How to take it
- Clinically studied dosage: 900 mg per day of standardised spearmint extract (containing approximately 14.5% rosmarinic acid and 24% total polyphenols)
- Neumentix specific: The Neumentix branded extract was used in the clinical trials at 900 mg/day
- Timing: Take once daily with a meal. Morning dosing is common but not required - the compound is non-stimulant
- Onset: Some studies show acute cognitive improvements within hours. Full benefits develop over 30-90 days of consistent use
- Not from spearmint tea: Regular spearmint tea contains far lower polyphenol concentrations than the standardised extract used in clinical trials
Watch out for
- Excellent safety profile: Spearmint has GRAS (Generally Recognised as Safe) status. Clinical trials report no significant adverse effects at 900 mg/day
- Anti-androgenic effect: Spearmint may reduce testosterone levels in women (studied for hirsutism treatment). Men should be aware of this potential effect,...
- Mild GI effects: Occasional mild digestive discomfort reported. Peppermint and spearmint may relax the lower oesophageal sphincter, potentially worsening...
- Drug interactions: Rosmarinic acid may interact with iron absorption. Minimal known drug interactions at standard doses
- Pregnancy: Culinary amounts of spearmint are safe. High-dose supplement safety in pregnancy has not been specifically studied
The science, if you're curious.
- Rosmarinic acid mildly inhibits acetylcholinesterase and butyrylcholinesterase, increasing acetylcholine availability for improved attention and memory
- Inhibits COX-2 and 5-lipoxygenase pathways, reducing prostaglandin and leukotriene-mediated neuroinflammation
- Activates the Nrf2 pathway, upregulating endogenous antioxidant enzymes to protect neurons from oxidative damage
- Rosmarinic acid has been shown to increase BDNF expression, supporting hippocampal neuroplasticity and memory consolidation
Where to find it
- Neumentix: Kemin Industries' branded spearmint extract, standardised for rosmarinic acid content - the exact formulation used in clinical trials
- Generic spearmint extract: Standardised spearmint extracts available from various supplement manufacturers (verify polyphenol/rosmarinic acid content)
- Capsules: Typically available in 450 mg capsules (take 2 per day to reach the 900 mg clinical dosage)
