There are two main types of vitamin D: D2 and D3. Vitamin D3 is generally considered more beneficial since it's the form naturally produced by your body during sun exposure and found in foods like oily fish. The active form used by your body is called calcitriol.

Before starting any vitamin D supplementation, it's crucial to discuss this with your oncologist. They can test your current vitamin D levels and recommend the appropriate type and dosage specifically for your situation. While vitamin D deficiency may impact lymphoma outcomes, taking too much can be dangerous. Excessive vitamin D can cause:
• Nausea and vomiting
• Muscle weakness
• Confusion
• Pain
• Dehydration
• Kidney stones

Your oncologist is best positioned to monitor your vitamin D needs as part of your overall cancer care plan.
