Introduction: Suboptimal Health Is More Common Than You Think

Have you ever felt tired even after a full night’s sleep? Do you struggle with brain fog, irritability, poor digestion, or frequent illness—but your labs come back “normal”?

You’re not alone.

The truth is, most people today are functioning far below their optimal potential—and one of the most overlooked causes is nutrient and mineral deficiencies. These silent imbalances affect your energy, focus, hormones, immune system, and even your ability to manage stress.

In this blog, we’ll explore:

• Why nutrient deficiencies are so common
• The top symptoms and conditions they contribute to
• How functional medicine identifies and treats them for lasting wellness

Why Are Nutrient and Mineral Deficiencies So Prevalent Today?

Even with access to modern food and supplements, millions of Americans are undernourished at the cellular level. Here’s why:

1. Depleted Soil and Industrial Agriculture

Modern farming practices strip the soil of vital minerals like magnesium, zinc, and selenium, leading to crops with far fewer nutrients than decades ago.

2. Highly Processed Diets

The standard American diet (SAD) is high in calories but low in micronutrients. Ultra-processed foods lack essential vitamins, minerals, and antioxidants your body needs to function.

3. Chronic Stress and Inflammation

Stress increases nutrient demand and depletes key reserves—especially magnesium, B vitamins, and vitamin C—which are needed for adrenal and immune health.

4. Gut Dysfunction

Conditions like leaky gut, IBS, and dysbiosis impair nutrient absorption, even when you’re eating well.

5. Medication-Induced Deficiencies

Common medications—including antacids, metformin, birth control, and statins—can deplete nutrients like B12, magnesium, CoQ10, and zinc over time.

6. Age and Hormonal Decline

As we age, our ability to absorb and metabolize nutrients declines. Older adults are especially prone to B12, vitamin D, and iron deficiencies.

Signs You May Have a Nutrient or Mineral Deficiency

Nutrient imbalances don’t always cause immediate, dramatic symptoms—but they can lead to a cascade of dysfunction. Common signs include:

• Fatigue or low energy
• Brain fog or poor memory
• Mood swings, anxiety, or depression
• Frequent colds or infections
• Muscle cramps, tingling, or weakness
• Brittle nails or hair thinning
• Poor wound healing
• PMS or hormonal imbalances
• Digestive issues (bloating, constipation, acid reflux)

Often these symptoms are dismissed as “normal aging” or treated with medication—while the root cause goes unaddressed.

Most Common Nutrient and Mineral Deficiencies

Let’s break down a few of the most common deficiencies contributing to suboptimal health:

1. Magnesium

Over 60% of people are magnesium deficient. Magnesium is critical for muscle relaxation, sleep, stress regulation, blood pressure, and nerve function.

Low magnesium contributes to:

• Anxiety and irritability
• Constipation
• Headaches and migraines
• High blood pressure
• Insomnia

2. Vitamin D

Vitamin D is essential for immune function, hormone balance, mood, and bone health. Low levels are linked to:

• Autoimmune disease
• Frequent infections
• Depression and SAD
• Chronic pain

Even sunny climates don’t guarantee optimal levels due to indoor lifestyles, sunscreen use, and genetic factors.

3. B12 and Folate

These B vitamins support energy production, red blood cell formation, and neurological function. Deficiencies may cause:

• Fatigue
• Numbness or tingling
• Brain fog or memory loss
• Elevated homocysteine (a cardiovascular risk)

B12 is especially low in vegans, vegetarians, and those on acid-blocking meds.

4. Iron

Iron is essential for oxygen delivery and mitochondrial energy. Low iron can lead to:

• Exhaustion
• Cold intolerance
• Hair loss
• Pale skin
• Dizziness

Women of reproductive age and those with heavy periods are at highest risk.

5. Zinc

Zinc is vital for immune resilience, skin healing, and hormone production. Deficiency symptoms include:

• Frequent illness
• Acne or poor skin healing
• Loss of taste or smell
• Infertility or low testosterone

6. Omega-3 Fatty Acids

These anti-inflammatory fats support brain, heart, and joint health. Signs of deficiency include:

• Depression or mood swings
• Joint pain or stiffness
• Brain fog
• Dry skin or eczema

The Functional Medicine Approach to Deficiency Testing

Unlike conventional care, which may not check for subtle deficiencies, functional medicine uses advanced testing to evaluate nutrient status at the cellular level.

We use:

• Micronutrient panels (serum and intracellular testing)
• Organic acid testing (markers for B vitamins, antioxidants, CoQ10)
• Vitamin D, ferritin, homocysteine, and RBC magnesium
• Hair mineral analysis or heavy metal panels when needed

These tools allow us to uncover what your body is truly missing and create a personalized protocol to restore balance.

How to Rebuild Nutrient Stores for Optimal Health

Once deficiencies are identified, we build a comprehensive plan to correct them safely and effectively.

1. Targeted Supplementation

We use therapeutic doses of:

• Magnesium glycinate or threonate
• Methylated B-complex vitamins
• Liposomal or sublingual vitamin D with K2
• Iron bisglycinate (if needed)
• Zinc carnosine or picolinate
• Fish oil with high EPA/DHA content

Supplements are chosen based on individual lab results, lifestyle, and tolerability.

2. Nutrient-Dense Foods

We emphasize:

• Leafy greens, wild-caught fish, pasture-raised meats
• Colorful vegetables and low-glycemic fruits
• Seeds, nuts, and bone broth
• Fermented foods to support gut absorption

3. Gut Repair and Absorption Support

If nutrient absorption is impaired, we address:

• Leaky gut
• Microbial imbalances (e.g., candida, SIBO)
• Low stomach acid
• Enzyme deficiencies

This often involves:

• Probiotics and prebiotics
• Digestive enzymes
• L-glutamine and soothing herbs

4. Lifestyle Optimization

Chronic stress and poor sleep drain your nutrient reserves. We incorporate:

• Stress reduction techniques
• Better sleep hygiene
• Gentle movement and detox support
• Sunlight exposure and grounding practices

Why “Normal” Labs Don’t Mean You’re Optimal

A common frustration we hear:

“My doctor said everything looks normal, but I still feel off.”

That’s because standard lab ranges reflect population averages—not ideal health. Functional medicine looks for optimal ranges, which are narrower and based on what’s needed for peak function.

For example:

• A vitamin D level of 32 ng/mL is “normal” by lab standards—but optimal is 50–70.
• Ferritin at 15 ng/mL is “acceptable”—but most feel better with levels above 50.

Conclusion: Don’t Settle for Suboptimal

If you’re constantly tired, foggy, anxious, or inflamed—it’s not just in your head. You may be living with silent nutrient and mineral deficiencies that are holding your body back.

At Sheen Vein & Cosmetics, our functional medicine team uses advanced diagnostics and personalized treatment plans to uncover these imbalances and help you truly heal—naturally, at the root.
