Photographic scene of a visibly senior small dog in a natural, calm home setting, full or three-quarter body framing, with a restrained electric-blue glow and subtle semi-transparent cellular-energy overlay concentrated around the torso to visualize internal NAD+ support; warm authentic lifestyle lighting, science-forward but realistic, no embedded words, labels, or product jar

Authentic brand photography, not an AI rendering: the actual PET NMN Longevity Chews for Dogs white product jar beside one clearly visible brown soft chew, paired with a tightly framed, legible authentic Summit Nutritional Laboratories third-party test report showing the product or test identity. Clean bright clinical composition optimized for mobile; no generic amber bottles, no unrelated human supplements, and only include a minimal phospholipid-bubble annotation if it remains clearly readable.

Clean close-up of the dog chew supplement facts and active-ingredient panel with 77 mg NMN, 250 mg glucosamine HCl, and 40 mg trans-resveratrol visible

I have been using this product for several years. But I do use it in complex with NAD+, Green tea, and others from this Renue. I do like their products. And I feel I can trust those products.

Love the simplicity and the concentration means a little goes a very long way. Living in a new higher altitude & dryer climate Renue’s Blue skincare line has been a real game changer. 

Highly recommend

Still early days, so will see how it goes, seeing its works under the skin it will probably take a while to notice

I'm always skeptical when products claim great results but I'm  pleasantly surprised with the RenuebyScience Blue Face Serum! Feels great on my skin & absorbs fast. It really feels great after a red light face treatment.

Feels great on my skin

Annette L.

Absolutely love the formula, texture and scent of this serum! It is packed full of actives and ohhh so good! My skin is loving this right from the start and improving with each use of this RENUE blue face serum! 

Fantastic serum!

Kerry B.

Renue's face serum seems to be pretty effective at improving the health of your skin. I've used Ageless and Particle and I find Renue to be slightly better. Only negative comments is it's a bit watery and unless on sale more expensive than the others mentioned. 

Effective at reducing wrinkles and improving skin tone

Richard S.

I have actually seen a difference using this product- something I can't say for every product I try.  I found it on Tik Tok at discount or I probably wouldn't have tried it but I have to say wow, it works.  I used it before red light and every evening as well.  Works fine with tret and vitamin c.  I had an issue with the pump breaking off and contacted customer service and they replaced it right away.  

Thought I'd give it a try and I love it!

Kimberly M.

The serum is a dull green, different from my last bottle of formula in color by at least one shade. Its more greenish. Its my experience that product turns this shade with age.

Big improvement on energy and deterioration of her muscles in back legs. This is an excellent product especially as your dog gets older. Highly recommended product. You will see changes around 20 days in approximately and you will probably really notice it by the 40day mark

Great for older dogs and those approaching

my mini schnauzer was having a hard time moving around.. been on this a couple of weeks and he is back moving around all now. Just trying to keep him alive. Tried lots of stuff but this seems to be working best for him now… had him on galliprant, wuffles, cosquin, adequan, LIbera, etc… 

Helps my 18 year old mini schnauzer… just trying to keep him alive

My beagle loves these chews and her activity is like that of a puppy! She is well toned and muscular.  Even the Vet was impressed with her muscles. I attribute a lot to these chews.

Blossom, my beagle loves her longevity chews!

Fast delivery  and lots of good people products too! . At 13.5 years old is holding his own. I take NMN so it’s only fair he gets some too.

Nine year old female Boxer with advancing spinal neurological disease whose mobility seems to have stabilized since taking increased dosage of NMN chews.

This is my 3rd purchased the MNM supplement, and I couldn't be happier with the results! From the first week, I noticed a significant boost in his energy, which has made a big difference in his daily routine. He doesn't like the taste so a honey coated.

What I appreciate most is how it supports not just physical health but also mental clarity. I feel Andy is more active through out the day 

Overall, I highly recommend MNM to anyone looking to enhance their beloved dog's wellness journey. It's become an additional supplement in his routine, and I’m excited to continue seeing the benefits!

Our 13 year old Chihuahua has been enjoying the NMN for over 6 months, now. He has SO much energy and vitality! You'd think he was a puppy, not a senior!

I have a 10 year old chihuahua mixed. I started using this supplement combined with healthy home cooked diet, she is definitely healthier. 1 cube per day mixed with cooked food at night. I am a satisfied customer of Renue for several years for my daily maintenance.

Thank you for making pet MNM available!!!

My little one was 12 when I started her on nmn. Her life span for her breed is 10-12. She was laying around. Couldn’t jump up on my bed anymore. Just sad to see her decline. Then I started her on NMN. What could we lose. Her health and quality of life was slowing down. Then I started her on NMN. She has been on these for about a year and looks and acts like a puppy again. The Vet couldn’t believe her own eyes.

Very good 👍 she can jump on my bed again 😀

Great product which has increased my cats energy levels!

Udara W.

I get these Longevity Chews for my next door neighbor’s cat named Kitty. She’s over in my yard and on my porch a lot so I also keep water for her. But, she definitely likes these chews; she comes over specifically for them. If she hears my door open she comes directly over and looks up at me. She gets two, given one at a time, and then she’s on her way.

Kitty loves them!

Marilyn M.

My male cat is 10+. He likes the pieces by themselves or when I crush them and sprinkle over hus dinner. I've noticed no stomach upset. This is my second order.

My cat thinks they are treats. :)

Bonnie B.

Thank you so much for this amazing supplement for cats. My two old cats love it so much that they always start meowing as soon as I open the lid of the supplement. I am really happy to see them more energetic after taking it. Will continue to order it.

Best purchase ever!

Leo is 11 years old and he loves the Cat Chews so I don't miss a day to add it into his breakfast. Thanks!

Cat Chews

Kathy K.

My cat really likes these and makes demands if I have forgotten to give them to her. She is not the pickiest eater (for a cat) and will eat anything high in animal protein and/or fat. She can't eat them whole, and has some issues with chewing larger bites, so I break them in half. She is only 5 years old and might be too young to see results but I think she has had more energy since starting these and she seems to be losing weight quicker on her diet. I will keep buying them as they are well tolerated and I hope to have her around for many years. I know what a difference Renue lipo nmn has made in my health!

Tasty treats

ErikaT

Unfortunately my cat is not liking it but a friend's cat loves them to soon to tell but having said this l have ordered the human nmn and am sprinkling it on his food 5grams per day divided into four feeds

I immediately felt the difference in my runs. Where as I was struggling to get through my 4th, 5th and 6th mile I am no longer struggling. An issue that has come along with aging in the last 2 years. I felt like I was running like my old self. I cant wait to feel what week 4, 5, and 6 feels like. 
I have been taking this only 1 week so far. 

NMN Pure Powder has made a difference

Great flavor and smooth texture! I am so impressed by how good this tastes. The powder is incredibly fine and definitely not grainy like other brands I’ve tried. Taking my 2 scoops a day is super easy because it dissolves completely and tastes great.

Absolutely love this powder!
