Vitamin B1, also known as Thiamine. It's small but mighty—crucial for converting food into energy and keeping your nervous system and brain in top form.

Vitamin B1

✅ What Is Vitamin B1?

Vitamin B1 is a water-soluble B-complex vitamin. Your body uses it to convert carbohydrates into energy and to support proper function of the nerves, muscles, and brain.

Since it’s water-soluble and not stored in large amounts, you need to get it regularly from food.

🔋 What Does B1 Do in the Body?

⚙️ 1. Energy Metabolism

  • Helps convert glucose (from food) into ATP (cellular energy)

  • Works as a coenzyme in key metabolic pathways

🧠 2. Nervous System Function

  • Supports nerve signal transmission

  • Maintains proper muscle coordination and reflexes

  • Important for mental clarity, memory, and mood

❤️ 3. Heart & Muscle Support

  • Aids in muscle contraction, including the heart

  • Helps prevent fatigue and weakness

⚠️ Signs of Thiamine Deficiency

  • Fatigue and irritability

  • Poor concentration or memory

  • Tingling or numbness in hands and feet

  • Muscle weakness

  • Loss of appetite

  • In severe cases:

    • Beriberi (affects heart and nerves)

    • Wernicke-Korsakoff syndrome (linked to alcohol abuse and brain damage)

Alcohol abuse is a major risk factor for B1 deficiency, as it impairs absorption and increases loss.
