COMPARISON BETWEEN IRRADIATION OF DIET AND SUPPLEMENTAL IRRADIATION OF ANIMALS IN VITAMIN A AND D DEFICIENCY
Summary
Daily irradiation and Vitamin D supplementation stimulated animal growth for 10 days. Further research is needed to understand the long-term effects of these vitamin D interventions.
Area of Science:
- Nutritional Science
- Biochemistry
Background:
- Vitamin D is crucial for various physiological processes.
- Ergosterol is a precursor to Vitamin D.
Purpose of the Study:
- To investigate the effects of supplemental Vitamin D and daily irradiation on animal subjects.
- To determine the duration of the stimulating effects observed.
Main Methods:
- Two groups of animals were used: Lot 1 (irradiation + Vitamin D) and Lot 2 (Vitamin D only).
- Lot 1 animals received daily irradiation (except Sundays) for 30 seconds using a Macbeth carbon arc lamp.
- Both lots received supplemental Vitamin D in the form of irradiated ergosterol.
Main Results:
- The animals receiving both Vitamin D and daily irradiation showed apparent stimulating effects.
- These effects lasted for approximately 10 days before beginning to subside.
- Animals receiving only supplemental Vitamin D served as a control for the irradiation component.
Conclusions:
- Combined Vitamin D supplementation and daily irradiation have a temporary stimulating effect on animal subjects.
- The observed effects diminish after approximately 10 days.
- Further studies are warranted to explore sustained benefits and underlying mechanisms.

Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
