This question is probably best for Mark. But figured i would post for all in case others also wonder about how much is too much B vitamins. I bought a time released extra strength high potency B complex. the ingredients are as follows:
Vit B1 150mg 10,000%
Vit B2 150mg 8,000 %
Niacin 150 mg 750%
Vitamin B6 150 mg 7,500%
folic acid 800 mcg 200%
vitamin b12 (cyanocobalamin) 160mcg 2,667%
biotin 160mcg 53%
Pantothenic acid 150mg 1500%
Choline 150mg
Inositol 100mg
PABA 25 mcg
GABA 200mg
Are these doses too high or is it appropriate because not all of these vitamins absorb as easily as the IV forms? Is there a chance of toxicity with this preparation or side effects i should be aware of?
