Rosehips Fruit Extract
Also known as: Rose hips, Rosehaws, Dog Rose, *Rosa canina*
Overview
Rose hips are the pseudo-fruits of the *Rosa canina* plant, recognized for their high content of bioactive compounds such as polyphenols, flavonoids, carotenoids, and vitamins. Traditionally, they have been used for their anti-inflammatory, antioxidant, and anti-oxidative properties, being explored for therapeutic applications in conditions like osteoarthritis, rheumatoid arthritis, and inflammatory bowel disease. Key characteristics include a rich profile of phenolic compounds, including quercetin and galactolipid GOPO, which play crucial roles in their health benefits. The research surrounding rose hips, particularly standardized extracts, has progressed significantly, encompassing numerous randomized controlled trials (RCTs), meta-analyses, and systematic reviews, although some studies exhibit limitations such as small participant numbers and potential conflicts of interest.
Benefits
Rose hips exhibit various evidence-based benefits with quantified outcomes. A meta-analysis of three RCTs with 287 osteoarthritis patients showed significant pain reduction associated with rose hip powder, with patients being twice as likely to respond positively compared to placebo, demonstrating a moderate clinical effect size of 0.37. Additional benefits include improved functional outcomes, reduced medication use, and enhanced wellbeing and sleep quality. Secondary effects include antioxidant and anti-inflammatory properties highlighted in both in vitro and in vivo studies, as well as potential wound healing benefits from rose hip oil, though more clinical evidence is required in that area. The pain reduction effects are particularly favorable for osteoarthritis patients, where significant outcomes were observed within 3-4 months of treatment.
How it works
The therapeutic effects of rose hips are primarily attributed to their antioxidant and anti-inflammatory properties. These are mediated by the bioactive compounds, specifically flavonoids and carotenoids, which reduce inflammation and oxidative stress. Galactolipid GOPO is notable for its anti-inflammatory effects, targeting molecular pathways related to inflammation and oxidative damage. Additionally, these compounds enhance the absorption of key nutrients, such as Vitamin C, thus contributing to overall health benefits.
Side effects
Rose hip powder is generally considered safe and well-tolerated, with a high safety profile. Common side effects occurring in more than 5% of users include mild gastrointestinal discomfort and acid regurgitation. Uncommon side effects, reported by 1-5% of individuals, may include frequent urination, diarrhea, constipation, and mild urticaria. Rare side effects have not been consistently documented. There is limited information regarding drug interactions, though caution is advised when used alongside other anti-inflammatory or antioxidant agents. Individuals with allergies to plants in the rose family should take care, and pregnant or breastfeeding women are recommended to consult healthcare providers due to a lack of research in these populations.
Dosage
The minimum effective dosage for rose hip powder, particularly for managing osteoarthritis, is typically around 2.5-5 grams per day. Optimal dosages range from 2.5 to 5 grams daily, ideally taken in divided doses to ensure efficacy. While there is no established maximum safe dose, clinical trials have used up to 5 grams daily without significant adverse effects. Timing of administration is flexible, although daily consistency is encouraged. Standardized rose hip powder has been most studied and is recommended for therapeutic applications. The presence of flavonoids in rose hips can enhance the absorption of other nutrients, further supporting its potential health benefits.
