Inflammation is another factor that can impact heart health and heart rate. Grape Seed Extract has been shown to possess anti-inflammatory properties, which may help reduce inflammation in the cardiovascular system. By doing so, it could potentially improve heart function and contribute to a more stable heart rate.

3.3 Vasodilation
Grape Seed Extract may also have a vasodilatory effect, meaning it can help widen blood vessels. This action can reduce peripheral resistance, leading to a decrease in blood pressure. As a result, the heart does not have to work as hard to pump blood, which could indirectly influence heart rate.

3.4 Interaction with Nitric Oxide
Nitric oxide is a molecule that plays a crucial role in the dilation of blood vessels. Grape Seed Extract may increase the production of nitric oxide, which can lead to improved blood flow and a more efficient cardiovascular system. This can potentially result in a lower resting heart rate.

3.5 Impact on Autonomic Nervous System
The autonomic nervous system (ANS) regulates heart rate through its sympathetic and parasympathetic branches. Some research suggests that Grape Seed Extract may have an impact on the ANS, potentially modulating heart rate through its effects on neurotransmitters and other signaling molecules.

3.6 Direct Cardiac Effects
While less common, there is a possibility that Grape Seed Extract could have direct effects on the heart muscle itself. These effects could include changes in the electrical properties of the heart, which could influence the rate at which the heart beats.

It's important to note that the mechanisms of action for Grape Seed Extract's potential effects on heart rate are not fully understood and may vary from person to person.
