Vitamin B1
Vitamin B1 plays a central role in energy production and supports the nervous system. When levels are low, it may manifest as weakness, low motivation, difficulty concentrating, or general fatigue. It is one of the vitamins that helps maintain mental clarity and a stable sense of vitality.
Digestive health strongly influences how well the body absorbs B1. When the digestive system is stressed or inflamed, uptake may be affected. Because of its connection to the nervous system, signs of imbalance often appear as low energy or reduced cognitive sharpness.
