A study out of Medical University of Tehran presents data that suggests Vitamin D may help with asthma if taken along with normal asthma medication. 130 children and adults with mild-to-moderate asthma involved in the study were all given asthma medication in the form of a dry powder inhaler. But half of the individuals were also given large doses of vitamin D as a supplement for six months prior to the end of the study via intravenous delivery (100,000 units at the start of the study) and oral delivery (50,000 units weekly). The result showed that among the group that received vitamin D, lung function improved slightly. The results are by no means conclusive; however, scientists in the study say it may help a lot of asthma sufferers if research continues.

The headline above is good news for those of us who want to proactively protect our health and extend our lives. I remain pretty cynical about the vast majority of supplements that claim life-extension benefits, but this compound is one of the rare exceptions. Before describing this important paper, published by in the Oxford journal Human Molecular Genetics, let me explain a bit about oxaloacetate, which John Mauldin and I both take several times a day.

Have you known someone who seemingly lost their personality and mind, transforming into a husk with nothing left but an appetite that devastates the lives of those he or she once loved? Obviously, I’m talking about dementia and particularly Alzheimer’s disease (AD). If you’ve been reading my work, you know that the singular transformation of the 20th century was the near doubling of life spans in the West. Longer life spans are, of course, a good thing but there is a snake in the garden.

In other cancer-related work, Salk Institute researchers report in Cell that a synthetic form of vitamin D weakened the exterior of pancreatic cancer cells, thus making those cells more vulnerable to established cancer treatments. Typically, tumors have inflamed and dense exteriors as a result of the repair mechanism known as fibrosis. By weakening difficult to treat pancreatic cancer cells using a modified form of vitamin D, however, the hope is that this research will lead to new ways to attack other cancer types, such as lung, liver, and kidney.

New data presented at the European Society of Cardiology’s Acute Cardiovascular Care Association’s annual meeting suggests vitamin D deficiency could play a role in reduced brain function after a cardiac arrest. In a study of 53 patients at a hospital in Seoul, Korea, researchers found, for example, that 65% of those patients with low vitamin D had “poor neurological outcomes” six months later compared to just 23% of those patients with sufficient levels of vitamin D. Furthermore, among the low-vitamin D group, 29% had died at the six-month mark since cardiac arrest compared to none of the sufficient D group.

University of Georgia scientists have suggested a possible link between vitamin D deficiency and the development of seasonal affective disorder (SAD) in the journal Medical Hypotheses. The lag time between sunlight being converted into vitamin D by the body as well as the vitamin’s role in the synthesis of serotonin and dopamine in the brain could both play a role in how those with low D levels can develop symptoms of SAD. With further research, these findings could help establish a natural way to combat some forms of depression, as well as seasonal conditions like SAD.

Data recently presented at the World Stem Cell Summit in San Antonio, Texas, attempted to determine what, if any, role vitamin D played in helping to regulate the “body clock” effect of protein-coding activity. By isolating a specific set of genes and dosing them with vitamin D, the researchers found those genes behaved as they would in the body, with activity rising and falling on a set cycle. The cells did not respond as they did in vitamin D when placed in a separate solution. Though more work is needed to confirm this finding, it’s possible proper levels of vitamin D in the human body play a significant role in stabilizing and normalizing circadian rhythms.

As I mentioned last week, I’m multitasking while I finish a book on tech advances and their investing implications. Last Friday, you saw an excerpt of my book manuscript called “What’s Next, Part 1: The Rise of Biocomputing.” This week, we look deeper into the so-called tech singularity and investigate life-extension therapies.

Today I’d like to answer multiple questions sent to me regarding last week’s issue, in which I discussed the supplements that Mr. Mauldin and I are taking. By way of explanation, I didn’t include links to the actual products I discussed for the simple reason that I don’t want to give the impression that we’re recommending these products for financial reasons.

Excuse me if I ramble on today. Finishing the book project, on top of my writing and research routine, is putting a lot of pressure on me, so I’m sort of making it up as I go. Another consequence of a busy work schedule is that I occasionally skip a workout. I didn’t do that today, however, for several reasons.

I’ve been writing quite a bit about the ongoing reassessment of optimal nitrate levels in the diet. For many years, this reassessment happened behind the scenes as lonely researchers found holes in the status quo. Recently, interest into dietary nitrate seems to have reached a new intensity, due to the practice of consuming beet juice among elite athletes to boost physical endurance and strength.

Despite important scientific and philosophical progress in the brief Hellenic period of ancient Athens, it was the emergence of the Enlightenment in 1700s Europe that finally liberated science to improve the human lot. Human progress has accelerated exponentially since then, and with it, affluence and health. Unfortunately, few people seem to understand how fortunate we are to be alive today. So I’m always happy when someone puts things in perspective.

Just over a decade ago, gerontologists still considered aging an inevitable process largely outside the influence of medicine—but recently, many have begun to view aging as a “meta-disease” that can and should be treated.

It’s summer here in South Florida. Nearly every day, thunderstorms roll in around noon. Power surges and temporary outages caused by lightning are so frequent, I’ve stopped resetting the clock on the microwave.
