When sourcing L-Carnitine in bulk, buyers often focus only on price. After 12 years supplying sports nutrition and pharmaceutical clients, we have learned the real differentiators are purity consistency, documentation, and lead time.
Why Purity Specs Matter More Than Unit Price
Most buyers ask for 98%+ assay. What they rarely check is the batch-to-batch variance. A supplier quoting a low price with ±3% variance will cost you more in failed QC than one holding ±0.5%.
Documentation Buyers Actually Need
Beyond the standard Certificate of Analysis, serious buyers request Halal, Kosher, and USP verification. We maintain all three on file for every batch.
