I'm looking to source health food excipients for my products. Specifically, I'm interested in excipients that can enhance bioavailability and stability while ensuring they meet dietary standards. It's important that the ingredients are suitable for various health-focused formulations. Could you provide details on the types of excipients you offer, including their source, functionality, and any relevant certifications? Also, if you have sample products or data sheets available, that would be helpful for evaluating options. Looking forward to your response!
