Are You Nutrient Deficient? Signs You Might Be Missing Key Vitamins

Written by Kristy Beard, MSN, APRN, FNP-C — Board-Certified Family Nurse Practitioner and Founder of Elevate Health and Wellness, serving patients across the Gulf Coast in Gautier, MS and Foley, AL.

The Hidden Epidemic of Nutritional Deficiency

You don't have to live in poverty to be nutritionally deficient. According to the CDC's National Health and Nutrition Examination Survey (NHANES), nutritional deficiencies are widespread in the United States — even among people who eat regularly. Processed food consumption, poor soil quality, gut absorption issues, chronic stress, certain medications, and intense exercise all contribute to nutrient depletion. On the Gulf Coast, heavy sweating in summer heat accelerates mineral loss even further.

Vitamin D: The Most Common Deficiency You've Never Thought About

Vitamin D deficiency affects an estimated 42% of American adults, according to research published in Nutrition Research. Despite living in one of the sunniest regions in the country, Gulf Coast residents are frequently deficient — because sun exposure, skin tone, age, obesity, and sunscreen use all affect vitamin D conversion. Low vitamin D is linked to immune dysfunction, depression, fatigue, bone loss, and increased cancer risk.

Vitamin B12: The Energy Vitamin

B12 deficiency is particularly common in adults over 50, vegetarians and vegans, patients on metformin or proton pump inhibitors, and anyone with gut absorption issues. Symptoms include profound fatigue, tingling in the hands and feet, brain fog, mood changes, and anemia. Because B12 is stored in the liver, deficiency develops slowly and can go unnoticed for years.

Magnesium: Running Low in 48% of Americans

The NIH estimates that approximately 48% of Americans consume less than the recommended daily amount of magnesium — a mineral involved in over 300 enzymatic reactions including energy production, muscle function, nerve signaling, and blood pressure regulation. Low magnesium manifests as muscle cramps, sleep disruption, anxiety, headaches, and fatigue. Gulf Coast residents who sweat heavily are at particular risk.

How Elevate Tests and Treats Deficiencies

Kristy Beard, MSN, APRN, FNP-C uses comprehensive nutritional lab panels to identify specific deficiencies rather than guessing. Testing may include vitamin D, B12, folate, magnesium, zinc, and iron studies. Once deficiencies are identified, a targeted repletion plan is created — which may include oral supplementation, dietary modifications, B12 injections, or IV micronutrient therapy for faster restoration.
