Nutrients That May Be Depleted By Drugs

Medicine, pharmaceuticals, drugs. Whatever you call them, medications have become a fact of life. There's not many of us that can say that we've never taken any type of prescription medicine.

While medications are sometimes necessary and help to alleviate symptoms, taking pharmaceuticals for a long time may cause or contribute to nutrient depletions.

Some of the most common prescriptions medications that may cause nutrient depletions include antibiotics, blood pressure medications, and certain over-the-counter drugs.


With the CDC admitted that antibiotics are overprescribed, there's a huge chance that you or a loved one may have taken a round or two of antibiotics in the past. You've maybe even taken antibiotics unnecessarily.

Now I have absolutely nothing against antibiotics taken when they are needed but when there is an overuse of antibiotics, then a whole host of health problems can arise ranging from harmful changes in the gut microbiome [1] to mental confusion and delirium[2].

That's not the only negative impact antibiotic use may inflict on the body. Certain antibiotics have been linked with nutrient deficiencies. This means that the antibiotic itself has been shown to cause a loss of this nutrient or reduce the absorption of the nutrient in the body.

Here is a quick guide to some nutrient deficiencies linked to antibiotics:

Amoxicillin, Penicillin, Keflex Nutrient Depletions

Antibiotics like amoxicillin work by stopping bacteria from growing by damaging bacterial cell wall creation. Some nutrient deficiencies associated with amoxicillin and similar antibiotics include:

  1. B vitamins

  2. Vitamin K

  3. Vitamin C

Tetracycline Antibiotics like Doxycycline & Minocycline

Tetracycline antibiotics work by preventing the growth and spread of bacteria. Nutrients depletions caused by tetracycline antibiotics include:

  1. Calcium

  2. Magnesium

  3. Iron

  4. Zinc

  5. Vitamins B6 and B12


Neomycin works by stopping bacterial proteins from being made which leads to bacterial death. Here are some of the most common nutrients depletions.

  1. Beta-carotene (vitamin A precursor)

  2. Calcium

  3. Magnesium

  4. Iron

  5. Potassium

  6. Vitamins A and B12

Blood Pressure Medications

Antibiotics aren't the only medications that are associated with nutrient depletions. Common blood pressure medicines may also cause a diminishing absorption of certain nutrients.

Calcium Channel Blockers

Calcium channel blockers work by stopping calcium from entering the cells of the heart. This stops the heart from squeezing harder which causes the blood pressure to increase.

  1. Vitamin D

Thiazide Diuretics

Thiazide diuretics work by blocking sodium and chloride channels in the kidney which helps to reduce blood pressure.

  1. Magnesium
