Acerola 17% Vitamin C
Acerola contains 17% natural vitamin C (ascorbic acid) plus bioflavonoids that enhance absorption and bioavailability. This combination supports immune function through enhanced neutrophil activity and provides antioxidant protection via free radical scavenging.

Origin & History
Acerola, also known as Barbados cherry, is native to South America and the Caribbean. The extract is standardized to 17% vitamin C, known for its immune-boosting properties.
Historical & Cultural Context
Acerola has been used in traditional medicine for centuries, valued for its high vitamin C content and health benefits.
Health Benefits
- Boosts immune function by enhancing white blood cell activity, reducing the risk of infections by up to 30%. - Rich in antioxidants, acerola protects cells from oxidative stress, promoting overall health. - Supports skin health by promoting collagen production, leading to firmer, more youthful skin. - May improve cardiovascular 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 by reducing oxidative stress in the brain, potentially lowering the risk of cognitive decline. - Contains anti-inflammatory properties that can help alleviate symptoms of chronic inflammatory conditions.
How It Works
Acerola's ascorbic acid stimulates neutrophil chemotaxis and enhances interferon production, while co-occurring anthocyanins and quercetin amplify antioxidant capacity. The vitamin C promotes collagen synthesis 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.
Scientific Research
Research highlights acerola's high vitamin C content, which supports immune function and skin health. Further studies are needed to explore additional benefits.
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. - Contains vitamin A and dietary fiber. - Low in calories and free from fat.
Preparation & Dosage

Safety & 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.
