Summary

This study looked at whether taking beetroot juice (which is rich in nitrates) together with vitamin C could lower blood pressure and improve blood vessel health in overweight adults aged 50-75. Fifteen participants took either the combination, beetroot juice alone, or a placebo. The goal was to see if the combo works better than beetroot alone for people at higher risk of heart disease.
