HelloPharmacist Scorecard of Sage 400 mg by Signature Supplements

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.

Sage 400 mg is a single-ingredient supplement: one active ingredient, sage leaf extract, at 400 milligrams per capsule. The product also contains two inactive ingredients — cellulose and diatomaceous earth — which are fillers and capsule material.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Supports cognitive function and cooling herb.
  • We looked for evidence on: Cognitive function, Age-related cognitive decline, Menopausal symptoms, Mental fatigue, Focus, Mood.
  • The strongest evidence on file: Sage is rated "Possibly Effective" for Cognitive function (Natural Medicines).
  • Also on file: Sage is rated "Possibly Effective" for Menopausal symptoms.
  • Also on file: Sage is rated "Insufficient Reliable Evidence To Rate" for Age-related cognitive decline.

The evidence we hold shows sage is possibly effective for three uses: relieving menopausal symptoms, lowering cholesterol (high lipid levels), and supporting cognitive function. For postoperative pain (pain after surgery), the evidence leans toward possibly ineffective.

Keep in mind that 'possibly effective' means the research is promising but not yet conclusive — more studies are needed to be sure.

The evidence, ingredient by ingredient Sage

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.

Sage is generally well tolerated when used as a food or as tea for the short term. When taken as a concentrated medicinal extract — like the capsule form here — it should be used cautiously.

The most common side effects reported orally are abdominal pain, agitation, diarrhea, dizziness, nausea, and vomiting. Rarely, sage constituents (especially thujone) have been linked to seizures.

Topical use can cause burning, dermatitis, or pain; one trial participant developed an acneiform skin rash. Avoid medicinal or concentrated amounts during pregnancy because of thujone content; food amounts are likely fine.

During breastfeeding, avoid medicinal amounts — sage has traditionally been used to reduce milk supply, so check with your doctor or pharmacist before taking it.

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 — Sage.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: seizure medications; diabetes medications.
  • For scale: 1,297 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 Sage 400 mg, double-check with your pharmacist if you take CNS depressants (sedatives, sleep aids, some pain relievers), blood pressure medications, drugs metabolized by liver enzymes (CYP3A4, CYP2D6, CYP2C19, or CYP2C9), medications transported by P-glycoprotein, or hormone therapy including estrogen. These are areas where theoretical interactions have been identified in lab work.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Sage may be worth considering if you're interested in menopausal symptom relief, cholesterol support, or brain health, and your doctor approves. If you take any medication metabolized by your liver, use blood pressure drugs, take CNS depressants, or use hormone therapy, you need to check this with your pharmacist first.

Pregnant people and those breastfeeding should talk to their doctor before starting.

Sage14 drug types · 1,296 drugs

Anticholinergic Drugs

Theoretically, sage might decrease the clinical effects of anticholinergic drugs.
In vitro evidence suggests that common sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) can inhibit acetylcholinesterase and might increase acetylcholine levels.

Likelihood Possible Evidence D
Anticonvulsants

Theoretically, sage might interfere with the clinical effects of anticonvulsant drugs.
Some species of sage can cause convulsions when consumed in large quantities.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking sage with antidiabetes drugs might increase the risk of hypoglycemia.
In patients with polycystic ovary syndrome (PCOS) or inadequately controlled type 2 diabetes, common sage (Salvia officinalis) has demonstrated hypoglycemic activity. However, other clinical research in patients with inadequately controlled type 2 diabetes shows that common sage extract does not lower fasting blood glucose levels.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, sage might increase or decrease the effects of antihypertensive drugs.
Animal research suggests that common sage (Salvia officinalis) can cause prolonged blood pressure reduction. However, clinical research suggests that Spanish sage (Salvia lavandulaefolia) can increase blood pressure in some people with hypertension. Until more is known, use with caution.

Likelihood Possible Evidence D
Benzodiazepines

Theoretically, taking sage might increase the sedative and adverse effects of benzodiazepines.
In vitro evidence suggests that certain components of common sage (Salvia officinalis) can bind to benzodiazepine receptors. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, sage might have additive effects when used with cholinergic drugs.
In vitro evidence suggests that common sage (Salvia officinalis) and Spanish sage (Salvia lavandulaefolia) can inhibit acetylcholinesterase and might increase acetylcholine levels.

Likelihood Possible Evidence D
Cns Depressants

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, sage might decrease the levels and clinical effects of drugs metabolized by CYP2E1.
Animal research suggests that drinking common sage (Salvia officinalis) tea increases the expression of CYP2E1. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, sage might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro evidence suggests that aqueous extracts of sage can inhibit CYP3A4. So far, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, sage might interfere with hormone therapy.
In vitro evidence suggests that geraniol, a constituent of Spanish sage (Salvia lavandulaefolia), exerts estrogenic activity. The clinical significance of this effect is unclear.
