The first B-complex vitamin ever to be discovered, vitamin B-1 is also known as thiamine. Like other B-vitamins, thiamine is a water-soluble essential nutrient, meaning the body cannot create its own, nor can it store excess vitamin B-1. Because of this, many food sources such as grain cereals are fortified with thiamine (along with other essential nutrients) to help meet RDAs. Vitamin B-1 can also be found in fish, eggs, lean meats, whole grains and peanuts.
Vitamin B-1 supports healthy functioning of the human body in various ways.** It is perhaps most commonly used to support nervous system health, and in particular it works with other B-complex vitamins to support the body during the occasional stress we all encounter from time-to-time.** This nutrient also works with other B-vitamins to turn carbohydrates and proteins from the foods you eat into energy for the body.**
Vitamin B-1 Supplements
Nutritional supplementation with vitamin B-1 – or any B-complex vitamin – is important, since it’s impossible for the body to produce thiamine on its own. Vegetarians and vegans may benefit from additional vitamin B-1, as it is often found in animal products. Supplements containing vitamin B-1 thiamine are available in several forms including tablets, liquids and capsules.
Benfotiamine B-1 Supplements
A relatively new nutritional supplement trend, benfotiamine is a highly bioavailable, fat-soluble version of B-1. This easily absorbed form is an especially important nutrient for healthy glucose metabolism.** Its advantages in bioavailability may benefit those who have trouble absorbing water-soluble B-1 thiamine.**
Vitamin B-1 Directions for Use
You should never begin taking a vitamin B-1 thiamine supplement, or any other nutritional supplement, without talking to your doctor first. The recommended daily allowance (RDA) for vitamin B-1 is 1.2 mg per day for adult men and 1.1 mg per day for adult women. The most common vitamin B-1 dosage is usually around 100 mg, whether it appears alone or in a B-complex nutritional supplement. Some supplements may supply up to 250 mg of B-1.
