AI Comparison Analysis
Solgar L-Theanine 150mg Free Form vs Bulk Glycine Powder
Solgar L-Theanine 150mg Free Form: 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.
Scores: effectiveness: 6/10, ingredient_quality: 7/10, value_for_money: 4/10, side_effects: 10/10, certifications: 9/10, overall: 7/10
Bulk Glycine Powder: Bulk's Glycine Powder offers the same pure amino acid as NOW Foods in a larger 500g quantity at a lower UK price. The sensible 3g serving size matches the clinical dose, unlike NOW's 1g label serving. Quality is comparable — pure glycine is pure glycine regardless of brand. The main advantage is price; the main disadvantage is the pouch packaging versus a rigid tub.
