Organic Muscadine Grape And Seed Extract
Also known as: Muscadine grape seed extract, Muscadine grape polyphenols, Vitis rotundifolia seed extract
Overview
Muscadine grape seed extract is derived from the seeds of *Vitis rotundifolia*, a grape species native to the southeastern United States. This dietary supplement is highly valued for its rich content of polyphenols, particularly proanthocyanidins, which contribute to its potent antioxidant properties. Primarily, it is used for its potential benefits in supporting cardiovascular health and exhibiting anti-inflammatory effects. While promising, research on Muscadine grape seed extract is less extensive than on other grape seed extracts, with most evidence coming from in vitro and animal studies. Further human clinical trials are needed to fully understand and confirm its efficacy and applications.
Benefits
Muscadine grape seed extract is primarily recognized for its antioxidant and anti-inflammatory properties, largely attributed to its high polyphenol content. Some studies suggest it may contribute to cardiovascular health by reducing oxidative stress and inflammation. There is also preliminary evidence from in vitro and animal studies indicating potential anti-cancer effects, specifically inhibiting the proliferation of certain cancer cells, though human data is limited. Additionally, some research points to potential benefits in wound healing and cognitive health, but these areas require more robust investigation. The strength of evidence varies, with promising results from basic science but a need for more human clinical trials to establish clinical significance and effect sizes.
How it works
The primary mechanism of action for Muscadine grape seed extract involves its rich polyphenol content, especially proanthocyanidins. These compounds act as potent antioxidants, neutralizing free radicals and reducing oxidative stress within the body. By mitigating oxidative damage, they can help reduce inflammation and protect cellular integrity. The extract is believed to interact with various body systems, including the cardiovascular, immune, and nervous systems, by modulating inflammatory pathways and cell signaling. While specific molecular targets are not fully defined for Muscadine grape seed extract, its polyphenols are thought to influence enzymes involved in inflammation and oxidative stress. The bioavailability of these polyphenols can vary but is generally considered moderate.
Side effects
Muscadine grape seed extract is generally considered safe when used appropriately, though comprehensive data on long-term use is still emerging. Common side effects, occurring in more than 5% of users, may include gastrointestinal symptoms such as stomach ache, nausea, and diarrhea. Uncommon side effects (1-5%) can involve general weakness and other non-specific symptoms. Rare side effects are not well documented. A significant concern is its potential interaction with anticoagulant medications, such as warfarin, due to its own potential anticoagulant effects, which could increase the risk of bleeding. Therefore, individuals with bleeding disorders or those on anticoagulant therapy should exercise caution. It is contraindicated during pregnancy due to a lack of sufficient safety data.
Dosage
Specific dosage guidelines for Muscadine grape seed extract are not well established, as research is still evolving. However, based on general grape seed extract recommendations, typical doses range from 50 to 100 mg per day. The minimum effective dose and optimal dosage ranges for Muscadine specifically are not clearly defined. There is no established maximum safe dose, and it is advised not to exceed typical supplement doses without professional guidance. No specific timing recommendations are available for administration. It is available in various forms like capsules, tablets, or liquid, with no particular form recommended over others. Absorption and bioavailability may be influenced by other dietary components, but no specific cofactors are required.
