Last year I signed up for Arivale’s beta program. They’re attempting to quantify participants’ state of health through DNA sequencing, gut microbiome sequencing, FitBit tracking, interviews, and periodic saliva and blood tests. I’m enjoying the experience so far, and very much looking forward to analyzing my own whole genome (just as soon as my BAM is finally available…)

So far I’ve had two blood tests: one last November, and one a last month. There’s not enough data to establish a real trend yet (particularly since they switched lab service companies between samples). But it’s still fun to see extensive blood work results mapped out on a nice easy-to-read chart.

This month my personal coach pointed out that my homocysteine and overall cholesterol levels look a little high. Previously my homocysteine level appeared quite low, which might be due to a bunch of factors.

Changing labs between samples means that direct comparisons are less meaningful. My coach wanted to know if my diet or habits have changed significantly since the last draw. Six months is a long time to account for, but I really couldn’t think of a significant change on my part.

She recommended taking a B12 supplement to help offset the rise in homocysteine.

That’s when it hit me: there was a subtle shift in my diet since last winter. I may have been inadvertently supplementing my diet with B vitamins after all.

One of my shop mates sprung for a case of Red Bull last year. It had been sitting around the shop for a while, and after a few long nights slaving over a hot SEM power supply, I started drinking the stuff. And eventually bought a second case.

Red Bull is, of course, quite high in B6 and B12.

About halfway through the second case I was starting to have trouble sleeping and generally felt overcaffeinated, so I completely quit drinking the stuff.

Neither I nor my counselor (a nutritionist) are doctors, but the Mayo Clinic indicates there is some scientific basis for lowering homocysteine by increasing intake of B vitamins. The overall affect on cardiovascular health seems to be an open question leaning toward “probably not relevant”.

I’m still not sure whether the amount I got from a Red Bull or two every other day would account for the shift in levels, but it’s a fun theory. It’s the first time I’ve ever had the thought that soda might be good for me.

But don’t worry, I’m switching from Red Bull to a B12 supplement with significantly less sodium, sugar, and caffeine.
