Rose Hip and Estradiol

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ESTROGENS

Why this applies to Estradiol

Estradiol falls under ESTROGENS — the group Rose Hip interacts with.

Theoretically, rose hip might increase blood levels of estrogens.
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the idea behind pairing rose hip with your estradiol. Rose hip is naturally high in vitamin C, and in a few older reports, vitamin C nudged estrogen blood levels up (by as much as 55% in some cases). The thinking is that vitamin C slows the breakdown of estrogen, so a bit more stays active in your body. If that happened, you might notice more estrogen-type effects, like breast tenderness, bloating, nausea, or spotting.

That said, this is theoretical and based on weak, anecdotal evidence. It seems to mainly matter in women who were low in vitamin C to begin with. Food amounts of rose hip are very unlikely to be an issue. Before starting a concentrated rose hip supplement, just run it by your pharmacist or doctor.

About Rose Hip

What is Rose Hip?

Rose Hip
  • Joint pain and osteoarthritis
  • Colds and flu
  • Source of vitamin C
  • Digestive complaints
  • Anti-inflammatory support

Rose hip is the vitamin C–rich fruit of the wild rose, used traditionally for colds and joint pain. A standardized rose hip powder has some research support for easing osteoarthritis symptoms, but evidence for most other uses is limited. It is generally well tolerated as a food, but talk with your pharmacist or doctor before using it as a supplement.
