How long does it take for a liquid vitamin to work?
The time it takes for vitamin intake to work can be hours or weeks, depending on how deficient your body is in that particular supplement. If you are dehydrated, an electrolyte supplement will help you immediately. Calcium, on the other hand, will take 6 weeks to make a difference if you have bone density issues, and calcium requires a lot of other things for your body to truly absorb and reap the benefits.
