The Ultimate Weapon Against Zombie Cells*

Cellular senescence is a hallmark of aging. Over time, old or damaged cells stop dividing but don’t die—they become “zombie” cells that persist in the body and secrete harmful inflammatory signals, collectively known as Senescence-Associated Secretory Phenotype (SASP). This buildup disrupts tissue function, drives whole-body inflammation, and accelerates biological aging.2,5,7,14

Senolytics—derived from the Latin, "senex" (old) and "lytic" (to destroy)—are compounds that help the body selectively clear these dysfunctional cells, while leaving healthy ones intact. Quercetin, a powerful plant flavonoid, has been clinically studied for its senolytic activity. It works by disrupting the pro-survival pathways that allow senescent cells to linger, triggering apoptosis—the body’s natural process of cellular self-destruction and renewal.*1-4

By supporting the body’s natural ability to manage senescent cells, senolytic compounds like quercetin help maintain cellular health, optimize tissue function, support a healthy inflammatory response, and reinforce resilience with age.*1-4

Introducing: The 5-Day Cellular Reset*

To harness quercetin’s powerful senolytic benefits, we’ve designed the ProHealth 5-Day Cellular Reset protocol aimed at optimizing its role in supporting healthy aging:*2

  • Take six (6) capsules of Pure Quercetin daily for 5 consecutive days.
  • Discontinue use on day 6.
  • Wait 4 weeks before repeating the cycle.

This strategic “hit-and-run” approach supports the body’s natural ability to eliminate senescent cells efficiently. The protocol can be followed monthly—or seasonally—based on your individual health goals and needs.*2,7,9

Note: If this protocol feels too intensive, you can opt for one capsule of ProHealth Pure Quercetin daily for ongoing antioxidant support.*1,3,6,8

A Word from our Chief Science Officer

“Quercetin is quickly emerging as one of the most promising natural senolytics we have—an ingredient that doesn’t just mask the symptoms of aging, but helps the body eliminate the dysfunctional cells that drive it. These senescent ‘zombie’ cells accumulate over time and linger in tissues, silently undermining how we feel and function. The effects can vary depending on where these cells concentrate in the body, but I’ve seen remarkable changes in older individuals using intermittent senolytic protocols.”

Best dog toy!
Color: Multicolor/Alligator & Wild Duck, Size: Medium, Color: Multicolor/Alligator & Wild Duck, Size: Medium
Best dog toy! Most dog toys lady maybe a week or less but this one has been going strong for almost 2 months. Both the squeekers still work on both toys i purchased. My vizsla loves ti squeek and carry it around. We added an empty water bottle in the pocket cavity for some extra fun! Yes, we are still on the same water bottle! Fantastic durability.

Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Super Sturdy with hours of fun.
Color: Wild Duck, Hare, Squirrel & Alligator, Size: Small
I got the small ones that you cannot put a water bottle in. These toys have held up way better than expected. I am dog sitting a very rough with toys dog named Chunk. He tears up ever. Single. Toy my dog (Ted) has. I bought new ones just for chunk. These appealed to me with the no stuffing, They were cheaper, and have a squeaker. Everything chunk needed. They arrived on time and I thought I wasted my money. They were super soft, like too soft. They felt flimsy and weak. Like 5 minutes with chunk and they be dead. 2 hours with my dog and they would have a rip. So far 2 of them (I set two out) have lasted the whole weekend. The bunny looks very rough and disgusting, but no rips, the squeakers still work, and no random fluff everywhere. I am going to wash the bunny once chunk leaves. My very careful doggo Ted loves them too. He throws them up in the air and catches them, plays tug of war with them, and no rips. They are super sturdy. He can’t wait until Chunk leaves (chunk is 2 and Ted is 12-13) so he can play with them.

Loved it
Color: Brown/Wild Duck, Size: Large, Color: Brown/Wild Duck, Size: Large
He loved it so much, he destroyed it so we ordered another. I didn't realize that you can stick an empty water bottle inside. Again, the first one didn't last long, but he enjoyed it

Very fun interactive toy
Color: Brown/Wild Duck, Size: Medium
This toy is very versatile. There's no stuffing yet it's very soft so it can be used as a tug toy. It also makes for a fun fetch toy because it has a cavity to put a water bottle. It gives your dog something that crinkles and can be pierced when bitten and easily replaced with another empty bottle whenever necessary. That is what really makes this toy the standout of all the ones offered by Best Pet imo. I don't expect this to last forever but once my pup gets bigger we'll probably get the large size for her because there's not too many all in one fetch and tug toys at an affordable price.
