Muscadine Grape Fruit Pomace Extract
Also known as: Muscadine grape, Scuppernong grape, Vitis rotundifolia
Overview
Muscadine grape fruit pomace extract is derived from the pomace of Muscadine grapes, native to the southeastern United States. This extract is notable for its high content of polyphenols, including flavonoids and phenolic acids, which contribute to its strong antioxidant properties. It is primarily used as a dietary supplement for potential health benefits, including antioxidant effects, anticancer properties, and antimicrobial activities. Notably high in total phenolics, flavonoids, and anthocyanins, Muscadine grape pomace has attracted moderate research interest, although much of the evidence comes from in vitro and animal studies, with limited clinical trials in humans to date, indicating a need for further research.
Benefits
The primary evidence-based benefits of Muscadine grape extract include significant antioxidant activity, which aids in protecting cells from oxidative stress. Studies indicate its effectiveness against specific pathogens, showcasing antimicrobial effects against bacteria such as *Listeria monocytogenes* and *Staphylococcus aureus*. Some research also suggests potential anticancer effects, particularly against breast cancer cells. However, much of this evidence is derived from preclinical studies, with a significant gap in human clinical trials. Individuals looking for natural options to enhance antioxidant intake may find benefit, although the degree of efficacy in humans requires further investigation.
How it works
The antioxidant properties of Muscadine grape extract are primarily attributed to its rich polyphenol content, which scavenges free radicals and enhances the body’s antioxidant defense mechanisms. This process involves interaction with various cellular pathways linked to inflammation and cell proliferation. Through its antimicrobial properties, it may influence the immune and digestive systems, supporting overall health. Although the bioavailability of these polyphenols has not been extensively studied, it is generally understood that interactions with dietary fats could enhance absorption.
Side effects
Muscadine grape extract is generally considered safe when consumed in typical dietary amounts, with no severely documented side effects. However, potential gastrointestinal upset has been reported, similar to other polyphenol-rich supplements occurring in over 5% of users. Rare and undocumented side effects may include allergic reactions in sensitive populations. There is limited evidence concerning drug interactions, but caution is advised for individuals taking anticoagulants or diabetes medications owing to potential effects on antioxidants. While no specific contraindications are identified, safety is not established for use during pregnancy or breastfeeding, reinforcing the need for a healthcare consultation before use, particularly for elderly individuals or those with compromised health.
Dosage
The minimum effective dose of Muscadine grape extract is not officially established; it is typically consumed in amounts similar to other polyphenol supplements. Optimal dosage ranges remain undetermined and may differ based on individual health goals. Specific timing guidelines are lacking, but taking the extract with meals may mitigate gastrointestinal discomfort. Various formulations are available, such as capsules and powders, allowing for personal preference in consumption. It is crucial to note that while high doses lack a specific upper limit, caution is recommended in exceeding general consumption thresholds, as high dosages may pose risks.
