Vitamins are broken down into their active forms in the body, such as retinol for vitamin A or ascorbic acid for vitamin C. These active forms can then be utilized by the body for various physiological functions.
Amino acids help in the absorption and utilization of vitamin supplements by assisting in the transport of vitamins across cell membranes and supporting the conversion of vitamins into their active forms within the body.
Calcitriol
Vitamin A1 is the most common form of vitamin A found in animal sources like eggs and liver, while vitamin A2 is found in smaller amounts in dairy sources like milk and certain types of cheese. Both forms can be converted to the active form of vitamin A (retinol) in the body, but vitamin A2 is believed to have a slightly different absorption rate and metabolic fate compared to vitamin A1.
Your body gets vitamin A from food sources such as liver, carrots, butter, egg, milk, and many more. In these foods there are the many forms of vitamin A. Some forms include Retinol, alpha-carotene, beta-carotene, as well as 2 or 3 more carotenes. Your body does not make vitamin A; it absorbs it.

No - Vitamin D is not a sugar. The various forms of Vitamin Ds are involved in the regulation of the calcium and phosphorous levels within the body.
No, acetic acid is a weak acid commonly found in vinegar, while vitamin C is an essential nutrient known as ascorbic acid. They are chemically different compounds with different functions in the body.
The kidneys convert vitamin D to its active form, which is known as calcitriol. This active form of vitamin D plays a key role in regulating calcium levels in the body, promoting bone health and supporting other important bodily functions.
Vitamin A is a fat-soluble vitamin that exists in different forms, including retinol, retinal, retinoic acid, and provitamin A carotenoids. Retinol is the form of vitamin A that is most easily absorbed by the body and is found in animal-based foods such as liver, egg yolks, and dairy products.
Nutrients such as calcium, can keep your bones and teeth strong. Another example is Vitamin A. This vitamin helps your eyes. Different nutrients cam help your body in different ways. (Function easier)
The active form of vitamin D is called calcitriol. It is produced in the kidneys from its precursor, calcidiol, which is formed in the liver. Calcitriol plays a crucial role in regulating calcium and phosphorus levels in the body.
