HelloPharmacist Scorecard of Acerola Extract (25% Vitamin C) by BulkSupplements.com

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.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: acerola extract, standardized to 25% vitamin C. Acerola is a tropical fruit rich in ascorbic acid (vitamin C), an antioxidant your body uses for immune function, collagen formation, and protecting cells from damage.

The product contains no other inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Acerola's overall clinical evidence instead.

Moderate

Some clinical evidence supports Acerola for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Vitamin C deficiency — rated "Possibly Effective" (Natural Medicines).

The data we hold shows acerola is possibly effective for vitamin C deficiency — the condition it's most commonly used for. For other uses like the common cold, atherosclerosis, and diarrhea, the evidence isn't established enough to rate.

If you're looking to prevent or treat a cold or support heart health, we don't yet have solid data that acerola delivers those benefits.

The evidence, ingredient by ingredient Acerola

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Acerola from food sources and standard supplement doses are generally well tolerated. That said, the safety notes advise caution: food amounts are fine, but concentrated supplements haven't been studied thoroughly.

At high doses — more than 2,000 mg of vitamin C daily — osmotic diarrhea and stomach upset can occur. There's one case report of someone who had an allergic reaction (rash, shortness of breath, rapid heartbeat) after drinking acerola juice, linked to a latex cross-reactivity; this is rare and occurred in someone with a history of latex sensitivity.

A child who ate large amounts of acerola fruit daily for a week developed a bowel obstruction, so stick to label doses.

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Acerola.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; cancer treatments.
  • For scale: 128 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your pharmacist before taking acerola if you're on chemotherapy drugs (alkylating agents or antitumor antibiotics), hormonal birth control or hormone replacement therapy, high-dose aspirin, blood thinners like warfarin, or aluminum-based antacids. The vitamin C in acerola may theoretically reduce the effect of chemotherapy or boost estrogen levels, or interfere with how aspirin and warfarin are cleared from your body.

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.

Acerola is a straightforward vitamin C source, possibly effective for C deficiency. If you're on chemotherapy, hormones, or blood thinners, check with your pharmacist first — the antioxidant effects might interfere with how those work.

For everyone else, standard doses are generally well tolerated; just don't exceed label recommendations.

Acerola extract6 drug types · 128 drugs

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.

Likelihood Possible Evidence D
Antitumor Antibiotics

Theoretically, the antioxidant effects of acerola might reduce the effectiveness of antitumor antibiotics.
Acerola contains vitamin C, an antioxidant. 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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Unlikely Evidence B
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.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, acerola might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Acerola 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 acerola is typically about 2000 mg per 100 grams. Thus, a clinically significant interaction between acerola and warfarin is unlikely.

Acerola Extract (25% Vitamin C) by BulkSupplements.com: Common Questions

Does Acerola Extract (25% Vitamin C) by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Acerola Extract (25% Vitamin C) has a known interaction with 128 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Acerola Extract (25% Vitamin C) contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Does acerola actually prevent colds?
The evidence isn't established well enough yet for us to say. While acerola is high in vitamin C, studies on whether it truly prevents or shortens colds don't give us solid answers.
What are the most common side effects?
At standard doses, acerola is generally well tolerated. High doses over 2,000 mg of vitamin C daily can cause osmotic diarrhea and stomach upset. A rare allergic reaction (rash, breathing trouble, fast heartbeat) has been reported in someone with latex sensitivity.
Can I take this while pregnant or breastfeeding?
The product facts we hold don't include pregnancy or breastfeeding safety data for acerola. Talk with your doctor or pharmacist about whether it's right for you during these times.
Is this safe if I have kidney problems?
The facts we hold don't address kidney function. Since acerola is a concentrated source of vitamin C, which is filtered through the kidneys, talk to your pharmacist if you have kidney disease before taking it.
Can I take too much acerola?
Yes. More than 2,000 mg of vitamin C daily can cause diarrhea and digestive upset. One child who ate large amounts of acerola fruit daily developed a bowel blockage, so stick to the dose on the label.
