Question

"how do Caffeine depletes vitamin b? what is the mechanisom?"

thank you

Answer 1

Caffeine stimulates the kidneys and causes an increase in water loss/  dehydration/. This leads to depletion of vitamins, including vitamin B.

Answer 2

B vitamins are water soluble and need to be consumed every day. Caffeine is a diuretic so speeds water loss, which means loss of vitamins, especially C and all the Bs, also some loss of Potassium & trace minerals.
