Prune Fruit Extract
Also known as: Prune, Dried Plum, Prunus domestica
Overview
Prune fruit extract, sourced from dried plums of the Prunus domestica tree, is a dietary supplement recognized for its high fiber content, sorbitol, and polyphenolic compounds. These characteristics make prunes particularly beneficial for promoting gastrointestinal health, with established uses primarily for constipation relief. The extract is produced from natural sources and is available in various forms such as whole prunes and juice. Research indicates moderate effectiveness in improving stool frequency and consistency, positioning prunes as a valuable addition to dietary regimens aimed at enhancing digestive wellness.
Benefits
Prune fruit extract has demonstrated several evidence-based benefits, most notably in relieving constipation. A key study demonstrated that consuming 100 g of prunes daily increased bowel movement frequency from 2.8 to 3.5 times per week. Furthermore, prunes may aid in weight management, as indicated by a meta-analysis showcasing significant reductions in body weight among participants. These benefits are particularly prominent for individuals experiencing constipation and those with weight management goals. While the effect size for improving stool frequency is significant, clinical relevance may vary based on individual health conditions.
How it works
Prunes function by increasing dietary fiber intake, which enhances gut motility and promotes water absorption, aiding bowel movements. The presence of sorbitol, a natural sugar alcohol, contributes to osmotic effects in the intestines, encouraging stool passage. Although specific molecular targets are not identified, the overall interaction with gastrointestinal physiology is well-documented, providing a clear mechanism for the observed laxative effects.
Side effects
Prune fruit extract is generally regarded as safe; however, some common side effects, occurring in over 5% of users, include gastrointestinal discomfort, bloating, and gas, often due to increased fiber intake. Less frequently reported adverse effects (1-5%) may include allergic reactions or intolerances. Rare side effects (<1%) are not commonly noted. Interactions with medications impacting gut motility or absorption should be considered, and individuals with severe gastrointestinal disorders or plum allergies are cautioned to consult healthcare providers before use. Pregnant or breastfeeding women should also seek medical advice prior to starting supplementation with prunes.
Dosage
The minimum effective dose of prune fruit extract is around 50-100 grams daily, with 100 grams being optimal for constipation relief. Although the exact maximum safe dose is not defined, excessive intake may lead to increased gastrointestinal side effects. It is recommended to consume prunes with meals to minimize adverse effects. Both whole prunes and prune juice can be effective formats, but individuals should be aware that the fiber content is less absorbed, yet remains functional within the gut.
