Vitamin C is a water-soluble vitamin that is used in many tissues throughout the body. The adrenal gland contains the highest concentration of vitamin C, and the vitamin plays a crucial role in both the adrenal cortex and adrenal medulla [1]. Humans are one of the few species that cannot manufacture the vitamin in the body and must depend on diet or nutritional supplementation as a source of vitamin C. The best sources of vitamin C are fresh fruit (especially in the citrus family, including oranges, lemons, limes and tangerines), strawberries, cantaloupe and currants. Green leafy vegetables, including Brussel sprouts, collard greens, lettuce, cabbage, peas and asparagus, are also good sources.
The Best Way to Stay Healthy and Avoid Getting Sick
The best way to stay healthy and avoid getting sick is to wash your hands. Some of the most recent scientific evidence comes from a study of hospital-acquired methicillin-resistant Staphylococcus aureus infection. Methicillin-resistant Staphylococcus aureus (MRSA or “staph”) is a bacteria that can enter the body through breaks in the skin and cause severe infections and even death, especially in people who are already sick. MRSA represents a major control problem in hospitals as it has developed a resistance to all penicillins, including methicillin and other narrow-spectrum beta-lactamase-resistant penicillin antibiotics [1]. Researchers concluded at the end of the study that hospitals could greatly limit the spread of MRSA through the use of increased barrier protection (gloves) by workers and more frequent hand washing [2].
Vitamin B
Vitamin B is a complex of eight water soluble vitamins active in cell metabolism. They include Thiamine (vitamin B1), Riboflavin (vitamin B2, also called vitamin G), Niacin (vitamin B3, also called vitamin P), Pantothenic acid (vitamin B5), Pyridoxine and Pyridoxamine (vitamin B6), Biotin (vitamin B7, also called vitamin H), Folic acid (vitamin B9, also called vitamin M) and Cyanocobalamin (vitamin B12).
Note: This review is not meant to be a comprehensive or definitive glossary, but rather to identify each vitamin’s function and highlight recent research findings of each of the B vitamins.
Amino Acids
Amino acids are organic compounds containing an amino group (NH2), a carboxylic group (COOH) and any of various side chain groups. There are twenty amino acids encoded by the genetic code, referred to as the standard amino acids. The basic components of proteins, amino acids form short polymers (meaning a long molecule made up of a chain of smaller, simpler molecules) called peptides or longer polymers called polypeptides or proteins. Additionally, amino acids can function as chemical messengers and as intermediates in metabolism.
Vitamin A
Vitamin A consists of a group of compounds that play an important role in vision, bone growth, reproduction, cell division and cell differentiation [1]. It helps to regulate the immune system and may also help lymphocytes (meaning a type of white blood cell) better fight infection [2].
