HelloPharmacist Scorecard of Vitamin C 1,000 mg by up&up
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
Low disclosure
This product has 4 active ingredients. Vitamin C is the main one at 1,000 mg per tablet — it's the essential nutrient your body uses for immune function, collagen formation, and wound healing.
Acerola is a tropical fruit that naturally contains vitamin C. Rose Hips (from the seed pods of rose plants) and Lemon Bioflavonoid Complex are supporting ingredients; bioflavonoids are plant compounds often paired with vitamin C.
The remaining ingredients are inactive fillers and binders that hold the tablet together.
Does it work?
Moderate evidence
Vitamin C is effective for preventing and treating vitamin C deficiency. It's possibly effective for anemia of chronic disease, atrial fibrillation, cataracts, and respiratory infections triggered by exercise.
Acerola is possibly effective for vitamin C deficiency, but evidence is insufficient to say whether it helps with the common cold, atherosclerosis, or diarrhea. For Lemon Bioflavonoid Complex, the evidence we hold is insufficient — we cannot say whether it helps with hay fever, anxiety, respiratory infections, high blood pressure, or kidney stones.
How safe is it?
Well-documented data
Vitamin C is generally well tolerated at normal dietary and supplement doses, but very high doses can cause side effects. At doses above 2,000 mg daily, you may experience abdominal cramps, heartburn, nausea, diarrhea, or headache — the most common issues are osmotic diarrhea and gastrointestinal upset.
Rare serious effects at very high doses include kidney stones (especially if you're prone to them) and, with intravenous infusions, acute kidney damage. Acerola is generally safe at food amounts but should be used cautiously as a concentrated supplement.
There's one case report of an allergic reaction (rash and breathing difficulty) in a person with multiple food allergies. Lemon in food amounts is well tolerated; gastrointestinal upset including heartburn can occur with concentrated lemon juice.
During pregnancy, normal dietary amounts of vitamin C are fine, but the facts advise against high-dose supplements unless your doctor directs otherwise. For acerola and lemon, there isn't enough data on file to know whether concentrated supplements are safe in pregnancy — talk with your doctor or pharmacist.
Meds to double-check
Moderate interaction found
Check with your pharmacist before taking this product if you use estrogens (birth control or hormone therapy) — vitamin C may increase their levels. Chemotherapy drugs (especially alkylating agents and antitumor antibiotics), warfarin (blood thinner), levothyroxine (thyroid hormone), indinavir (HIV), fluphenazine (antipsychotic), and itraconazole (antifungal) are also worth confirming.
If you take aluminum supplements or antacids, ask your pharmacist too.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is for anyone wanting to supplement their vitamin C intake, especially those with deficiency. If you take birth control pills, hormone replacement therapy, warfarin, levothyroxine, HIV medications, antipsychotics, chemotherapy drugs, or an antifungal like itraconazole, check with your pharmacist before starting — this product can change how those medications work.
Also let your pharmacist know if you take aluminum-containing antacids or have a history of kidney stones.

Vitamin C 1,000 mg by up&up Drug Interactions
HelloPharmacist Interaction Report
up&up Vitamin C 1,000 mg contains four active ingredients, and the product does interact with medications.
Vitamin C itself carries the most serious documented interactions — they're all Moderate severity. The biggest concern is estrogens (birth control pills and hormone replacement therapy): vitamin C can raise estrogen blood levels by up to 55%, which may increase side effects.
Vitamin C also theoretically may reduce how well certain chemotherapy drugs work, specifically alkylating agents and antitumor antibiotics that rely on generating free radicals to kill cancer cells.
Read the full breakdown — every affected drug type, severity by severity
Other Moderate interactions with Vitamin C include warfarin (a blood thinner), where high doses may reduce its effectiveness and thin your blood less than intended; levothyroxine (thyroid hormone), where vitamin C can increase absorption and change your thyroid levels; indinavir (an HIV drug), where it may modestly lower drug levels; fluphenazine (an antipsychotic), where it might decrease drug levels; and aluminum-containing products, where vitamin C increases how much aluminum your body absorbs.
Acerola, another active ingredient, shares some of vitamin C's concerns (it contains vitamin C) but at Minor severity — mainly chemotherapy drugs, estrogens, and warfarin. It may also interact slightly with aspirin and aluminum products, though acerola's vitamin C content is probably too low to cause real problems in practice.
We could not check Rose Hips for interactions — we hold no data for it. Lemon Bioflavonoid Complex carries one Minor interaction: it may increase itraconazole (an antifungal) levels if you take the tablet form with lemon-containing beverages.
Altogether, these interactions span 208 individual medications. Run your exact prescriptions and any aluminum supplements through the checker on this page before starting.

For each ingredient in Vitamin C 1,000 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Rose Hips
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.
Vitamin C
Alkylating Agents
Theoretically, antioxidant effects of vitamin C might reduce the effectiveness of alkylating agents.
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. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.
Aluminum
Vitamin C can increase the amount of aluminum absorbed from aluminum compounds.
Research in animals and humans shows that vitamin C increases aluminum absorption, theoretically by chelating aluminum and keeping it in solution where it is available for absorption. In people with normal renal function, urinary excretion of aluminum will likely increase, making aluminum retention and toxicity unlikely. Patients with renal failure who take aluminum-containing compounds such as phosphate binders should avoid vitamin C supplements in doses above the recommended dietary allowances.
Antitumor Antibiotics
Theoretically, the antioxidant effects of vitamin C might reduce the effectiveness of antitumor antibiotics.
The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs which generate free radicals, such as doxorubicin. 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. More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on chemotherapy.
Estrogens
Vitamin C might increase blood levels of estrogens.
Increases in plasma estrogen levels of up to 55% occur 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. Increases in plasma estrogen levels may occur when patients who are deficient in vitamin C take supplements. Monitor these patients for estrogen-related side effects.
Fluphenazine (Prolixin)
Theoretically, vitamin C might decrease levels of fluphenazine.
In one patient there was a clinically significant decrease in fluphenazine levels when vitamin C (500 mg twice daily) was started. The mechanism is not known, and there is no further data to confirm this interaction.
Indinavir (Crixivan)
Vitamin C can modestly reduce indinavir levels.
One pharmacokinetic study shows that taking vitamin C 1 gram orally once daily along with indinavir 800 mg orally three times daily reduces the area under the concentration-time curve of indinavir by 14%. The mechanism of this interaction is unknown, but it is unlikely to be clinically significant in most patients. The effect of higher doses of vitamin C on indinavir levels is unknown.
Levothyroxine (Synthroid, Others)
Vitamin C can increase levothyroxine absorption.
Two clinical studies in adults with poorly controlled hypothyroidism show that swallowing levothyroxine with a glass of water containing vitamin C 500-1000 mg in solution reduces thyroid stimulating hormone (TSH) levels and increases thyroxine (T4) levels when compared with taking levothyroxine alone. This suggests that vitamin C increases the oral absorption of levothyroxine, possibly due to a reduction in pH.
Warfarin (Coumadin)
High-dose vitamin C might reduce the levels and effectiveness of warfarin.
Vitamin C in high doses may cause diarrhea and possibly reduce warfarin absorption. There are reports of two people who took up to 16 grams daily of vitamin C and had a reduction in prothrombin time. Lower doses of 5-10 grams daily can also reduce warfarin absorption. In many cases, this does not seem to be clinically significant. However, a case of warfarin resistance has been reported for a patient who took vitamin C 500 mg twice daily. Cessation of vitamin C supplementation resulted in a rapid increase in international normalized ratio (INR). Tell patients taking warfarin to avoid taking vitamin C in excessively high doses (greater than 10 grams daily). Lower doses may be safe, but the anticoagulation activity of warfarin should be monitored. Patients who are stabilized on warfarin while taking vitamin C should avoid adjusting vitamin C dosage to prevent the possibility of warfarin resistance.
Acetaminophen (Tylenol, Others)
High-dose vitamin C might slightly prolong the clearance of acetaminophen.
A small pharmacokinetic study in healthy volunteers shows that taking high-dose vitamin C (3 grams) 1.5 hours after taking acetaminophen 1 gram slightly increases the apparent half-life of acetaminophen from around 2.3 hours to 3.1 hours. Ascorbic acid competitively inhibits sulfate conjugation of acetaminophen. However, to compensate, elimination of acetaminophen glucuronide and unconjugated acetaminophen increases. This effect is not likely to be clinically significant.
Aspirin
Acidification of the urine by vitamin C might increase aspirin levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase 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, suggesting this interaction is not clinically significant.
Choline Magnesium Trisalicylate (Trilisate)
Acidification of the urine by vitamin C might increase choline magnesium trisalicylate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase 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, suggesting this interaction probably is not clinically significant.
Niacin
Vitamin C might decrease the beneficial effects of niacin on high-density lipoprotein (HDL) cholesterol levels.
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease. It is not known whether this adverse effect is due to a single antioxidant such as vitamin C, or to the combination. It also is not known whether it will occur in other patient populations.
Salsalate (Disalcid)
Acidification of the urine by vitamin C might increase salsalate levels.
It has been suggested that acidification of the urine by vitamin C could increase reabsorption of salicylates by the renal tubules, and increase plasma salicylate levels. However, short-term use of up to 6 grams/day vitamin C does not seem to affect urinary pH or salicylate excretion, suggesting this interaction probably is not clinically significant.
Acerola
Alkylating Agents
Theoretically, the antioxidant effects of acerola might reduce the effectiveness of alkylating agents.
Acerola contains vitamin C, an antioxidant. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as alkylating agents. In contrast, other researchers theorize that antioxidants might make alkylating chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells. More evidence is needed to determine what effect, if any, antioxidants such as vitamin C have on chemotherapy.
Antitumor Antibiotics

More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.
Aluminum
Theoretically, concomitant use of acerola with aluminum salts might increase the amount of aluminum absorbed.
Acerola contains vitamin C. It is thought that vitamin C chelates aluminum, keeping it in solution and available for absorption. In people with normal renal function, urinary excretion of aluminum likely increases, making aluminum retention and toxicity unlikely. However, patients with renal failure who take aluminum-containing compounds, such as phosphate binders, should avoid acerola in doses that provide more vitamin C than the recommended dietary allowances.
Aspirin
Theoretically, acerola might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Acerola 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 acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and aspirin is unlikely.
Estrogens
Theoretically, concomitant use of acerola with estrogens might increase estrogenic effects.
Acerola contains vitamin C. Increases in plasma estrogen levels of up to 55% have occurred 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.

The vitamin C content of acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and warfarin is unlikely.
Lemon Bioflavonoid Complex
Itraconazole (Sporanox)
Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage.
