HelloPharmacist Scorecard of Corn Silk Extract by BulkSupplements.com

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: corn silk stigma extract — the fine, thread-like strands from the corn ear. The inactive ingredient is maltodextrin, which is a filler that helps stabilize the powder form.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Corn Silk's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: urinary tract and bladder health.
  • We looked for evidence on: Nocturnal enuresis, Prostatitis, Urinary tract infections (UTIs), Kidney stones (nephrolithiasis), urinary irritation, fluid retention — and 1 related terms.
  • The closest evidence on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Kidney stones (nephrolithiasis) (Natural Medicines).
  • Also on file: Corn Silk is rated "Insufficient Reliable Evidence To Rate" for Prostatitis, Urinary tract infections (UTIs), Nocturnal enuresis.

The evidence we hold doesn't establish how well corn silk extract works for the conditions listed — angina, heart disease, heart failure, depression, diabetes, and fatigue all show insufficient reliable evidence to rate. That doesn't mean it doesn't work; it means the research isn't solid enough yet to make a claim either way.

The evidence, ingredient by ingredient Corn Silk

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.

Corn silk extract is generally well tolerated for short-term use, but human safety data are limited overall. The most common side effects from oral use are low potassium (hypokalemia) and low sodium (hyponatremia), especially with longer-term use.

Topical application (on skin) can cause rash or hives in some people. During pregnancy, there's not enough reliable safety data, so it's best avoided.

While breastfeeding, safety is unknown — talk with your doctor or pharmacist before using it.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Corn Silk Extract might be worth considering if you're exploring natural options for heart or blood sugar support, but it's not a first choice if you take blood pressure pills, water pills, steroids, diabetes medications, or warfarin. Check with your pharmacist or doctor before starting, especially if you're on any chronic medications.
