drops.
• They are more effective for the treatment of dry eye syndrome than the expensive prescription eye drops formulated for dry eye relief.
• Vitamin A eye drops have demonstrated capability that is effective with the therapy for eye inflammation called superior limbic keratoconjunctivitis.
• Vitamin A, even in a combination with other antioxidant vitamins, appears to play a role in decreasing the risk of macular degeneration (AMD).
• In landmark Age-Related Eye Disease Study (AREDS) sponsored through the National Eye Institute, people who were at higher risk to the disease and took a day-to-day multiple vitamin were seen to have a 25% reduced risk of advanced AMD in a six-year period.
• The multiple vitamin combination has:
– vitamin A (as beta carotene)
– vitamin C
– vitamin E
– zinc
– copper
• In addition, it appears that a mixture of vitamin A and lutein may improve vision in people affected by retinitis pigmentosa (RP).
• A recent 4-year research carried out by the scientists from Harvard Medical School and some prominent universities revealed that men and women who have retinitis pigmentosa and also took regular supplements of vitamin A and lutein have a slower paced loss in peripheral vision when compared to people who do not take the combined supplements.
• Because beta carotene is converted into vitamin A within the body, it’s likely beta carotene (provitamin A) which offers eye benefits since the pre-formed retinol type is of A vitamin. However, more studies are necessary to confirm this.
• In the beginning of 2011, researchers at Columbia University Hospital (New York) found that a synthetic, altered type of vitamin A could possibly slow the progression of Stargardt’s disease.
• This is an inherited eye disease that causes severe vision loss in teenagers.
