Sage
Also known as: Salvia officinalis, common sage, garden sage, sage essential oil, sage aroma
Effective Dosage
No established dose
What the Science Says
Sage (Salvia officinalis) is a culinary herb that has been studied for potential cognitive effects. One clinical trial found that inhaling sage aroma improved memory and executive function in healthy adults compared to no aroma, and also increased alertness and reduced fatigue. A cosmetic safety review assessed sage-derived ingredients for topical use. However, the provided research does not include clinical trials on oral sage supplementation, so dose and timeframe for any internal benefit are unknown.
What It Doesn't Do
No evidence from these studies that taking a sage supplement pill improves memory or cognition. The cognitive effects found were from smelling sage aroma, not swallowing it. No evidence it treats any disease. Don't assume cosmetic-grade sage extracts are safe or effective to ingest. No data supporting weight loss, hormone balance, or immune benefits.
Evidence-Based Benefits
Sage has shown promise in improving cognitive function and has anti-inflammatory properties. Several systematic reviews and clinical trials support its potential benefits in enhancing memory and reducing inflammation.

Absorption & Bioavailability
Unknown — the only clinical evidence in provided studies is for aroma inhalation, not oral absorption. No pharmacokinetic data provided.
Red Flags to Watch For
- All cognitive benefit data comes from aroma inhalation studies, not oral supplementation — supplement pills may not replicate these effects
- No oral dosing data in any provided study — products listing a 'clinically effective dose' are not supported by this evidence base
- Cosmetic safety review covers topical use only; safety of ingesting sage extracts at supplement doses is not addressed in provided papers
- 668 registered supplement products exist despite very limited clinical trial evidence for oral use
