Vitamin B1 250mg is essential for the breakdown of glucose, the brain’s principal source of energy. It plays a role in the maintenance of mood in healthy adults and facilitates the production of acetylcholine, which plays a role in memory. Thiamine is involved in energy production in the body. Vitamin B1 levels can be diminished by the consumption of tea, coffee or alcohol and the elderly may have an additional requirement for this nutrient. Vitamin supplements should not replace a balanced diet. If symptoms persist consult your healthcare professional.
