The recommended healthy triglyceride levels generally do not vary significantly by age. A triglyceride level below 150 mg/dL is generally considered desirable for adults of all ages. However, it's important to note that individual circumstances, such as existing health conditions and overall lipid profile, may influence target triglyceride levels. Consulting with a healthcare professional is recommended to determine the most appropriate triglyceride level for you based on your specific age, health status, and other relevant factors.
