Though some swear by apple cider vinegar for relieving heartburn or indigestion, taking these tablets too frequently may have the opposite effects. Apple cider vinegar tablets are very acidic, which can lead to severe irritation of the stomach, throat or esophagus. As the tablets dissolve when being swallowed, acid deposits may be left in the throat or esophagus and cause burns and irritation. This acid may also irritate the lining of the stomach and cause discomfort that is similar to heartburn or indigestion.
Chromium is an ingredient found in apple cider vinegar tablets. This ingredient is known for affecting the insulin levels of the body. For diabetics, this can be especially dangerous. When diabetics take these tablets, they may find it even more difficult to keep their insulin levels at a healthy rate. The chromium in these tablets may cause the insulin levels to drop or increase substantially.
Taking apple cider vinegar tablets may also be unsafe for those who suffer from osteoporosis. This supplement can cause a loss of potassium, which may weaken bones. For this reason, it is very important for people with brittle bones to first consult a physician before beginning an apple cider vinegar tablet regimen.
Apple cider vinegar may also interact with certain medications. They may cause those medications to not work properly to control the symptoms they are prescribed for. This can be an extreme health risk for those who are on long-term or permanent medications. It is best to ask your physician if apple cider vinegar can affect your medications before taking these tablets.
