Grapefruit or grape seed extract? They are two fruits, the extract of which is often used for antioxidant protection. But what are their differences and how can we differentiate their actions? Let’s get to know them a little better!
It is a fruit known as citrus paradisi, of the genus citrus. The fruit plant grows in a similar way as grapes, in bunches, that is why is called “grapefruit”. It has very strong antioxidant properties as it is a very good source of vitamin C. Depending on the variety of grapefruit it can contain significant amounts of lycopene and carotenoids (orange color). Among the ingredients that make it stand out are some phytochemicals like limonoids (d-limonene) and flavonoids such as hesperidin and naringenin.
Through studies, was found that grapefruit helps reduce cholesterol, especially LDL cholesterol and blood pressure. It also reduces platelet adhesion by preventing the appearance of thrombosis. Despite its cardioprotective effect, grapefruit intake is contraindicated by people taking statins, as the drug’s effect is greatly reduced.
Some studies have shown that grapefruit promotes the reduction of body fat and liver fat accumulation due to the polyphenols. Thanks to naringenin, it improves the sensitivity of tissues to insulin and thus indirectly helps prevent the onset of type 2 diabetes. Although its intake is particularly beneficial, it interacts with many drugs and therefore grapefruit needs caution.
Grape seed extract (GSE)
Grape seed extract (GSE) is a nutritional supplement that is rich in proanthocyanidins and catechins, similar to those found in green tea. Its intake has been shown to be beneficial for blood pressure and in particular for systolic pressure. A small but not significant reduction of serum cholesterol levels was also noticed. Nevertheless, it appeared to have cardioprotective properties, improving blood flow respectively to pycnogenol, which is why it is used by people with venous disease, edema, and poor blood circulation.
Grape seed extract has very strong antioxidant and anti-inflammatory properties. In some studies, grape seed extract supplementation has lowered the levels of C reactive protein in the blood, which is an indicator of inflammation. The action is due to reduced activity of certain cells (macrophages) that are involved in inflammation. It does not interact with drugs, making it a relatively safe as a dietary supplement.
