Review · Advertisement by mybody x
“The whole thing read like a study of my own body, so it was super interesting.”
Tim R. took the Longevity DNA test and talked about it in a video. All quotes on this page are taken verbatim from that video. Tim gave written consent to its publication.
Tim’s full-length video, around 3 minutes. In the video, Tim mentions a money-back guarantee. mybody x does not offer such a guarantee; the statutory 14-day right of withdrawal applies. What Tim says about how he feels is a personal experience; no effect of the test can be inferred from it.
Part One · The Occasion
Why did Tim take a DNA test?
Out of curiosity. He had spent months researching longevity, or healthy aging, and wanted to tailor his diet to his genetic predisposition.
“I’ve been interested in longevity and healthy aging for several months now, simply because I found the topic really interesting. A few interesting Netflix documentaries came out, and I watched them all.”
Longevity means living a long life; it usually refers to aging healthily. A DNA test does not predict how old someone will live to be. It describes predispositions associated with diet, exercise, and skin.
“So I looked at the longevity test and found it really interesting at first […]”
"Adapting your diet to your genetic predisposition sounded really exciting to me. I’d never tried anything like it before, but I was intrigued, so I went ahead and ordered the test."
“And I was especially impressed by the depth of detail in the entire analysis.”
Part Two · The Rehearsal
How does the sample collection for the Longevity DNA test work?
With just a little saliva, at home, and without an appointment. The results arrive 15 to 25 business days after the sample is received.
“When the test kit arrived, collecting the sample was super simple and straightforward. I just took a saliva sample and sent in the results […]”
- Order. The test kit arrives by mail; shipping takes 2–4 business days.
- Collect your sample. Spit into a tube through a small funnel. No cheek swab, no needle.
- Send it back. Send the tube back to the lab.
- View your results. Your results will be available in the app and as a PDF in the customer portal 15 to 25 business days after the sample arrives.
Your DNA doesn’t change. That’s why one test is enough for a lifetime.
Part three · The result
What does the Longevity DNA test result say?
Four topics from a saliva sample: weight loss, nutrition, fitness, and skin, plus an evaluation of over 1,000 foods.
“And I was already quite surprised by how extensive the whole thing was.”
The Longevity DNA Test combines everything otherwise available individually at mybody x in one test. More than 170 genetic variations are analyzed and explained in reports.
“A huge number of foods were analyzed to see how well or poorly I tolerate them. For example, I now know that I tend to tolerate carbohydrates less well and should focus more on protein and fat. I also received more information about the micronutrients I should pay particular attention to.”
What does it mean to “tolerate carbohydrates less well”?
This refers to a predisposition, not an intolerance.
The report describes predispositions related to nutrition and metabolism and explains which foods may suit them. A DNA test cannot show whether you tolerate a food; that requires medical assessment.
Micronutrients are vitamins and minerals that the body needs in small amounts. The report notes which ones you may want to pay particular attention to based on your predispositions. It does not measure your current nutrient levels.
Is the DNA test worth its price?
Everyone decides that for themselves. Tim says this in the video:
“And I have to say, for an investment like this, it’s definitely worth it to the point where I’d say the price is completely justified, because it was truly incredible.”
For context: A DNA test is done once, and a result obtained once remains usable permanently.
“What I found absolutely impressive, though, was the MyFoodBook. I received a personalized plan with recipes tailored perfectly to my diet.”
Tim also purchased MY FOODBOOK. It is a standalone product from mybody x with recipes tailored to your personal results; it is included with the INFINITY DNA test.

Part Four · Implementation
What did Tim do with his DNA test?
He picked out what was new to him and incorporated it into his diet.
“I’ve changed quite a bit when it comes to nutrition […]”
“Of course, I picked out the parts that I found super, super interesting. You’d already incorporated a lot of it somehow, and a lot of it you didn’t know yet. I just changed up my diet based on what I didn’t know yet.”
That’s what the test is for. It doesn’t prescribe anything; it offers perspective. Some things confirm what you’re already doing, while others are new and worth trying.
“I can recommend it. I’ve already recommended it to many people privately, too.”
What the test can't do
Does a DNA test replace a medical examination?
No. It does not make diagnoses or say anything about illnesses.
The Longevity DNA test describes, in clear language, predispositions you were born with. It does not measure blood values or tell you how you are doing today. A predisposition does not determine your future.
What you make of the results and how you feel about them depend on more than just a test. The Longevity DNA test does not promise a change in how you feel or a longer life.
The DNA test describes the predispositions you have. A blood test shows your current values, and a gut test provides information about your gut flora. If you have any symptoms, your doctor is the first person to contact.
We provide the data. What you do with it is up to you.
