My dog Milo has more pep in his step since starting Matterdays! This daily powder mixes easily, and he licks the bowl clean. It supports everything from joints and gut health to overall vitality. Noticeable energy boost in just a few days, I would highly recommend this product!

I have a 20 lb terrier mutt mixture.To be honest, I wasn't sure what this would do for her, but after a few weeks she has more energy and her coat looks the best it ever has. I'm a believer!

"This stuff works."

This supplement is great; both of my dogs had a noticeable improvement in their playfulness and energy levels after 3-4 days of taking. The powder goes on easily and my two dogs; a 60 lb female German Shepherd, and a 65 lb Bernese Golden Mix are much more interested in their kibble with Matterdays on top.

My dog is obsessed with this product! Matterdays is recommended to go in wet food, but I only give my dog dry food so I was unsure of how to apply. I just started sprinkling it on top and she scarfs it down immediately, then begs for more. It smells fresh and has really clean ingredients. We're so happy we tried it!

"Cat longevity and stress resilience-both noticeably better"

The cat longevity supplement space is thin, and most options are reactive rather than prevention-first. MD1 is different; it supports holistic healthy aging and works for cats. Luna has been on it for four weeks. Her vitality has improved noticeably, and her stress resilience has shifted; she's calmer in situations that used to rattle her. Her coat is also in the best condition I can remember. For cat owners who take their pet's longevity seriously, this is the daily supplement worth having.

"I sprinkled Matterdays MD1 and saw a difference"

I sprinkled Matterdays MD1 into my senior pup’s breakfast for a month, and wow—what a difference! This vet-formulated powder mixes in easily (no suspicious side-eye from the doggo) and packs a smart blend and more to support joints, gut health, energy, and long-term cellular vitality. Everything my doggo needs especially now. I want many years with her and this is helping.

After a few weeks, I noticed better digestion (fewer “oops” moments), and that playful spark coming back. It’s not a miracle overnight, but it’s like giving your dog a daily tune-up for more happy, active days together.

If you’re tired of single added supplements, this all-in-one booster is worth trying. Highly recommend for dogs of any age who deserve extra good Matterdays!

"Great Experience - Great product!"

Great Experience! The website made it easy to determine my pets needs and make an informaed decisiomn about his health supplement needs. Delivery was super fast and my black lab has been doing great on it so far! Looking forward to seeing the positive results in the near future!

I wanted to share my experience because it has made a noticeable difference in my dog’s daily life. I’ve seen a positive change in her overall energy and well-being.

What I appreciate most about this company is their absolute transparency. It is hard to find brands these days that are completely open about their sourcing and ingredients. Knowing exactly what is going into my dog's system gives me a lot of peace of mind. If you’re looking for high-quality support for your pet from a company that clearly cares about honesty and results, I highly recommend them!

"Excellent Daily Wellness Supplement for Dogs"

Our dog means the world to us, so I am very intentional about the products we use. What I appreciate most about Matterdays is the focus on transparency, thoughtful formulation, and long-term wellness. The ingredients feel carefully chosen and high quality. Even though our dog can be a bit picky, she takes it without any issue. It is reassuring to find a brand that approaches canine health with this level of care and integrity. I would absolutely recommend it to other dog owners who want the very best for their pets.

"Quality dog longevity powder"

I cannot say enough good things about Matterdays! From the moment we started using it, I noticed a real difference in my dog’s overall energy, coat, and mood. It’s so reassuring to feel like I’m actively supporting their long-term health in such an easy way.

The powder blends seamlessly into meals—no fuss, no picky-eater issues—and it’s clear the ingredients are thoughtfully chosen with wellness in mind. Within just a few weeks, my dog seemed more vibrant, playful, and comfortable, especially during walks and playtime.

If you’re looking for a simple, high-quality supplement to support your dog’s longevity and vitality, I highly recommend giving Matterdays Dog Longevity Powder a try. It’s been a total game-changer for us!

"Prevention-first and every system supported — this is the one"

I don't want to wait until Rosie has problems to start thinking about her longevity. Matterdays is built for that mindset, daily support across every system, science-backed, and zero inactive ingredients. The changes are real: more sustained energy, better gut health, a calmer temperament, and a coat that's noticeably healthier. Her immune resilience also seems stronger, she's been consistently well through a busy social period at the dog park. This is what daily pet wellness should look like.

My dogo loves the supplements and seeing his fur got more soft and shiny after a month of use, also has lots of energy. Will keep this as his vitamin stack every day!

This is great stuff! Clean & efficient packaging & labeling, great to know it has nothing but good, natural ingredients, and my dog (who is a picky eater) absolutely loves it!

My dog only eat dry food, so i was not sure how will matterdays will work. Well, my boy loved it! also, i have some doubts before buying and ill need to confirm that CS is excellent!

I really loved this suplement! First of all, using the website was pretty easy, shipment was super fast and my lab is doing great so far, i think im already seeing positive results!

"Great Company, Even Better Products"

I had a great experience with Matterdays—their supplements were easy to use and my dog genuinely loved them. I noticed a clear improvement in energy and overall vitality, which aligns with their focus on science-backed, preventive pet health. On top of that, their customer service was impeccable, making the entire experience seamless and enjoyable.

"Thank you for making it so easy…."

I love how easy this supplement makes it to take great care of my dog. It’s awesome knowing all the ingredients are high quality, and I’m really looking forward to seeing the benefits. The taste test was a huge success!
