HelloPharmacist Scorecard of Extra Strength Rose Hips 4:1 Extract Powder by TerraVita Premium Collection
Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.
What’s inside
Full disclosure
This product contains one active ingredient: rose hip extract powder in a 4:1 concentration, which means four parts of the plant material are condensed into one part extract. Rose hips are the fruit of the rose plant and contain vitamin C, antioxidants, and other compounds.
There are no inactive ingredients listed.
Does it work?
Moderate evidence
Rose hip is possibly effective for postoperative pain (pain after surgery) and for osteoarthritis. The evidence for its effect on high cholesterol levels (hyperlipidemia) is insufficient to rate.
If you're considering it for one of these uses, it's worth discussing with your doctor whether the evidence matches your situation.
How safe is it?
Well-documented data
Rose hip from the species used in most studies is generally well tolerated as a food. The most common side effects from the supplement form are flatulence and loose stools.
Rarely, people have reported vertigo and headache. Because this is a concentrated extract rather than a food amount, it carries less studied safety data than whole rose hips—talk with your doctor before using it if you're concerned about your individual health profile.
High doses of vitamin C (which rose hip contains) can cause osmotic diarrhea and gastrointestinal upset, and the full safety profile of rose hip from all plant species hasn't been thoroughly evaluated.
Meds to double-check
Moderate interaction found
Check with your doctor or pharmacist before taking this product if you use estrogens (birth control or hormone replacement), blood thinners or antiplatelet drugs, lithium, chemotherapy drugs, aluminum-containing compounds, or aspirin or warfarin. The interactions span several medication types and range from Moderate to Minor severity.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Rose hip extract is possibly effective for postoperative pain and osteoarthritis, and it's generally well tolerated as a food. However, this concentrated supplement form has less safety research than whole rose hips, and it interacts with several medication types—most notably estrogens, blood thinners, and lithium.
Before starting it, check with your doctor or pharmacist, especially if you take any prescription medications.

HelloPharmacist Interaction Report
TerraVita Premium Collection's Extra Strength Rose Hips 4:1 Extract Powder interacts with several medication types, most seriously through its vitamin C content and a compound called rugosin E.
The most serious concern is with estrogens (birth control pills and hormone replacement therapy), where vitamin C in rose hip may raise estrogen blood levels by up to 55% in some cases.
Read the full breakdown — every affected drug type, severity by severity
Rose hip may also affect blood thinners and antiplatelet drugs by potentially reducing their effectiveness, though this hasn't been confirmed in humans. It could theoretically increase lithium levels due to diuretic effects, possibly requiring a dose adjustment.
Additionally, the antioxidants in rose hip might interfere with certain chemotherapy drugs (alkylating agents and antitumor antibiotics), though there's also a theory they could reduce side effects—this contradiction means you'll want to talk it through with your oncologist. Rose hip may increase aluminum absorption from aluminum-containing compounds, and its vitamin C could theoretically affect aspirin and warfarin, though the amounts are probably too low to matter clinically.
Altogether, these interactions span 213 individual medications. Use the search tool below to check your exact prescriptions before starting this product.

Rose Hips Extract, Powder
Alkylating Agents
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa. In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity. More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.
Aluminum
Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown. Administer rose hip two hours before or four hours after antacids.
Anticoagulant/Antiplatelet Drugs
Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation. This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.
Antitumor Antibiotics
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics. In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.
Estrogens
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.
Lithium
Theoretically, rose hip might increase blood levels of lithium.
Rose hip is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, rose hip might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
Aspirin
Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels. However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.
Warfarin (Coumadin)
Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption. This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time. Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant. The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.
