Kupsinjika kosiyanasiyana kumakhudza kwambiri kadyedwe ndi kakulidwe ka nyama zam'madzi, kumachepetsa kuchuluka kwa moyo, ngakhale kufa. Kuphatikizika kwa betaine m'zakudya kungathandize kuchepetsa kudya kwa nyama zam'madzi chifukwa cha matenda kapena kupsinjika, kukhalabe ndi thanzi komanso kuchepetsa matenda ena kapena kupsinjika.

Betaine imatha kuthandiza nsomba kukana kuzizira kutsika pansi pa 10 ℃, ndipo ndi chakudya choyenera cha nsomba zina m'nyengo yozizira. Mbande za udzu wa carp zomwe zimanyamulidwa kwa mtunda wautali zidayikidwa m'mayiwe A ndi B okhala ndi zikhalidwe zomwezo motsatana. 0,3% betaine anawonjezeredwa ku udzu carp chakudya mu dziwe a, ndi betaine sanawonjezeredwe udzu carp chakudya mu dziwe B. Zotsatira zinasonyeza kuti udzu carp mbande mu dziwe a anali achangu m'madzi, kudya mwamsanga, ndipo sanafe; Mwachangu mu dziwe B ankadya pang'onopang'ono ndipo imfa inali 4.5%, kusonyeza kuti betaine ali ndi anti-stress effect.

Betaine ndi chinthu chomwe chimalepheretsa kupsinjika kwa osmotic. Itha kugwiritsidwa ntchito ngati chitetezo cha osmotic pama cell. Iwo akhoza kusintha kulolerana kwa tizilombo maselo chilala, chinyezi mkulu, mchere wambiri ndi hypertonic chilengedwe, kupewa selo madzi imfa ndi kulowa mchere, kusintha ntchito ya Na-K mpope wa selo nembanemba, kukhazikika enzyme ntchito ndi kwachilengedwenso macromolecular ntchito, kotero kuti kulamulira minofu ndi selo osmotic kuthamanga ndi ion bwino, Pitirizani ndi michere mayamwidwe amphamvu pamene osmotic kusintha, kumapangitsanso mayamwidwe a nsomba, ndi kuonjezera mayamwidwe a nsomba ndi mayamwidwe a nsomba, onjezerani kuchuluka kwa mawu.

Kuchuluka kwa mchere wachilengedwe m'madzi a m'nyanja ndikwambiri, zomwe sizimathandizira kukula ndi kukhala ndi moyo kwa nsomba. Kuyesera kwa carp kukuwonetsa kuti kuwonjezera 1.5% betaine / amino acid ku nyambo kumatha kuchepetsa madzi mu minofu ya nsomba zam'madzi ndikuchedwetsa kukalamba kwa nsomba zam'madzi. Pamene kuchuluka kwa mchere wachilengedwe m'madzi kumawonjezeka (monga madzi a m'nyanja), zimathandiza kusunga mphamvu ya electrolyte ndi osmotic ya nsomba zam'madzi am'madzi ndikupanga kusintha kuchokera ku nsomba zam'madzi kupita kumadzi a m'nyanja bwino. Betaine imathandizira zamoyo zam'madzi kukhalabe ndi mchere wochepa m'matupi awo, kumawonjezera madzi mosalekeza, kutenga nawo gawo pakuwongolera osmotic, ndikupangitsa nsomba zamadzi am'madzi kuti zigwirizane ndi kusintha kwamadzi am'nyanja.
