Most Common Nutrient Deficiencies I See In My Practice

Many patients come to me on a multivitamin. I am actually not a big fan of supplementing with multivitamins because they contain small amounts (and often poorly absorbed forms) of vitamins and minerals. Rather than supplement with multivitamin, I am an advocate of a colorful diet rich in vitamins and minerals (think color of the rainbow on your plate). And what you don’t get enough of in your diet, I recommend patients supplement with individual nutrients in which they are deficient-the best forms and adequate dosages of the nutrients of course. Most common deficiencies I see in my practice are:
1. Magnesium
Signs of magnesium deficiency:
- Irregular or fast heart beat
- Muscle cramps (Charlie horses!)
- Chocolate cravings
- Restlessness
- Headaches
- Menstrual cramps
- Insomnia
- Anxiety
Food sources- Dark chocolate, tofu, black eyed peas, millet, red beans, beet greens, seeds, nuts, green leafy vegetables, buckwheat
2. Zinc
Signs of zinc deficiency:
- White spots on fingernails
- Ridged nails
- Poor sense of smell or taste
- Decreased immunity
- Acne
- Fatigue
- Poor wound healing
- Poor appetite
- Diarrhea
- Hair loss
Food sources- Pumpkin seeds, red meat, potatoes, soy, oysters, legumes, wheat germ
3. B12
Signs of B12 deficiency:
- Depression
- Anxiety
- Numbness and tingling
- Fatigue
- Sore or inflamed red tongue
- Cracks at the corner of the mouth
- Mouth sores or ulcers
- Weakness
- Irritability
Food sources- Animal products, such as eggs, meat and dairy. Vegetarian source- nutritional yeast.
4. Vitamin D
Signs of vitamin D deficiency:
- Frequent illnesses/poor immune status
- Fatigue
- Depression
- Osteoporosis
- Bone pain
Food sources- Tuna, dairy products, sardines, tuna, salmon, egg yolks all contain some vitamin D. But the best source is the SUN!
5. Essential Fatty Acids (EFAs)
Signs of EFA deficiency:
- Excess ear wax, especially the dark wax
- Seborrheic dermatitis (forehead shiny & scaly, c yellow greasy look which extends into eyebrows, down nose, cheeks, chest
- Dry, brittle hair
- Itchy, dry skin
- Eczema
- Dandruff
- Poor memory or cognition
Food sources- Salmon, sardines, walnuts, flaxseeds, chia seeds, hemp seeds
Testing for Micronutrient Deficiencies
Unfortunately, routine serum testing for micronutrients is inadequate. I recommend intracellular micronutrient testing.
I routinely test for micronutrient deficiencies in patients that struggle with fatigue, malabsorption/digestive issues (such as Crohn’s, IBS or Ulcerative colitis), and infertility. Once we have the results I can make recommendations on the most bioavailable form of the nutrient as well as appropriate dosages for supplementation and associated food sources.
Here is the micronutrient test I have found to be an invaluable part of my practice.
