Thiamin

The anti-stress vitamin

Why we need it

  • Thiamin, also known as vitamin B1, improves our bodies ability to handle and manage stress by strengthening the immune system1*
  • Like all B complex vitamins, thiamin plays a key role in your metabolism and energy production*
  • Supports a healthy brain and nervous system along with healthy hair, liver, and skin2*
  • May lower the risk of developing cataracts when in combination with protein and vitamins A, riboflavin, and niacin3,4*

How much do I need?

The current recommended daily intake (RDI) for thiamine is5:

  • Newborns, 6 months: 0.2 mg
  • Infants, 7 months to 1 year: 0.3 mg
  • Children, 1 to 3 years: 0.5 mg
  • Children, 4 to 8 years: 0.6 mg
  • Children, 9 to 13 years: 0.9 mg
  • Men, 14 to 18 years: 1.2 mg
  • Women, 14 to 18 years: 1 mg
  • Men, 19 years and older: 1.2 mg
  • Women, 19 years and older: 1.1 mg
  • Pregnant or breastfeeding women: 1.4 mg

Why we include it

The B complex vitamins help the body convert food into energy in the form of glucose and utilize fats and proteins. They are essential for a healthy nervous system and healthy skin, eyes, and hair. Although a thiamin deficiency is rare in the U.S., it’s such a vital vitamin that we’ve included it in all of our multivitamin products to ensure you’re getting adequate levels of this nutrient. Since all B complex vitamins are water-soluble, your body will simply eliminate any it doesn’t use.
