HelloPharmacist Scorecard of Water Pill by Swanson

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Swanson Water Pill has 2 active ingredients: rutin and yellow sweet clover. Rutin is a plant compound traditionally used in supplements for circulation and capillary support.

Yellow sweet clover, also called sweet clover, has been used historically for similar purposes, though its effectiveness for any condition isn't firmly established in current evidence. The capsules also contain inactive ingredients — microcrystalline cellulose, gelatin, magnesium stearate, and silica — which are fillers and binding agents.

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.

Why this rating?
  • The label markets this product for: circulation and vascular health support.
  • We looked for evidence on: Varicose veins, Chronic venous insufficiency (CVI), Hemorrhoids, Bruises, Postoperative swelling, edema — and 2 related terms.
  • The closest evidence on file: Sweet Clover is rated "Insufficient Reliable Evidence To Rate" for Chronic venous insufficiency (CVI) (Natural Medicines).
  • Also on file: Sweet Clover is rated "Insufficient Reliable Evidence To Rate" for Hemorrhoids, Bruises, Postoperative swelling.
  • Also on file: Rutin is rated "Insufficient Reliable Evidence To Rate" for Hemorrhoids, Lymphedema, Varicose veins.

The evidence doesn't yet support either ingredient for the conditions it's been studied for. Rutin has insufficient reliable evidence to rate for aging skin, autism spectrum disorder, inflammatory bowel disease, diabetes, exercise-induced respiratory infections, and hemorrhoids.

Yellow sweet clover shows insufficient reliable evidence to rate for chronic venous insufficiency, diabetic neuropathy, hemorrhoids, and postoperative pain. If you're considering this product for a specific condition, there's no established proof it works for that use.

The evidence, ingredient by ingredient Rutin Sweet Clover

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Rutin is generally well tolerated when used short-term in food and supplements, though long-term safety data are limited. It may cause headache, flushing, or rash in some people.

Yellow sweet clover is generally well tolerated in small amounts, but its coumarin content affects bleeding and liver function, so caution is warranted. Large amounts of sweet clover can cause liver injury in susceptible people and, rarely, bleeding problems.

Headache and, at high doses, stupor have been reported. For pregnancy, rutin is likely safe, but sweet clover has insufficient safety data — talk with your doctor before using during pregnancy.

Safety while breastfeeding is unknown for both ingredients, so it's best to avoid supplement doses unless advised otherwise by your healthcare provider.

Each ingredient & the kinds of drugs it affects

For each ingredient in Water Pill with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Yellow Sweet Clover2 drug types · 480 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, fresh sweet clover might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Fresh sweet clover contains coumarinic acids, which are converted to free coumarins during drying. Dicoumarol, which has anticoagulant activity, also has been found in some sweet clover preparations and can be formed if fresh sweet clover is allowed to spoil.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use of sweet clover with hepatoxic drugs might increase the risk of hepatotoxicity.
Orally, large amounts of sweet clover can cause transient liver injury in susceptible individuals, possibly due to coumarin content. In one case report, a patient with multiple sclerosis developed jaundiced palms and a slight elevation in serum alanine aminotransferase (ALT) after taking sweet clover containing coumarin 10 mg daily for 3 years. Two weeks after starting therapy with subcutaneous interferon (IFN)-beta 1b, aspartate transaminase (AST) and ALT levels increased to 7 and 17 times the upper limit of normal, respectively. Levels normalized after discontinuation of both products. Subsequent use of IFN-beta 1a alone, without sweet clover, resulted in only a very slight increase in AST.

Theoretically, taking rutin with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that rutin has hypoglycemic effects.
