Preventative uses

Additionally, several preliminary studies on both rats and humans have shown betaine may protect against liver disease, particularly the buildup of fatty deposits in the liver caused by alcohol abuse, protein deficiency, or diabetes, among other causes. The nutrient also helps individuals with hypochlorhydria, a condition causing abnormally low levels of stomach acid, by increasing stomach acidity.
