The acidic environment in the stomach is vital for digesting food. Hydrochloric acid (or HCL) maintains a pH in the stomach of approximately 2.0, which is optimal for digestion and also protects the stomach from potentially harmful microorganisms. Hydrochloric acid in gastric juice secretions activates the enzyme pepsin to initiate the breakdown of proteins.*

Deficiency of Gastric Acid
Stomach acid is a powerful digestive aid. After a high-protein meal, the pH in a healthy stomach may drop to as low as 1 or 2. However, buffers quickly raise the pH back to 3 or 4.

With age, stomach acid secretion tends to decrease, resulting in low stomach acid, poor digestion, and mineral deficiency. But HCL supplements help make minerals and nutrients more absorbable. Achieving the correct pH is a key to maintaining proper digestive function and overall health.*

Most people use Betaine HCL, but if you develop sensitivity to it, consider HCL 5% drops. In very rare cases people have too much acid; in that case you will feel a burning sensation or heartburn when taking HCL with your food.*


Water, hydrochloric acid

Suggested Use
Put up to 10 drops in food per use or up to 45 drops total per day in food.

Note: Hydrochloric Acid can be taken with any type of food. It can be taken with water or juice.

Warning: Avoid contact with eyes, skin and clothes. Do not put drops directly in mouth, it can dissolve teeth. For heartburn take water and milk, do not take baking soda. If heartburn persists seek the care of a qualified professional.

Store at room temperature. Keep out of reach of children.


Frequently Asked Questions
Q: How many drops are equivalent to one capsule of Betaine HCL?
A: While both 5% HCL drops and Betaine HCL capsules serve the same purpose (to raise the acid level in the stomach), they are chemically different products. Therefore, there is no true equivalency.

Q: Can I put the drops directly in my mouth?
A: Putting the drops directly into the mouth is not recommended. Even at 5% potency, HCL is still strong enough to ware away the teeth at full strength. Taking the drops mixed in food or a beverage is suggested.

Q: How many drops do I take with each meal?
A: The suggested use is up to 10 drops mixed in food at each meal, or up to 45 drops total per day. Alternatively, you can mix the drops in a beverage instead of mixing them with food.

Q: How many drops are in one bottle.
A: There are approximately 750 drops in each 1 fl oz bottle.
