Background and aim: Providing a healthy lifestyle is the first stage of controlling hypertension, which is an important public health problem. However, lifestyle modification targets can only be achieved among limited patients. As a result, expected benefits from those modifications remain limited. In this research, we aimed to verify the additional gains from salt restriction counseling on blood pressure control among primary hypertensive patients already receiving pharmacotherapy.Materials and methods: Primary hypertension patients under a stable medical treatment were randomly assigned to a salt restriction group and a control group. All participants completed a questionnaire of demographic data, medical history, and diet. Twenty-four-hours ambulatory blood pressure measurements were recorded at the beginning and at the end of 3 months. Personalized education and counseling were performed only to the salt restriction group. Patients were followed up with phone calls. Effects of salt restriction were evaluated with sodium excretion on 24-hour urine.Results: Total 172 patients enrolled in the study; 86 patients were in salt restriction group and 86 patients were in control group. The patients’ 71,5% (123) were women, 28,5% (49) were men. The mean age of participants was 56,8±5,9 years. Urinary sodium excretion increased 1.8±5.2 g/day in the control group (Z=3,120; p=0,002) but decreased 1,0±4,9 g/day in the study group (Z=1,983; p=0,047). Ambulatory systolic and diastolic blood pressures increased 3.2±9.3/2.3±6.9 mm Hg in the control group (Z=3,165; p=0,002/Z=2,956; p=0,003), whereas they decreased 6.1±9.4/4.7±7.8 mm Hg in the salt restriction group (Z=5,137; p
