Your body loses its antioxidative defenses during aging. Yet, many age-related changes (the ones that none of us want to see) are often a direct or indirect result of oxidative stress. N-acetyl cysteine (NAC) is a backbone molecule for glutathione, the body’s “master antioxidant.” NAC may also support clearance of toxins to help the body maintain optimal functioning and performance.*

Benefits:

  • Resists oxidative stress*
  • Supports immune, bronchial and respiratory health*
  • Supports liver health and detoxification*
  • Supports exercise performance*

Resists oxidative stress. NAC exhibits direct activity on certain reactive oxygen and nitrogen species due to its unique molecular structure. It also works to help increase intracellular cysteine for the maintenance of glutathione homeostasis. A systematic review and meta-analysis of trials involving NAC supplementation reported significant increases in antioxidant markers including glutathione, catalase, and Total Antioxidant Capacity. Research suggests that NAC paired with glycine, another building block for glutathione, may provide optimal protection from free radicals.*

Supports immune, bronchial and respiratory health. NAC can help modulate critical pathways for an optimal immune response. It can also maintain and support normal physiological levels of mucus in the sinus and respiratory system of health individuals.*

Supports liver health and detoxification. NAC supports the body’s ability to excrete toxins through detoxification pathways by boosting glutathione production. NAC is a source of cysteine, an amino acid precursor for the synthesis of glutathione production. Glutathione is the body’s master antioxidant and plays a crucial role in liver health and detoxification.*

Supports exercise performance. Clinical studies have reported improvements in exercise performance markers in the presence of NAC due to its ability to help maintain free radical balance and support a normal inflammatory response.*

  • NAC helps support many of the hallmarks of aging through its support of free radical protection and glutathione synthesis. Low glutathione levels are common in older individuals.*
  • May work in tandem with glycine to support glutathione synthesis and overall health during the aging process.*

Last a while. Will be buying more toys soon.
Color: Consuela the Cactus - Large, Size: Large Dog
Best dog toy I have ever bought. I have three dogs, two at the time I bought this toy. It took them over a year to break through the first layer. The flower comes off first so be careful your dog doesn't swallow it. It still has the second layer so it still looks like a cactus. No stuffing to clean up when they tear into it, which makes it far less messy than other toys. One of my dogs is obsessed with fetch so I use it like a ball inside. The oval shape makes it hard to ensure when it bounces that it will bounce straight. It's bounced into walls and other stuff that I wasn't intending it to hit. Not much of a squeak so I can let them play with it for hours and I don't get annoyed with the noise. Great toy that lasts a while.

Nice Value
Color: Consuela the Cactus - Large, Size: Large Dog
Very cute! Its soft and feels like it is well made. It is a heavier toy and a tougher one. Not a plush toy. I will order again for our older dogs. Nice value for sure!

Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.
