Vitamin B6 Intake, Blood Levels Reduce Risk for CRC

Reviewing studies of both vitamin B6 intake and blood levels, Swedish scientists found a 20 percent reduction in colorectal cancer risk between people with most B6 and those with the least.

The research team found 9 prospective studies of B6 intake and 4 of B6 blood levels.  Pooling them, they found a relative risk of colon, rectal, or colorectal cancer that was .80 — or a 20 percent reduction in risk — between highest and lowest categories of either intake or blood levels.

The Stockholm team, led by Susanna C. Larsson, PhD, concluded,

Vitamin B6 intake and blood PLP levels were inversely associated with the risk of colorectal cancer in this meta-analysis.

    These studies only looked at risk for getting colorectal cancer, not recurrence.

    So, the answer is that we don’t know from this study whether Vitamin B6 affects recurrence or not.

    Kate,

    Does this also apply for people who already had a colon resect with respect to tumor recurrence?
