B1

  • All Known Essential Vitamins

    Vitamins are a group of substances that are needed for normal cell function, growth, and development. There are 13 essential vitamins:

    • Vitamin A (retinol, retinal, 4 carotenoids)
    • Vitamin C (ascorbic acid)
    • Vitamin D (D3 - Cholecalciferol, D2 - Ergocalciferol)
    • Vitamin E (tocopherols, tocotrienols)
    • Vitamin K (phylloquinone, menaquinones)
    • Vitamin B1 (thiamine)
    • Vitamin B2 (riboflavin)
    • Vitamin B3 (niacin)
    • Vitamin B5 (pantothenic acid)
    • Vitamin B6 (pyridoxine, pyridoxal, pyridoxamine)
    • Vitamin B7 (biotin)
    • Vitamin B9 (folic acid)
    • Vitamin B12 (cyanocobalamin)

    Fat-soluble vitamins are stored in the body's fatty tissue: vitamins A, D, E, K

    Water-soluble vitamins - the body must use almost all water-soluble vitamins right away - vitamins B1, B2, B3, B5, B6, B7, B9 and C.
    Vitamin B12 is the only water-soluble vitamin that can be stored in the liver for many years.

  • Vitamin B1 Thiamine

    Vitamin B1 (Thiamin, Thiamine) is one of 8 B vitamins, the first B vitamin discovered. All B vitamins help the body convert carbohydrates into glucose, which the body uses to produce energy, B-complex vitamins also help the body metabolize fats and protein. All B vitamins are water soluble.

    All living organisms use thiamine, but it is synthesized only in bacteria, fungi, and plants. Animals must obtain it from their diet, therefore for humans it is an essential nutrient.  Your body needs it to form adenosine triphosphate (ATP), which every cell of the body uses for energy.

    B1 helps convert food into energy, needed for healthy skin, hair, muscles, and brain. 

    Thiamine deficiency has a potentially fatal outcome if it remains untreated. In less-severe cases, nonspecific signs include malaise, weight loss, irritability and confusion.

    Recommended daily amount: 1.1 - 1.2 mg (~ 50 g of flaxseeds, or sesame tahini, or 100 g pine or sunflower seeds, or corn flour).

Isaac Bashevis Singer

What do they know-all these scholars, all these philosophers, all the leaders of the world - about such as you? They have convinced themselves that man, the worst transgressor of all the species, is the crown of creation. All other creatures were created merely to provide him with food, pelts, to be tormented, exterminated. 

Estimated Average Requirement EAR

Estimated Average Requirement (EAR) is the average daily nutrient intake level that is estimated to meet the requirements of half  - 50% - of the healthy individuals in a particular life stage and gender group. 

Because the needs of the other half of the population will not be met by this amount, the EAR is increased by about 20% to arrive at the RDA.

Before setting the EAR, a specific criterion of adequacy is selected, based on a careful review of the literature. When selecting the criterion, reduction of disease risk is considered along with many other health parameters.
