Combat Aging, Improve Heart Health and Promote Muscle Strength

  • NMN supplementation has been found to improve various parameters of health, including physical endurance and muscle strength, neurological function, heart health, body weight and gene expression.
  • Nicotinamide mononucleotide (NMN) is a derivative of the B-vitamin niacin that dramatically improves health and longevity by serving as a precursor to NAD+.
  • NMN Pro 250 Sustained Release is designed to slow and prolong NMN absorption, allowing a longer steady blood level concentration of the active ingredient. This enables NMN Pro 250 Sustained Release to be given at higher doses less frequently.

Research Supported Benefits:

Supports Longevity. Studies have shown that boosting NAD+ synthesis in the body extends the lifespan of yeast, worms and flies. (1)

Blood Sugar Regulation. As we age, we have more trouble processing glucose, leading to higher blood sugar. Supplemental NMN is shown to improve several markers of skeletal muscle glucose metabolism that are commonly dysregulated in people with metabolic disorders. (2)

Supports Metabolism and Healthy Weight. Although excessive body weight can develop at any age, adults over age 40 are particularly susceptible to age-related weight gain as metabolism slows down and body composition is altered to favor fat over lean muscle. As obese individuals have reductions in both NAD+ levels and ATP (energy) production, replenishing NAD+ through NMN can help to reverse this while improving metabolic pathways to maintain a healthy weight. (3,4,5)

Supports Healthy Cognition. Declining cognitive function with age is related to a reduced NAD+ levels that impair mitochondrial function. Replenishing NAD+ stores through NMN may be able to prevent this dysfunction. (6,7)

Supports Healthy Skin. In our 30s and 40s, the appearance of our skin can start to show signs of age. Several studies have examined how boosting NAD+ levels in the skin prevents premature skin aging or supports a healthier external appearance. (8,9)

  • Nicotinamide mononucleotide (NMN) is a derivative of the B-vitamin niacin that dramatically improves health and longevity by serving as a precursor to NAD+, a compound that plays a crucial role in energy production, metabolism and gene expression in the body. When we boost NMN levels in the body, we can enhance the biosynthesis of NAD+ and alleviate symptoms associated with depletion of this crucial nutrient. NMN supplementation has been found to improve various parameters of health, including physical endurance and muscle strength, brain health, heart health, body weight and gene expression.

Not for gnawers
Size: 11.5 in, Color: Bear
I was hoping this would work for my teenage ACD and save my leather goods from being chewed on. He gnawed on it quietly I was thrilled. But I had to take it from him within a few minutes. Gnawing apparently equals chewing pieces off. Not made for chewers or gnawers. It seemed to be well made, was soft, was actually a fairly good size and didn’t get gross when it got spitty. Just didn’t work out for Captain chaos destructor of all.

Durable & Leather. For Small-Medium Dogs
Size: 15 in, Color: Retriever, Size: 15 in, Color: Retriever
This is a great dog toy! My Pomeranian is a small guy at only 8lbs. but he sure knows how to chew and he does it as often as he can. I was throwing out toy after toy because he was tearing them to pieces after only a half hour or so. After putting my money in the garbage so many times, I decided to search for toys that would hold up to his destructive mouth. I found a lot that claimed they wouldn't fall apart but they were all more than I wanted to spend. I came across this toy and a rabbit shaped one just like this. I bought both months ago and both are still in tact after all this time. Sure the edges are a little frayed but other than that, no damage whatsoever! I'm not sure what dura fused means but that seemed promising to me when I was reading the description, also the fact that they're leather made them seem more durable to me. Both have squeakers inside and some sort of stuffing as well. I throw all of my dogs toys in the laundry or hand wash them once a week, except for these. When these toys get wet with my dogs saliva, they look like they're not meant to get wet. Even without washing, these seem fine. This toy is probably about 9" long or so if I had to guess. In my opinion, it'd be perfect for a medium sized dog. It's a tiny bit big for my little guy but he manages just fine! If you're looking for a durable toy that your small to medium dog can chew on constantly, look no further!

Always looking for less destructible dog toys
Size: 8 in, Color: Squirrel, Size: 8 in, Color: Squirrel
I am constantly searching for aggressive chewer dog toys. So many claim to be and one look and you know they haven’t met your dog!! Our golden retriever is so sweet until he gets his claws and teeth into a new toy. We nicknamed him the shredder, as he rips his new toys to pieces. I accidentally stumbled across this toy. We have never owned a leather dog toy. The squirrel is going to give Maverick a run for his money. The edges are double sewn closed. I am very impressed with the quality of this toy for $5.75 which includes the sales price and an additional 10% off coupon. Even without those two incentives the toy is less than $8 prime. The other shapes are similar or cheaper in price and now I see a 50% off 1 toy coupon when you buy 2. What a deal and the squirrel has a squeaker inside. What I like about the squirrel is that there’s less limbs or appendages for Maverick to shred off. The bunny has ears, the raccoon has hands, the buffalo has legs, the bone and retriever stick have a rope, the bear has a neck and head that could be chewed off, similar to the fox who has a tail and snout. The squirrel looks like it would be harder to destroy! The squeaker was hard to push at first but is easier now. Maverick has a black lab sister who loves squirrels, more so than she loves toys, and I found this toy searching for squirrel toys for her. It is offered in 8 other shapes. The squirrel measures almost 8” tall by 5” wide. It’s perfect for a medium or large size dog. Based on the construction of this squirrel dog toy it looks acceptable for an aggressive chewer and won’t break the bank. It’s very affordable. Always supervise! Updates to follow at Christmas:). BTW, the squirrel did not smell bad upon opening.

Puppy loves it. Well built and fun for her to play with.
Size: 15 in, Color: Retriever
My double doodle mix loved this toy. It is well made and she loves the different texture of the rope. Sadly she has already torn the rope apart and so now it’s just the leather part. This would be the perfect toy for non agressive chewers. Wish the rope lasted a little longer. SPOT is my new favorite company to get her chew toys from now. They’re well built and aren’t expensive like all the other dog toys out there.

Destroyed in under 10 minutes
Size: 9 in, Color: Large Bone
I bought 2 of these toys, one for my 9 year old great dane who isn't an aggressive chewer, and one for my 6 month old puppy who is average. In less than 10 minutes both were destroyed and my dane managed to swallow a good chunk. I wasn't surprised when they both had small holes on the ends and started pulling the stuffing out. The stuffing and squeakers were confiscated immediately, but I let them keep chewing. By the time I came back from throwing the insides away, both dogs had chewed the toys in half and my dane swallowed a chunk when he saw me coming. The puppy was going to do the same thing, but luckily we're working on his "drop" command so he was excited enough for the bigger payout and dropped it. They didn't just come apart at the seams, the whole toy ripped in half making it too easy to swallow. Neither of them are aggressive cheers and the toys didn't hold up at all. A stuffed animal toy would have lasted longer (and has any time I've allowed it). 10 minutes of playtime is probably too generous , but I'm trying to be fair. If I hadn't been right there watching them, they both would have been able to swallow the whole thing in minutes. Definitely not safe for any amount of actual chewing.
