Most people think of “heartburn” as a “too much stomach acid” problem. This could not be further from the truth. The majority of people with heartburn/acid reflux actually have low stomach acid. This causes food to sit in their stomachs too long because it is slow to digest. They often feel “full” for an extended period of time following meals. Weak/brittle nails are also a side effect of low stomach acid, as well as constipation and food allergies. Natural stomach acid (HCl) is one of the first lines of defect to “kill” incoming bad bacteria. If you don’t have it, you are more likely to get sick.
