Thiamin (vitamin B1) in VH Life: 1.1mg per sachet, and what it may claim
A VH Life sachet provides 1.1mg of thiamine (100% of the NRV), as thiamine. That is above the 15% of NRV a single-portion food must provide to carry thiamine's authorised claims, so VH Life may use all 4 of them, for example: Thiamine contributes to normal energy-yielding metabolism. Thiamine, or vitamin B1, is a water-soluble B vitamin found in peas, bananas, oranges, nuts, wholegrain bread and fortified cereals.
