I'm interested in sourcing Urolithin A capsules for our private label brand. We're looking for a reliable supplier who can provide high-quality products that meet our specifications. Ideally, the capsules should contain standardized dosages and adhere to all relevant quality and safety standards. Could you please provide detailed information regarding your manufacturing processes, quality control measures, and any certifications you hold? Additionally, I'd like to know about your minimum order quantities, pricing, and lead times for delivery. It would be great if you could share some product samples or documentation to help us evaluate your offerings.
