NEW YORK (Reuters Health) – Men with earlier-stage prostate cancer may have better survival odds if they get a little more than the recommended amount of vitamin B6 everyday, a new study suggests.
The findings, reported in the American Journal of Clinical Nutrition, do not prove that vitamin B6 improves prostate cancer survival. But they do point to an association between survival and amounts of the vitamin that are readily attainable through a balanced diet.
Researchers found that among 525 Swedish men with prostate cancer, the one-quarter with the highest B6 intakes were 29 percent less likely than those with the lowest intakes to die of the disease during the study period.
Men in the former group averaged 2.2 to 2.9 milligrams of vitamin B6 per day, while those in the latter group got 1.3 to 1.9 milligrams daily. The recommended vitamin B6 intake for men age 50 and younger is 1.3 mg per day, while older men are encouraged to get 1.7 mg.
The protective effect of B6 appeared confined to men whose tumors had not yet spread beyond the prostate at the time of diagnosis.
