Vitamin Supplements
Vitamin supplements are pills, capsules, powders, or liquids that contain one or more vitamins, which are organic compounds that the body needs in small amounts for normal growth and development.
Pronunciation
- Vitamin: /ˈvɪtəmɪn/
- Supplements: /ˈsʌplɪmənts/
Etymology
The term "vitamin" comes from the Latin word "vita," meaning life, and the chemical suffix "-amine," because vitamins were initially thought to contain amines. The term "supplement" comes from the Latin word "supplementum," which means something added to complete a thing or make up for a deficiency.
Types of Vitamin Supplements
There are two main types of vitamin supplements: water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins, which include vitamin C and the B vitamins, need to be consumed more frequently because they are not stored in the body. Fat-soluble vitamins, which include vitamin A, vitamin D, vitamin E, and vitamin K, are stored in the body's fatty tissue and liver, and are used as needed.

Health Benefits and Risks
