Mulberry Fruit Extract

Mulberry fruit extract is a concentrate of the dark berries of the mulberry tree, rich in anthocyanins and other plant pigments that act as antioxidants in the body. People mostly look at it for blood sugar control, and the evidence is limited: in diabetic mice and rats, the extract improved glucose control and insulin sensitivity. Nearly all of this work was in animals or cell studies, so it says little yet about how the extract affects people.

General

General: outcomes studied for Mulberry Fruit Extract
GradeOutcomeEffectSizeStudiesPeopleStudies list
Blood Sugar Control

Multiple animal studies demonstrate consistent antidiabetic effects. In diabetic db/db mice, mulberry fruit extract improved glycemic control and insulin sensitivity via AMPK activation (PMID:27441957). Fruit polysaccharides reduced fasting blood glucose and improved glucose tolerance in HFD/STZ-induced diabetic rats (PMID:28163112). A polyphenol-enhanced extract also showed antidiabetic effects in rodent models (PMID:23936259).

Inflammation

In vitro studies using LPS-stimulated RAW 264.7 macrophages consistently show anti-inflammatory effects. Mulberry fruit extract suppressed pro-inflammatory cytokines and mediators including nitric oxide and prostaglandin E2 (PMID:30978947, PMID:33572374). Bioactive phytochemicals from the fruit also demonstrated anti-inflammatory activity in macrophage models (PMID:34360887).

Immune Function

A pectic polysaccharide from mulberry fruit demonstrated immunomodulating activity including macrophage activation and cytokine production (PMID:24120956). Water-soluble polysaccharide fractions showed immunoenhancement properties (PMID:29777809). An aqueous fruit extract also exhibited immunostimulatory effects (PMID:34441742). All evidence is preclinical.

Liver Protection

A polysaccharide from mulberry fruit protected hepatocytes against palmitic acid-induced lipotoxicity by activating the Nrf2/ARE signaling pathway in cell models (PMID:31537067). In rats, mulberry fruit aqueous extract accelerated acute ethanol metabolism and promoted antioxidant enzyme systems (PMID:29767238). Evidence is preliminary.

Antioxidant Status

Multiple in vitro studies confirm strong free radical scavenging and antioxidant activity of mulberry fruit extracts, attributed to anthocyanins and phenolic compounds (PMID:22408465, PMID:19241543). In vivo studies in rats showed enhanced antioxidant enzyme systems (PMID:29767238). Flavonoid fractions demonstrated both in vitro and in vivo antioxidant activity (PMID:27076749).

Cognitive Function

In rodent models, mulberry fruit extract enhanced memory via induction of nerve growth factor (PMID:23182412). Two studies in Alzheimer's disease mouse models showed the extract alleviated cognitive impairment by promoting amyloid-β clearance and inhibiting neuroinflammation (PMID:32488469), and reduced amyloid-β oligomer-induced cognitive disturbance and oxidative stress (PMID:34387016).

Body Weight Management

A pectic polysaccharide from mulberry fruit showed anti-obesity effects in an animal model (PMID:27112865). In 3T3-L1 adipocytes, mulberry fruit extract ameliorated adipogenesis via AMPK activation and microRNA modulation (PMID:32191574). Evidence is limited to one animal and one in vitro study.
