9 Prescription Medications That May Deplete Key Nutrients

9 Prescription Medications That May Deplete Key Nutrients

If you take one or more prescription medications, this is something worth knowing.

Many commonly prescribed drugs—while helpful and often necessary—can reduce certain vitamins and minerals your body needs to function optimally. Over time, these nutrient depletions may contribute to symptoms people often don’t realize are connected to their medications.

In this article, we’ll cover:

  • 9 common types of prescription medications

  • The key nutrients they may deplete

  • Why this matters for energy, gut health, and overall well-being

  • What to do without stopping or changing your medications

Important disclaimer:

This article is for educational purposes only. Never stop, start, or change a prescription medication without consulting your healthcare provider. The information below may not apply to everyone (and may not be safe for everyone).

 

 

Why Medication-Related Nutrient Depletion Matters

Medications can affect nutrient levels in several ways:

  • Altering digestion or absorption

  • Increasing nutrient excretion

  • Interfering with metabolism or storage

This doesn’t mean medications are “bad.” It simply means that long-term use can create unintended nutritional gaps if those nutrients aren’t being replenished through diet or supplementation.

 

 

1. Statin Medications

Common examples:

Lipitor (atorvastatin), Crestor (rosuvastatin), simvastatin, pravastatin, lovastatin

Statins are among the most commonly prescribed medications and are primarily used to lower LDL cholesterol.

Key Nutrients Depleted

  • Coenzyme Q10 (CoQ10)

  • Vitamin C

  • Glutathione

CoQ10 is essential for:

  • Cellular energy production

  • Muscle function

  • Heart and brain health

This depletion may help explain why some people experience muscle weakness or fatigue while on statins.

 

 

2. Metformin (Diabetes Medication)

Metformin is a mainstay treatment for type 2 diabetes and has strong evidence for improving blood sugar control.

Key Nutrients Depleted

  • Vitamin B12

  • Folate (vitamin B9)

Vitamin B12 deficiency is especially important to monitor, as low levels may:

  • Worsen diabetic neuropathy

  • Contribute to fatigue, numbness, or tingling

 

 

3. Diuretics (“Water Pills”)

Common examples:

Hydrochlorothiazide (HCTZ), furosemide

Often prescribed for high blood pressure or fluid retention.

Key Nutrients Depleted

  • Potassium

  • Magnesium

  • Sodium

While sodium loss is part of how these medications work, potassium and magnesium are critical for heart rhythm, muscle function, and nervous system health.

Note: Potassium-sparing diuretics (like spironolactone) work differently and may increase potassium levels instead.

 

 

4. ACE Inhibitors

Common examples:

Lisinopril, benazepril, enalapril

Used for blood pressure, heart failure, and kidney protection.

Key Nutrient Effects

  • May reduce Coenzyme Q10

  • May increase potassium levels

This combination makes monitoring nutrients especially important.

 

 

5. Proton Pump Inhibitors (PPIs)

Common examples:

Prilosec (omeprazole), Nexium (esomeprazole), pantoprazole

PPIs reduce stomach acid, which can be helpful short term—but stomach acid is essential for nutrient absorption.

Nutrients Commonly Affected

  • Vitamin B12

  • Vitamin C

  • Calcium

  • Iron

  • Magnesium

Long-term use may impair digestion and absorption of these nutrients.

 

 

6. NSAIDs (Non-Steroidal Anti-Inflammatory Drugs)

Common examples:

Ibuprofen (Advil), naproxen (Aleve), aspirin

Potential Effects

  • Reduced iron and folate

  • Damage to the gastrointestinal lining with chronic use

Some research also suggests NSAIDs may reduce melatonin production, potentially affecting sleep quality.

 

 

7. Warfarin (Coumadin)

A blood thinner prescribed to prevent clots.

Key Nutrient Affected

  • Vitamin K (especially K2)

Critical note:
Never change vitamin K intake or warfarin dosing without medical supervision. This medication requires careful monitoring.

 

 

8. SSRIs (Selective Serotonin Reuptake Inhibitors)

Common examples:

Zoloft (sertraline), Prozac (fluoxetine), Paxil (paroxetine), Lexapro (escitalopram)

Used for depression and anxiety.

Potential Nutrient & Electrolyte Effects

  • Reduced sodium levels

  • Long-term changes in serotonin receptor sensitivity

Over time, receptor desensitization may reduce effectiveness and contribute to side effects in some individuals.

 

 

9. Oral Contraceptives (Birth Control Pills)

Birth control pills have been associated with multiple nutrient depletions.

Nutrients Commonly Affected

  • Folic acid

  • Vitamins B2, B6, B12

  • Vitamins C and E

  • Magnesium

  • Zinc

  • Selenium

These nutrients play important roles in:

  • Hormone balance

  • Energy production

  • Immune and gut health

 

 

What Should You Do With This Information?

This is not a call to:

  • Stop medications

  • Panic

  • Take dozens of supplements

It is a reminder to:

  • Be aware of potential nutrient gaps

  • Discuss labs or supplementation with your provider

  • Support your body while using necessary medications

Final Thoughts

Prescription medications save lives and improve quality of life—but they don’t operate in isolation.

Understanding how they interact with nutrients empowers you to:

  • Ask better questions

  • Address root causes of symptoms

  • Support long-term health
