Major Dietary Precursor For Vitamin D Synthesis

Calcitriol is the vitamin d precursor produced in the dermal capillaries that aid calcium absorption.

Major dietary precursor for vitamin d synthesis. The average apple has 8 4 mg of vitamin c. Vitamin d is a group of fat soluble secosteroids responsible for increasing intestinal absorption of calcium magnesium and phosphate and many other biological effects. Approximately 10 15 minutes twice a week is necessary for vitamin d synthesis.

Fruits are a major dietary source of vitamin c. 290 315 nm radiation and from dietary intake. The cutaneous synthesis of vitamin d is a function of skin pigmentation and of the solar zenith angle which depends on latitude season and time of day.

The major natural source of the vitamin is synthesis of cholecalciferol in the lower. Vitamin d 2 found in plants and better known as ergocalciferol or calciferol and vitamin d 3 found in animal tissues and often referred to as cholecalciferol both of these compounds are inactive precursors of potent metabolites and therefore fall into the category. Some high vitamin c fruits include orange papaya cantaloupe and raspberries.
