Red Wine Grape (Vitis Vinifera) Concentrate

Also known as: red wine grape, European grape, grape seed extract, grape skin extract, red grape extract, Vitis vinifera

Overview

Vitis vinifera, known commonly as the red wine grape, is a species native to southern Europe and Western Asia, renowned for its substantial bioactive compounds, which include flavonoids, polyphenols, anthocyanins, proanthocyanidins, and resveratrol. These compounds are predominantly found in the seeds, skins, and leaves of the grape, making these extracts popular for various health benefits. Vitis vinifera extracts are recognized for their antioxidant, anti-inflammatory, antimicrobial, cardioprotective, hepatoprotective, and neuroprotective properties. The effectiveness of these extracts can differ based on factors such as grape variety, environmental conditions, and extraction processes. Robust research supports its therapeutic claims, with a strong focus on cardiovascular health benefits stemming from its rich content of bioactive components.

Benefits

Evidence-based health benefits of Vitis vinifera include significant reductions in blood pressure, with studies noting an average decrease of -2.44 mmHg in systolic blood pressure, particularly advantageous for those at risk of cardiovascular disease. Its antioxidant qualities protect against oxidative stress-related damage, while the plant also demonstrates anti-inflammatory and antimicrobial actions that promote overall wellness. Polyphenols from Vitis vinifera may provide neuroprotective effects, although ongoing research is required to clarify these dynamics. The strength of the evidence varies, with high-quality systematic reviews affirming cardiovascular benefits and other benefits demonstrated by clinical trials and observational studies.

How it works

The health benefits of Vitis vinifera stem primarily from its bioactive constituents, chiefly resveratrol and polyphenols. These compounds modulate various biological pathways, including inflammation regulation, antioxidant defense enhancement, and vascular health improvement. Resveratrol activates SIRT1, a protein tied to cellular health and longevity, while inhibiting NF-κB, integral in inflammatory responses. This dual action contributes to cardiovascular health and mitigates oxidative stress, enhancing immune function and promoting overall well-being.

Side effects

Generally, Vitis vinifera extracts are considered safe when taken at recommended dosages, with mild gastrointestinal discomfort reported by 1-5% of users. Allergic reactions are rare, affecting less than 1% of individuals; however, those with known grape allergies should avoid these supplements. Caution is warranted for individuals taking blood thinners or antiplatelet medications due to potential heightened bleeding risk from interactions. Pregnant or breastfeeding women should seek medical advice before starting these supplements. When consumed within recommended limits, Vitis vinifera extracts maintain a favorable safety profile.

Dosage

For cardiovascular health, recommended dosages of Vitis vinifera typically range from 250 mg to 1 gram per day, with optimal intake often cited between 500 mg and 2 grams, standardized for polyphenols or resveratrol content. Higher dosages exceeding 2 grams are less studied and could present potential risks. To enhance the absorption of bioactive compounds, taking these supplements with meals is advisable; common forms include capsules or tablets with standardized extracts. Individual responses can vary, impacted by personal nutritional status and nutrients present.
