If she has an over Acid stomach or an under acid stomach, she may take the ACV and some Blackstrap Molasses with it and may help correct both problems!
And "IF" she would include some Lime water and kelp powder, these may further help in solving the problems!
Too much acids in the stomach may just be, because the body is not getting enough Alkaline Minerals from the foods you eat and the stomach is trying to make up for this short fall by increasing the Acids, in hope of extracting more Alkaline Minerals for the body to have for use!
Not all is as it may first seem to be!
As she learns about that she may be very short of the needed Alkaline Minerals to keep her healthy, and she may make a choice to start supplying what her body may be Lacking, then she may see direct Positive results, in Direct amount to her efforts to do what she needs to do to solve this problem!
