Body storage of thiamine is minimal. https://www.who.int/nutrition/publications/en/thiamine_in_emergencies_eng.pdf https://www.who.int/nutrition/publications/en/thiamine_in_em... >> Body storage of thiamine is minimal, the liver being the main extra-muscular storage site. In young and healthy non-alcoholic individuals, subjective symptoms appear after 2 to 3 weeks of a deficient diet (Brin,1963). Characteristic early symptoms include anorexia, weakness, aching, burning sensation in hands and feet, indigestion, irritability and depression. After 6 to 8 weeks the only objective signs at rest may be a slight fall in blood pressure, and moderate weight loss. After 2 to 3 months apathy and weakness become extreme, calf muscle tenderness develops with loss of recent memory, confusion, ataxia and sometimes persistent vomiting (Anderson et al,1985).
