Some people believe they could help treat a number of conditions, from heart disease to cancer to aging skin, although scientific evidence is mostly lacking for those conditions. However,there is good evidence that grape seed extract can help treat chronic venous insufficiency and edema.

What is GSE good for?

One way GSE may help to improve heart health is by reducing blood pressure. Having higher blood pressure forces the heart to work harder, which can increase the risk of heart attack and heart failure. The results of studies in 2021 and 2023 both suggest that GSE can significantly lower blood pressure.

Is it safe to take grape seed extract every day?

Grape seed extract is generally well tolerated when taken in moderate amounts. It has been tested safely for up to 11 months in human studies. It's possibly unsafe if you have a bleeding disorder or are going to have surgery or if you take anticoagulants (blood thinners), such as warfarin or aspirin.

What does grape seed extract do for testosterone?

The present study demonstrated that GSPE up regulates the serum level of T, which suggests that restored T levels may contribute to the protective effects of GSPE. However how testosterone biosynthesis pathway could be modulated by these extracts is still undiscovered.

Is grape seed extract hard on the liver?

Grape seed extract (GSE) significantly improved the grade of fatty liver change; and resulted in significant decrease in alanine aminotransferase in patients receiving the concentrate compared to those receiving vitamin C independently, from the initial grade of steatosis.

How fast does grape seed extract work?

In most cases, the effects of grape seed extract set in almost immediately. Since GSE is not an essential nutrient, it is not technically possible to be deficient in this substance, but this beneficial extract can address low levels of antioxidants and hypertension within 24 hours or less.

Can you take GSE everyday?

GSE is generally considered safe with few side effects. Dosages of around 300–800 mg per day for 8–16 weeks have been found to be safe and well tolerated in humans. Those who are pregnant or breastfeeding should avoid it, as there is insufficient data on its effects in these populations.

Does grape seed extract increase estrogen?

In this pilot study grape-seed extract given in daily doses of 200, 400, 600 or 800 mg for 12 weeks to postmenopausal women did not decrease plasma estrogens (estrone, estradiol, estrone sulfate) and did not increase precursors of androgens (testosterone and androstenedione).

Is GSE anti-inflammatory?

Finally, our study also revealed that GSE can suppress the expression of pro-inflammatory cytokines and promote the expression of anti-inflammatory cytokines following LPS-induced inflammatory response. We suggest that these effects are mediated by antioxidant polyphenols that are the most abundant compounds in GSE.

What are the side effects of GSE?

Headache, abdominal pain, sore throat, nausea, and diarrhea may occur.
