Can I take my capsules (rhodiola rosea) with my black tea in the morning?

Do you absolutely need water, if so is it really beneficial to use bottled water instead of tap water (which brand?)? How much liquid: a glass?

Please answer me before tomorrow afternoon, I’m leaving for studies afterwards  

In the meantime I have read some tips that make me give up tea with the supplement so my question is:

Which brand of water is the most recommended to accompany the capsule?

Please answer
