Hi there. Thank you for your question. I will be helping you out with your queries
Yes you can safely take the two together without any problems.
Even though there are overlapping vitamins in both of them but they should not cause any problems as they still fall in the therapeutic dose range.
However I would prefer you taking either one or the other than taking both because of the very fact that there are a few overlapping vitamins.
Let me know if you have any further questions.
Rate me for my services when you are done asking.
Thank you for the quick reply. The reason for my question is because several internet sources suggest that taking too high doses of B vitamins over a period of time can be damaging for the body, particularly the nerves. Is that so?
