Vitamin B1 (Thiamin)

Thiamin is crucial for energy metabolism for cell growth, development and function.

100% grapefruit juice supplies thiamin, providing 8% of the Daily Value in a 250 ml serving. Smaller amounts can be found in a serving of whole grapefruit (1/2 medium) (4% DV).

  • Eat grapefruit for energy! They deliver thiamin, a water-soluble B vitamin that is associated with the action of many of the body’s enzymes and the conversion of food into energy.1,2
  • Very little thiamin is stored in the body, and because it is used up quickly, frequent consumption of thiamin from the diet is necessary.1,2
