I have been able to reduce my GERD med since taking probiotics. Yogurt, kefir and the like may be a better form, but I have been very happy since taking Enzymatic Therapy’s Pearls.
Buy yourself some ‘kefir grains’ and brew your own kefir for nothing more than the price of milk- it will be orders of magnitude stronger than probiotic supplements, there’s simply no way that supplements can stay as potent.
