AI Comparison Analysis
Optimum Nutrition BCAA 1000 Caps vs Bulk Glycine Powder
Optimum Nutrition BCAA 1000 Caps: Optimum Nutrition BCAA 1000 is the market leader in capsule BCAAs, offering a convenient and well-dosed product from a trusted brand. The 2:1:1 ratio is the standard supported by most research. However, contemporary sports nutrition science increasingly questions the value of isolated BCAAs when dietary protein is adequate. The Informed Sport certification adds genuine value for competitive athletes. Best reserved for specific scenarios like fasted training rather than general daily supplementation.

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.
