Betaine, izina ry'ikinyabutabire ni trimethylglycine, ishingiro ry'ibinyabuzima riboneka mu mibiri y'inyamaswa n'ibimera. Rifite ubushobozi bwo gushonga cyane mu mazi n'imikorere yabyo, kandi rikwirakwira mu mazi vuba,gukururakwita ku mafi no kongera ubwiza bw'ibyambo byo kuroba.

Ubushakashatsi bwagaragaje kobetainebishobora kongera ubushake bwo kugaburira amafi neza, bikagabanya kuba maso, kandi bikongera amahirwe yo kuruma amafi.

Byongeye kandi, uburyo bwo gukoreshabetaineNabyo ni ikintu cy'ingenzi bigira ingaruka ku mikorere yabyo. Bishobora kongerwa ku cyambo cyangwa bikavangwa n'ibindi bintu bikurura amafi mu buryo butaziguye kugira ngo byongere ingaruka z'ibyambo by'amafi.
