"I had a couple of "sun damaged" spots on my skin that I intended to see a Dermatologist for, one is gone and the other is going away. My husband witnessed it! My skin looks better on my body and my face and I feel better. I do take Krill Oil and a couple of other supplements with the Longevetrol. I am on my second bottle and I will be ordering more!"

"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."

"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.
