Meganatural Gold Grape Seed Extract

Also known as: Vitis vinifera Seed Extract, Grape Seed Extract, MegaNatural Gold, MegaNatural Gold Grape Seed Extract

Overview

MegaNatural Gold Grape Seed Extract is a concentrated dietary supplement sourced from the seeds of the Vitis vinifera grape, mainly cultivated in California. This extract boasts a high concentration of polyphenols, particularly proanthocyanidins, which comprise over 90% of its makeup. It possesses an exceptional Oxygen Radical Absorbance Capacity (ORAC) of over 13,000 μmole TE/g, highlighting its remarkable antioxidant properties. The extract is commonly used to promote cardiovascular health, alleviate inflammation, and manage symptoms related to venous insufficiency. Although clinical studies present mixed outcomes, it is available in both capsule and powdered forms, appealing to individuals seeking to boost their antioxidant intake for overall wellness.

Benefits

Research indicates several health benefits of MegaNatural Gold Grape Seed Extract, particularly in relation to cardiovascular health. A systematic review found an average reduction in total cholesterol levels by -6.03 mg/dL for its users. Moreover, a meta-analysis demonstrated a significant decrease in oxidative stress through a standardized mean difference of -1.04 in malondialdehyde levels, which correlates with lower inflammation levels. The extract also shows potential in regulating blood pressure, especially among those with metabolic syndrome, with positive effects often noted within weeks of use. Generally, individuals at risk for cardiovascular and metabolic conditions may derive the most considerable benefits. However, given the variable quality of supporting research, its efficacy is endorsed moderately.

How it works

MegaNatural Gold Grape Seed Extract enhances cardiovascular function mainly by increasing nitric oxide synthase (NOS), which results in elevated nitric oxide (NO) levels. This boost promotes vascular relaxation and enhances blood circulation, benefiting cardiovascular and endothelial health. Additionally, the proanthocyanidins in the extract play a crucial role in reducing inflammation and lipid peroxidation by moderating C-reactive protein levels, thus further augmenting the overall health benefits.

Side effects

MegaNatural Gold Grape Seed Extract is generally well tolerated, with serious adverse effects reported in less than 1% of those using it. Common mild side effects may include gastrointestinal discomforts such as bloating and nausea. Caution is advised for individuals taking anticoagulants like warfarin, as there may be an increased risk of bleeding, especially for those with bleeding disorders or scheduled for surgery. The safety profile during pregnancy and breastfeeding is undetermined, warranting caution in these groups. While serious side effects are rare, it is advisable for individuals with existing health conditions or those on multiple medications to consult a healthcare provider before consumption to mitigate potential interactions.

Dosage

The recommended dosage for MegaNatural Gold Grape Seed Extract typically ranges from 150 mg to 300 mg per day. For powdered forms, suggested dosages vary from 50 mg to 200 mg per 8 oz serving, with a maximum of two servings daily. Although specific upper limits for long-term use are not established, clinical evaluations suggest that daily doses below 300 mg are generally considered safe and unlikely to provoke significant adverse effects. The polyphenols in the extract show excellent absorption rates, with increases in plasma levels measurable within 90 minutes post-ingestion, effects potentially lasting around four hours.
