Resumen

Las deficiencias de vitaminas pueden causar problemas en las uñas, pero la evidencia que respalda los suplementos vitamínicos para la salud de las uñas es limitada. La suplementación puede no ser beneficiosa y conlleva riesgos potenciales.

Área de la Ciencia:

Dermatología
Ciencia de la Nutrición

Sus antecedentes:

Las uñas son apéndices cutáneos especializados con funciones protectoras y estéticas.
Las vitaminas son cruciales para el crecimiento y la función corporal, y las deficiencias pueden manifestarse en las uñas.
La evidencia actual sobre la suplementación vitamínica para la salud de las uñas es limitada y a menudo inespecífica.

Objetivo del estudio:

Revisar el papel de la suplementación vitamínica en la salud de las uñas.
Evaluar la eficacia y los riesgos asociados con los suplementos vitamínicos para los trastornos de las uñas.

Principales métodos:

Revisión de literatura sobre deficiencias vitamínicas y manifestaciones ungueales.
Análisis de estudios que investigan la suplementación con biotina y vitamina E para la salud de las uñas.

Principales resultados:

Las deficiencias de vitaminas pueden causar cambios en las uñas fácilmente reconocibles pero inespecíficos.
Existe evidencia limitada y robusta que respalda la suplementación vitamínica para la salud general de las uñas o la apariencia de uñas enfermas.
La biotina y la vitamina E han mostrado resultados variables en los trastornos de las uñas.

Conclusiones:

El papel de la suplementación vitamínica en la mejora de la salud general de las uñas carece de evidencia sustancial.
El uso indiscriminado de suplementos para la salud de las uñas puede no ser uniformemente beneficioso y presenta riesgos.

Role of Vitamins in Maintaining Bone Health

Role of Vitamins in Maintaining Bone Health

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...

Vitamins

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...

Accessory Structures of the Skin: Nails

Accessory Structures of the Skin: Nails

Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Role of Skin in Vitamin D Synthesis

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...

Mineral, Vitamin and Water Absorption

Mineral, Vitamin and Water Absorption

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...

Health Literacy

Health Literacy

Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...
