Q: What does the Breathe Easy Bundle help with? A: This bundle supports pets struggling with respiratory stress — from occasional coughing to deeper breathing troubles. It helps soothe irritation, strengthens the immune system, and promotes easier breathing so your pet can rest and recover naturally. Gentle, effective, and safe for both dogs and cats.

Q: How does the Breathe Easy Bundle work? A: It combines the oxygen-based immune support of Ox-E Drops with the antioxidant-rich nutrition of Nzymes® Antioxidant Treats. Together, they help the body manage oxidative stress, calm irritation, and support clearer airways and stronger natural defense — with all-natural ingredients.

Q: When will I see results, and how do I use the products? A: Many families notice signs of relief within the first week, such as easier breathing, improved comfort, and more restful sleep. For pets with deeper or long-term respiratory troubles, consistent daily use brings continued improvement. Each kit includes a downloadable PDF with clear usage instructions, and our team is always here to help — by phone, email, or live chat.

Antioxidant Treats (or Tiny Treats): Made with sprouted soy, stabilized rice bran, selenium, defatted beef liver, and natural vitamins A, C, and E. These enzyme-rich treats provide antioxidant support to help maintain healthy joints, skin, neurological function, and immune balance. Designed to promote vitality, mobility, and recovery from oxidative stress—naturally and safely.

Ox-E Drops: A natural liquid supplement made with stabilized oxygen and purified water. When added to your pet’s food or water, it helps increase oxygen flow, support the immune system, and fight harmful buildup in the body. It can also be used for gentle topical or vapor support when needed.

The Core Foundation is our complete enzyme restoration system for dogs of all ages. It combines two powerful, natural formulas — Sprouted Granules and Antioxidant Treats — to help replenish enzyme levels lost from processed food diets.

This foundational system supports your dog’s natural cellular processes, helping their body maintain strength, mobility, digestion, skin health, energy, and overall vitality.

What’s included:

Sprouted Granules (daily enzyme-rich topper)
Antioxidant Treats (chewable enzyme support)

Safe for: puppies, adults, seniors, small breeds, large breeds, and sensitive dogs.

Sprouted Granules

Live, active sprouted soy
Natural plant-based enzymes
Essential amino acids
Antioxidant compounds from whole-food sprouts

Antioxidant Treats

Live-sprouted base (same as Granules)
Natural plant antioxidants
Nutrient-rich whole-food ingredients
Cold-processed formula to protect enzyme activity

All ingredients are non-GMO, naturally sourced, and minimally processed to preserve enzyme activity.

Step 1: Add Sprouted Granules once daily Sprinkle the recommended amount over your dog’s regular food. Start with a small portion and gradually increase over 3–5 days.

Step 2: Give Antioxidant Treats daily Use as a daily chew. You may give them with meals, as a reward, or split the amount throughout the day.

Daily use is important. Enzymes work best when given consistently so your dog’s body can maintain healthy enzyme levels and support everyday functions.

For best results: Use both products together and allow at least 4–6 weeks of consistent use.

Most dogs grow up on processed food diets that contain no natural enzymes, which can leave their bodies working harder than they should.

Nzymes restores what processed food takes away.

Here’s what makes us different:

Live, active enzymes preserved through gentle sprouting and cold-processing
Whole-food based formulas, not synthetic supplements
Backed by 25+ years of real results from pet owners across the country
Designed for foundational health, not a quick fix
Works with your dog’s natural biology instead of covering symptoms

Nzymes isn’t just a supplement — it’s the missing nutrition your dog was meant to have from the start.

Your Dog’s Struggle Matters.

When your dog is coughing, hacking, or struggling to breathe comfortably, it can feel scary and overwhelming. You’re not alone and there are gentle, natural ways to support clear airways and keep your dog more comfortable as they recover.

What’s Really Happening

With Kennel Cough

Airways get irritated, and the immune system works overtime to keep things clear.

Coughing, gagging, and restlessness show your dog is struggling to breathe comfortably.

How Daily Support Helps Your Dog Breathe Easier

Supports clear, open airways for more comfortable daily breathing.

Eases irritation & discomfort so coughing and gagging naturally calm down.

Promotes long-term respiratory wellness to help your dog stay comfortable between flare-ups.

Corinna’s Dog

L. Swanson • Champlin, MN

Verified Purchase

When Corinna first reached out, her dog had been struggling with lingering respiratory symptoms that the vet insisted would require surgery to resolve. His breathing sounded congested, his eye appeared irritated from constant drainage, and nothing she tried seemed to offer real relief. Every day, she worried things were getting worse.

After starting the Nzymes Breathe Easy Bundle, the changes were almost immediate. Within days, his breathing became clearer and calmer. By the third week, the eye discharge was gone, the irritation had stopped, and he finally looked comfortable again. With daily use, his coat became shinier, his eyes brightened, and his overall health noticeably improved.

“Within days I saw changes. By week three his eye was completely clear, his breathing was better, and overall he was in better health.”

Before:

Congested breathing

Irritated, draining eye

Low overall vitality

After:

Breathing improved

Eye cleared fully

Health thriving again

Thousands of dogs with rear leg weakness have experienced life-changing transformations

Scott’s Huskies

Siberian Huskies • USA

Before:

“Scott’s four Huskies were constantly scratching, chewing on their paws, and dealing with stubborn bad breath. No matter what he tried, the irritation kept coming back and all four dogs seemed uncomfortable every day.”

After:

“After starting Nzymes, all four Huskies stopped the scratching and paw-chewing, and their breath became fresh again. Their skin settled, their coats improved, and they’re now happier, calmer, and enjoying life again.”

“Life for them now rocks! Happy Huskies!”

K. Kramer’s Puppy

Chihuahua/Doxie Mix • USA

Before:

K. Kramer adopted her tiny puppy from a local shelter and quickly noticed nonstop coughing that didn’t improve, even after antibiotics. The puppy struggled to breathe comfortably, and nothing she tried seemed to calm the cough.

After:

After starting the Nzymes Respiratory Support Program, the change was almost immediate. Within 12 hours the coughing eased, and by day three it was nearly gone. Her puppy was finally resting, breathing normally, and acting like herself again.

“By the third day, her cough was totally gone. I couldn’t believe how fast she improved.”

Gracie

Cavalier King Charles Spaniel • Santa Rosa, CA

Before:

When Penny was adopted, she was already struggling with kennel cough that quickly turned severe. She had trouble breathing, low energy, and thick mucus that made every breath difficult.

After:

Penny began breathing more comfortably and developed a strong productive cough that helped clear her lungs. By the end of the week, her energy returned, the wheezing stopped, and she was acting like a normal, playful young dog again.

“I never thought we’d see her recover this well. Nzymes helped Penny come back from a very serious place — she’s a totally different dog now.”

Rosie’s

Dachshund Puppy • IL, USA

Before:

Battling stubborn kennel cough, constant coughing fits, and lingering respiratory issues even after multiple rounds of antibiotics.

After:

Rosie’s cough began to ease and her breathing became clearer. She gradually regained her energy, started eating better, and is now acting like a happy, healthy puppy again.

"I’m so grateful we found Nzymes. Rosie’s cough is gone and she finally feels like herself again."

Everything you need to know about enzyme restoration.

Every dog is different, but most pet parents report noticeable changes within 2–4 weeks of consistent use. Some dogs with mobility issues, low energy, or digestive struggles may take 6–8 weeks as their enzyme levels replenish.Daily use is important — enzyme restoration works best when given consistently.

Yes — the Core Foundation is commonly used by senior dogs experiencing mobility loss, hind-leg weakness, stiffness, low energy, or digestive trouble.Because the formulas support natural cellular functions, they are gentle and safe for older dogs when used as directed. Always consult your veterinarian if your dog has underlying medical conditions.

Yes — the Core Foundation can be used alongside most medications and vet-prescribed diets because it supports your dog’s natural processes rather than interfering with them.For peace of mind, we recommend sharing the ingredient list with your veterinarian, especially if your dog is taking medications for seizures, inflammation, digestion, or mobility issues.

The Core Foundation is designed to support natural processes that influence strength, mobility, joint comfort, energy, and overall movement.While it does not diagnose or treat medical conditions, many pet parents use it to support dogs experiencing hind-leg weakness, stiffness, difficulty standing up, or age-related mobility changes.

Most dogs benefit from continued daily use, especially if they’ve eaten processed kibble diets for many years.Enzyme levels naturally decline over time, so ongoing support helps maintain mobility, digestion, energy, skin health, and overall vitality.Many pet parents choose to make the Core Foundation part of their dog’s long-term wellness routine.
