Dr Makis put me on 20,000IU when I had existing tumors then cut me back to 10,000IU after the tumors were removed. Here is the results. Remember to take with k2. He also has me on Curcumin 1000mg split in 2 doses. If you are in doubt, go to labcorp online and order a vitamin test, this is what i did. They will test you at a facility near you. My testing is done at Walgreens up the street my my house. Be your on advocate. Hugs

PS keep in mind I am not taking any medications that would interfere with VitaminD3 or curcumin, this maybe why she wants you off these supplements. Hugs

It's not uncommon for oncologists to adjust supplements during breast cancer treatment. Many supplements can interact with breast cancer medications in ways that may reduce their effectiveness.

Here's what's known about the supplements mentioned:

- Vitamin D3 — While vitamin D is important for bone health, levels need to be carefully monitored. Too much can cause side effects, and it can interact with certain medications
- Curcumin (turmeric) — Research suggests curcumin may interfere with enzymes that process some breast cancer treatments, potentially lowering their effectiveness in the bloodstream
- Calcium — Often paired with vitamin D, so stopping one may mean stopping the other A MyBCTeam member shared a similar experience, noting the importance of taking control of what you can and working closely with your care team on nutrition and lifestyle decisions.

It's great that you have an appointment coming up next month — writing down all your questions beforehand can help make the most of that conversation. Your oncologist can explain exactly why these were stopped and what alternatives, if any, might be appropriate for you.

My Oncologist stopped me from using curcumin for two reasons:
1. Curcumin can act as an inhibitor of certain liver enzymes,which are responsible for breaking down letrozole. Taking them together might cause letrozole to build up in your system, potentially increasing side effects.
2. Clinical trials haven't definitely proven its safety or efficacy when used on humans in conjunction with an Aromatase inhibitor.
All the best.
