HelloPharmacist Scorecard of Citric Acid 590 mg by Dr. Clark Store

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: citric acid, 590 mg per capsule. The capsule itself is made from gelatin.

Does it work?

No specific claim
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
General wellness

This Citric Acid product is marketed for general wellness, not a specific health condition, so there's no single claim to grade — see Citric Acid's own graded uses on its monograph.

Why this rating?
  • The label markets general wellness (“supports digestive health”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.

The evidence for citric acid isn't established in the data we hold. The supplement is marketed for acne, aging skin, dry mouth, kidney stones, melasma, and muscle cramps, but we have insufficient reliable evidence to rate how well it works for any of those uses.

The evidence, ingredient by ingredient Citric Acid

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Citric acid is generally recognized as safe in the small amounts found in foods and most supplements. However, this product is a concentrated medicinal dose, not a food amount — so check with your doctor before you start it.

When citric acid is applied to skin (as in peels or topical products), it's usually well tolerated at low concentrations, though it can cause mild irritation, sun sensitivity, and tingling. High concentrations or prolonged contact can cause serious burns and skin damage.

Alpha hydroxy acids like citric acid also increase your skin's sensitivity to the sun, which can raise your risk of sun damage and, with long-term use, skin cancer risk.

Side effects, ingredient by ingredient Citric Acid

Meds to double-check

No known interactions
Known Interaction Concern · database check
No known interactions

No medication interactions are currently documented for the matched ingredients — that isn't a guarantee none exist.

Why this rating?
  • None of the 1 matched ingredient has a documented medication interaction on file.

No interactions are documented for citric acid in our data, but it's still wise to talk with your doctor or pharmacist before you start — concentrated citrate supplements are a different story from food amounts, and they may have effects your healthcare provider needs to know about.

The bottom line

Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. No medication interactions are currently documented, and safety information is well characterized.

Citric Acid 590 mg might appeal to you if you're exploring supplements for kidney stones, muscle cramps, or skin concerns — but the evidence for how well it works isn't established. Because this is a concentrated supplement (not just food citric acid), talk with your doctor or pharmacist before you take it, especially if you have kidney or heart concerns or take other medications.

Citric Acid 590 mg by Dr. Clark Store: Common Questions

Does Citric Acid 590 mg by Dr. Clark Store interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Citric Acid 590 mg. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Citric Acid 590 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is citric acid safe to take if I'm pregnant or breastfeeding?
The data rates citric acid as likely safe during pregnancy and lactation. That said, because this is a concentrated supplement and not just food amounts, run it by your doctor or pharmacist for personalized advice about whether it's right for you.
What are the side effects of this supplement?
Topically (on skin), citric acid is generally well tolerated but can cause mild irritation, sun sensitivity, and tingling. When applied in high concentrations or left on skin too long, it can cause serious burns and damage. The data doesn't detail side effects from taking the capsule by mouth — check with your doctor about what to expect.
Does citric acid actually help with kidney stones?
The evidence for citric acid and kidney stones isn't established in our data. We have insufficient reliable evidence to rate whether it works for that use. Talk with your doctor about whether it makes sense for your situation.
Will this affect my medications?
No interactions are documented for citric acid in our data. Even so, because this is a concentrated supplement, mention it to your doctor or pharmacist to make sure it plays well with your personal health picture.
Can I use this if I have kidney or heart problems?
The data doesn't cover that specifically. Because citrate supplements can affect the body differently than food citric acid, talk with your doctor or pharmacist before you start — they know your health and can advise you.
