What Does Grape Seed Extract Do For Men Testosteron? Uses, Benefits & Side Effects

Written by Dr. Amber Jones

Testosterone is a vital male hormone and a powerhouse behind various bodily functions. While testosterone is associated with men, they are even present in women, but in a very small quantity.

Producing and maintaining the right testosterone levels (between 265 to 923 ng/dL) is crucial for bone density, muscle mass, strength, and overall vitality in men.

However, as time ticks forward, testosterone levels may start declining naturally. It is when nature may offer help, perhaps with the Grape Seed Extracts.

What is Grape Seed Extract? Does Grape Seed Extract Affect Testosterone Hormones?

Grape Seed Extract is a concentrated substance typically obtained from seeds of red grapes. The extract contains a concentrated dose of flavonoids, procyanidins, and polyphenols. These compounds are known for their anti-inflammatory benefits, antioxidant properties, improved heart health, and more.

So, Do Grape Seed Extracts Boost Testosterone? Grape Seed Extract Uses For Testosterone

The potential impact of Grape Seed Extract on Testosterone levels requires an understanding of different complexities. Although it is commonly believed that Grape Seed Extract increases testosterone levels, contrary to this, it doesn’t. Instead, Grape Seed Extracts are rich in Procyanidin B2 (an aromatase inhibitor) that may inhibit the production of aromatase retaining existing testosterone levels for a longer duration. Let’s understand it:

Aromatization is a common process where testosterone (primary male hormone) is converted into estrogen (primary female hormone) by the enzyme aromatase. Since Grape Seed Extracts is a rich source of Procyanidin B2 (an aromatase inhibitor), it may help optimize testosterone levels, especially amongst bodybuilders, athletes, etc.

However, there’s a caution before action. Despite the lab testing proof of Grape Seed Extracts as an aromatase inhibitor, there are conflicts on its application, usage, and benefits in the real world. Since Procyanidin B2 proves difficult to digest and absorb, its benefits for boosting testosterone levels may be limited. Also, limited research on this approach may raise more questions about its effectiveness.

Final Thoughts

Grape Seed Extract may have an impact on testosterone levels, however for increasing/ regulating testosterones, it cannot be the only solution. Grape Seed Extract as a supplement for testosterone is over-hyped however the results aren’t as impressive as other testosterone-increasing supplements. Also since the compounds present in Grape Seed Extract don’t fully absorb into the body, their result can vary from individual to individual.

Therefore, if you are dealing with any issues with testosterone production, it is better to consult a healthcare professional before using any such supplements. Although Grape Seed Extract is quite healthy it cannot be the most reliable nutrient for male hormones. Also, do not overlook the side effects when consuming these supplements.
