It depends on the patient's body weight, baseline markers, and periodic health checks. This can be determined after an evaluation with your doctor or nutritionist: • High-risk individuals: 3 to 12 times a year (depending on their condition); • Low-risk individuals or those in good health: 2 to 3 times a year. If you think ProLon® is right for you, contact your doctor or nutritionist, who will be able to advise you and authorize your use of ProLon®; or contact our staff, who will answer all your questions.
