Addressing Low Acid Production
Heartburn is typically a sign of having too little stomach acid. To encourage your body to make sufficient amounts of hydrochloric acid (stomach acid), you'll also want to make sure you're consuming enough of the raw material on a regular basis.

High-quality sea salt (unprocessed salt), such as Himalayan salt, will not only provide you with the chloride your body needs to make hydrochloric acid, it also contains over 80 trace minerals your body needs to perform optimally, biochemically. Sauerkraut or cabbage juice is also a strong—if not the strongest—stimulant for your body to produce stomach acid. Having a few teaspoons of cabbage juice before eating, or better yet, fermented cabbage juice from sauerkraut, will do wonders to improve your digestion.
