Sun An-ti, an authority on immunology, affirms the concept behind nutritional immunology. But, even more, he hopes that a company as large as E. Excel can provide more basic experimental evidence. "If there are no clinical tests, at least there must be reports about tests on animals. This would be more responsible to the public."
台灣的免疫學專家孫安迪肯定營養免疫學的理念，卻更期待以丞燕公司這樣的規模，應該多拿出原則性的實驗數據，「如果沒有臨床檢驗，至少也有動物實驗報告，這樣比較能對大眾負責。」
