When you're going through cancer treatment, it's natural to look for anything that might help your body to recover. Vitamin D3 often comes up in those conversations. But how much does it actually matter during cancer care? Vitamin D is an important nutrient. Your body needs it for healthy bones, muscles, nerves, and normal immune function. Most of it is made when your skin is exposed to sunlight, while smaller amounts come from food and supplements. For someone with cancer, though, taking vitamin D3 is not as simple as taking a supplement and expecting it to improve the cancer itself.
Why do you need vitamin D
There is a deficiency of Vitamin D among those who suffer from cancer. This may be a lack of outdoor play time, changing food/drink habits, restricted food/excessive water, or other health concerns. Vitamin D deficiency may impact bone and muscle function. This might be relevant in patients who are already frail, inactive, or receiving therapies that might affect bone. Your doctor may suggest a blood test if he or she suspects your blood level of vitamin D may be too low.
Will vitamin D3 cure cancer?
This is where it's important to differentiate research from proven treatment. Research into the role of vitamin D and cancer has been ongoing for many years regarding possible associations with the risk of developing certain cancers or with outcomes of cancer diagnosis. Several studies have identified associations, but it doesn't necessarily mean that vitamin D3 can cure cancer. Vitamin D3 is not a substitute for chemotherapy, radiotherapy, surgery, or other recommended therapies for cancer treatment from your oncology team
D3 supplement for a cancer patient?
Not all supplements are required for everyone. Other than that, if you have a low vitamin D level, have controlled sunlight exposure, and still are not getting enough from food, vitamin D supplements may not offer significant benefit. Your doctor can suggest vitamin D if it is found that you are deficient through a blood test and will discuss a dosage with you. You should also mention any supplements used to your oncologist. Natural does not equal not harmful; an overdose of vitamin D can be harmful, such as excessive intake of high doses.
Vitamin D & bones?
Bone health may be a critical issue during and following cancer therapy. Lower physical activity can worsen the problem, while some treatments can reduce bone density and contribute to thinning bones. Vitamin D supports healthy bones. Your treatment team may also consider vitamin D, calcium, weight-bearing exercise, and bone density tests based on your individual risk.
Vitamin D3 plays an important role in helping with normal health, but it is not a cancer therapy. Inquire with your doctor about getting your vitamin D levels checked and whether a vitamin D supplement is right for you. The optimal dose is based on the individual's health status and not just the fact that they have cancer. Your oncology team will be able to help you determine what is better as per your treatment plan.
