- DNA testing can teach you everything from your ethnic background and disease pre-disposition to food preferences and exercise habits.
- A DNA testing company called Vitagene approached me to take a DNA test for $100, so I swabbed the inside of my cheek and mailed the sample to their lab.
- I wasn't expecting anything significant, yet the results of my DNA test were a complete shock.
- A caveat: DNA testing is an imperfect science, and the FDA is only beginning to investigate the claims made by companies like Vitagene.
When I was approached to take a DNA test by a company called Vitagene, I was intrigued. I'd always wanted to know my ethnic breakdown (spoiler alert: mostly European). But what really fascinated me was the prospect of demystifying my genetic code — sort of.
Vitagene promised to dig into my one-of-a-kind DNA to determine my sensitivities and predisposed ailments. Plus, they'd give me a custom diet and exercise regimen and handpick the exact supplements I should be taking based not only on my genetics, but also on my family medical history, lifestyle habits, and health goals.
Of course, DNA testing is still an imperfect science, and there are currently no universal standards for accuracy. The FDA is only just starting to regulate the health claims made by DNA testing services. I never expected my test results to hold the same kind of weight as real diagnostic testing or be a substitute for real health professionals (and neither should you).
I swabbed the inside of my cheek, mailed the sample to their lab, and completed a quick questionnaire on their site. Easy peasy — and the whole thing costs a cool $100, cheaper than some other brands.
A month later, Vitagene emailed me a link to retrieve my password-protected results online. Some of the findings didn't surprise me: I have a high alcohol tolerance but I'm lactose intolerant. Carbs make me pack on the pounds, but fatty foods do not.
What did surprise me? Everything else.
Here are the most eye-opening things I learned from my DNA test.

1. I shouldn't rely on multivitamins
According to Dr. Julie Chen, an integrative medicine physician on Vitagene's advisory board, I should get all of my essential nutrients from the foods I eat. In other words, my diet should be my multivitamin. I should only take supplements to address my deficiencies (hence the word "supplements"). Excess vitamins can potentially be harmful — and the New York Times agrees.
My personal list of supplements is pretty short — and surprisingly bizarre. In addition to the usual suspects, like vitamin D and probiotics, Vitagene suggests I stock up on obscurities like chromium, glucosamine chondroitin complex, and — brace yourself — bromelain quercetin complex. Apparently, these pills will help regulate my blood sugar and protect me from joint pain and inflammation, respectively.
But do I need them? I'll let my (actual) doctor decide.
2. I may be predisposed to overindulging in food
The cat's out of the bag. I only exercise because I have to, and I keep my cupboards pretty bare because I have no self-control. The craziest part? I'm allegedly genetically predisposed to be this way!
In addition to my DNA being ravenous and sedentary, it is also stubborn about weight loss and muscle gain. Small portions that total 1,400 calories a day and extra reps at the gym are the only way my body weight will budge, thanks to my genes.
3. I should drop the yoga mat and pick up a barbell
Namaste? Not if I want to tone up, says Vitagene. I'm built to see more results from short, intense exercises, like sprinting and bench pressing, than from aerobic workouts like jogging, swimming, and yoga, which I love.
That said, I still need aerobic exercise to keep my heart healthy; I just have to work a lot harder. In short, I'm built to be the tortoise, not the hare.
