Individuals with schizophrenia who are treated with L-lysine could experience some relief from their symptoms, research has shown, indicating a lesser need for respite care from those who have the mental health condition.
For a study, published in BMC Medicine, patients received either L-lysine along with their normal medication or a placebo. Those who took the drug were seen to have a reduction in the severity of their symptoms.
Researcher Dr Caroline Wass said that the study is a starting place for more research to build on the effects of L-lysine in schizophrenia.
"It was an extremely low dose, and a small sized trial, which limited the conclusions we could draw. Nevertheless this study suggests that L-lysine may be of benefit to patients in alleviating some of the negative and cognitive effects of schizophrenia."
This follows findings that schizophrenia and bipolar disorder patients, who may utilise assisted living, are more likely to have bad physical health than those without a mental health disorder.
The research, published in journal BMC Psychiatry, found that two-thirds of patients with severe mental illnesses were overweight or obese.
