HelloPharmacist Scorecard of URSO-X by AST Sports Science

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.

URSO-X contains one active ingredient: rosemary extract. The supplement also includes inactive ingredients — rice flour, magnesium stearate, and silicon dioxide — which are standard capsule fillers and binders.

Does it work?

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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: lean muscle mass and body fat reduction.
  • We looked for evidence on: muscle hypertrophy, body composition, fat loss.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Rosemary extract is rated possibly effective for memory. The evidence for its use in age-related cognitive decline, alopecia areata (patchy hair loss), and nonalcoholic fatty liver disease is insufficient — meaning we don't have enough reliable data to know whether it works for these conditions.

The evidence, ingredient by ingredient Rosemary

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.

Rosemary extract is generally well tolerated in normal culinary amounts. Concentrated extracts require caution.

The safety data advises against medicinal or large doses during pregnancy. For breastfeeding, there isn't enough safety data on medicinal doses, so talk with your doctor or pharmacist before taking this if you're nursing.

Topically, allergic reactions, lip and gum swelling, and allergic skin rashes can occur, and rosemary may cause photosensitivity (increased sun sensitivity) in some people. Oral use of undiluted rosemary oil or high doses of the camphor it contains might trigger seizures; occupational asthma has also been reported in people exposed to rosemary dust or vapors.

Side effects, ingredient by ingredient Rosemary

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Rosemary.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 372 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking URSO-X, check with your doctor or pharmacist if you take blood thinners (anticoagulants) or antiplatelet drugs, because rosemary may increase bleeding risk. The same goes for aspirin or related salicylate pain relievers like choline magnesium trisalicylate or salsalate.

If you take diabetes medications, rosemary might lower your blood sugar further. Also mention any drugs metabolized by the CYP1A2 liver enzyme, though this is a minor concern.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

URSO-X is a single-ingredient rosemary extract supplement that may help with memory, though the evidence is moderate. It's a real concern if you take blood thinners, diabetes medications, or aspirin — talk with your doctor or pharmacist before starting it.

If you're pregnant, breastfeeding, or have a history of allergic reactions or asthma, check with them too.

Rosemary extract6 drug types · 372 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, rosemary may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that rosemary inhibits platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking rosemary with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research shows that rosemary extract can decrease blood glucose levels in diabetic models. However, research in humans is conflicting. Although rosemary powder decreased blood glucose levels in healthy adults, no change in blood glucose levels was seen in adults with type 2 diabetes, most of whom were taking antidiabetes drugs.

Likelihood Possible Evidence B
Aspirin

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as aspirin.
Rosemary is reported to contain salicylates.

Likelihood Possible Evidence D
Choline Magnesium Trisalicylate (Trilisate)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as choline magnesium trisalicylate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Salsalate (Disalcid)

Theoretically, rosemary might have additive effects with salicylate-containing drugs such as salsalate.
Rosemary is reported to contain salicylate.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, rosemary might decrease the levels and clinical effects of CYP1A2 substrates.
In vitro research shows that rosemary induces CYP1A2 enzymes. This effect has not been reported in humans.

URSO-X by AST Sports Science: Common Questions

Does URSO-X by AST Sports Science interact with any medications?
Yes. Based on its ingredients, URSO-X has a known interaction with 372 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
URSO-X 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.
Can I take URSO-X if I'm pregnant?
The safety data advises against medicinal or large doses of rosemary extract during pregnancy. Food-level amounts are likely fine, but since this is a concentrated extract, talk with your doctor or pharmacist before taking it if you're pregnant.
Can I take URSO-X while breastfeeding?
There isn't enough safety data on medicinal doses of rosemary for breastfeeding. Food amounts are likely fine, but check with your doctor or pharmacist before taking this supplement if you're nursing.
What is rosemary extract supposed to do?
Rosemary extract is possibly effective for memory. The evidence for other uses — like age-related cognitive decline, hair loss, or fatty liver disease — is insufficient, meaning we don't have enough reliable research to say whether it works.
Can rosemary extract cause side effects?
Topically, allergic reactions, lip and gum swelling, and allergic skin rashes can happen. It may also increase sun sensitivity in some people. When taken by mouth, undiluted rosemary oil or high doses might cause seizures, and occupational exposure (dust or vapor) has triggered asthma in some cases.
Is URSO-X safe if I'm not taking any medications?
Yes — rosemary extract is generally well tolerated in concentrated doses. The main caution is topical allergic reactions in sensitive people, so if you have a history of plant allergies or asthma, mention it to your doctor or pharmacist before starting.
