There are a number of products on the market that are advertised as Effervescent C.
They typically consist of a powder or tablet that dissolves in water to create a fizzy drink.
Is there any data to indicate that consuming Vitamin C in a fizzy drink is any better than just taking a Vitamin C pill?
Effervescent pills have the advantage that since you ingest the active compount already dissolved the absorption rate is generally faster than for normal pills. This is useful when you need the drug to kick in as soon as possible, like medicines for pain or fever. In the case of vitamin C, I see little to no reason why you would need such a fast action, so I assume that there is no benefit on taking one over the other.
