Calcium
Minerals
A mineral best known for bone health that also has research links to lower colorectal cancer risk. Getting enough calcium — ideally from food — supports the gut lining and bone strength during treatment.
- Adequate calcium intake is associated with a modestly lower risk of colorectal cancer.
- Supports bone strength, which matters during some cancer treatments.
- Works together with vitamin D for absorption and cell regulation.
Aim for food sources first — dairy, fortified plant milks, leafy greens, tofu. Use a supplement only to fill a gap, paired with vitamin D.
Very high calcium (especially from supplements) has been linked in some studies to higher prostate cancer risk — don't over-supplement. Confirm your target dose with your care team.
