Great question for anyone managing follicular lymphoma (FL)! Vitamin D levels do matter with FL — research suggests that low vitamin D before starting treatment may be linked to earlier relapse or poorer outcomes.

Great question for anyone managing follicular lymphoma (FL)! Vitamin D levels do matter with FL — research suggests that low vitamin D before starting treatment may be linked to earlier relapse or poorer outcomes.

That said, 5,000 IU of D3 daily is on the higher end, and whether it's "too much" really depends on your current blood levels and your oncologist's guidance. Taking too much vitamin D can cause some unwanted side effects, including:

- Nausea and vomiting
- Muscle weakness
- Confusion
- Dehydration
- Kidney stones

Vitamin D can also interact with certain medications, which is especially important to keep in mind during lymphoma treatment.

The best step is to ask your oncologist to check your vitamin D blood levels (a simple test) so you can dial in the right dose for *your* specific situation — not too little, not too much. It's a conversation worth having!
