Grape Skin Extract And Activin
Also known as: Grape Skin Extract, Grape Skin Polyphenol Extract, Vitis vinifera Extract
Overview
Grape skin extract is derived from the skins of grapes, primarily *Vitis vinifera*, and is a rich source of polyphenolic compounds, particularly anthocyanins and flavonoids. It is primarily used for its antioxidant properties, aiming to combat oxidative stress and related conditions. The extract is available in various forms, including capsules and powders. While research supports its antioxidant effects, the clinical significance of these effects requires further investigation. The quality of available evidence is moderate, with studies focusing on its ability to modulate oxidative stress and inflammation. However, more research is needed to fully understand its efficacy and potential benefits.
Benefits
Grape skin extract's primary benefit is its antioxidant effect, attributed to its high content of anthocyanins. Some studies suggest potential cardiovascular benefits due to these antioxidant properties, but the evidence is mixed. It may be beneficial for individuals with conditions related to oxidative stress. However, the clinical significance of these effects is not well-established, and more research is needed to determine its efficacy. The time course for observing benefits from grape skin extract is not well-defined. Further studies are needed to quantify outcomes and establish clinical significance.
How it works
Grape skin extract primarily acts through antioxidant pathways, inhibiting oxidative stress by neutralizing free radicals. It interacts with the cardiovascular and immune systems by reducing oxidative damage. The polyphenols in grape skin extract target oxidative stress pathways at a molecular level. The bioavailability of these polyphenols can vary, but they are generally absorbed in the gut, contributing to their systemic effects. Further research is needed to fully elucidate the mechanisms of action and interactions with various body systems.
Side effects
Grape skin extract is generally considered safe, but high doses may cause gastrointestinal side effects such as discomfort or upset stomach. Specific uncommon or rare side effects are not well-documented. Potential interactions with medications are also not well-documented, necessitating caution when taken with other drugs. Pregnant or breastfeeding women should consult healthcare providers before using grape skin extract. While generally safe, more research is needed to fully understand its safety profile and potential adverse effects, especially at high doses or in specific populations.
Dosage
The minimum effective dose for grape skin extract is not well-established, but typical doses range from 100 to 500 mg per day. Optimal dosages vary based on the desired effect, and there is no established optimal range. The maximum safe dose is not well-defined. Timing considerations for supplementation are not well-studied. Grape skin extract is often consumed as a capsule or powder. Absorption of grape skin extract's polyphenols may be influenced by gut health. Specific cofactors required for absorption or efficacy are not well-documented.
FAQs
Is grape skin extract safe?
