現代人民的健康意識抬頭，預防醫學的觀念開始成形並普及，服用保健食品也似乎成為全民運動。但保健食品並非藥品，沒有法律或嚴格的監管制度或團體去監督資訊的正確性，民眾可能會受到模糊甚至是不正確的訊息影響，使自身利益或健康受害。如果能透過專業醫事人員的把關，更可以維護民眾食用保健食品的安全。因此本研究本研究從民眾的特徵，以感知風險為中介變數，查看民眾在保健食品上諮詢專業醫事人員的意圖。本研究列舉的消費者的特徵有民眾的資訊來源(如:內部的產品知識或外部的社會影響)、民眾本身的健康狀態和民眾對健康的動機。了解這些消費者特徵的影響力，期望能給予相關專業人員更多了解影響民眾諮詢的因素。
本研究透過網路發放問卷，共收回253份問卷，並用路徑分析得出以下結論。感知風險對於專業服務具有正向且高度之影響。健康行為會受到個人的態度和信念影響，產品知識和健康動機對於感知風險呈現正向之影響。社會影響和健康狀態對於感知風險呈現負向之影響，顯示正確且完整的健康訊息環境和自我身體健康狀態的審視很重要。
