Vitamin A also supports:-
Two forms of vitamin A are available in the human diet: preformed vitamin A (Retinol and its esterified form, retinyl ester) and provitamin A Carotenoids.
Pre-formed vitamin A is found in foods from:-
By far the most important provitamin A carotenoid is beta-carotene.
Provitamin A carotenoids are alpha-carotene and beta-cryptoxanthin.
The body converts these plant pigments into vitamin A. Both provitamin A and preformed vitamin A must be metabolized intracellularly to retinal and retinoic acid, the active forms of vitamin A, to support the vitamin’s important biological functions.
Other carotenoids found in food which does not converted into vitamin A, such as:-
The various forms of vitamin A are solubilized into micelles in the intestinal lumen and absorbed by duodenal mucosal cells. Both retinyl esters and provitamin A carotenoids are converted to retinol, which is oxidized to retinal and then to retinoic acid. Most of the body’s vitamin A is stored in the liver in the form of retinyl esters.
Retinol and Carotenoid levels are typically measured in plasma, and plasma retinol levels are useful for assessing vitamin A inadequacy. However, their value for assessing marginal vitamin A status is limited because they do not decline until vitamin A levels in the liver are almost depleted. Liver vitamin A reserves can be measured indirectly through the relative dose-response test, in which plasma retinol levels are measured before and after the administration of a small amount of vitamin A. A plasma retinol level increase of at least 20% indicates an inadequate vitamin A level. For clinical practice purposes, plasma retinol levels alone are sufficient for documenting significant deficiency.
Warning: Consult your health care practitioner before use if you are pregnant or lactating or if you have hypertension, diabetes, or have had kidney or liver disorders. Discontinue use and consult your health care practitioner if you experience sleeplessness, headache or heart palpitations.
As a fat-soluble nutrient, vitamin A may be more difficult for some individuals to absorb than water-soluble vitamins. Fat-soluble nutrients require a complex series of reactions, involving bile and pancreatic acids, enzymes, and transport proteins for absorption and utilization within the body.
Unfortunately, these body processes may be less efficient in individuals with certain health conditions, and also depend on individual enzyme activity levels and dietary considerations.
To support optimal absorption in light of these challenges, this product provides Vitamin A in Micellizedform, using a unique process to create extremely small, water-soluble arrangements that may be more easily absorbed and assimilated.*
Micellized Vitamin A by Adaptogen Research providing 1,507 mcg RAE (1500 mcg RAE as vitamin A palminate and 7 mcg RAE as beta-carotene (5,025 IU) of vitamin A per single drop.
This important nutrient plays an essential role in healthy immune function and vision, normal growth and development, and the health of skin and mucous membranes.
Vitamin A Drops can be taken by anyone wishing to optimize their vitamin A intake or requiring supplemental vitamin A, especially those who have trouble swallowing traditional pills or capsules.*
Two ways to get Vitamin A - Liquid - or Softgels
