Vitamin A is essential for normal growth, reproduction, immunity, and vision. The characterization of vitamin A spanned a period of about 130 years. During this long, incremental process, there is no single event that can be called the ‘discovery’ of vitamin A. The physiologist François Magendie conducted nutritional deprivation experiments with dogs in 1816 that resulted in corneal ulcers and high mortality – a finding similar to the common clinical situation in poorly fed, abandoned infants… Expand
Introduction: The Diverse and Essential Biological Functions of Vitamins
TLDR
One hundred years ago, in 1912, the Polish-American scientist Casimir Funk coined the term ‘vitamine’ to describe a group of bioactive substances the authors now know to be essential for human health – a pivotal discovery that has contributed to a century of innovative research and improved health.

Vitamins, Biopigments, Antioxidants and Related Compounds: A Historical, Physiological and (Bio)technological Perspective
In hindsight, the history of organic compounds that are now called vitamins can be traced back to the ancient Egyptians; they experienced that feeding animal liver to a person would help cure nightExpand
How Dietary Deficiency Studies Have Illuminated the Many Roles of Vitamin A During Development and Postnatal Life.
TLDR
This chapter begins with a review of representative historical and current studies that used the nutritional vitamin A deficiency research model to gain an understanding of the many roles vitamin A plays in prenatal and postnatal development and well-being. Expand
Does a carrot a day keep the allergy away?
TLDR
Findings from nutritional and clinical trials suggest that sufficient vitamin A supplementation in pregnancy prevents the development of allergic diseases in the offspring, and helps in controlling symptoms in adult asthmatics. Expand
Considering The Role of Vitamin A in Glucose Metabolism
Vitamin A as an essential micronutrient is needed for multiple physiological processes. The association between this nutrient and glucose metabolism has been documented in numerous studies withExpand
CLINICAL AND LABORATORY EVALUATION OF VITAMIN A AND BETA CAROTENE IN LOCAL SHEEP BREED OF BASRA, BASRA_ IRAQ
TLDR
Results showed that local sheep suffer from hypo vitaminosis A with mean level of 1.8 nmol/l, however according to regions of Basrah deficiency of vitamin A and carotenes respectively were indicated of center of Basra. Expand
Vitamin C biochemistry: From scurvy to COVID-19 treatment
The story of vitamin C (L-ascorbic acid) as an antioxidant and a cofactor in numerous biochemical reactions is a part of its long history and it is well known today. However, many questions of itsExpand
A brief history of poultry nutrition over the last hundred years
TLDR
Poultry nutrition is now a scientifically mature subject but changes in industrial practice can be expected to continue, though probably at a slower pace than in recent years. Expand
Role of Vitamin A/Retinoic Acid in Regulation of Embryonic and Adult Hematopoiesis
TLDR
Vitamin A may facilitate iron absorption and metabolism to prevent anemia and plays a key role in mucosal immune responses, modulating the function of regulatory T cells, and the consequences of vitamin A deficiency for the blood system. Expand
Vitamin A and inflammatory bowel diseases: from cellular studies and animal models to human disease
TLDR
This review aims to show the potential role of this vitamin in IBD, searching for cellular studies, animal models, and studies with humans to establish the precise mechanisms of VA and its metabolites in systemic and intestinal inflammation. Expand

Feeding experiments illustrating the importance of accessory factors in normal dietaries
TLDR
The experiments described in this paper confirm the work of others in showing that animals cannot grow when fed upon so-called " synthetic " dietaries consisting of mixtures of pure proteins, fats, carbohydrates, and salts, but show further that a substance or substances present in normal foodstuffs can secure the utilization for growth of the protein and energy contained in such artificial mixtures.
