Betaine hydrochloride is widely used as a dietary supplement to support digestive health. It aids in the production of stomach acid, which is essential for breaking down food and absorbing nutrients effectively. This makes it particularly beneficial for individuals with low stomach acid levels, a condition known as hypochlorhydria.

In addition to its digestive benefits, it is also utilized in the treatment of homocystinuria, a genetic disorder that affects the metabolism of the amino acid methionine. By helping to lower elevated levels of homocysteine in the blood, betaine hydrochloride can reduce the risk of cardiovascular complications associated with this condition.

Furthermore, it is sometimes included in formulations for sports nutrition and muscle recovery, as it may help improve exercise performance and reduce muscle fatigue. Its ability to support liver function and detoxification processes also makes it a valuable component in various health and wellness products.
