Why Genetics Matter for Nutrition
Every individual's body is different, and our genes are a primary reason why. Your DNA contains the specific instructions for how your body interacts with the food you eat, meaning a diet that works for one person may not be optimal for you.
Research shows that genetic variations can make the difference between optimal nutrition and chronic deficiency, even when eating the same foods.
What you'll discover:
- Which vitamins your body struggles to absorb
- How to choose supplements that actually work for your genetics
- Why you might need different amounts of nutrients than others
- Which foods align with your genetic makeup
- How to prevent deficiencies before they impact your health
Inside Your Personalized Report
The Genofit DNA Nutrition Test analyzes multiple genetic variants influence nutrient metabolism, including:
BCO1 — Vitamin A Conversion
Controls how well you convert plant carotenoids (like beta-carotene from carrots) into active vitamin A. Some people excel at this conversion. Others need vitamin A from animal sources or supplements because their plant-to-vitamin-A pathway doesn't work efficiently.
NBPF3 — Vitamin B6 Processing
Determines how quickly your body uses up vitamin B6. Fast processors might need B6 more frequently, while slow processors can maintain levels longer. This affects energy production, brain function, and immune health.
FUT2 — Vitamin B12 Absorption
Influences your gut's ability to absorb B12 from food and supplements. Poor absorbers might need higher doses or specific forms of B12 to maintain healthy levels, regardless of how much they consume.
SLC23A1 — Vitamin C Distribution
Controls how vitamin C moves through your body and stays in your cells. Genetic variants affect whether standard vitamin C doses are enough for your tissues or if you need higher amounts for optimal immune and antioxidant function.
CYP2R1 & GC — Vitamin D System
Work together to activate and transport vitamin D throughout your body. Variants can affect vitamin D status regardless of sun exposure or supplementation, influencing bone health, immunity, and overall wellbeing.
APOA5 — Vitamin E Levels
Regulates vitamin E concentrations in your blood. Some variants lead to naturally lower vitamin E levels, affecting antioxidant protection and potentially requiring targeted supplementation.
MTHFD1 & MTHFR — Folate Activation
Control how your body processes folate into its active form. Up to 40% of people have variants that reduce folate efficiency, affecting everything from energy to cardiovascular health. This determines whether you need regular folate or the active methylfolate form.
TF & TMPRSS6 — Iron Management
Regulate iron absorption from food and iron transport in your blood. These variants explain why some people easily maintain iron levels while others struggle with deficiency despite eating iron-rich foods.
NOS3 — Omega-3 Response
Determines how effectively your body uses omega-3 fatty acids for heart health and inflammation control. Some people get maximum benefits from standard doses, while others need higher amounts for the same effects.
