| Irving,
Vitamin B is good, but like anything--in moderation. It is not recommended to take more than daily dosage, because like any water-soluble vitamins, it gets dissolved quickly in your body and natural defenses of your digestive and urinary system eliminate all extras (that's why some people notice color changes in their urine). So I suggest to take no more than 200 micrograms daily (combination of thiamin (B1), riboflavin(B2), folate, and niacin (B3)). B12 dosage is microscopic, so if you eat your green leafy vegetables, you get the amount needed.
