HelloPharmacist Scorecard of D-Mannose 500 mg 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.
What’s inside
Full disclosure
This product contains one active ingredient: D-mannose, a simple sugar (carbohydrate) that your body uses and excretes through urine. The capsule itself is made from bovine gelatin, an inactive ingredient that holds the D-mannose together.
Does it work?
Strong evidence
D-mannose is likely effective for carbohydrate-deficient glycoprotein syndrome type 1b, a rare genetic disorder affecting how your body processes certain sugars. For urinary tract infections (UTIs), the evidence suggests it is possibly ineffective — so if you're taking it hoping it'll treat or prevent a UTI, the data we hold doesn't support that use.
How safe is it?
Well-documented data
D-mannose is generally well tolerated in the short term, though long-term safety data of high quality are limited. The most common side effects are bloating, diarrhea, and nausea.
Diarrhea risk goes up if you take a single dose larger than 200 mg per kilogram of body weight; at typical supplement doses like the 500 mg in this product, loose stools and bloating have been reported. Pregnancy safety hasn't been studied enough to know either way — talk with your doctor or pharmacist about whether it's right for you.
Breastfeeding safety is also not well studied, so caution is advised if you're nursing.
Meds to double-check
No known interactions
No interactions are documented in our data for D-mannose. Still, check your exact medications with the search tool on this page, and confirm with your doctor or pharmacist before starting.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. No medication interactions are currently documented, and safety information is well characterized.
This product is a straightforward source of D-mannose for people whose doctor recommends it for carbohydrate-deficient glycoprotein syndrome type 1b. If you're considering it for UTI prevention or treatment, the evidence doesn't back that use.
Before you start, especially if you're pregnant, breastfeeding, or taking any medications, talk it over with your doctor or pharmacist to make sure it fits your situation.
