Dear Stephanie: You may take it as long as you like.
Apple cider vinegar and baking soda is like a form of nutrition that your body needs, but it not currently recognized. Malic acid component of apple cider vinegar is what gives the body energy. The baking soda the body needs constantly since whenever the body burns fuel, it causes the body to be acidic, as well as most of the foods we do take are also acid forming. It is nice to avoid all the acid forming foods, but it is not practical. Therefore, you may take it as long as you like.
I have been taking this about 35 years and going, but I do not take them everyday, but try to take them whenever I have the occasion to do so, which is most of the time. Two things that I believe are important, lemon (or lime) and baking soda, or apple cider and baking soda. If you are more chemically oriented, it is like vitamin C, potassium citrate, malic acid, and baking soda.
Natural foods have a more broader spectrum of healthy components than do a more purified form. Minerals is also found in apple cider vinegar also.
