Summary of Rose Hip

Primary information, health benefits, side effects, usage, and other important details

Rose hip is a term used to refer to the extracts of rose plant fruit (of the Rosagenus), but it almost always refers specifically to Rosa canina, commonly known as the dog rose.

The fruits, and occasionally seeds, of dog rose are either ground up into a powder or made into tea, then supplemented to treat rheumatic diseases like osteoarthritis and rheumatoid arthritis. It improves joint health by reducing pain and stiffness.

Preliminary evidence also suggests rose hip may provide benefits to people with diabetes, as well as high blood pressure and cholesterol. It’s hypothesized that rose hip may have an anti-obesity effect, but this claim needs to be confirmed through research.

Rose hip alleviates joint pain through its immunosuppressive effects. The immune system can contribute to rheumatic diseases. An inflammatory cytokine called Interleukin 1-Beta (IL-1β) causes cartilage cells to produce proteins that digest and break down join tissue. In moderation, this process encourages cell turnover, but in excess, this process contributes to long-term joint tissue degradation, which is what causes joint problems. While rose hip doesn’t reduce IL-1β levels in the blood, it interferes with its ability to activate catabolic proteins.

Rose hip is also able to reduce chemotaxis, which is the transportation of immune cells into tissue. This serves as both an anti-inflammatory and immunosuppressive mechanism.

How to Take

Recommended dosage, active amounts, other details

The standard dose for rose hip is 5-10g a day, divided into two doses.

Rose hip powder is usually the preferred form of the supplement.

Rose hip should be taken with meals.

Doses as high as 40g have been used in studies. Aside from some intestinal distress, taking this much rose hip is not harmful.

Human Effect Matrix

Unlocked for Examine members

The Human Effect Matrix summarizes human studies to tell you what effects Rose Hip has on your body, how much evidence there is, and how strong these effects are.

Full details are available to Examine members.
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
grade-b Minor Very High See all 3 studies
There appears to be benefit to osteoarthritis symptoms with supplementation of rose hip relative to placebo, with benefits more apparent over longer periods of supplementation.
grade-c Minor Very High See 2 studies
A mild (3.7%) decrease in systolic blood pressure has been noted in obese persons given supplementation of rose hip.
grade-c Minor Very High See 2 studies
A mild reduction in LDL cholesterol levels seen in obese persons with rose hip supplementation explains the reduction in total cholesterol, as HDL-C appears to be unaffected.
grade-c Minor Moderate See all 4 studies
Pain is reduced alongside improvements in osteoarthritic and rheumatoid arthritis, and at least one study (cohort) noted benefits in persons without these diseases yet with high labour jobs. No studies in athletes to assess the analgesic properties yet.
grade-c Minor Very High See 2 studies
There appears to be mild benefits to joint symptoms in rheumatoid arthritis when rose hip is supplemented over the course of months, and these benefits may be seen at low (5g) dosages. Short term supplementation has not shown much benefit.
grade-c Minor Moderate See all 4 studies
A decrease in total cholesterol has been noted to a mild degree in obese persons, although a study in rheumatic patients without any abnormalities in cholesterol metabolism failed to find such an effect.
grade-c Minor - See 2 studies
Two human trials have found mixed results. One study in obese humans failed to find evidence for weight loss, whereas one study in overweight humans found some effect.
grade-c - - See study
No significant modifications in adiponectin concentrations when rose hip supplementation is given to humans.
grade-c - Very High See 2 studies
Both fasting and postprandial glucose in persons given prolonged rose hip supplementation is not affected relative to placebo.
grade-c - Moderate See all 5 studies
Preliminary studies showed marked reductions in C-reactive protein concentrations in healthy persons, although more recently conducted blinded studies have failed to replicate such a large decrease.
grade-c - Very High See 2 studies
No significant alteration of HDL-C concentrations has been noted with limited evidence investigating rose hip supplementation.
grade-c - - See study
No significant influence of rose hip on HbA1c concentrations in the blood of non-diabetic yet obese persons relative to placebo
grade-c - - See study
No significant influence on circulating (basal) insulin has been noted with rosehip supplementation.
grade-c - - See study
No significant influence on insulin sensitivity has been noted in obese humans relative to placebo.
grade-c - Very High See all 3 studies
No significant influence on the liver enzymes of otherwise healthy persons subject to rose hip supplementation
grade-c - - See study
At this point in time, there is no evidence to suggest modifications in the circulating levels of TNF-α relative to control.
grade-c - Very High See 2 studies
No significant influence of rose hip on triglyceride concentrations has been noted.
grade-d Notable - See study
A fairly notable effect was found in one study on overweight people.
grade-d Minor Very High See 2 studies
Chemotaxis of immune cells appears to be reduced with oral ingestion of rose hip supplements. This antiinflammatory/immunosuppressive mechanism is thought to underlie in part the benefits of rose hip against arthritic symptoms
grade-d Minor - See study
Creatinine, a biomarker of kidney damage and muscle damage, has been noted to be reduced with rose hip supplementation in one preliminary trial
grade-d Minor - See study
One study found 3 g of oral rose hip powder improved cheek skin elasticity over 8 weeks.
grade-d Minor - See study
3 g of oral rose hip powder over 8 weeks increased the moisture content of the skin of the forehead.
grade-d Minor - See study
3 g of oral rose hip powder decreased the depth of crow's feet wrinkles.
grade-d - - See study
Limited evidence has failed to find any significant changes in antioxidant enzyme profiles in the red blood cells of those given rose hip extract

  • As rose hip reduces chemotaxis, the antiinflammatory effects may also be seen as immunosuppressive. Prudency should be taken in persons with compromised immune systems, as no evidence has cleared rose hip for being medicinally benign in these persons
