The Science of SIRT1

Inside every cell is a guardian protein called sirtuin 1 (SIRT1), short for Silent Information Regulator. It helps decide which parts of your DNA stay quiet and which stay active, helping cells adapt to stress, maintain energy efficiency, and resist the effects of aging.

Commonly known as the "longevity switch," SIRT1 is involved in DNA repair, the removal of damaged cellular components, and the optimization of energy use. As we age, SIRT1 activity naturally declines due to factors such as oxidative stress, poor diet, disrupted sleep, and environmental challenges. This reduction is linked to diminished cellular resilience and many of the classic signs of aging.

The good news is that certain food compounds can help support SIRT1 function. Plant-derived polyphenols such as resveratrol (from red grapes) and pterostilbene (from blueberries) are among the best-studied for their ability to activate SIRT1 and promote healthy cellular aging. These compounds mimic calorie restriction at the molecular level, helping to reactivate SIRT1 and restore youthful gene expression patterns. By boosting SIRT1 activity, they help shift cells into a protective, repair-focused state, supporting the body’s natural defenses as we age.*1-7

Why Resveratrol + Pterostilbene Work Better Together

Resveratrol is well-known for supporting SIRT1, but the body clears it fast. The liver converts most of it into inactive metabolites within minutes. Blood levels fall quickly, so only a limited amount reaches cells. The effect on SIRT1 is meaningful, yet short-lived.*1-3,5-7

Pterostilbene shifts the profile. It is a close relative of resveratrol with two methyl groups that improve its performance.

  • Up to 4× higher oral bioavailability*
  • Greater lipophilicity for superior cellular penetration*
  • Significantly longer half-life in the body (up to 7× longer than resveratrol)*4,14-16

When used together in a balanced ratio, the two ingredients work in sequence. Resveratrol supports a fast SIRT1 response. Pterostilbene keeps that response active for a longer period due to its greater stability. This provides steadier sirtuin pathway support than resveratrol alone.*1-7,14-16

A Word from our Chief Science Officer

"Resveratrol brought SIRT1 into the spotlight, but bioavailability has always limited its potential. By combining it with pterostilbene, we’re matching kinetics with biology — ensuring both rapid activation and sustained support of this key longevity pathway."

Ingredient Info

Trans-Resveratrol: The active, naturally occurring form of resveratrol that supports key cellular pathways involved in healthy aging.*
Trans-Pterostilbene: A lipophilic stilbene that engages the SIRT1 pathway and complements resveratrol for steady cellular support.*

Balls need to squeak out of the box
Color: 12 Tennis Ball
The squeaky ball lights up the faces of my dog shelter furiends, they love to fetch and chew the ball to make it squeaky. I have been buying these balls for about a year now. They don’t last long with some of the dogs, but the joy is worth the price. Lately some of the balls do not squeak right out of the box but many of the balls are fine. Returning the box doesn’t make sense because I used some already so I thought I would comment, dropping one star so far.

Nicer than I expected
Color: 12 Tennis Ball
Much more sturdy than other "squeaky" balls of this type. I love that they have an internal or covered squeaker, so I don't have to worry about my dog chewing it and swallowing a plastic squeaker. But ... what I find as a plus, my dog sees as a minus, since one of his favorite thing is to chew a ball until it stops squeaking. They come in a plastic net bag, which is very handy for storage also.

Squeaks break immediately
Color: 12 Tennis Ball
Squeaks break almost immediately, even with very light chewing. Some are so badly made that the squeaks break after one or two squeezes. Get Kong balls instead.

Nice balls but arrived with a bad chemical smell
Color: 12 Tennis Ball
Wonderful Product!!! The balls themselves are amazing and the squeaker in them my dog loves. I am giving them only a three star because they arrived and they SMELL like chemicals so bad!!! I was afraid to give it to my dog so i washed one out and put it up hoping the chemical smell will go away. This not good for a dog as unknown chemicals can make them really sick. Whatever amazon is spraying on their stuff it's not good

Puppy tested & approved
Color: 12 Tennis Ball
I ordered these squeaky tennis balls for my cocker spaniel. She absolutely loves these tennis balls with the squeakers in them! She plays with them all day, and chews on them frequently. We have not had any problems with her, breaking the tennis balls, which is generally the issue we have with her. The tennis ball fuzz stays on the ball very well, which is usually an issue with standard tennis balls, because my dog likes to peel off the yellow fuzz on all tennis balls. She has not been able to do that with these. I will definitely be buying these again , but will not need to anytime soon as these are extremely well built.
