この研究の注釈：
In obese subjects given supplementation of betaine at 6g daily for 12 weeks was able to decrease homocysteine (9%) relative to placebo but the decrease in total cholesterol and LDL seen in placebo was not present in betaine intervention; there was no influence on body weight. There was no influence on plasma nor RBC folate concentrations.
