I am unclear on how much xylitol one should consume daily. At first I thought you were recommending 6.5-10 grams per day which would mean 13 mints in one day to meet the 6.5 gram requirement... Though you say online to consume at least 6.5 grams 5 times per day. So, that would mean someone would need to eat 13 mints at once 5 times per day? Which is correct? Are dosages different for kids vs. adults?
Initially studies suggested the imporance of having ENOUGH xylitol each day. There was a study in 2001 that told us it was important to have between 6.5 and 10 grams a day.
NEW RESEARCH, since then, indicates FREQUENCY may be more important. Now we suggest you try to have at least 5 exposures to xylitol each day.
In other words, putting two teaspoons of xylitol (10 grams) into ONE cup of tea probably will not help you ....BUT the same amount, eaten as 2 grams x 5 times a day would work well ! Xylitol is best after meals and snacks.
I usually suggest you think how many times a day you eat or snack.
I have 3 meals a day and 4 snacks.
I usually have one gram of xylitol after everything I eat or drink = 7 times a day.
(This is usually two Zellies mints or sometimes a piece of gum).
This means that at the end of the day I have had 7 grams of xylitol total - (by having 7 x one gram exposures).
More than this is safe- but more than 10 grams a day will not make your teeth any stronger or healthier ( according to the studies). The studies showed that at 10 grams a day there are no more benefits for teeth!
This is called the palateur effect.
Hope this answers the question and clarifies the dosage! For smaller children I would focus on frequency - and not worry too much about the total amount. For infants, wiping the childs teeth would be counted as an exposure.
