In brief
WebMD defines key terms for understanding vitamins, minerals, herbs and how supplements work in your body. A glossary explains vitamin and supplement terminology, covering amino acids, antioxidants, fat and water-soluble vitamins, minerals, and regulatory standards. Originally reported by WebMD.
Amino acids build proteins
Humans need twenty-one different amino acids to function properly. Some are made by the body, while others called essential amino acids must be obtained from foods.
Antioxidants fight free radicals
Antioxidants like vitamins A, C, E and beta-carotene protect your body from damage caused by free radicals, unstable atoms or molecules with unpaired electrons that interfere with cell function.
Fat-soluble vitamins store in body
Fat-soluble vitamins are A, D, E and K. Your body stores excess amounts in your liver and body fat. Taking more than needed can be toxic, causing nausea, vomiting and liver and heart problems.
Water-soluble vitamins work differently
Water-soluble vitamins like B-six, C and folic acid are easily absorbed by the body. Your body uses what it needs then excretes excess in urine, creating less toxicity risk but greater deficiency risk.
Micronutrients support macronutrient processing
Micronutrients are vitamins and minerals your body needs only in small amounts. They are vital to processing macronutrients like fats, proteins and carbohydrates. Examples include chromium, zinc and selenium.
USP sets supplement standards
The U.S. Pharmacopeia is a nonprofit authority that sets standards and certifies supplements meeting quality, strength and purity standards called Good Manufacturing Practices. Many supplements carry the USP symbol on their label.
