Your body puts B-6 to use in activating nearly 120 enzymes and 19 of your body’s 20 amino acids. And all of that contributes to DNA repair, healthy immune, hormone, and cognitive functions, as well as prevention of heart disease, depression, kidney stones, and some cancers.?
B-6 has been shown to modify the way the prostate responds to testosterone.??Therefore?B complex?may have a preventive effect on the development and progression of prostate cancer.
To investigate this link, a team from the Harvard School of Public Health looked at dietary habits of 525 men with prostate cancer. Survival over a period of 20 years was compared to the intake of four B vitamins: folate, riboflavin, B-6, and B-12.
Results: Men with highest B-6 intake were significantly more likely to survive the two decades compared to men with the lowest intake of the vitamin. None of the other nutrients were linked to longer survival time.
Most importantly, men with the best survival records were those who had localized-stage prostate cancer at the outset of the study and also had the highest B-6 intake. In other words, high levels of the vitamin were most effective when the cancer was newly diagnosed and had not yet spread beyond the prostate.
Men who had the highest intake averaged 2.2 to 2.9 mg of B- 6 daily–about twice the recommended intake.?
Bananas and chicken breast have particularly high levels of vitamin B6. Red meat, fish, beans, fruits, vegetables, and leafy greens are also good sources.?
Daily recommends 100 mg of B-6 daily, along with other B vitamins, of course, and magnesium.
The Journal of American Medical Association (JAMA) did a review study of B6. Nine examined B6 intake, and four examined blood levels of PLP, the active form of B6. All the studies compared B6 status to cases of colorectal cancer.
Some of the studies include:
A Harvard Medical School study showed that subjects with the highest B6 levels had a much lower risk of colorectal cancer compared to subjects with the lowest levels
Tufts University research found that even a modest deficiency of key components in the B complex (including B6) increased colorectal cancer risk
In a large study from Scotland’s University of Edinburgh, high levels of B6 intake reduced colorectal cancer risk by more than 20 percent
Another Harvard trial found colorectal cancer risk significantly reduced among subjects who had the highest dietary intake of folate and B6
Dr. Tucker’s comment: Higher B6 intake and blood PLP levels were linked to lower colorectal cancer risk–and the higher the PLP levels, the stronger the link. Twelve years ago, John M. Ellis, M.D., put B6 on the map with a groundbreaking book titled “Vitamin B6 Therapy: Nature’s Versatile Healer.” In it, Dr. Ellis explains that PLP is a coenzyme that activates many crucial enzyme systems. In fact, nearly 120 enzymes need B6 to function properly, and 19 out of your body’s 20 amino acids require B6.
That’s why it’s no surprise that B-6 also plays a key role in many other health issues, including immune function, hormone function, and cognitive function, as well as the prevention of heart disease, depression, kidney stones, breast cancer, and prostate cancer.
The two best dietary sources of B6 are bananas and chicken breast meat. Fish, red meat, beans, and a wide variety of other plant foods also contain B6.
If you are afraid you are not getting proper amounts of B6 in your diet, I recommend Cortico-B5,B6 (100mg); Fem Essentials (40mg); and any of the UltraMeal products (25mg)
