How to Know If You Have Nutritional Deficiencies: Signs, Testing, and Next Steps
Most people think they’re eating “healthy enough.” But even with a balanced diet, nutritional deficiencies are surprisingly common and can quietly affect your energy, mood, performance, and long-term health. Whether you’re an athlete, executive, or busy parent, understanding your body’s nutrient status can be the difference between just getting through the day and actually thriving.
At APEX Performance Wellness & Rehab in Tigard, Oregon, our Nutrition Services go beyond calorie counting. We help you uncover what your body really needs through data-driven analysis, education, and tailored programs like our 12 Week Nutrition Challenge and 1:1 VIP Nutrition Coaching.
Here’s how to identify if you might have nutritional deficiencies and what to do about it.
Common Signs of Nutritional Deficiencies
Your body gives early warning signs when key nutrients are low. Recognizing them can help you act before they turn into bigger health issues.
- Low Energy and Fatigue
- Could indicate iron, B12, or magnesium deficiency.
- You may feel tired despite getting enough sleep or experience energy crashes during the day.
- Frequent Illness or Poor Immunity
- Low levels of vitamins C, D, and zinc can reduce your body’s ability to fight off illness.
- If you’re getting sick often, your immune system may be undernourished.
- Hair Loss, Brittle Nails, or Dry Skin
- Common with deficiencies in biotin, zinc, omega-3s, or protein.
- Your body prioritizes vital organs first, leaving hair and nails as secondary when nutrients are lacking.
- Mood Changes and Brain Fog
- Nutrient deficiencies can affect serotonin and dopamine production, impacting focus and mood.
- B vitamins, magnesium, and omega-3s are crucial for cognitive health.
- Muscle Weakness, Cramps, or Slow Recovery
- Inadequate protein, vitamin D, or magnesium can hinder muscle performance and recovery.
- This is especially common in active individuals or those under stress.
- Poor Sleep Quality
- Magnesium and vitamin B6 play key roles in sleep regulation.
- If you struggle to fall or stay asleep, nutrition could be part of the problem.
Why Nutritional Deficiencies Happen
Even people who eat “clean” can experience deficiencies. Common causes include:
- Stress: Chronic stress depletes magnesium, B vitamins, and vitamin C.
- Restricted Diets: Vegan, low-carb, or low-fat diets can unintentionally limit nutrient intake.
- Digestive Issues: Gut health affects how well nutrients are absorbed.
- Poor Food Quality: Modern farming practices have reduced nutrient density in produce.
- Busy Lifestyles: Skipping meals, eating out, or inconsistent meal timing can all add up.

FAQs About Nutritional Deficiencies
Q: Can I fix a deficiency through food alone?
A: In many cases, yes, but some deficiencies require supplements for faster correction. We can help determine the best plan for your situation.
Q: How long does it take to correct a deficiency?
A: Depending on the nutrient and your consistency, improvements can appear within weeks, though full restoration may take several months.
Q: Can I be deficient even if I eat “healthy”?
A: Absolutely. Nutrient absorption, stress, and lifestyle habits all play a role in how well your body utilizes what you eat.
Q: Are supplements really necessary?
A: Supplements shouldn’t replace whole foods, but they’re powerful tools for filling gaps, especially with trusted brands like Thorne (get a lifetime 25% discount!).
