Betaine comes from a normal diet but is also synthesized in the body where it contributes to metabolism in various ways, including as an anti-inflammatory agent. Levels of betaine (glycine betaine or trimethylglycine) in the blood plasma of patients with schizophrenia has previously been found to be low, which suggested it is a possible therapeutic target.
I read about this. It works similiar to choline.
Maybe I should start drinking beet juice again. (A source of betaine.)
