About this report
This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
What each result group means
Worth a conversation with your doctor
These came back with a higher genetic predisposition than most people. That is not a diagnosis — it means these are the ones worth raising at your next appointment.
Running above the typical range
Your genetics point to these sitting higher than average. Often useful to know, sometimes worth monitoring.
Running below the typical range
Your genetics point to these sitting lower than average. Same idea — context, not alarm.
Working in your favour
Good news. Your genetics look protective or better than average here.
In line with most people
Nothing unusual. These were tested and came back typical — worth having on record.
Your results at a glance
How to read this. A result being flagged does not mean you have a condition — it means your genetics put you above or below the average person for that trait. Of the 119 results here, 16 came back worth discussing with a clinician and 5 came back in your favour. Bring this document to your appointment.
What this package looks at
Amino Acids — Understanding the genetic predisposition for amino acid levels and needs is crucial for tailoring individual health and nutritional plans. This report delves into how genetic variations can influence the body's ability to absorb, produce, and use amino acids, potentially impacting overall
Blood Sugar Control — Blood sugar control is essential for maintaining energy levels, supporting metabolic health, and preventing long-term complications. Genetic predispositions can significantly influence how well your body regulates blood sugar. These genetic factors may affect insulin sensitivity, glucose
What you can actually do
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.

Your headline findings
Of the 119 results in this package, these 8 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.
Low Blood SugarMore likely
More likely to have low blood sugar based on 126,569 genetic variants we looked at
Your risk is greater than 99% of the population and lower than 1% of the population.
What this actually is
Other non-diabetic risk factors include age, drinking alcohol, certain medications, severe infections, problems with your adrenal or pituitary gland, liver, kidney, or pancreas.
Other diabetic risk factors include taking too much diabetes medication, not eating enough or skipping meals, increasing physical activity without adjusting diet or medications, and drinking alcohol.
If you have high genetic risk, you may lower overall risk by taking action on those factors that you can change.
What you can do
- Honey
Its osmotic effect also draws out excess fluid from the ulcer, speeding up the healing process.
From your Blood Sugar Control report
Food AllergiesMore likely
More likely to have food allergies based on 16,808 genetic variants we looked at
Your risk is greater than 95% of the population and lower than 5% of the population.
What this actually is
Key Takeaways: Up to 80% of differences in people's chances of having food allergies may be attributed to genetics.
Many allergies come and go through childhood, but common ones that linger into adulthood include nuts, seafood, milk, and eggs.
Reducing risk for allergies involves avoiding the various food triggers.
What you can do
- Avoid Food Triggers
Identify foods that trigger negative reactions in your body, such as digestive issues, allergies, or headaches, and eliminate them from your diet entirely. - Elimination Diet
Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.
Ask your clinician about
Named only. Marrow gives no dose and does not recommend these.
From your Food Sensitivities report
Peanut AllergyMore likely
More likely to have peanut allergy based on 780 genetic variants we looked at
Your risk is greater than 93% of the population and lower than 7% of the population.
What this actually is
About 3 million people in the U.S. have a nut allergy.
Risk factors involve contact with peanuts.
Verify food content in restaurants, and read all food packaging labels to minimize risk.
From your Diet & Nutrition report & Food Sensitivities
Egg AllergyMore likely
More likely to have an egg allergy based on 373 genetic variants we looked at
Your risk is greater than 80% of the population and lower than 20% of the population.
What this actually is
Egg allergies are relatively common, especially in children, and can be very severe.
A person usually develops a reaction to one or more egg white proteins.
Luckily, the allergy often fades with age [R, R].
What you can do
- Elimination Diet
Begin by removing foods you suspect might be causing adverse reactions for 2-3 weeks.

Essential Amino AcidsIncreased need
Higher predisposition than average

Eating HabitsIncreased need
Higher predisposition than average
From your Diet & Nutrition report
PNPLA3 (Lipids/ Liver Health)Worse genetics
Higher predisposition than average
What this actually is
The PNPLA3 (patatin-like phospholipase domain-containing 3) gene encodes a protein called adiponutrin with key roles in lipid metabolism.
Adiponutrin helps regulate the development of fatty cells and the production and breakdown of triglycerides in fatty and liver cells.
From your Diet & Nutrition report
Omega-6:Omega-3 RatioIncreased need
Higher predisposition than average
From your Diet & Nutrition report
A further 8 results were also flagged for attention. They are listed below and explained in full in the technical version of this report.
Where your genetics are working for you
Not everything in a genetic report is a warning. These came back protective or better than average.
Metabolic SyndromeLess likely
Less likely to have metabolic syndrome based on 636,870 genetic variants we looked at
Your risk is greater than 1% of the population and lower than 99% of the population.
What this actually is
Factors that might increase the risk of developing metabolic syndrome include: Age: Risk increases with age.
A history of diabetes in one's family.
A history of gestational diabetes or having given birth to a baby weighing more than 9 pounds.
From your Blood Sugar Control report
Sugar CravingsLess likely
Less likely to crave sugar based on 673,476 genetic variants we looked at
Your risk is greater than 20% of the population and lower than 80% of the population.
What this actually is
People who have less sensitive sweet receptors may have a “sweet tooth.” They may prefer sweet foods and eat more of them [R, R, R].

Fats BreakdownBetter
Lower predisposition than average

What to do with this
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Methodology
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
Limitations
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
