Research-Supported Benefits:

Supports Cellular Health. Studies suggest astaxanthin supports cellular health by reducing oxidative stress, which contributes to accelerated cellular aging. Astaxanthin’s antioxidant properties protect cells from oxidative damage, improving mitochondrial function. (1)

Protects Against Brain Aging. Research shows astaxanthin exhibits neuroprotective effects, reducing symptoms associated with brain aging. The neuroprotective effects of astaxanthin may be attributed to astaxanthin’s ability to increase BDNF (brain-derived neurotrophic factor), a critical protein that plays a role in memory and learning. (2)

Enhances Heart Health. Animal studies suggest that astaxanthin has cardioprotective properties, reducing cardiac dysfunction associated with elevated blood pressure. (3) Additional research shows that by activating SIRT1, astaxanthin may protect against cardiac damage resulting from a high-fat diet. (4)

Promotes Joint Health. Astaxanthin supports joint health by inhibiting inflammatory-related processes within cartilage cells and reducing degradation of cartilage. (5)

Promotes Eye Health. By improving ocular circulation and protecting against eye-damage associated with computer work, astaxanthin’s powerful antioxidant properties support visual function. (6)

  • Astaxanthin is a carotenoid antioxidant that is primarily obtained through dietary sources such as microalgae and certain seafood like salmon and krill.
  • Astaxanthin functions as an antioxidant to reduce levels of oxidative stress, a key contributor to cellular aging and declining healthspan.
  • Oxidative stress contributes to elevated inflammatory markers, cognitive decline, joint deterioration, vision decline, and increased risk of cardiovascular issues.
  • Studies show that reducing oxidative stress with astaxanthin improves joint, brain, heart, and eye health.

3.5 Stars -- Sturdy but Limited
Color: Purple, Size: Large (Pack of 1)
I got the Barnacle toy in size Large for my ~45 lb mutt. She enjoys food toys, and I wanted to find one sturdy enough that I felt safe leaving her with when I left for work since she tends to destroy her toys quickly. First thing -- there's no way any dog is going to be able to destroy this. The "rubber" is super thick and a good balance of flexible and sturdy, so she can't do her favorite "pick at a weak edge and slowly disembowel it" trick. I've had it for a couple months now and it looks brand new. However, it isn't great for feeding her kibble. She eats 1 cup at morning and at night, and none of the compartments fits that comfortably. I don't really feel like dividing her food into 3 portions every day to split it between either. The bigger problem is the hole size, or rather the ratio of kibble-to-hole size. The holes are very big with rubber "fingers" inside to slow the food spill. I've still found that it tends to dump a fistful of kibble all at once, or not let anything go for a long time. This may have to do with my dog's "technique", as described below. Another problem is that since this has three separate chambers, this toy is not hollow and is surprisingly heavy. While my dog has no problems throwing a kong around (and I mean THROWING a kong around), the weight and asymmetrical shape makes it difficult to throw or roll, which is my dog's preferred way to use a food toy. This toy works best when a dog slaps it with her paws or picks it up and drops it, which may be why my dog gets frustrated with getting her food from it. What this toy is really great for, for us, is high value treats. If I am leaving at an unusual time and anticipate that she's going to fuss, I can put "the good stuff" in this toy and then she doesn't mind the struggle at all! The different size chambers make this especially nice if I'm breaking up odd sized or home made treats and want her to stay busy for a while. Since it's so sturdy, she can chew on it all she wants, but she has to do the work to get the treats. All in all-- this toy isn't great for my dog's daily feedings, but it's great for high value treats and a change of pace.

Actually a challenge for my genius dog!
Color: Purple, Size: Large (Pack of 1)
I am pretty sure my dog owns every puzzle toy and treat-dispensing dog toy that exists, and he's able to figure most of them out in less than 5 minutes. Many last no more than 60 seconds before he's solved them. The Barncle, however, is actually a challenge for him! The Barnacle has three "compartments, " none of which are connected. All three have a rubber "mouth" that helps keep treats inside. The rubber "mouth parts" are very effective and make it quite challenging to get treats out once they've been placed inside. You can trim the rubber "mouth parts" to make it easier to let treats out, but I'm not doing that. I'm glad that it's not challenge! The Barnacle keeps my dog occupied for at least 30 minutes, which is a LONG time for my dog who usually has a "What next?" attitude towards toys. Th only "bad" thing about the Barnacle is that it's so hard to get treats out of, even for humans. Therefore, it could attract vermin if you're not careful to clean it out.

Great toy for dispensing dinner!
Color: Purple, Size: Large (Pack of 1)
This is one of my puppy's favorite toys! We always try to use toys to dispense his meals, but many of them become too easy for him. Kongs take no time at all to empty. This one seems to provide much more of a challenge, mostly due to the three different sizes of compartments and openings. He'll empty the largest compartment fairly quickly, but the small one almost always has a piece or two of kibble that he just can't get out. This helps to keep him interested in the toy throughout the day. We use a large breed dog food with larger sized kibble which helps to add to the challenge. The fact that this bounces erratically and doesn't roll smoothly makes it difficult for my dog to develop a method for emptying it quickly. With some other toys, like the Kong Wobbler, he quickly learns to just push it around with his nose. This toy makes him work much harder! The construction of this toy is very sturdy. We usually feed one meal a day in this, and it's held up well to heavy chewing. I (and my roommates) appreciate that it's made of softer plastic which doesn't make as much noise on the hardwood floors as some of his other toys. The prongs on the openings can be cut to adjust the difficulty, which is nice if you're using different sized kibble or treats. It is a little harder to fill than other toys, but still not terribly difficult. Overall I've had a great experience with all the PetSafe toys I've tried, and this one is one of the very best!

Great chew toys!
Color: Purple, Size: Medium (Pack of 1), Color: Purple, Size: Medium (Pack of 1)
Keenan LOVES this toy! He will play with it all day. Running around the house, chasing as it bounces in different directions. And he'll be so content chewing on it for long periods of time. It makes an annoying sound when he chews, but I can live with it if it's keeping him entertained. This is the second purple rubber toy from this brand that I've purchased, the other being the squirrel one, which was his favorite until I purchased this for Christmas. They are super durable, his squirrel is still going strong. Even without putting food/treats inside, these are great toys for dogs that enjoy the softer rubber type chew toys. My only con is that it's a little big for him. He weighs 70lbs and I got the medium. It's fine but he has a hard time carrying it because of its size/shape, and he can't catch it when I toss it to him. Think I'm gonna buy the small size to see if it's any better.
