Vitamins

2.5K
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...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

7.9K
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...

Mineral, Vitamin and Water Absorption01:27

Mineral, Vitamin and Water Absorption

1.6K
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

5.5K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants01:18

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

2.4K
Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Area of Science:

  • Nutritional Science
  • Public Health
  • Endocrinology

Background:

  • Vitamin D, a fat-soluble vitamin, is crucial for human health.
  • Vitamin D deficiency is a global health concern with widespread implications.
  • Beyond skeletal health, emerging research links deficiency to various non-skeletal conditions.

Purpose of the Study:

  • To review and synthesize existing literature on Vitamin D status in India.
  • To elucidate the prevalence and scope of Vitamin D deficiency within the Indian population.
  • To highlight the potential health burden associated with widespread deficiency.

Main Methods:

  • Systematic literature review of studies on Vitamin D status in India.
  • Analysis of reported prevalence rates across different demographics and age groups.
  • Synthesis of evidence on non-skeletal health consequences.

Main Results:

  • Prevalence of Vitamin D deficiency in India ranges widely from 40% to 99%.
  • Most studies indicate a high prevalence, often between 80% and 90%.
  • Deficiency is observed across all age groups and identified high-risk populations.

Conclusions:

  • Vitamin D deficiency represents a significant public health challenge in India.
  • The Indian diet inadequately meets the daily Vitamin D requirements.
  • Urgent need for public awareness, healthcare provider education, and food fortification programs to combat this silent epidemic.
