ROLE IN ANTI-AGING:
Known as the "morale" vitamin, vitamin B1 converts carbohydrates (sugar) into energy, promotes growth, aids digestion, and is essential for nerve tissues, muscle, and heart. It also plays a vital role in the functioning of some important enzymes and is essential for the transmission of certain nerve signals between the brain and the spinal cord. Vitamin B1 helps repel insects and mosquitoes and is used in the treatment of alcoholics and drug addicts.
Vitamin B1 deficiency causes the condition beri-beri which includes mental illness, paralysis of some eye muscles, foot drop, and decreased sensation in the feet and legs. Other symptoms of deficiency include: loss of appetite; fatigue; weakness; neuritis; muscle atrophy; head pressures; poor sleep; feeling tense and irritable; aches and pains; subjectively poor memory, difficulty concentrating; constipation; impaired growth; "pins and needles" sensation in the toes and "burning" sensation in the feet. Alcohol consumption interferes with absorption of B1.
