How Grape Seed Extract Safeguards Blood Vessel Health

How Grape Seed Extract Safeguards Blood Vessel Health

Blood pressure is a key indicator of cardiovascular health, so keeping it in the normal range is vital. Grape seed extract is a mighty antioxidant that may help us maintain healthy blood pressures. It also promotes healthy blood vessel function and protects our cells from free radical damage.

How does this extract work in the body to safeguard cardiovascular health? Read on to find out!

Artery Elasticity is Crucial to Healthy Blood Pressure

Blood pressure is the force exerted against artery walls as our heart pumps and blood courses. The intensity of that force depends on the volume of blood and artery flexibility. Our hearts work harder when blood pressure rises, like when we exercise vigorously. After exercise, blood pressure typically drops back to normal ranges within an hour or two.

Our arteries’ elasticity is crucial to this process. A thin layer of endothelial cells lining the vessels help regulate this process. As we age, our vessels lose this elasticity and the ability to relax and contract. They may not be able to expand as well to accommodate increased blood flow. Then, the heart has to work harder and blood pressure increases. If blood pressure stays high, it can cause arteries to stiffen even more, creating a cycle that stresses the cardiovascular system.

Ways Polyphenols Promote Cardiovascular Health

Plant-based compounds called polyphenols can help. They promote cardiovascular health by helping to improve the function of the endothelium (thin lining of the heart and blood vessels), increasing protective HDL (good) cholesterol levels, and decreasing LDL (bad) cholesterol levels. Polyphenols also have an anti-inflammatory affect and provide whole-body antioxidant protection, scavenging for free radicals that damage our cells and neutralizing them.

MegaNatural®-BP Grape Seed Extract (GSE) is a unique, patented extract that’s 90% polyphenols. In studies, it helped people keep their blood pressure normal ranges. GSE stimulates the production of vasodilator nitric oxide (NO), which helps blood vessels stay flexible to accommodate increased blood flow. This assures that oxygen and nutrients circulate to all our tissues.

Grape seed extract provides powerful antioxidant protection

MegaNatural®-BP GSE Traceable to Vineyard

In addition to being clinically proven, this blend is traceable to the California vineyard where the grapes are sustainably grown. It’s made with a hot water extraction process, so there’s no chance of chemical or solvent residue.

Plus, the extract is layered into our proprietary vegetable wax tablet core for a sustained release of nutrients over five to seven hours. Take one daily with a meal for antioxidant and blood vessel health support.

As with any new supplement, please talk to your health care provider before adding it to  your daily regimen, especially if you take blood thinners.
