Grape Seed Extract

MegaNatural® grape seed extracts are special seed blends made primarily from varietal California wine grapes. Polyphenols are extracted from grape seeds using hot water. The extract is then purified, concentrated and spray dried into powder. All MegaNatural® products are safe, non-toxic and chemical-free.


The greatness of grape seeds

Polyphenols are phytonutrients that are found naturally in fruits, vegetables and red wine. They have been scientifically shown to support cardiovascular health. Polyphenols are also known for their antioxidant, antibacterial and anti-inflammatory properties. Grape seed extract is one of the largest natural sources of polyphenols.

Our extracts are supported by human clinical research

MegaNatural® products are a distinct form of grape seed extract. They are backed by human clinical research, which is rare in this industry. MegaNatural® products are supported by an extensive portfolio of manufacturing and usage patents, further differentiating them from other commodity grape seed extracts on the market. MegaNatural® helps to fill the need for a natural, effective solution to common health concerns, such as maintaining healthy blood pressure, without the side effects associated with pharmaceutical drugs.

Your blood pressure is important

When blood pressure is healthy, the heart can pump blood at a relaxed pace. Once pressure in the arteries rises, the heart has to work harder to keep blood flowing. This isn’t a problem is the increased demands on the heart are occasional, such as during intense exercise. However, forcing the heart to pump hard all the time puts it under tremendous stress.

Having arteries that are stiff can lead to increased blood pressure. Unfortunately, increased blood pressure then causes arteries to become even stiffer. Thus a vicious self-perpetuating cycle begins.

Frequently Asked Questions

What is an antioxidant?

What does rust have to do with your health? More than you might think. When iron is exposed to air, oxygen triggers a chemical reaction called oxidation. During oxidation, renegade oxygen molecules called free radicals chip away at the composition of the iron. In our bodies, similar free radicals form as byproducts from the “burning” of food for energy and the breakdown of toxic substances, such as cigarette smoke and other pollutants.

Free radicals are also called “oxidants” because they oxidize, or damage, the body’s cells. Over time, increasing numbers of free radicals oxidize various cell parts, including membranes, proteins and DNA. The damage to DNA is particularly serious because it alters our genetic code, making it less efficient, accelerating the aging process and increasing our risk for degenerative diseases.  Antioxidants neutralize, free radicals.

Where do the grape seeds and grape skins come from?

Polyphenolics uses only non-fermented seeds and skins from California wine grapes and juice grapes collected in the Central Valley of California. Constellation Brands, Polyphenolics parent company, is the largest wine company in the world so we have a large supply of raw material to choose from.

What varieties of seeds do you use?

Polyphenolics uses a special blend of seeds from red and white Vitis vinifera grapes.

Is the grape seed extract made from seeds and skins (pomace) or seeds only?

MegaNatural® Gold grape seed extract is produced from grape seeds only. The seeds are separated from the skins and stems prior to extraction. Other Polyphenolics products are made from both seeds and skins, which is also known as pomace.
