Does anybody here use apple cider vinegar (organic, unfiltered, raw) for low stomach acid, rather than Betaine HCl? Obviously it's a lot cheaper than the pills, and as long as it's well diluted, I don't see a downside. Unless, or course, it doesn't work! According to my searches, the 'formula' is 1 teaspoon in a glass of water immediately before eating. One site said to sip vinegar water throughout the day, but I don't see the benefit in that. Ideas?
