Bone Health
To evaluate Naringin effects on bone loss in ovariectomized rats
Study Type
Animal study
Purpose
To evaluate Naringin effects on bone loss in ovariectomized rats
Dose
50-150 mg/kg Naringin
Participants
36 ovariectomized rats
Duration
12 weeks
Results
Naringin supplementation dose-dependently preserved bone mineral density, improved trabecular bone architecture, and reduced bone resorption markers. Bone formation markers elevated vs OVX controls.
How They Measured It
Bone mineral density (DXA), bone histomorphometry, osteocalcin, CTX
To evaluate Naringin supplementation in postmenopausal women with low bone density
Study Type
Randomised controlled trial
Purpose
To evaluate Naringin supplementation in postmenopausal women with low bone density
Dose
500 mg Naringin daily
Participants
90 postmenopausal women
Duration
12 months
Results
Naringin significantly reduced bone loss at lumbar spine (0.3% vs 1.4% in placebo) and suppressed CTX levels. No serious adverse events were observed.
How They Measured It
DXA scan at lumbar spine and hip, bone turnover markers
Metabolic Health
To investigate Naringin supplementation on insulin resistance and lipid profiles in obese subjects
Study Type
Randomised double-blind placebo-controlled trial
Purpose
To investigate Naringin supplementation on insulin resistance and lipid profiles in obese subjects
Dose
400 mg Naringin daily
Participants
75 obese adults with insulin resistance
Duration
12 weeks
Results
Naringin significantly improved insulin sensitivity (HOMA-IR −18%), reduced triglycerides and LDL, and increased HDL compared to placebo. Modest reduction in body fat percentage also observed.
How They Measured It
HOMA-IR, fasting glucose, lipid panel, body composition
To investigate anti-obesity mechanisms of Naringin in diet-induced obese mice
Study Type
Animal study
Purpose
To investigate anti-obesity mechanisms of Naringin in diet-induced obese mice
Dose
100-200 mg/kg Naringin
Participants
24 diet-induced obese mice
Duration
8 weeks
Results
Naringin significantly reduced body weight and fat accumulation, upregulated PPARα expression, enhanced fatty acid β-oxidation, and downregulated lipogenic gene expression in adipose tissue.
How They Measured It
Body weight, adipose tissue mass, gene expression of lipid metabolism regulators, fatty acid oxidation
Anti-inflammatory Activity
To evaluate Naringin on inflammatory markers in patients with rheumatoid arthritis
Study Type
Randomised controlled trial
Purpose
To evaluate Naringin on inflammatory markers in patients with rheumatoid arthritis
Dose
500 mg Naringin twice daily
Participants
80 adults with rheumatoid arthritis
Duration
16 weeks
Results
Naringin as adjunct significantly reduced DAS28 scores (−26%), CRP (−31%), TNF-α (−28%), and ESR compared to placebo. Joint swelling and tenderness also significantly reduced.
How They Measured It
DAS28 score, CRP, IL-1β, TNF-α, ESR
To elucidate anti-inflammatory signaling pathways of Naringin in macrophages
Study Type
In vitro study
Purpose
To elucidate anti-inflammatory signaling pathways of Naringin in macrophages
Dose
5-100 μM Naringin
Participants
RAW 264.7 macrophage cell line
Duration
24 hours
Results
Naringin inhibited LPS-induced NF-κB activation, suppressed MAPK phosphorylation, and reduced COX-2 and iNOS expression, leading to reduced prostaglandin E2 and nitric oxide production.
How They Measured It
NF-κB nuclear translocation, MAPK activation, COX-2/iNOS expression, prostaglandin E2
Neuroprotection
To evaluate neuroprotective effects of Naringin in an Alzheimer's disease mouse model
Study Type
Animal study
Purpose
To evaluate neuroprotective effects of Naringin in an Alzheimer's disease mouse model
Dose
25-100 mg/kg Naringin
Participants
30 APP/PS1 transgenic mice
Duration
10 weeks
Results
Naringin significantly improved spatial learning and memory, reduced amyloid plaque burden, decreased neuroinflammation, and inhibited acetylcholinesterase activity compared to vehicle controls.
How They Measured It
Morris water maze, β-amyloid plaque burden, neuroinflammation markers, cholinesterase activity
To summarize evidence for citrus flavonoids in neurodegenerative disease models
Study Type
Systematic review
Purpose
To summarize evidence for citrus flavonoids in neurodegenerative disease models
Dose
Various formulations reviewed
Participants
Review of 22 studies
Duration
Various
Results
Naringin and related flavonoids consistently demonstrate neuroprotective effects in cellular and animal models of AD and PD. Anti-neuroinflammatory and antioxidant mechanisms key. Human clinical trials are warranted.
How They Measured It
Systematic review of pre-clinical and clinical studies
To investigate Naringin protective effects against Parkinson's-like neurodegeneration
Study Type
Animal study
Purpose
To investigate Naringin protective effects against Parkinson's-like neurodegeneration
Dose
40-80 mg/kg Naringin
Participants
24 rats with MPTP-induced parkinsonism
Duration
4 weeks
Results
Naringin protected dopaminergic neurons, preserved motor function, maintained dopamine levels, and reduced oxidative stress in the substantia nigra of MPTP-treated rats.
How They Measured It
Behavioral tests (rotarod, open field), dopamine levels, tyrosine hydroxylase expression, oxidative stress
