Maximum doses for Vitamin B

Vit B1 (Thiamine)	·         lack of reports of adverse effects from high thiamin intakes (50 mg/day or more) ·         Higher doses used in Wernicke-Korsakoff syndrome (200-600mg) ·         rapid decline in absorption of thiamin at intakes above 5 mg ·         excessive intakes of thiamin could have adverse effects
Vit B2 (Riboflavin)	·         have no observable toxicity, possibly because riboflavin's solubility and capacity to be absorbed in the gastrointestinal tract are limited ·         higher doses have been used for management of migraine (200-400mg) ·         adverse effects from high riboflavin intakes from foods or supplements (400 mg/day for at least 3 months) have not been reported
Vit B12 (Cyanocobalamin)	·         low potential for toxicity ·         doses from 400-1000 mcg had been used without any adverse events
