Every tissue in your body needs vitamin B1 to function. Your body doesn’t produce this essential B vitamin on its own.
Especially Important For
People who have a poor diet*, Chronic Fatigue Syndrome*, Crohn's Disease*, anorexia*, alcoholism*, a weakened immune system*, cataracts*, “morning sickness” during pregnancy*, and/or people who have recently had bariatric surgery.*
Why it's important for hydration
Vitamin B1 is a key component to helping electrolytes flow in and out of cells. It also supports proper functioning of your nervous system, muscles and major organs like your brain, heart and stomach.
Why it's important for overall health
It’s used by nearly all your cells and is responsible for converting food into energy.
Fatigue and a lack of energy are two of the most common symptoms of vitamin B1 deficiency. There’s a bevy of research linking the two.
Low vitamin B1 levels commonly result in irritable moods.
Scientists have also looked at thiamine as a possible treatment for cataracts, kidney disease and potentially Alzheimer’s.
