Other Recommendations and Considerations:
It's important to note that other organizations may provide slightly different recommendations. For example, some sources suggest higher amounts, particularly for adults, ranging from 600-800 IU to even 1500-2000 IU daily. These variations often depend on individual factors such as health status, sun exposure, and dietary habits. Always consult with your doctor to determine the appropriate dosage for your specific needs. Excessive intake of Vitamin D can lead to health risks.
