Wild rose hip fruits are particularly rich in vitamin C, containing 426 mg per 100 g[4] or 0.4% by weight (w/w). RP-HPLC assays of fresh rose hips and several commercially available products revealed a wide range of L-ascorbic acid (vitamin C) content, ranging from 0.03 to 1.3%.[5]

Rose hips contain the carotenoids beta-carotene, lutein, zeaxanthin, and lycopene.[6][7] A meta-analysis of human studies examining the potential for rose hip extracts to reduce arthritis pain concluded there was a small effect requiring further analysis of safety and efficacy in clinical trials.[8] Use of rose hips is not considered an effective treatment for knee osteoarthritis.[9]
