Caper Bush Extract

Also known as: Capparis spinosa, Caper Bush, Caper Plant

Overview

Capparis spinosa, commonly known as the caper bush, is a plant native to the Mediterranean region. It is valued for its buds, fruits, and leaves, all of which are rich in bioactive compounds such as flavonoids, phenolic acids, and glucosinolates. Traditionally, it has been used in both food and medicine due to its antioxidant, anti-inflammatory, and potential healing properties. Research interest in Capparis spinosa is growing, with studies exploring its pharmacological benefits. While some studies show promising results, more rigorous clinical trials are needed to confirm its efficacy. It is often consumed as pickled buds or extracts, leveraging its potential benefits for metabolic health and antioxidant status. However, it should not be considered a substitute for medical treatment, and consultation with healthcare professionals is advised before using it as a supplement.

Benefits

Caper bush extract has shown potential benefits in improving liver enzymes and lipid profiles, particularly in individuals with metabolic syndrome or type 2 diabetes. A systematic review and meta-analysis indicated significant reductions in ALT and improvements in HDL cholesterol levels with caper fruit supplementation. Furthermore, various studies have suggested antioxidant, anti-inflammatory, and potential antidiabetic properties. These effects are attributed to the bioactive compounds present in the plant, such as flavonoids and phenolic acids. While these findings are promising, the quality of available evidence is variable, and more rigorous clinical trials are needed to establish conclusive evidence and understand the time course of these benefits fully. The observed benefits typically occur over several weeks of supplementation.

How it works

Caper bush extract exerts its effects primarily through antioxidant and anti-inflammatory pathways. The bioactive compounds, such as phenolic compounds and flavonoids, target inflammatory mediators and oxidative stress pathways. It may interact with the digestive, cardiovascular, and hepatic systems, potentially influencing glucose and lipid metabolism. However, limited data is available on the bioavailability of these compounds, and they may undergo degradation during digestion. Further research is needed to fully elucidate the mechanisms of action and the specific molecular targets involved.

Side effects

Caper bush extract is generally considered safe when consumed in traditional culinary amounts, but comprehensive safety data is lacking. Common side effects are not well-documented, but potential gastrointestinal upset has been reported. Due to its bioactive compounds, there is a potential for interactions with antidiabetic or anticoagulant medications. It is contraindicated during pregnancy and breastfeeding due to insufficient safety data. Caution is advised in individuals with allergies to caper or related plants. More research is needed on the long-term use and interactions of caper bush extract to fully assess its safety profile.

Dosage

The minimum effective dose of caper bush extract has not been established, as it is often used in traditional culinary amounts. Some studies have used dosages of 100-300 mg/kg/day in animal models. The maximum safe dose is also not established. There are no specific timing recommendations for its consumption. It is often consumed as pickled buds or extracts. Bioavailability may be affected by digestion and the matrix type of the product. No required cofactors for its activity have been documented. Consult a healthcare provider for personalized advice on appropriate dosage.
