Gut & Digestive Health
Nutritional Deficiency
A nutritional deficiency happens when your body is not getting or absorbing enough of the vitamins, minerals, protein, or healthy fats it needs to function well.
Common Symptoms
- Fatigue and low energy that does not improve with sleep
- Brain fog, trouble focusing, memory slips
- Hair loss, brittle nails, or dry skin
- Muscle cramps or weakness, tingling, or restless legs
- Frequent infections, slow wound healing, or easy bruising
- Shortness of breath, dizziness, or feeling cold easily
- Digestive changes, bloating, poor appetite, or nausea
Likely Root Causes and Contributors
- Insufficient intake from restrictive eating, low appetite, or lack of nutrient-dense foods
- Malabsorption issues such as gut imbalance, inflammation, celiac disease, or chronic digestive problems
- Higher nutrient needs during stress, pregnancy, illness, or recovery
- Medication effects that interfere with nutrient absorption
- Lifestyle factors like smoking, alcohol overuse, or chronic stress that deplete stores
- Age related changes that make it harder to absorb key vitamins and minerals
Patient Pain Points We Often Hear
“I am tired all the time, but no one can explain why.”
“My symptoms seem random, and every test keeps coming back normal.”
“I feel like my body is running on low fuel, no matter how healthy I try to be.”
Our Approach to Healing
How We Map, Treat, and Sustain Real Recovery from Nutritional Deficiency with the LAM Method™
Nutritional deficiencies are rarely random. They usually reflect how your body has been eating, digesting, absorbing, and using nutrients under daily stress. Our approach to healing uses the three phases of LAM Method™: Learn the Why, Address the Root, Maximize Longevity. Here’s how we use the LAM Method™ to address Nutritional Deficiency:
Phase 1 of LAM Method™
Learn the Why of Nutritional Deficiency
We begin with the full picture: energy, sleep, mood, digestion, appetite, food patterns, medications, stress load, and how long symptoms have been present. We focus on patterns, not just a single lab value.
Core Bloodwork for Nutrient Status
These are the foundations for evaluating nutritional deficiency:
- Iron panel
- Vitamin B12 and folate
- Vitamin D
- Magnesium, zinc, selenium, and iodine
- Calcium and electrolytes
- Inflammation markers and Autoimmune Markers
Tests That Help Explain Why Deficiencies Occur
- Comprehensive stool test
- Organic Acid Test (OAT)
- Micronutrient testing
- Thyroid panel (TSH, Free T4, Free T3 ± antibodies)
- Blood sugar markers (fasting glucose, insulin, A1c)
- Mycotoxin or heavy metal testing

Phase 2 of LAM Method™
Address the Root of Nutritional Deficiency
Targeted Supplement Support
Supplements are selected based on labs and introduced gradually.
Common priorities may include:
- Iron, when ferritin or iron markers are low
- B vitamins, including B12 and folate, for energy and nervous system support
- Vitamin D, when levels are suboptimal
- Amino Acids: Provide the building blocks for protein, supporting tissue repair, neurotransmitter balance, and recovery from nutritional deficiencies.
- Minerals: Replenish essential cofactors your body needs for energy, metabolism, and cellular function, correcting underlying nutritional deficiencies.
- IV Nutrient Therapy: Rapidly restores deficient nutrients by delivering them directly into the bloodstream for optimal absorption and replenishment.
This information is educational, not a prescription. Your actual plan is always individualized, adjusted slowly, and refined based on how your body responds.
Phase 3 of LAM Method™
Maximize Longevity
Lifestyle Foundations
We start with practical changes that support nutrient repletion:
- Prioritize iron-, B12-, folate-, magnesium-, zinc-, and protein-rich foods based on the suspected deficiency
- Pair iron-rich foods with vitamin C sources like citrus, berries, or bell peppers to improve absorption
- Reduce nutrient blockers around meals, such as tea, coffee, or excess calcium supplements when iron deficiency is a concern
- Use simple, consistent meals and snacks that combine protein, healthy fats, and mineral-rich foods when low appetite or fatigue makes eating harder
- Support absorption by addressing digestive issues, food intolerances, chronic bloating, or low stomach acid that may limit nutrient uptake
- Simple maintenance routines to prevent future deficiencies
- Periodic labs to track trends before symptoms return
- Guidance during illness, stress, or life changes that raise nutrient needs
NEM Response Circuits
How Your Body Regulate Stress
Your body handles stress through six interconnected circuits. When even one is out of balance, symptoms can show up in your heart, hormones, energy, and more.

Take the QuizFrequently Asked Questions
Can Lam Clinic help with nutritional deficiencies?
Yes. Nutritional deficiencies often aren’t just from “not eating enough.” Chronic stress can disrupt your NEM Stress Response, lowering stomach acid, digestion, absorption, and cellular use of nutrients. We identify your root drivers and overloaded circuits, then create a personalized plan to rebuild function, energy, and long-term balance.
Can nutritional deficiencies happen even if I eat healthy?
Yes, we see this often. Gut issues, low stomach acid, chronic stress, certain medications, or past restrictive diets can all block proper absorption, even when your food choices look good on paper.
Can nutritional deficiencies affect mood and anxiety?
Yes, low levels of nutrients like B vitamins, iron, vitamin D, and magnesium can make you feel more anxious, low, or “on edge.” When we replenish them properly, many people describe feeling more stable, clear, and resilient.
Do you offer virtual visits and where are you located?
Yes. We offer secure telehealth visits worldwide and in person care at our clinic in Tustin, California. We proudly serve patients across Orange County including Irvine, Santa Ana, Orange, Costa Mesa, and Anaheim, as well as individuals throughout the United States and internationally who seek personalized nutritional and NEM stress response guidance from the comfort of home.
The Lam Family has helped thousands recover from fatigue and stress for years.
Using advanced diagnostics and whole-body care, the Lam family looks beyond routine labs to uncover the real reasons behind fatigue—like adrenal stress, hormone imbalance, and nutrient depletion. Then, they create a personalized plan to help you heal fully and feel like yourself again.
The Pioneer of Root-Cause Healing & Whole Person Care
Before adrenal fatigue was widely understood, Dr. Michael Lam, M.D. led the way—developing one of the first clinical approaches to diagnose and treat it. His bestselling book, Adrenal Fatigue Syndrome, became a lifeline for patients around the world. Today, his children—Dr. Carrie Lam and Dr. Jeremy Lam—carry that legacy forward, building on his foundation with advanced diagnostics and whole-person care for lasting recovery.
