Humans need 13 essential letter vitamins to stay healthy and function properly. These vitamins can be divided into two categories: fat-soluble and water-soluble. Fat-soluble vitamins A, D, E, and K are absorbed with the help of lipids through the intestines, while water-soluble vitamins B complex and C dissolve easily in water. Vitamins are essential for the body's growth and development, and they can be found in fruits and vegetables.
The letters (A, B, C, etc.) were assigned to vitamins in the order of their discovery. The only exception was vitamin K, which was assigned by Danish researcher Henrik Dam. WebMD provides a breakdown of the functions of these vitamins, with nine being water-soluble and four being fat-soluble. In 1930, Paul Karrer clarified the correct structure of beta-carotene, the main precursor of vitamin A, and identified other carotenoids.
Vitamin E is particularly important for many body systems, including the heart, lungs, prostate, and digestive tract. It is also a powerful antioxidant that helps protect cells from damage. When choosing a supplement, it is important to consider safety, bioavailability of supply, and overall quality of ingredients. Rainbow Light offers Vibrance Men's Multivitamin plus Stress Support and Vibrance Women's Multivitamin plus Stress Support, both of which are food-based multivitamins containing highly bioavailable full-spectrum B vitamins and magnesium.
DeltaGold contains exclusively delta and gamma-tocotrienols, the most potent vitamin E isomers for most applications. It is important to remember that lifestyle factors such as age, diet, medications, environment and stress can all impact which multivitamin should be consumed. It is also important to be aware of any potential toxicity at higher intakes. With so many options available on the market today, it is important to do your research before choosing a supplement.
