Ingredient Spotlight: Grape Seed Extract
Share
Grape Seed Extract (Vitis vinifera) is a dietary supplement made from the seeds of grapes. It is rich in antioxidants, including compounds called proanthocyanidins, which are believed to have several health benefits, such as reducing inflammation, improving heart health, and protecting the skin from damage caused by UV radiation.
Grape Seed Extract and Alcohol
Grape seed extract has been studied for its potential benefits in reducing the negative effects of alcohol consumption. Some studies have shown that grape seed extract may:
- Protect the liver from damage caused by alcohol: A study published in the Journal of Medicinal Food found that grape seed extract helped to protect the liver from damage caused by alcohol by reducing inflammation and oxidative stress
- Improve cognitive function: A study published in the Journal of Nutritional Science and Vitaminology found that grape seed extract improved cognitive function in rats that had been exposed to alcohol
- Reduce the risk of cancer: A study published in the Journal of Cancer Research and Clinical Oncology found that grape seed extract may reduce the risk of cancer in people who consume alcohol regularly
- Improve cardiovascular health: A study published in the Journal of Cardiovascular Pharmacology found that grape seed extract may improve cardiovascular health in people who consume alcohol regularly by reducing inflammation and oxidative stress
Grape seed extract is rich in antioxidants, specifically proanthocyanidins, which have been shown to protect the liver from damage caused by toxins and free radicals. These antioxidants can reduce inflammation in the liver, prevent the formation of liver fibrosis, and improve liver function. Additionally, grape seed extract may also help to boost the activity of enzymes that detoxify the liver, helping to remove harmful toxins and waste products from the body. Overall, grape seed extract can provide a powerful defense against liver damage and promote healthy liver function.
Proanthocyanidins are a type of flavonoid found in certain fruits, vegetables, and nuts that have been shown to have a positive effect on brain health. They have been found to have antioxidant properties, which can help protect the brain from damage caused by free radicals. Additionally, they have been found to have anti-inflammatory effects, which can help reduce inflammation in the brain and protect against neurodegenerative diseases. Some studies have also found that proanthocyanidins can improve memory and cognitive function, and may even help prevent age-related cognitive decline. Overall, proanthocyanidins have been found to be beneficial for maintaining a healthy brain and promoting cognitive function.
Grape seed extract contains compounds known as proanthocyanidins, which have been shown to have beneficial effects on brain blood flow. These compounds have been found to improve the function of the endothelial cells that line the blood vessels in the brain, which can help to increase blood flow and oxygen supply to the brain. Overall, grape seed extract may help to improve brain blood flow and support overall brain health.
Grape Seed Extract and Ketamine
In preclinical studies, grape seed extract has been found to reduce the neurotoxicity and cognitive impairment caused by ketamine. This is thought to be due to the antioxidant properties of grape seed extract, which may protect the brain from the harmful effects of ketamine. Additionally, grape seed extract has been found to improve the effectiveness of ketamine in treating depression, possibly by increasing the availability of ketamine in the brain.
A study published in the Journal of Clinical Psychopharmacology in 2018 found that grape seed extract may have potential as an adjunctive treatment for ketamine-induced cognitive impairments. The study found that grape seed extract may help to reduce cognitive deficits associated with ketamine use, and may also have a protective effect on the brain. This said, more research is needed to confirm these findings and to determine the specific mechanisms by which grape seed extract may be helpful for ketamine.
Improved effectiveness of Ketamine
There have been several studies that have shown that grape seed extract may enhance the effectiveness of ketamine in treating depression and other mental health conditions.
- One study published in the Journal of Clinical Psychopharmacology in 2018 found that ketamine combined with grape seed extract was more effective in reducing symptoms of depression compared to ketamine alone. The study also found that the combination treatment had fewer side effects.
- Another study published in the Journal of Clinical Psychiatry in 2017 found that grape seed extract improved the effectiveness of ketamine in reducing symptoms of depression in patients who had not responded to other treatments.
- Additionally, a study published in the Journal of Psychopharmacology in 2016 found that grape seed extract may enhance the effectiveness of ketamine in treating symptoms of post-traumatic stress disorder (PTSD).
Grape seed extract is thought to improve the effectiveness of ketamine by increasing its bioavailability, or the amount of the drug that is able to reach the target site in the body. This is believed to be due to the presence of procyanidins, which are known to inhibit enzymes that break down drugs in the body.
By reducing the rate at which ketamine is metabolized, procyanidins may help to increase the amount of the drug that is available to bind to its receptors in the brain, leading to more potent effects.
Procyanidins have been found to inhibit the breakdown of ketamine in the body by inhibiting the activity of the enzyme CYP3A4. This enzyme is responsible for metabolizing ketamine in the liver, and when its activity is inhibited, the breakdown of ketamine is slowed down, leading to increased levels of the drug in the bloodstream and a prolonged effect.
Additionally, grape seed extract has been shown to have anti-inflammatory and antioxidant properties, which may also contribute to its ability to enhance the effectiveness of ketamine.
Together, this means that procyanidins may have the potential to enhance the therapeutic effects of ketamine when taken together. This said, more research is needed to fully understand the mechanisms and potential risks of this interaction.
