Solgar L-Theanine 150mg Free Form
by Solgar
Premium free-form L-theanine in Solgar's signature vegetable capsules, providing 150mg per serving. Free-form amino acids are not bound to other compounds, potentially allowing faster absorption. Solgar's pharmaceutical-grade manufacturing standards and amber glass packaging offer additional quality assurance. A premium alternative for those who trust the Solgar brand.
AI Review Summary
Solgar's L-Theanine offers the brand's characteristic quality assurance but at a significant price premium over equally effective alternatives. The 150mg dose is below the 200mg clinical standard, and it lacks the Suntheanine patent used by NOW Foods. Wide UK availability in Boots and Holland & Barrett is convenient for high-street shoppers. Kosher and Halal certifications add value for those communities. Hard to recommend over NOW Foods on a pure efficacy-per-pound basis.
