DID YOU KNOW that two less heralded B-vitamins have been shown to improve cognitive function?


A groundbreaking study by researchers in Aging Cell and funded by the National Institutes of Health has demonstrated for the first time that nicotinamide riboside, a special form of niacin, can penetrate the brain and significantly increase nicotinamide adenine dinucleotide (NAD+) levels. Nicotinamide riboside is a precursor to NAD+, a molecule essential for cellular repair and DNA damage restoration. This increase correlated with changes in biomarkers associated with neurodegenerative diseases like Alzheimer’s.


According to results of a study from Nutrients, optimal choline intake not only improves cognitive function, but also postpones cognitive decline during the aging process. The findings highlight the neuroprotective benefit of choline for middle-aged and elderly population, especially among females.

DID YOU KNOW that B-vitamins are important for more reasons than you think?


Higher intakes of folate, vitamin B6, and vitamin B12 were generally associated with a lower risk of CVD in the general population, according to a large study from Nutrition Reviews.


Dietary and supplemental folate are effective in stroke primary prevention, as reported in a study from Frontiers in Nutrition.


Researchers in The Journal of Nutrition found higher concentrations of urinary phthalate metabolites were associated with lower serum folate concentrations in children. Phthalate is a ubiquitous plasticizing chemical, showing how important getting enough folate is.


Another study from The Journal of Nutrition found that low vitamin B12 levels were linked to higher risk of male testosterone deficiency and infertility.


Showing how important it is to know your genetic predisposition to absorbing B-vitamins from food and supplements, a study from Nutrients purports that methylfolate, pyridoxal-5-phosphate (vit B6), and methylcobalamin (vit B12) supplementation tailored to genetic profiles effectively reduced homocysteine and LDL cholesterol levels in patients with specific MTHFR, MTR, and MTRR polymorphisms.

DID YOU KNOW that environmental toxins called phenols have an adverse impact on the heart's electrical properties, according to a federally-funded study in Environmental Health?


Toxic phenols may include preservatives in packaged foods, parabens in shampoos, and bisphenol A (BPA) in plastic dishware.


The heart is driven by electrical activity, so anything affecting its electrical properties can have a detrimental impact and possibly result in arrhythmias.


Researchers found higher exposure to BPA, BPF and BPA+F in women is associated with a longer PR interval, a delay in the time it takes for electrical signals to move from the atria at the top of the heart to the ventricles.


In men, researchers found higher exposure to triclocarban, an antimicrobial agent, led to longer QT intervals in the heart, meaning the heart's electrical system is taking too long to recharge, a situation that can contribute to heart rhythm dysfunction. 


Lest we think that toxin exposure is less of a priority, this study is a sobering reminder to sensibly lessen exposure without going overboard. For example, use stainless or glass instead of plastic whenever possible.
