  1. Description

    B1 thiamine contains vitamin B1, a vitamin of the B complex that contributes to the normal functioning of the nervous system, to the normal functioning of the heart, to normal psychological functioning, as well as to the normal functioning of metabolic processes aimed at the production of energy.

    Sources of thiamine include foods such as whole grains, rice, whole wheat bread, beans, peas, peanuts and whole grains. Thiamine plays an important role in maintaining the health of the nervous system. It helps to transfer electrical impulses to the brain, improving the functioning of neurons. In addition, it contributes to the production of neurotransmitters, that are necessary for the transmission of stimuli between neurons.

  3. Benefits

    Most cells in the body use vitamin B1 for various functions. It also participates in metabolism, i.e., the conversion of food into energy. The human body cannot synthesize vitamin B1 alone, so it must be obtained through diet or supplementation.

    People with more significant needs for vitamin B1 are:

    • People who regularly consume alcohol
    • Elderly
    • People with HIV/AIDS
    • Diabetics
    • People with dementia or Alzheimer's disease
    • People with depression
    • Obese people

    Although symptoms of thiamine deficiency were first recorded in ancient Chinese medical texts, the symptoms were not linked to diet until the late 19th century.

    In 1884, a Japanese doctor noticed high rates of disease and death among Japanese sailors who followed a limited diet of only rice for months while at sea. When given a more varied diet of whole grains, meats, beans, and vegetables, disease and death rates nearly disappeared.

    Around the same time, two Dutch scientists noticed that chickens that fed white polished rice developed leg paralysis, while chickens fed brown unpolished rice did not. Their observations led to the discovery of thiamine in the outer layers of rice that were removed by polishing.

    Some symptoms of vitamin B1 deficiency are:

    • loss of appetite
    • irritability
    • muscular weakness
    • fatigue
    • reduced reflexes
    • numbness in the extremities
    • headaches
    • motion sickness
