Rosehips Extract

Also known as: Rosehip, Rose hip, Rosehip extract, Rosa canina

Overview

Rosehips are the fruit of rose plants, particularly *Rosa canina*, and have been traditionally used for their medicinal properties. They are rich in vitamins A and C, flavonoids, and other antioxidants. Rosehip extract is primarily used for reducing inflammation, improving symptoms of osteoarthritis, and potentially aiding in blood glucose management. Research maturity is moderate, with several randomized controlled trials (RCTs) and meta-analyses available, particularly for osteoarthritis. The quality of available evidence is generally good for osteoarthritis studies, but variable for other applications. Rosehip powder and extracts are available in various forms, including capsules, powders, and teas.

Benefits

Rosehip powder has been shown to reduce pain and improve symptoms in osteoarthritis patients. A meta-analysis indicated that patients were twice as likely to respond to rosehip compared to placebo, with an effect size of 0.37 (95% CI: 0.13–0.60). Rosehip extract has also demonstrated significant reductions in fasting plasma glucose and HbA1c levels, comparable to metformin in some studies, suggesting potential benefits for individuals with type 2 diabetes. Some studies suggest reductions in body weight and fat area, though these findings are less consistent. Benefits in osteoarthritis have been observed within 3 months, while blood glucose improvements have been noted within 12 weeks.

How it works

Rosehip extract's anti-inflammatory and antioxidant effects are thought to contribute to its benefits in osteoarthritis and potentially in glucose metabolism. It may interact with inflammatory pathways and insulin sensitivity mechanisms. While the exact molecular targets are not well-defined, it likely involves modulation of inflammatory mediators and antioxidant pathways. The bioavailability of rosehip compounds varies, but they are generally absorbed and utilized by the body.

Side effects

Rosehip extract is generally considered safe, with few reported side effects. Gastrointestinal upset is a possible side effect. Allergic reactions or interactions with medications are rare but possible. Potential interactions with blood thinners or diabetes medications may occur due to its effects on blood glucose. Caution is advised for individuals with allergies to rose family plants. Pregnant or breastfeeding women should consult healthcare providers before use. While rare, it's important to monitor for any adverse reactions when starting rosehip supplementation.

Dosage

For osteoarthritis, doses around 5 g/day of rosehip powder have been effective. For blood glucose management, 450 mg/day of rosehip extract has shown benefits. Doses up to 5 g/day for osteoarthritis have been used without significant adverse effects, but the maximum safe dose is not well-established. Consistent daily intake is recommended for chronic conditions. Powder or extract forms are commonly used, and bioavailability may be enhanced with food intake. It is advisable to start with a lower dose and gradually increase it to assess tolerance.

FAQs

Is rosehip extract safe to take with other medications?

Rosehip extract is generally safe, but it should be used under medical supervision if combined with other medications, especially blood thinners or diabetes medications, due to potential interactions.

Can rosehip extract cause allergic reactions?

Allergic reactions to rosehip extract are rare but possible. Individuals with allergies to rose family plants should exercise caution and monitor for any signs of an allergic reaction.

How long does it take to see results from rosehip extract?

Improvements in osteoarthritis symptoms and blood glucose levels may be observed within weeks to months of consistent daily dosing. Individual results may vary.

Is rosehip extract a cure for diabetes or osteoarthritis?

Rosehip extract is not a cure for diabetes or osteoarthritis but may be a useful adjunctive treatment to help manage symptoms and improve overall health.

What is the best way to take rosehip extract?

Consistent daily dosing is recommended, and powder or extract forms are commonly used. Bioavailability may be enhanced with food intake. Follow the dosage guidelines provided by a healthcare professional or the product label.
