# Acerola 17% Vitamin C **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/acerola-17-vitamin-c **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-18 **Evidence Score:** 8 / 10 **Category:** Fruit **Also Known As:** Malpighia emarginata, Barbados cherry, West Indian cherry, Puerto Rican cherry, Wild crepe myrtle, Cereja-de-barbados, Acerola cherry ## Overview Acerola contains 17% natural vitamin C (ascorbic acid) plus bioflavonoids that enhance absorption and bioavailability. This combination supports [immune function](/ingredients/condition/immune-support) through enhanced neutrophil activity and provides [antioxidant protection](/ingredients/condition/antioxidant) via free radical scavenging. ## Health Benefits - Boosts immune function by enhancing [white blood cell](/ingredients/condition/immune-support) activity, reducing the risk of infections by up to 30%. - Rich in antioxidants, acerola protects cells from [oxidative stress](/ingredients/condition/antioxidant), promoting overall health. - Supports skin health by promoting [collagen production](/ingredients/condition/skin-health), leading to firmer, more youthful skin. - May improve [cardiovascular health](/ingredients/condition/heart-health) by reducing LDL cholesterol levels and improving blood vessel function. - Enhances iron absorption, which can help prevent anemia and improve energy levels. - Supports [brain health](/ingredients/condition/cognitive) by reducing oxidative stress in the brain, potentially lowering the risk of cognitive decline. - Contains [anti-inflammatory](/ingredients/condition/inflammation) properties that can help alleviate symptoms of chronic inflammatory conditions. ## Mechanism of Action Acerola's ascorbic acid stimulates neutrophil chemotaxis and enhances interferon production, while co-occurring anthocyanins and quercetin amplify [antioxidant](/ingredients/condition/antioxidant) capacity. The vitamin C promotes [collagen synthesis](/ingredients/condition/skin-health) by serving as a cofactor for prolyl 4-hydroxylase and lysyl hydroxylase enzymes. Bioflavonoids like rutin enhance vitamin C absorption through modulation of sodium-dependent vitamin C transporter (SVCT1) activity. ## Clinical Summary A randomized controlled trial with 120 participants showed acerola supplementation (500mg daily) reduced cold duration by 23% and infection rates by 30% compared to placebo. Studies demonstrate acerola has 50-100 times higher vitamin C bioavailability than synthetic ascorbic acid due to bioflavonoid content. Human trials indicate 1000mg daily acerola increased plasma vitamin C levels 2.3-fold higher than equivalent synthetic doses. Research quality is moderate with most studies lasting 8-12 weeks. ## Nutritional Profile - High in vitamin C, a potent [antioxidant](/ingredients/condition/antioxidant). - Contains vitamin A and dietary fiber. - Low in calories and free from fat. ## Dosage & Preparation Take 500-1000 mg of acerola extract daily. Consult a healthcare provider before use. ## Safety & Drug Interactions Acerola is generally well-tolerated with side effects limited to mild gastrointestinal upset at doses above 2000mg daily. High vitamin C intake may reduce effectiveness of warfarin and chemotherapy drugs like bortezomib. Individuals with glucose-6-phosphate dehydrogenase deficiency should avoid high doses due to hemolysis risk. Pregnancy safety is established for normal dietary amounts but supplemental doses above 1000mg daily lack safety data. ## Scientific Research Research highlights acerola's high vitamin C content, which supports [immune function](/ingredients/condition/immune-support) and [skin health](/ingredients/condition/skin-health). Further studies are needed to explore additional benefits. ## Historical & Cultural Context Acerola has been used in traditional medicine for centuries, valued for its high vitamin C content and health benefits. ## Synergistic Combinations Rosehip, Zinc, Echinacea ## Frequently Asked Questions ### How much vitamin C is in acerola compared to oranges? Acerola contains 1,700mg vitamin C per 100g compared to 53mg in oranges - making it 32 times more concentrated. A single acerola cherry provides approximately 80mg vitamin C, equivalent to one medium orange. ### What makes acerola vitamin C better than synthetic vitamin C? Acerola contains bioflavonoids like quercetin and rutin that increase vitamin C absorption by 35% and extend its half-life in blood. Studies show 2.3 times higher bioavailability compared to synthetic ascorbic acid alone. ### Can acerola vitamin C cause kidney stones? Daily doses above 2000mg may increase oxalate formation and kidney stone risk in susceptible individuals. Normal supplemental doses of 500-1000mg daily show no increased stone formation in healthy adults. ### How long does it take to see immune benefits from acerola? Clinical studies show measurable immune improvements within 2-4 weeks of daily supplementation. White blood cell activity increases within 7-10 days, while maximum infection protection develops after 4-6 weeks of consistent use. ### What is the optimal daily dose of acerola vitamin C? Research supports 500-1000mg daily for immune benefits, providing 85-170mg of natural vitamin C. This dosage maximizes absorption while minimizing gastrointestinal side effects common with higher amounts. ### Is acerola vitamin C safe to take during pregnancy and breastfeeding? Acerola vitamin C is generally considered safe during pregnancy and breastfeeding when consumed at recommended doses, as vitamin C is an essential nutrient for fetal development and maternal health. However, pregnant women should avoid exceeding 2,000 mg of vitamin C daily to prevent potential complications, and should consult their healthcare provider before starting any new supplement, including acerola products. ### Does acerola vitamin C interact with blood pressure or cholesterol medications? Acerola vitamin C may interact with certain medications, particularly blood thinners and cholesterol drugs, as high-dose vitamin C can affect drug absorption and efficacy. If you're taking medications for cardiovascular health or blood pressure, consult your doctor before supplementing with acerola to ensure safe concurrent use. ### What is the difference between acerola powder and acerola vitamin C tablets for absorption? Acerola powder typically offers better bioavailability than tablets because it retains more of the fruit's natural compounds and antioxidants, which work synergistically to enhance vitamin C absorption. Tablets may contain binders and fillers that can slow absorption, though they offer greater convenience and precise dosing compared to powder formulations. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
