What is Vitamin B1 Deficiency?
Vitamin B1 (Thiamine) is an essential nutrient that helps the body convert food into energy, supports nerve function, strengthens muscles, and maintains a healthy heart and digestive system.

Who Needs More Vitamin B1?
Pregnant women require 5 mg daily throughout pregnancy.
Breastfeeding infants depend on the mother’s Vitamin B1 levels — deficiency causes stomach and heartburn issues.
Hard workers and obese individuals need higher Vitamin B1 due to increased energy usage.
People who eat machine-polished rice or refined wheat are more prone to deficiency.
