I'm looking to enhance our range of wellness products focused on cognitive health. We know that walnuts are exceptional for promoting improved focus, memory recall, and overall psychological efficiency. Their unique nutritional profile, especially the significant levels of omega-3 fatty acids, sets them apart from other nuts, making them an ideal choice for consumers seeking to boost their mental well-being. In light of this, we're interested in sourcing high-quality walnuts that can be integrated into our offerings. We believe that incorporating walnuts into our product line will not only cater to health-conscious individuals but also capitalize on the growing demand for brain-boosting foods. Please provide details on your available walnut varieties and any relevant certifications or quality assurances you can offer. Looking forward to your prompt response!
