What does Rose Hip Extract do?

Plant extract with antioxidant and anti-inflammatory properties, but most human evidence comes from multi-ingredient blends.

Is Rose Hip Extract safe?

All positive human trial data comes from a multi-ingredient product (Lady Prelox®) — you cannot attribute benefits to rose hip extract alone

Rose Hip Extract

Also known as: Rosa canina, rosehip, rose hip powder, rose hip shell powder, Rosvita®, RHPMJ, rosehip polyphenol

Effective Dosage

No established dose from provided studies

What the Science Says

Rose hip extract comes from the fruit of the rose plant (Rosa canina) and contains polyphenols, proanthocyanidins, and flavonoids that act as antioxidants. Lab studies show it can reduce reactive oxygen species produced by immune cells, and animal research suggests it may help with blood sugar regulation at the prediabetic stage. In human studies, it has only been tested as part of a multi-ingredient supplement blend (Lady Prelox®), making it impossible to isolate rose hip's specific contribution to the observed benefits in sexual function and vaginal health.

What It Doesn't Do

Can't credit rose hip alone for any human clinical results — every human study used it mixed with other active ingredients. No proven standalone benefit for joint pain, sexual function, or blood sugar in humans from the provided data. Don't assume animal or lab results translate directly to people. Not a proven diabetes treatment.

Evidence-Based Benefits

Rose hip extract contains polyphenolics (proanthocyanidins, flavonoids) that demonstrate antioxidant activity by inhibiting reactive oxygen species in vitro (PMID: 11933119). In animal models, a hot-water rose hip extract showed anti-prediabetic effects by improving glucose tolerance (PMID: 28182280). A pilot study in humans found rose hip shell powder may inhibit cytokine expression via lipophilic fractions, suggesting anti-inflammatory potential, though no significant improvement over a comparator powder was observed in pain outcomes (PMID: 25043856).

Weak Evidence

Effective at: No established dose from provided studies for standalone use; used as 50 mg in combination formula (PMID: 24051943); up to 20 g/day powder in pain study (PMID: 25043856)

Absorption & Bioavailability

Unknown — no pharmacokinetic or absorption data provided in the available studies. The extract is taken orally, but how well its active polyphenols are absorbed in humans has not been reported in the provided papers.

Red Flags to Watch For

All positive human trial data comes from a multi-ingredient product (Lady Prelox®) — you cannot attribute benefits to rose hip extract alone
The pain pilot study (up to 20 g/day) found no significant difference between rose hip shell powder and a comparator product, suggesting limited standalone efficacy for musculoskeletal pain
Blood sugar and anti-diabetic effects are based solely on animal (rat) data — no human trials on this claim in the provided studies
Safety data beyond 90 days is not established from the provided research; long-term human safety studies are lacking
Widely used in supplements (1,000+ registered products) despite very limited standalone clinical evidence
