Vitamin A Natural by Carlson Labs
Carlson Labs Vitamin A 25,000 IU - 100 Softgels
Carlson Labs Vitamin A 25,000 IU is an essential nutrient in human nutrition. Carlson Labs Vitamin Ais categorized as a fat-soluble vitamin as it is stored in the fatty portions of the body's organs and tissues. Carlson Labs Vitamin A is available in two forms: pre-formed Vitamin A (from fish liver) and Pro Vitamin A (Beta carotene from fruits and vegetables).
Carlson Labs Vitamin A is a fat-soluble vitamin with four major functions in the body: (1) It helps cells reproduce normally-a process called differentiation (cells that have not properly differentiated are more likely to undergo pre-cancerous changes). (2) It is required for vision; vitamin A maintains healthy cells in various structures of the eye and is required for the transduction of light into nerve signals in the retina. (3) It is required for normal growth and development of the embryo and fetus, influencing genes that determine the sequential development of organs in embryonic development. (4) It may be required for normal reproductive function, with influences on the function and development of sperm, ovaries and placenta.
People who limit their consumption of liver, dairy foods, and beta-carotene-containing vegetables can develop a vitamin A deficiency. Extremely low birth weight babies (2.2 pounds or less) are at high risk of being born with a deficiency, and vitamin A shots given to these infants have been reported in double-blind research to reduce the risk of lung disease. The earliest deficiency sign is poor night vision. Deficiency symptoms can also include dry skin, increased risk of infections, and metaplasia (a precancerous condition). Severe deficiencies causing blindness are extremely rare in Western societies.
Less severe deficiencies are more likely to occur with a variety of conditions causing malabsorption. A high incidence of vitamin A deficiency in people infected with HIV has also been reported. People with hypothyroidism have an impaired ability to convert beta-carotene to vitamin A. For this reason, some doctors suggest taking supplemental vitamin A (perhaps 5,000-10,000 IU per day) if they are not consuming adequate amounts in their diet. Very old people with type 2 diabetes have shown a significant age-related decline in blood levels of vitamin A, irrespective of their dietary intake.
For most people, up to 25,000 IU (7,500 mcg) of vitamin A per day is considered safe. However, people over age 65 and those with liver disease should probably not supplement with more than 15,000 IU per day, unless supervised by a doctor. In women who could become pregnant, the maximum safe intake is being re-evaluated. However, less than 10,000 IU (3,000 mcg) per day is generally accepted as safe. There is concern that larger intakes could cause birth defects. Whether the average person would benefit from vitamin A supplementation remains unclear.
Adults take 1 softgel daily at mealtime. Do not exceed recommended dose. Do not take if you are pregnant or plan to beceome pregnant.
Store in a cool, dry place. Keep out of reach of children.
