New Research Suggests…
Vitamin B-6 May Provide Cancer Protection
Increased Vitamin B-6 consumption could lower the risk of several types of cancer by fostering DNA repair, and it may be particularly important for individuals who smoke, US researchers suggest.
The researchers gave 12 people, divided evenly between smokers and non-smokers, a diet depleted in vitamin B-6. They discovered that after 28 days, all participants had lower levels of the vitamin in their blood and higher numbers of DNA strand breaks. Smokers who began the study with low vitamin B-6 levels had even lower levels of the vitamin at the one-month follow-up, and a greater number of DNA strand breaks.
For the next month the groups were given a diet that included 1.4mg of vitamin-B-6, which is around the recommended daily allowance (RDA). The groups then went through a third month consuming 2.2mg per day of vitamin B-6. In the fourth and final month of the study, participants were allowed to eat whatever they wished but were given more than SEVEN TIMES the RDA of vitamin B-6.
As the amount of vitamin B-6 in the diet increased, body levels of the vitamin went up and DNA strand breaks decreased, beginning as early as the first month of vitamin B-6 supplementation. After three months of consuming increasingly high levels of the vitamin, the status levels of the smokers became “acceptable” but never caught up with their non-smoking peers, said the researchers.
“Considering vitamin B-6’s role in DNA synthesis and repair, these results suggest that the current RDA for this critical vitamin is too low for even moderate smokers, and even could be too low for the population as a whole,” said Dr Shultz. He added, “The good news from the WSU study is that adding vitamin B-6 to the diet rapidly improved both smokers and non-smokers’ vitamin B-6 status and decreased the number of DNA strand breaks in both groups.”
The research is published in the Journal Experimental Biology.
Editors Comment: More evidence of why you need to take a comprehensive “multi” such as our MultiSmart™… and not your typical one-a-day that gives you minimal amounts of these important vitamins.
Also, let’s not forget that B-6 along with Folic Acid and B-12 converts homocysteine into harmless methionine. Homocysteine has recently been identified as a risk factor in heart disease.
