A to Z Nutrients Vitamin B-1 (Thiamine) is necessary for
carbohydrate metabolism. It helps maintain a healthy nervous
system, stabilizes the appetite, and stimulates growth and good
muscle tone. It can reduce the negative effects of drinking, by
helping to eliminate acetylaldehyde, the major toxic by-product
of alcohol ingestion. Signs of deficiency include:
gastrointestinal problems, fatigue, loss of appetite, and heart
disorders. Recommended amounts (to avoid deficiency disease, not
for optimal health): Infants: 0.3 - 0.5 mg; Children: 0.7-1.2
mg; Men: 1.4 mg; Women: 1.0 mg. There is no known oral toxicity.
Vitamin B-2 (Riboflavin) is necessary for carbohydrate, fat, and
protein metabolism. It helps form antibodies, red blood cells,
and to maintain cell respiration. Signs of deficiency include
eye problems, cracks and sores in mouth, dermatitis, retarded
growth, and digestive disturbances. Recommended amounts (to
avoid deficiency disease, not for optimal health): Infants: 0.4
- 0.6 mg; Children: 0.8 - 1.4 m
