Can you overdose on b12 and b1 vitamins? i take them sublingually

Not really: These vitamins are water soluble and are quickly excreted by the kidneys. On the other hand, fat soluble vitamins like A, D, E and K can accumulate in the fatty tissues and in the case of A&D cause serious illness or death. Thanks for trusting HealthTap!

Can you overdose on vitamin B12? Is it safe to take 16000 mgs

How often?: There are no known illeffects from overdose of vitamin B12, but you would be wasting your medication and money. If you need to take vitamin B12, you should take it as an injection and and injection of 1000 micrograms (not milligrams) each month, is more than enough.
