What are Polyphenols?

Polyphenols are nutrients found in plants that are responsible for their health-promoting properties. The more colorful the plant, generally the higher the polyphenol content. This is why fruits, especially berries, and vegetables are good sources of polyphenols.

Polyphenols offer plants protection against the sun’s radiation and help defend against disease. Just like they protect plants, they protect us in a similar way by acting as antioxidants to help combat inflammation and aid in improving immunity. They also play a key role in gut health by helping to defend against bad bacteria while increasing the production of good bacteria.

Despite the health benefits of polyphenols, only 1 out of 10 adults meets the recommended intake of fruits and vegetables per day.

Which foods contain polyphenols?

The more colorful the plant, generally the higher the polyphenol content. This is why fruits, especially berries, and vegetables are good sources of polyphenols. Nonetheless, the levels of polyphenols occurring in fruits and vegetables is only between 0.1 and 0.2 percent by weight. Polyphenols can also be found in cocoa, legumes, spices, and plant-derived beverages such as tea, coffee, and wine.

How much should people consume?

The answer depends on your personal goals. There are numerous benefits that come with consuming anywhere between 500mg to 1,500mg of polyphenols per day. Dr. Sears’ recommends aiming for a minimum of 1,000mg per day for general wellness. To give a sense of what 1,000mg of polyphenols per day looks like, it could be approximately 5 ½ cups of broccoli, 1 ½ cups of blueberries, 2 ¼ cups of strawberries or a combination of various fruits and vegetables. A good rule of thumb is that consuming 10 servings of vegetables and fruits per day will provide about 1,000mg of polyphenols per day.

Why Should I Take a Polyphenol Supplement?

Since most of us fall short on our intake of fruits and vegetables, let alone meet Dr. Sears’ recommended 10 servings per day, supplementing with purified polyphenol is a great way to fill in the gaps. Where most fruits, vegetables, and juices can be rich in pesticides and heavy metals, no matter which Zone Polyphenol you choose it has the purity and potency you’ve come to expect from Dr. Sears. It has to because his name is on every bottle.
