Grape Seed Extract

What is Grape Seed Extract?

Grape seed extract is a dietary supplement that is derived from the seeds of grapes. As a dietitian, I often recommend it to my clients due to its potential health benefits and antioxidant properties. The extract is rich in a group of compounds known as oligomeric proanthocyanidin complexes (OPCs), which are believed to have many positive effects on the body.

One of the key reasons why grape seed extract is gaining popularity is its antioxidant properties. Antioxidants help protect our cells from damage caused by harmful molecules known as free radicals. These free radicals are produced naturally by our bodies but can also be introduced through exposure to pollution, smoking, and certain foods. Antioxidants neutralize these free radicals and prevent them from causing harm to our cells, which can potentially reduce the risk of chronic diseases.

Grape seed extract is also believed to have anti-inflammatory properties. Inflammation is a natural response by our body’s immune system, but chronic inflammation can lead to various health problems. The OPCs found in grape seed extract are thought to help reduce inflammation by blocking the release of certain enzymes that promote inflammation. This can be beneficial for individuals with chronic inflammatory conditions such as arthritis.
