Vitamin B1 (Thiamine)
Essential for Energy, Nerves, and Brain Function
Vitamin B1, also known as Thiamine, is a crucial nutrient that enables your body to turn carbohydrates into energy. Because your body cannot produce Thiamine on its own and does not store it for long periods, you rely entirely on your diet to maintain healthy levels.
The Vitamin B1 Blood Test (typically a Whole Blood analysis) measures the level of Thiamine in your system. It is a vital diagnostic tool for unexplained fatigue, confusion, and nerve damage.
Thiamine deficiency is more common than many realize, particularly in specific risk groups. Your doctor may order this test if:
- You have symptoms of Neuropathy: Tingling, numbness, or burning sensations in your hands and feet.
- You experience mental confusion: Brain fog, memory loss, or difficulty walking/balancing.
- You are at high risk for deficiency:
- Alcohol Use: Alcohol blocks the absorption of Vitamin B1, making deficiency very common in heavy drinkers.
- Diabetes: Diabetics often excrete Thiamine faster than non-diabetics.
- Bariatric Surgery: Post-surgery patients often have trouble absorbing nutrients.
- Diuretics: Long-term use of water pills (like Furosemide) can deplete B1 levels.
