Gandaria (Bouea macrophylla) is a fruit used for antioxidant (polyphenol-rich, in vitro). NutriDex grades the human evidence as Preliminary. Gandaria (marian plum, maprang, kundang) is a small Southeast Asian mango-relative eaten ripe as a sweet-tart fruit. Compositionally it is a watery, low-calorie fruit (~49 kcal/100 g by Atwater calculation from its macros) providing modest vitamin C (~20 mg/100 g in the Malaysian reference database, though other sources report higher), beta-carotene, potassium and a notable load of hydrolysable tannins and gallic/ellagic acids that give it strong in-vitro antioxidant activity. Laboratory and isolated-compound studies show the seed and leaf extracts inhibit α-glucosidase (a mechanism relevant to blood-sugar control), kill several bacteria and fungi, and are cytotoxic to cultured cancer cells, while oral extract in UVB-exposed hairless mice reduced wrinkling and preserved collagen. Crucially, essentially all health evidence is in vitro or in animals: there are no human clinical trials of gandaria fruit or its extracts for any outcome. Reported antioxidant and enzyme-inhibition potencies come from concentrated extracts, not the amounts you would get from eating the fruit. A 28-day rodent study of a fruit-extract yoghurt found no toxicity up to 2000 mg/kg, supporting general food safety. Overall the human evidence is preliminary, and benefits beyond ordinary fruit nutrition should be considered unproven.
Generally safe as a food; rodent toxicity studies of fruit-extract yoghurt showed no adverse effects (acute LD50 >2000 mg/kg; 28-day dosing up to 1000 mg/kg/day). As a mango-family (Anacardiaceae) fruit, the peel/sap can cause contact dermatitis or allergic reactions in people sensitive to mango/urushiol. Unripe fruit is very sour and astringent. Concentrated seed/leaf extracts are not characterized for human use, and their α-glucosidase inhibition could theoretically add to glucose-lowering medication effects—no human interaction data exist. Educational only — always check with your doctor or pharmacist before combining Gandaria with any medicine.
Gandaria is most often taken for Antioxidant (polyphenol-rich, in vitro), Vitamin C source, Beta-carotene (provitamin A), α-glucosidase inhibition (antidiabetic, preclinical). Tangy tropical plum-mango rich in gallotannins.

What is the typical dose of Gandaria?
Culinary fruit; ~100 g (a small handful of 3–5 fruits) as a typical serving. No established therapeutic dose.
Is Gandaria safe? Any cautions or side effects?
Generally safe as a food; rodent toxicity studies of fruit-extract yoghurt showed no adverse effects (acute LD50 >2000 mg/kg; 28-day dosing up to 1000 mg/kg/day). As a mango-family (Anacardiaceae) fruit, the peel/sap can cause contact dermatitis or allergic reactions in people sensitive to mango/urushiol. Unripe fruit is very sour and astringent.
