英国采购需求：草本提取物、植物提取物、甜味剂、益智成分、蔬菜和果汁粉、精油

I'm interested in sourcing beef heart powder and would like to know your pricing details for this product. Additionally, I'm curious if you offer other organ powders as well. If so, please provide pricing information for those as well. Understanding your product range and pricing will help me determine how we can collaborate moving forward. I'm looking for quality options and competitive pricing, so any details on varieties, specs, and bulk purchasing would be greatly appreciated. Thank you!
