Indian Jujube (Ber) (Ziziphus mauritiana) is a fruit used for exceptionally rich in vitamin c, supporting antioxidant defense and immune function. NutriDex grades the human evidence as Preliminary. Indian jujube (ber) is a small tropical fruit notable for an exceptionally high and variable vitamin C content (often 60–165 mg/100g), well above most common fruits. Direct human trials on Z. mauritiana itself are essentially absent; the clinical evidence base comes from the closely related Z. jujuba, where small RCTs and two recent meta-analyses suggest jujube consumption can modestly reduce BMI, triglycerides, total cholesterol and LDL, with fasting-glucose benefits concentrated in type-2-diabetic subgroups. These trials are few (4–7 studies, under 500 participants total), short (1–12 weeks), heterogeneous in dose and preparation, and largely conducted in Iran, so confidence is low and effect sizes should be read cautiously. Phytochemical work on Z. mauritiana documents abundant flavonoids and phenolic acids with antioxidant and anti-inflammatory activity, but these are mostly in vitro and animal data. Sedative/anxiolytic claims trace to seed jujubosides studied in the distinct species Z. spinosa, not the edible ber fruit, and should not be extrapolated. Overall, jujube is a nutritious, vitamin-C-dense fruit with biologically plausible but preliminary metabolic benefits awaiting larger, rigorous trials.
Purported Benefits
✓Exceptionally rich in vitamin C, supporting antioxidant defense and immune function
✓May modestly lower LDL, triglycerides and total cholesterol (evidence mostly from the related species Ziziphus jujuba)
✓May reduce fasting blood glucose and BMI, with glucose benefits concentrated in type-2-diabetic adults
✓High polyphenol and flavonoid content with measurable antioxidant/anti-inflammatory activity in animal models
✓Low energy density and high water content suit weight-conscious diets
Dosing & Compounds
Typical Dose
A typical serving is about 3 fresh fruits (~100 g), providing roughly 69 mg vitamin C. Lipid- and glucose-lowering trials (on the related Z. jujuba) used 5–30 g/day of dried fruit powder or 15 g/day of extract.
Active Compounds
Vitamin C (L-ascorbic acid) — unusually high, roughly 55–165 mg/100g across cultivarsFlavonols & flavones (quercetin, rutin, kaempferol, myricetin, apigenin)Phenolic acids (chlorogenic, gallic, caffeic, ferulic, p-coumaric, ellagic acids)Dammarane saponins / jujubosides A & B (concentrated in seed, not the edible flesh)Triterpenic acids (betulinic, oleanolic, ursolic acid)Cyclopeptide alkaloids (mauritine-type)Carotenoids and provitamin A precursorsSoluble and insoluble dietary fiber (including pectins)Minerals: potassium, calcium, phosphorus, manganese
Safety & Cautions
⚠
Generally recognized as safe as a food. Concentrated dried-fruit powders or extracts that lower blood glucose and lipids could theoretically add to the effects of antidiabetic or lipid-lowering drugs—monitor if combining. Ziziphus seed preparations have sedative activity and may potentiate CNS depressants/sedatives; the edible fruit flesh carries little of this. The hard stone (pit) is a choking hazard, especially for children. Pollen and fruit can rarely trigger allergy. Safety of high-dose extracts in pregnancy and lactation is not established. Educational only — always check with your doctor or pharmacist before combining Indian Jujube (Ber) with any medicine.
