A healthy range for total cholesterol levels is typically considered to be below 200 mg/dL. Levels between 200 mg/dL and 239 mg/dL are regarded as borderline high, while levels of 240 mg/dL and above are considered high and may increase the risk of heart disease. It’s essential for individuals to monitor their cholesterol levels regularly, as maintaining a healthy cholesterol balance is crucial for reducing the risk of cardiovascular issues and promoting overall heart health through diet and lifestyle changes.
