Nutrition planning, particularly personalized nutrition, is vital in maintaining optimal health and well-being. Customizing nutrition plans may help individuals meet nutritional needs based on factors such as age, genetics, and activity level, and medical concerns or nutritional deficiencies. Many Americans may have one or more nutrient deficiencies.
Nutrient deficiency tests are highly beneficial in identifying specific dietary concerns. This article explores how tailored diets using nutrient deficiency testing can optimize patient health outcomes.

What Are Nutrient Deficiency Tests?
Nutrient deficiency tests may help identify nutrients that could be lacking due to dietary habits, lifestyle factors, or other health considerations. Examples of the various types of nutrient deficiency tests include:
- Blood tests
- Urine testing
- Hair analyses
- Stool tests to assess malabsorption
A healthcare professional orders nutrient tests that identify potential deficiencies in essential nutrients, such as vitamins, minerals, and fatty acids. Examples of common nutrients evaluated during deficiency testing include:
- Iron
- Vitamin D
- Vitamin B12
- Vitamin B6
- Folate
- Other B vitamins
- Magnesium
- Omega-3 fatty acids
- Protein
- Vitamin A
- Calcium
- Iodine
- Zinc
- Selenium
- Copper
Identifying nutrient needs early may help manage wellness and support overall health.
The Science Behind Nutrient Deficiencies and Health
Nutrient levels can affect overall health and well-being, as each nutrient supports specific structures and functions within the body. Examples of side effects of insufficient nutritional intake include:
- Weakened bones
- Low energy levels
- Weakened immune system
- Muscle aching or weakness
- Numbness and tingling in the feet or hands
- Impaired cognitive functioning
- Dizziness or lightheadedness
- Mood changes
- Pale skin
- Thinning hair
- Brittle nails
- Slow-healing wounds
- Easy bruising
- Bone tenderness
- Joint pain
- Degenerative diseases
- Poor growth and development in children
- Intellectual impairment
- Mental health concerns
For example, low iron may contribute to feelings of fatigue, and lower levels of vitamin B12 and calcium may affect nerve health and bone strength.
Nutrient deficiencies might develop because of poor dietary habits, unhealthy lifestyle habits, genetics, or specific health conditions that affect nutrient absorption.
Researchers report that deficiencies and excessive nutrient intakes can be harmful, affecting more than 2 billion people — particularly pregnant women and young children.
Studies suggest that nutrient imbalances may be associated with factors affecting cardiovascular, cognitive, and neuromuscular health, especially as people age.
The Global Leadership Initiative on Malnutrition (GLIM) guidelines emphasize the vital role of nutrition assessments in addressing malnutrition in individuals with chronic diseases.
Personalized Nutrition: A Targeted Approach to Health Optimization
Personalized nutrition plans (using targeted dietary approaches) are superior to general dietary guidelines because individuals have specific nutritional needs. While basic nutrition recommendations exist, there are more than just one-size-fits-all approaches when planning meals or recommending dietary supplements.
The potential benefits of using nutrient data to create tailored meal plans may include support for energy, balanced moods, a healthy immune response, and a reduction in nutrient imbalances that could potentially lead to deficiency-related medical concerns.
Tailoring Diets to Correct Nutrient Deficiencies
Healthcare providers may develop individualized nutrition plans informed by nutrient test results to help support overall wellness.
Examples of dietary changes to make for specific nutrient deficiencies include:
- Vitamin D: Increase sunlight exposure and vitamin D-rich foods, such as fortified orange juice, milk, yogurt, plant milk, fortified cereals, mushrooms, and fatty fish.
- Iron: Incorporate iron-rich foods like lean red meats, chicken, oysters, fortified cereals, legumes, dark leafy greens, and tofu
- Magnesium: Add high-magnesium options like nuts, seeds, cereals, whole grains, green vegetables, legumes, potatoes, soymilk, and yogurt.
- Vitamin B12: Focus on vitamin B12-rich foods like meat, poultry, seafood, fish, nutritional yeast, fortified cereals, milk, yogurt, and eggs.
- Omega-3 fatty acids: Eat foods high in omega-3s, including fatty fish (salmon, tuna, herring, sardines), flaxseeds, walnuts, chia seeds, soybean oil, canola oil, soybean oil, and foods fortified with omega-3s — such as milks, yogurts, juices, eggs, and infant formulas.
Dietary supplements can be an additional source of vitamins, minerals, and omega-3 fatty acids when included under professional guidance.
It's highly beneficial to include food sources of essential nutrients plus dietary supplements under medical supervision, with routine monitoring of patient progress. Dietary habits and supplement regimens should also be adjusted as needed based on follow-up nutrient deficiency testing.
The Role of Functional Medicine in Personalized Nutrition
Functional medicine takes a holistic approach, focusing on diet, supplements, exercise, and lifestyle habits to help maintain health and wellness.
Functional medicine uses nutrient deficiency testing as a component of broader health optimization. It emphasizes the collaboration between dietitians, functional medicine practitioners, doctors, and other healthcare professionals to ensure long-lasting success.
Limitations and Considerations in Using Nutrient Deficiency Tests
Potential challenges and limitations of nutrient testing include accessibility and cost. In the long term, nutrient testing may be a cost-effective addition to health assessments, potentially helping to reduce issues related to nutrient imbalances.
Other possible concerns include overreliance on nutrient testing without considering the overall health context of each patient's unique situation.
To make the most of nutrient deficiency testing, individuals are encouraged to work with a qualified healthcare provider to ensure safe and appropriate use.
The Future of Personalized Nutrition and Nutrient Deficiency Testing
The future of personalized nutrition and deficiency testing is ever-changing. Technological advancements in nutrient testing and meal plans include at-home nutritional testing kits, wearable devices, AI food plans, and data analytics that help improve dietary recommendations and create personalized nutrition plans as accurately as possible.
Interest is growing in personalized health solutions that incorporate holistic and functional approaches to care. The widespread adoption of customized nutrition plans in preventive healthcare is highly likely.
