🧩Application of Fursultiamine CAS No.: 804-30-8

1. Clinical Medical Applications

Vitamin B1 Deficiency-Related Disorders

It is used to treat all types of beriberi, and relieve fatigue, lower limb edema, palpitations, poor appetite, intestinal flatulence and indigestion caused by vitamin B1 deficiency.
