Juniper Berry Fruit Extract

Also known as: Juniper berry, Juniper fruit, *Juniperus communis*

Overview

Juniper berries are the seed cones of the *Juniperus communis* tree, an evergreen shrub prevalent worldwide, particularly in North America, Europe, and Asia. Historically, they have been used for culinary seasoning, gin production, and traditional medicine. Rich in volatile oils, flavonoids, and antioxidants, juniper berries possess potential anti-inflammatory, antimicrobial, and antidiabetic properties. Current research primarily consists of in vitro and animal studies, with limited human clinical evidence suggesting moderate to low research quality.

Benefits

Juniper berries exhibit several potential health benefits, although evidence varies in strength. Key findings include: 1) **Antioxidant and Anti-Inflammatory Effects**: In vitro studies show increased antioxidant enzyme activity. 2) **Antidiabetic Properties**: Animal studies indicate reductions in blood glucose and improvements in lipid profiles. 3) **Heart Health**: Some evidence suggests improved cholesterol levels. Additional benefits may include antimicrobial and anticancer effects, yet human data remain sparse, necessitating further research for conclusive findings.

How it works

The beneficial effects of juniper berries arise from their active components, particularly volatile oils and monoterpenes. These compounds activate various antioxidant enzymes and show anti-inflammatory properties. Additionally, lignans found in juniper may promote proteasome activity, offering potential benefits in cellular health and reducing lipofuscin accumulation in skin cells. However, these mechanisms require further verification through human studies.

Side effects

The safety profile of juniper berries is uncertain due to a lack of comprehensive human trials. Common gastrointestinal discomfort may occur, while rare instances of kidney irritation are suggested but not well substantiated. Potential drug interactions with diuretics and diabetes medications raise concerns for individuals on these treatments. Children, pregnant individuals, and those with kidney impairment should avoid juniper berry supplements due to these risks. Caution is warranted, especially when considering dosage and pre-existing conditions.

Dosage

While the specific minimum effective dose isn't well defined, traditional practices suggest 2-10 g/day of whole or powdered berries. Typical dosages for extracts range from 2-3 mL of fluid extract or 2-3 g of infusion taken three times daily. The effective upper limit is unclear, but caution with high doses is recommended due to potential interactions and irritant effects. A variety of forms are available, including whole berries, essential oils, and extracts, each requiring careful consideration in terms of intended use.
