Nutra Thrive Review: Legit or Hype?

Published on: Jan 9, 2019

Nutra Thrive from Ultimate Pet Nutrition is an all-natural, superfood pet supplement you add to your dog’s food that provides, the company claims, a balance between good and bad bacteria and promotes healthy digestions.

What makes the product unique is its widespread claimed effects on your dog’s health, which, according to the product’s website, helps your dog “live a long, happy life.”

The supplement is the creation of Dr. Gary Richter, “one of America’s most renowned holistic veterinarians,” the site says. Richter runs Ultimate Pet Nutrition, the company behind the supplement. At the time of publishing, the company’s only product was Nutra Thrive.

Richter is also the author of a book titled, “The Ultimate Pet Health Guide: Breakthrough Nutrition and Integrative Care for Dogs and Cats”. At the time of publishing, the book had 57 reviews on Amazon for an average rating of 4.3 stars.

The supplement seems to have all the pedigree you’d want out of a dietary supplement for your dog. However, it's going to take some deeper analysis to understand how the product works, what’s in it and what the American Kennel Club says about the possible side effects of this supplement.

We’ll also discuss Nutra Thrive’s pricing as well as our general thoughts about its pros and cons.

How to Use Nutra Thrive

This supplement comes in powdered form and is intended to be used at every meal. It’s flavored like bacon and includes a variety of “vitamins, minerals, antioxidants, and digestive enzymes.”

You simply add the proper dosage to your dog’s bowl of food, pour in a bit of water into the bowl and then mix the food and supplement around until you can’t see the powder anymore and it’s evenly coating the food.

The website notes that you’ll need to stir your dogs’ food more if you can see any Nutra Thrive. If you need to add more water to finishing mixing the power in, go ahead.

Here’s a quick breakdown of the dosage suggestions that Nutra Thrive provides:

  • 0-30 lbs.: 1 scoop per meal
  • 30-50 lbs.: 1 ½ scoop per meal
  • 50+ lbs.: 2 scoops per meal

If your dog eats twice a day, then you give half the recommended dosage at each feeding.

This pretty much sums up how you’ll give your dog this supplement on a day-to-day basis.

As for which types of dogs can use this supplement, the website notes that it’s best-suited for any dogs that are suffering from conditions that “could be caused by insufficient nutrition.” An example of these conditions include, but aren’t limited to:

  • Bad smells
  • Flatulence
  • Tiredness
  • Abnormal stools
  • Achy joints
  • Anxiety
  • “Lackluster coat”

The real question is whether or not the ingredients in Nutra Thrive will work. We will address this in the next section.

Nutra Thrive’s Ingredients, Their Benefits, and Possible Side Effects

Nutra Thrive has three main groups of ingredients that they call the Superfoods Blend, Super Canine Blend and their Probiotic & Enzyme Blend.

The product’s website provides a photo of the back label, which allows you to see exactly which ingredients they include in each of the blends featured in the pet supplement. The following bullet points list some of the ingredients in each blend:

  • Superfoods Blend: Carrot, Reishi, shitake and maitake mushrooms, Methyl-sulfonylmethane , Spirulina, Chlorella
  • Super Canine Blend: Glutathione inactive yeast, Beef liver
  • Probiotic and Enzyme Blend: Lactobacillus casei, Lactobacillus plantarum
  • Vitamin and Mineral Blend: Kelp, Biotin, Riboflavin, Folic acid

Detailing each of the ingredients would be tedious, so we’ve done some research on one or two ingredients in each blend, or the blend in general.

The American Kennel Club (AKC) notes that mushrooms aren’t necessary for a dogs diet but that carrots are a great alternative.

“Dogs do not need mushrooms in their diet, so play it safe and give them a different reward, like a carrot stick or slice of apple, instead,” the AKC’s mushrooms page says.

If you are going to give your dog mushrooms, the AKC recommends giving them to your dog plain and without spices or oils, which Nutra Thrive does.

Glutathione is an antioxidant that earns high praise from Dr. Deva Khalsa, a homeopathic vet who wrote an article in Animal Wellness magazine about the ingredient’s benefits.

“Though small, glutathione is the uncontested king of antioxidants. Without it, all your dog’s cells would disintegrate and die from unrestrained oxidation,” Khalsa writes.

However, she goes on to say that the antioxidant is useless when ingested orally because the body digests it and excretes it before it can provide health benefits.

“Since this antioxidant is made up of three amino acids, the oral route of administration simply does not work because the glutathione is digested,” she wrote. “For example, asparagus contains more available glutathione than any other food, but the GI tract digests most of it.”

Probiotics are a booming industry for humans and they’re becoming a big deal in the pet world, too. The AKC says that probiotics can be helpful for your dog’s gastrointestinal tract, especially if they’re prone to getting diarrhea when they’re nervous or stressed.

However, the evidence the AKC presented about the anti-diarrheal powers of probiotics related to Bifidobacterium animalis and not the two bacteria in Nutra Thrive. They do point out, however, that Lactobacillus casei, which Nutra Thrive includes, is naturally present in your dog’s gut.

The final group of ingredients is the vitamin and mineral blend and It's here where we find a few ingredients proven to be beneficial for your pup. Biotin is well-known for helping create a shiny, lustrous coat and strengthen tendons and ligaments.

“Giving your dog food with biotin can aid with healthy skin and coat for your dog as well. However, biotin also does even more for dogs. Biotin supports connective tissue within your dog’s body as well,” dog-walking site Wag Walking noted in a post about biotin. “Naturally found in meats, dogs with a healthy diet will get the biotin they need from their high-quality dog food.”

We read a few sources that noted riboflavin can help with your dog’s coat, too.

As for folic acid, Dr. Barbara Forney, a veterinary practitioner in Pennsylvania, noted in a post for Wedgewood Pharmacy (for pets) that the ingredient has some very specific uses and that its effectiveness could be altered if your dog is taking certain drugs.

“Before administering supplemental folic acid … folate levels should be established,” she noted in a post about folate.

Based on our research, we believe the reputable sources we consulted indicate that some of the ingredients in Nutra Thrive will benefit your dog (biotin, for example) and some will pass through your pup’s digestive system without much effect on their health (glutathione).

As for side effects, we didn’t find any dangers related to the ingredients we focused on. For example, Forney noted that dogs will break down or pee out the excess folic acid they ingest.

Nutra Thrive’s Pricing

At the time of publishing, Nutra Thrive sold one 114-gram jar of their supplement for $69.99. Three jars were $188.97 and six jars were $356.95. All pricing tiers include shipping. The site also offered a new-customer promotion with pricing tiers of $49.99, $134.85 and $254.70, respectively.

Each jar has 30 scoops in it, which means dogs of 0-30 pounds will need one jar a month. Dogs weighing 31-50 pounds can get 20 days out of the jar and dogs weighing more than 50 pounds will get 15 days out of the jar.

So, if you have a big dog that requires two scoops per serving, you’ll need two jars to make it through the month. Over the course of one year, here’s how much Nutra Thrive would cost you based on their weight, assuming you buy six jars at a time and you get the new-customer discount on your first order:

  • Small dog (0-30 lbs.): $611.65
  • Medium dog (30-50 lbs.): 968.60
  • Large dogs (50+ lbs.): $1,325.55

Nutra Thrive’s fine print notes that it will take 10-15 days for the supplement to arrive after you order it.

If you aren’t happy with the supplement, you have 90 days from the day the product was shipped to start a return in order to get a refund.

According to the fine print, you’ll need to call Nutra Thrive’s customer service line at 800-604-5827 to get the return started. They note that, “your refund will be processed once your returned Product(s) has arrived at our shipping facility.”

How Nutra Thrive Compares to Other Dog Supplements

Nutra Thrive isn’t the first dog supplement we’ve reviewed. ActivPhy is the other competing products we’ve analyzed.

ActivPhy is available on Amazon and at Petco and they manufacture their bottles of chewable supplements based on your dog’s size. So, for smaller dogs (0-30 lbs.), you’ll get a 90-count jar and for bigger dogs (30+ lbs.) you’ll get a 75-count jar.

At the time of publishing, you could buy a 75-count jar for $24.99, which means that, over the course of one year, ActivPhy is a better value than Nutra Thrive. However, ActivPhy focuses on joint health, whereas Nutra Thrive focuses on overall health.

DOGgeviti is similar to ActivPhy in that it’s a far cheaper option than Nutra Thrive. For example, a year-long supply of the supplement for large dogs costs around $480. This particular supplement focuses on back, hip and joint pain, as well as anti-aging.

In general, we think that your choice of dog supplement has a lot to do with the conditions from which your dog is suffering. If he or she has joint pain, ActivPhy and DOGgeviti seem to be the better choices. If it’s overall health you want and you’re interested in pet probiotics, then Nutra Thrive could be the best option.

If it’s only probiotics you want, online pet stores like Chewy.com have a host of probiotics they offer that are as cheap as $10.99.

The Final Word: Our Thoughts About Nutra Thrive

After taking a few minutes to look over the analysis we did and to read through some expert sources who address supplements, we believe that Nutra Thrive has some clear strengths and weaknesses.

As for the strengths, Nutra Thrive has ingredients that can help your dog. For example, biotin is known to improve your dog’s coat and help with dry skin. Lactobacillus casei is a probiotic that may be able to help your dog with digestive issues like diarrhea.

However, there are other ingredients that experts say may not have a big effect – if any – on your dog’s health. For example, a vet noted that glutathione will pass through your dog’s body with little effect on your dog’s health. Folic acid could help your dog but you’d need to have your vet check your dog’s folic acid levels before taking Nutra Thrive, another vet pointed out.

And, there’s the issue of dog supplements in general. The AKC concludes that dog supplements can be helpful but there’s sparse research about the long-term effects.

“Whether herbal or lab-formulated, there is some evidence to suggest that supplements can be helpful. There has been little-to-no research on long-term effects, but some studies and anecdotal evidence have shown successful results, whether in the form of a shinier coat, peppier step, better digestion, or improved cognitive function.

  • Peanut Butter loves the gravy

    • Tarpon Springs, FL,
    • Aug 21, 2019

    I didn't know anything about Nutra Thrive but after reading the info I took a chance and ordered one jar. Peanut loves gravy so I added water and mixed it well. He gobbled it down. He's only nine pounds and only eats once a day. It helped with his bitting at his tail and scratching.

    My grandson's dog stayed with us five days and she was a picky eater so I put some on her food and she gobbled it down in no time. I'm so glad I discovered this amazing product that will help Peanut Butter get the nutrients he needs.

    Bottom Line: Yes, I would recommend this to a friend

    Nutri Thrive works well!

    • Aug 19, 2019
    • Verified Reviewer

    I have an approximately 8-year-old Mixed breed Chihuahua and Jack Russell Terrier. We drove 200 miles to pick up a Chihuahua and out came Milo...we looked at each other and said that’s not a Chihuahua? But he was so cute, he was white with brown spots and a million black freckles under his white fur. We were afraid if we didn’t take him nobody would cause he was a mixed breed, he had a Chihuahua face and a Jack Russell body. Anyway, he had been eating a lot of grass and his stools would sometimes be really soft then formed, and he didn’t seem to have as much energy. I saw Nutra Thrive and decided to try it. Well, first he stuck his nose up at his food bowl, he reared his head back and looked at me as if to say "what the heck is this stuff?", and I really mixed it well so there was no hint of powder. Finally I decided to sprinkle some mixed shredded cheese on it, not a lot, well he gulped it down, and even licked the bowl.

    No more eating grass, no more stinky gas, stools are formed, and he seems like he has more energy, but he has only been on it for two weeks.

    My complaint was when I opened the jar it only looked 3/4 full. I feel sorry for people with more than 1 dog or big dogs. I’m on disability after being a Registered Nurse for almost 40 years. The disability doesn’t come close to what I used to get paid. I have had 5 mini-strokes, and I have an immune disease where I don’t make my own antibodies anymore. So I have to get an IV infusion once a month to the tune of $4,000.00. The price of $49.99 was a lot for me, but I just cut some things out. I don’t know how I’m going to manage almost $ 70, I take a lot of medications, my copay for my eye drops alone is $100. But I love my dog he is my constant companion and protector, since I hardly go out so I don’t expose myself to other people’s germs, because they will make me sick.

    I definitely would recommend Nutra Thrive, like I said, my only complaints were I wish the jar was full, and not so expensive. Elderly people who are on social security would definitely not be able to afford this. I just hope I’m able to afford another jar when this one is running out.

    If your dog is having digestive problems, lack of energy, Nutra Thrive will definitely help, among other things.

    Thank you.

    Made my dog sick!

    • Fort Worth, TX,
    • Aug 16, 2019
    • Verified Reviewer

    I'd like to send the product back for a full refund. Please provide instructions to do so. I bought Nutra Thrive on 7/14 for my 15-year-old Shih Tzu/terrier mix. After I started adding it to his food, he started throwing up every day. After a few days, I stopped using it, and the vomiting subsided. A week or two later, I was out of town for a few days, and my boyfriend, who was watching my dog, didn't realize I had stopped using Nutra Thrive. He added it to his food while I was out of town, and he vomited the day I came home. When I asked my boyfriend about it, he said he had vomited a few times while I was gone. I stopped the Nutra Thrive again, and the vomiting subsided. Although my dog is 15, he is very healthy and does not normally vomit. After it happened not only once, but twice, I was convinced it was the Nutra Thrive. Nothing else had changed.

    I tried to leave a negative review on the product website, and it wouldn't let me. Fishy! I would not recommend Nutra Thrive!

    This product does NOT work at all, do not waste your money! I had given it to both of my dogs for a month and saw no changes in their energy level, breath, or overall health.

      Hi Bertina, I’m Shayne with Ultimate Pet Nutrition. NutraThrive comes with 30 scoops per container. How long a jar lasts will depend on the size of the dog, as we recommend a higher dosage for dogs that weigh thirty pounds or more. Dogs of any age may use NutraThrive, and see optimal results following three months of consistent daily use. However, we always advise our customers to consult their pet’s veterinarian prior to making any changes to their pet’s daily regimen. You may find NutraThrive’s complete supplement ingredients and answers to frequently asked questions on the official NutraThrive page. Please feel free to email me at shayne@ultimatepetnutrition.com for more information or feedback. I wish you and your French bulldog a wonderful day.

    I have six dogs, so I ordered 3 tubs of Nutra Thrive to start. After about a week and a half (which was about 2/3's of the first tub), ALL SIX DOGS had loose stools. No other changes in Dog food...Orijen Dry, Canidae grain-free pure canned, and their freeze-dried liver treats. They do not get people food. So I contact the company for a refund. They offer a 90-day moneyback guarantee. They said you have to return the product for a refund, which is fine, except they only refund the unused portion. How does that work? This stuff made my dogs ILL. And with six dogs, it took most of a tub for that to become evident. SCAM company. I would NOT recommend this to anyone.

      Hi Tracy, I'm Shayne from Ultimate Pet Nutrition. I'm so sorry to hear about this upsetting experience. It sounds like your dogs might be experiencing "Die Off Symptoms", which occurs when introducing probiotics into one's system. In regards to our 90-Day Money Back Guarantee, we do typically ask that our customers send back the unused portions to ensure that they gave the product a fair try. I'm really sorry for the miscommunication. I checked our system and it looks like you were fully refunded. Please confirm this by e-mailing me at Shayne@ultimatepetnutrition.com. If you are still experiencing any outstanding issues, I can assist you right away. Again, I'm so sorry for this experience but thank you for giving Nutra Thrive a try.

    My cat had a GRD problem which I was giving her pills (that I had to force down her mouth). I started with Nutra Thrive and after 2 weeks she is doing great! She loves the taste. I am still buying a prescription diet cat food for sensitive stomach issues, but without the pills, she still threw up. With Nutra Thrive she is doing much better. And the diet food is cheaper than the off the shelf, high-quality cat food.

    I ordered Nutra Thrive for my schnauzer and my chihuahua. I had been looking for a product like this and after seeing the video, I knew I had to try it. My schnauzer weighs 20 lb and my chihuahua only 6 lbs. I have divided the dosage according to weight. All is going very well so far. The dogs are happy with the taste, and it appears that their "poops" have really improved.
