NSI Longevatrol Stabilized Polyphenol Complex -- 200 mg - 120 Softgels

NSI Longevatrol Stabilized Polyphenol Complex -- 200 mg - 120 Softgels

Supports healthy blood pressure and cholesterol levels. Promotes cardiovascular health and encourages antioxidant activity within the body. How does NSI® Longevatrol™ Stabilized Polyphenol Complex work? Red wine is well-known for promoting a healthy heart and healthy cholesterol levels. Researchers believe that resveratrol, a polyphenolic compound found in certain foods including grape skins and red wine, is responsible for these benefits. Polyphenols are plant-derived chemicals with certain properties believed to promote antioxidant activity, cleansing, inflammation reduction and skin rejuvenation within the body. Resveratrol is produced by plants in response to injury or fungal infection. It also protects plants from UV radiation and other harmful substances. Resveratrol is believed to promote similar protective benefits in humans. Its antioxidant activity, or ability to neutralize free radicals (unstable molecules that attack healthy cells and damage membranes and DNA), may account for its cardio-protective effects. Resveratrol appears to promote healthy blood composition and circulation, and may also reduce incidence of inflammation. A recent landmark study from Harvard Medical School, published in the medical journal Nature , found that ultra-high doses of red wine extract with resveratrol allowed obese mice to eat a high fat diet and still live a long and healthy life¹. Researchers discovered that the liver and other systems in obese mice remained healthy, and fat-related deaths dropped 31 percent for those taking a resveratrol supplement. Unlike other resveratrol supplements, which may contain molecules that have broken down over time, NSI® Longevatrol™ Stabilized Polyphenol Complex is sealed in airtight, liquid-filled capsules (Licaps®) to ensure stability and preservation of resveratrol. Each single capsule serving delivers 100 mg of Polygonum cuspidatum standardized to 50% resveratrol, plus 100 mg of red wine extract, standardized to 40% polyphenols. NSI® Longevatrol™ Stabilized Polyphenol Complex is better because it:. - Offers the antioxidant and cardio-protective benefits found in red wine. - Features a unique liquid delivery system that provides rapid absorption and preserves the integrity of its ingredients. ¹ Baur J, Pearson K, Price N, Jamieson H, Lerin C, Kalra A, et al., Resveratrol improves health and survival of mice on a high-calorie diet. Nature. Advance online publication, November 1, 2006.  . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"I guess I didn't realize what this stuff will do. I have taken Longevatrol for two weeks and my hair grew 16" in that amount of time. My eyes turned from dark brown to hazel. My voice became younger sounding....in fact my son thought I was trying to mimic Mickey Mouse. The next two weeks should be interesting."

"When I first started taking this I tried one in the morning and one in the evening. I don't reccommend doing this because I was trembling with energy. One thing I did notice was though it acted like a diet pill (energy, appitite loss etc...) I didn't crash like I did on diet pills."

"BUT ! Who knows in the long run how it may help humans. Recently i`ve read that they now find that it takes much less than they previously thought to get the benefits from resveritrol. It seems it`s more important to take it over a long period of time. I`ll be updating this again in about 120 years so stay in touch and keep taking your Longevatrol."

"I am not sure how to rate this product. I have taken it for over a year and will continue to take it on the basis of the research that shows some potential anti-aging or antioxident efficacy. Do I feel better? I feel the same. Quality of the product? I certainly hope so, the same for effectiveness! Value? I guess so. Satisfaction? The company responds quickly to my reorders so I am satisfied. I guess if I live 10 or more years past my projected lifespan then I will have benefitted from this product."

"Bioavailability has been a major shortcoming with Resveratrol/Polyphenol complexes.
Longevatrol appears to have overcome these difficulties and I am confidant there are increased quantities available for absorption.
I give Longevatrol to all my family members including my golden retriever who is equivalent to 80 + human years. He hugely enjoys a vigorous life. As well I recommend it to all those I care for.
--GREAT PRODUCT--"

"If the product was 1000mg instead of the tiny 200mg this would be a five star product. You need to take about 2 grams a day according to most research for this product to be effective. That would require 10 caps a day and at this price point would become very expensive. Please increase the size to 1000mg."

"Some benifts noted since I started: Lower blood pressure, easier breathing during workouts. Recommend doing a search on this product to find the full benifits of this product. Recommend NSI brand because the product is contained in LiCaps. Resveratol reacts when exposed to light potentially losing its effectiveness, so
it is important to ensure it is contained in LiCaps. NSI has always appeared to do their research on suppliment delivery and always
offers a great price."

"In taking this product for about two months, I am hoping to get the benefit of Red Wine, without having to drink so much wine.
I will probably not have an opinion on the effectiveness of Longevitrol for many more years.
There are no apparent side effects observed from taking Longevitrol."
