He Was Doing Everything Right. His Micronutrient Test Told a Different Story.
What one nutrition expert discovered about his own health—and why looking beneath the surface can sometimes change everything.
By Peak Health | The Journey to Peak Health
We all know the fundamentals of healthy living.
Eat nutritious foods. Exercise regularly. Get enough sleep. Manage stress. Take care of your body.
For many of us, these habits become part of our daily routine. We choose organic foods, avoid heavily processed ingredients, take supplements, and make conscious decisions about our health.
But what happens when you’re doing all the right things and still aren’t seeing the results you expect?
What if there’s something happening beneath the surface that your healthy lifestyle alone isn’t revealing?
That’s exactly the question that made Brian Dubyak’s recent experience with cellular micronutrient testing so interesting.
And his story offers an important lesson for anyone interested in longevity, preventive health, and extending their healthspan.
Meet Brian Dubyak: Someone Who Knows Nutrition
Brian isn’t someone who needs to be convinced of the importance of eating well.
As a nutrition expert, he has spent years learning about the relationship between food and health. He eats clean, prioritizes organic foods, exercises consistently, and makes intentional decisions about what he puts into his body.
Nutrition isn’t simply something Brian thinks about occasionally.
It’s part of how he lives.
Yet despite his efforts, there were two aspects of his health that continued to frustrate him.
His blood pressure remained higher than he wanted.
And his HDL cholesterol remained lower than he hoped.
He was already doing many of the things typically recommended to support cardiovascular health.
So why weren’t these numbers improving?
That’s when Brian decided to look a little deeper.
The Test That Revealed Some Surprises
Brian completed a Cellular Micronutrient Assay, a laboratory assessment designed to evaluate cellular responses associated with a range of vitamins, minerals, amino acids, and other nutrients.
The results were surprising.
Despite his carefully considered diet and healthy lifestyle, Brian’s report identified multiple nutrients in the laboratory’s insufficient or borderline insufficient categories.
Among the findings were:
Nutrient | Brian’s Result | Laboratory Classification |
Arginine | >140% | Insufficient |
Vitamin B3 | >140% | Insufficient |
Vitamin B2 | 130% | Insufficient |
Chromium | 124% | Insufficient |
Iodine | >140% | Insufficient |
Histidine | >140% | Insufficient |
Glutathione | 121% | Insufficient |
Vitamin B12 | 117% | Borderline |
Vitamin B1 | 111% | Borderline |
These figures reflect the laboratory’s assay-specific scoring system, not the percentage of a nutrient missing from Brian’s body. They are not equivalent to conventional blood measurements of nutrient concentrations.

For someone who pays so much attention to nutrition, the results raised some fascinating questions.
But two findings stood out above the others.
Arginine and vitamin B3.
And both were connected to health concerns Brian had been trying to address.
Surprise #1: Arginine and Blood Pressure
For some time, Brian had been experiencing consistently elevated blood pressure.
His readings were frequently around 130/90 mmHg.
He exercised regularly and followed a low-sodium diet, yet his blood pressure remained stubbornly elevated.
Then his micronutrient report revealed something unexpected.
Arginine was one of the nutrients flagged as insufficient.
Why is arginine important?
Arginine is an amino acid that plays several roles in the body, including supporting protein synthesis, immune function, and wound healing.
One of its particularly interesting functions involves the cardiovascular system.
Arginine is used by the body to produce nitric oxide, a molecule that helps blood vessels relax and supports normal blood flow.
Nitric oxide plays an important role in vascular function and blood-pressure regulation.
This relationship made the finding especially interesting to Brian.
He began supplementing with arginine and subsequently noticed that his blood pressure started to decrease.
For Brian, this was an encouraging development.
However, it’s important to distinguish his personal experience from a proven cause-and-effect relationship. His test did not establish that insufficient arginine caused his elevated blood pressure, and his improvement does not establish that supplementation was solely responsible.
What it did provide was another piece of information worth exploring.
And that information led Brian to ask questions he hadn’t previously considered.
Surprise #2: Vitamin B3 and HDL Cholesterol
Brian’s second surprise involved another cardiovascular health marker.
His HDL cholesterol.
HDL is commonly referred to as good cholesterol because HDL particles participate in transporting cholesterol from peripheral tissues toward the liver.
Brian had been trying to improve his HDL levels through diet and exercise.
But despite his efforts, his HDL remained lower than he wanted.
His micronutrient results identified vitamin B3 as insufficient.
What does vitamin B3 do?
Vitamin B3, also known as niacin, is essential for many metabolic processes.
It helps the body convert food into usable energy and contributes to normal cellular function.
Niacin also has a well-established relationship with lipid metabolism.
At prescription-level doses, certain forms of niacin can increase HDL cholesterol, although raising HDL with niacin has not consistently translated into better cardiovascular outcomes. High-dose niacin also carries risks and is not routinely recommended solely to raise HDL.
For Brian, discovering that vitamin B3 had been flagged on his report was another unexpected finding.
He had spent considerable time trying to improve his cholesterol through lifestyle choices.
Now he had additional information to discuss with a healthcare professional.
Importantly, his report did not establish that a B3 deficiency caused his low HDL, and we do not yet have evidence that addressing the finding changed his cholesterol levels.
Nevertheless, it was another reason to look more closely at his individual nutritional picture.
The Bigger Surprise: There Was More to Explore
Arginine and vitamin B3 attracted Brian’s attention because they related to health concerns he was already monitoring.
But his report contained other interesting findings.
Several B vitamins were flagged.
Certain minerals were identified as insufficient according to the laboratory’s scoring system.
The report also highlighted glutathione, an antioxidant involved in protecting cells from oxidative damage.
Some amino acids were classified as borderline insufficient.
And the accompanying Antioxidant Protection Assay provided additional information about cellular responses to various antioxidant compounds.
On page five of Brian’s report, for example, the laboratory assigned a Redox Score of 82, which it uses to describe cellular responses associated with oxidative stress. The report also identified several compounds that demonstrated protective responses in its assay.
These findings aren’t diagnoses, and the clinical usefulness of specialized cellular-response assays should be considered alongside established nutritional assessments and conventional laboratory testing.
But for Brian, they created an opportunity to have a more detailed conversation about his nutrition.
And that’s an important distinction.
The goal of testing isn’t to collect a list of things that might be wrong.
It’s to gather information that may help guide more thoughtful decisions.
What Can We Learn From Brian’s Experience?
Perhaps the most important lesson from Brian’s story isn’t about arginine, vitamin B3, or any single nutrient.
It’s about assumptions.
Most of us make assumptions about our health.
We assume that because we eat well, our nutrition must be adequate.
We assume that because we take supplements, we’re getting what we need.
We assume that if we’re exercising regularly and maintaining a healthy lifestyle, we’ve addressed every important factor.
And while those habits are incredibly valuable, they don’t always tell us everything.
Healthy habits provide the foundation. Individualized information can help us understand where to focus next.
That doesn’t mean everyone needs extensive testing or additional supplements.
It means that when questions remain unanswered, looking more closely may sometimes be worthwhile.
Why This Matters for Healthspan
At Peak Health, we often talk about the difference between lifespan and healthspan.
Lifespan is how long we live.
Healthspan is how long we remain healthy, active, independent, and able to enjoy the things that matter most to us.
Nutrition plays an important role in that journey.
Vitamins, minerals, amino acids, and other nutrients participate in essential processes throughout the body.
They contribute to energy metabolism, muscle function, immune health, nervous-system function, and many other processes associated with maintaining health as we age.
Understanding our nutritional needs can help us make more informed choices about diet and supplementation.
That’s why Peak Health continues exploring new tools that may help us better understand individual health.
From advanced blood panels and genetic insights to metabolic assessments and micronutrient testing, our goal is to bring together information that helps patients make informed decisions.
Not every test is necessary for every person.
And no single test provides a complete picture.
But used thoughtfully, testing can become part of a broader, personalized approach to health.
Because the goal isn’t simply to live longer.
It’s to live better for longer.
Curious About Your Own Micronutrient Picture?
Brian’s experience raises a question worth considering.
If someone who understands nutrition as well as Brian can encounter unexpected findings, what might the rest of us learn by looking more closely?
At Peak Health, we now offer Cellular Micronutrient Testing as another option for people interested in exploring their nutritional health.
The assessment examines cellular responses associated with 55 nutrients across four categories.
Your results can then be reviewed alongside your health history, dietary patterns, symptoms, and personal goals.
The objective isn’t to encourage unnecessary supplementation.
It’s to help you and your healthcare team determine whether further evaluation or changes to your nutritional approach may be appropriate.
Stop guessing. Start understanding.
