Tired body

Depending on the severity of the deficit, vitamin B1 insufficiency produces either gradual weariness (slight loss of energy) or rapid exhaustion (extreme exhaustion). Depending on the severity of the deficit, it might range from a modest reduction in energy to acute weariness. Because weariness is such a broad symptom with numerous different causes, it is frequently missed as a sign of thiamine shortage. Given the importance of thiamine in the conversion of food to fuel, it's not surprising that exhaustion and a lack of energy are prominent signs of thiamine deficiency. According to several research, thiamin deficiency causes fatigue in the body.

Vitamin B1 aids in the metabolism of carbs, proteins, and lipids into ATP, the molecule that transports energy to cells. As a result, vitamin B1 shortage causes metabolic abnormalities; cells are not supplied with enough energy, resulting in exhaustion and weakness.
