They are huge, aren't they!! But then my CP meds are tiny- and I always have to double check to make sure they are in the pile when I dump the day's supplements into the cup!

My PCP told me that vit D deficiency is a bigger problem than it used to be because our lives are lived more and more indoors. We go from home to work and back to home maybe in our cars for a while but not even UV rays get through most car windows any more and that is where vitamin D comes from. He was especially concerned because I live in Indiana now and in winter we can go days without sun. Vit D can be measured on a simple blood test.

Our PCP said that it is not uncommon for us adults as we age to become more deficient in Vitamin D. Work with your PCP to find the right supplement for you- and always run anything past your oncology team as well! Hugs!

Vitamin D deficiency is worth paying attention to with breast cancer Show Full Answer

It's a really common concern among those with breast cancer! Many MyBCTeam members have shared questions and experiences around vitamin D levels — one member asked "Has anyone had issues with vitamin D?" while another mentioned taking a vitamin D booster.

Vitamin D deficiency is worth paying attention to with breast cancer because research suggests that low levels may be linked to a higher risk of developing breast cancer and poorer survival outcomes.

Some key findings include:

- Breast cancer patients with high vitamin D levels may be twice as likely to survive the disease compared to those with low levels
- Patients with sufficient vitamin D levels have shown significantly better survival outcomes than those who are deficient
- Low vitamin D may affect the body's ability to control normal breast tissue cell growth The good news is that checking your levels is simple — just a blood test at a regular check-up. If deficiency is found, a doctor may recommend supplements.

However, it's important not to over-supplement, as too much vitamin D can cause:

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

Always check with your health care provider before starting any supplement routine, as vitamin D can also interact with certain medications.

vitamin D3 should be taken with K2. It comes together in one pill and they aren’t that big.
