Caffeine , Sodium Benzoate & Nutrient Depletion
Also searched as Caffeine and Sodium Benzoate. What the clinical evidence reports, what it may mean, and what to discuss with your pharmacist.
Caffeine , Sodium Benzoate has been associated with depletion of POTASSIUM. This does not mean a deficiency will occur — it means these are worth knowing about and, if you take Caffeine , Sodium Benzoate long-term, worth raising with your pharmacist or healthcare provider.

Reported nutrient depletions with Caffeine , Sodium Benzoate
Each record below is shown as published in our licensed clinical database, with its evidence rating and citations. Expand a section for food sources and talking points.
POTASSIUM
Moderate DepletionMETHYLXANTHINES
Methylxanthines like theophylline can reduce serum potassium levels, possibly by increasing intracellular uptake of potassium. Hypokalemia is most likely to occur after acute overdose of these drugs. However, reduced potassium levels can occur with therapeutic doses, and the incidence and degree of hypokalemia increases with increasing serum theophylline levels. Monitor potassium levels in people with other risk factors for hypokalemia. For information on foods that are rich in potassium, see our chart.
Potassium is a mineral your heart, muscles, and nerves depend on to work properly, and caffeine and sodium benzoate belongs to a drug class called methylxanthines that can nudge potassium out of the bloodstream and into your cells, effectively lowering the level your body has readily available. This effect is more pronounced at higher doses, but it has also been reported at normal therapeutic doses, and a 'Moderate Depletion' rating means this is worth taking seriously rather than brushing aside. If you have other reasons your potassium might already run low (such as taking a water pill or not eating many potassium-rich foods), it is worth bringing up with your doctor or pharmacist so your levels can be kept an eye on.
What Potassium does & food sources
Potassium keeps nerve signals, muscle contractions, and heart rhythm working normally.
Common food sources:
- Bananas and citrus fruits
- Potatoes and sweet potatoes
- Beans and lentils
- Tomatoes and leafy greens

What to discuss with your clinician
Potassium is routinely checked with basic blood work. If you take a medication associated with potassium loss (like some diuretics), ask your provider how often your electrolytes should be monitored.

Supplement considerations
Do not start potassium supplements on your own. Both low and high potassium can affect heart rhythm, and several common medications (ACE inhibitors, ARBs, potassium-sparing diuretics) raise potassium.
Do not start or stop medications or supplements without professional guidance — supplements can interact with prescription medications.

Caution: Potassium supplementation can be dangerous in kidney disease or alongside potassium-raising medications — this is a decision for your prescriber, guided by lab results.

More about Caffeine , Sodium Benzoate
What drug-induced nutrient depletion means
Some medications can, over time, lower the levels of certain vitamins, minerals, or other nutrients — through reduced absorption, increased loss, or changes in how the body uses them.
Association is not deficiency
An entry here means a depletion has been reported or studied — not that it happens to everyone, or that you are deficient. Dose, duration, diet, and your own health all matter.
Evidence varies by pair
Some drug–nutrient links (like metformin and vitamin B12) are well studied; others rest on limited or preliminary research. Each entry shows the evidence rating from our licensed clinical database.
When to ask about labs
If you take an associated medication long-term, ask your healthcare provider whether monitoring is appropriate for you. Not everyone needs testing — your provider can weigh your dose, duration, and symptoms.
Don't self-supplement blindly
Supplements are not risk-free: some can interact with medications, and some (like potassium or magnesium) can be risky with kidney disease. Talk to your pharmacist before adding anything.
Never stop a medication over this
These medications are prescribed for good reasons, and the benefit usually far outweighs a manageable nutrient consideration. Any change belongs in a conversation with your prescriber.
Food first, usually
For many nutrients, a varied diet covers the gap. Each entry lists common food sources; a supplement is a decision to make with your pharmacist or provider, not a default.
