The Role of Vitamin D in Cancer Supportive Care
Helping you understand “how vitamin D can help you stay steadier during treatment”
Vitamin D is not just the “bone vitamin” — in the supportive phase of cancer care, it plays an increasingly important role.
Many patients experience fatigue, bone pain, reduced immunity, and low mood during or after treatment,
and vitamin D deficiency is often the hidden culprit behind these symptoms.
Supplementing vitamin D can help alleviate side effects, improve tolerance, and support overall recovery, making the treatment journey smoother.
Prevalence of vitamin D deficiency in cancer patients
Cancer patients are prone to vitamin D deficiency due to several factors:
- Prolonged indoor treatment and limited sun exposure, greatly reducing skin synthesis of vitamin D
- Chemotherapy or radiotherapy damaging intestinal mucosa, impairing vitamin D absorption
- Temporary kidney dysfunction, hindering conversion to the active form (1,25-dihydroxyvitamin D)
- Chronic inflammation caused by the tumour or treatment accelerating vitamin D consumption
- Dietary insufficiency: Hong Kong dietary habits include relatively few vitamin D-rich foods (salmon, egg yolks, fortified milk)
Specific impacts of vitamin D deficiency
Vitamin D deficiency exacerbates the burden of cancer treatment, with common manifestations including:
- Bone pain and muscle soreness: accelerated bone density loss, fragile bones, frequent night-time leg cramps or widespread aches
- Increased fatigue: slowed energy metabolism, making patients more prone to “power outages”
- Reduced immunity: decreased T-cell and NK-cell activity, higher infection risk
- Low mood: vitamin D participates in serotonin synthesis; deficiency increases risk of anxiety or depression
- Lower treatment tolerance: bone pain and fatigue often lead to dose reduction or treatment interruption
How vitamin D supports cancer patients in the supportive phase
Vitamin D supplementation provides multi-level support, helping treatment proceed more smoothly:
- Promotes calcium absorption and bone maintenance, reducing bone pain and bone density loss
- Improves mitochondrial function and energy metabolism, alleviating fatigue
- Regulates the immune system, enhancing T-cell and NK-cell activity to better combat infections
- Lowers chronic inflammatory cytokines, easing systemic inflammation
- Supports nerve and mood stability, improving brain fog and low mood
Advantages of IMI Vitamin D injection therapy in supportive care
Oral vitamin D has limited absorption, especially in patients with intestinal damage.
IMI Vitamin D injection therapy (intramuscular) raises blood levels quickly and safely, with key advantages:
- Near-100% absorption, bypassing intestinal absorption barriers
- Long-lasting effect: a single injection maintains stable levels for months
- Precise dose control: physician adjusts based on blood test results to avoid excess
- Ideal for patients during treatment or with poor gut function
Important considerations for IMI Vitamin D injection therapy
IMI Vitamin D injection therapy is a professional medical procedure — **it must never be self-purchased or used at home**. It can only be administered in a medical facility after evaluation by a qualified physician.
The physician will individually adjust dosage and frequency based on your latest vitamin D levels, calcium/phosphorus metabolism, and kidney function.
Full monitoring is conducted before and after each session to ensure complete safety and comfort.
Every detail is guided by the principle of “making you feel as comfortable as possible” and coordinated with your primary treatment plan.
Summary
Vitamin D in the cancer supportive phase is not an optional supplement —
it is a key support for “stabilizing bones, energy, and immunity”.
When vitamin D levels return to normal, bone pain decreases, fatigue eases, tolerance improves,
allowing you to complete your treatment course with more strength and a faster return to normal quality of life.
If you are currently troubled by bone pain, fatigue, or reduced immunity during or after treatment,
