FAQs

Questions pet parents ask before getting started

How long does it take to see results? +

Every pet is different, but many pet parents notice improvements within 2-30 days of consistent daily use. For deeper gut healing, immune balance, and long-term wellness support, we recommend giving the products at least 60–90 days.

Can I use this with my pet’s current food or medication? +

In most cases, yes. Myco Pet supplements are designed to work alongside your pet’s existing routine and can be mixed directly with food. We have not found any contraindications with medications. If your pet has a medical condition, we always recommend speaking with your veterinarian first.

Is this safe for both dogs and cats? +

Yes. All our products are formulated for both dogs and cats. Dosage is adjusted based on your pet’s weight and needs.

How do I serve the supplement? +

Simply mix the recommended amount into your pet’s food 1-2x daily. For sensitive pets, you can start with a smaller amount and gradually increase to the full serving over several days.

What if my pet is a picky eater? +

Many pets adjust easily when introduced slowly. Start with a smaller amount mixed into wet food, raw food, broth, or a favorite topper to help with acceptance.

Know that if they're a picky eater, this often is a sign that they have an imbalance in their gut microbiome. Try the Gut & Immunity+ supplement to help with this.

Also, our serving size is soooo tiny because we don't add any fillers, artificial ingredients or preservatives, so palatability is almost never an issue.

Can puppies and kittens use this? +

Yes, but we recommend using age-appropriate formulas like our Puppy & Kitten Formula when possible. Always follow serving guidelines based on age and size.

Do I need to use this every day? +

Consistency is key for the best results. Functional mushrooms, probiotics, prebiotics, and postbiotics work best when used daily to support long-term balance and resilience.

We always ask: if you feed your pet every day, they should also get gut supporting toppers to counteract the negative effects of the many toxins in our food system these days.

Is this a probiotic? +

All our supplements include 18 different species of probiotics, but it goes beyond that. Our formulas combine probiotics, prebiotics, postbiotics, functional mushrooms, colostrum and targeted nutrients to support the gut-immune axis and root-cause wellness.

What makes Myco Pet different from other pet supplements? +

We focus on root-cause wellness, not symptom masking. Our formulas combine functional mushrooms, probiotics, microbiome support, and human-grade ingredients designed to restore balance, strengthen immunity, and support whole-body vitality.

Can I use multiple Myco Pet products together? +

Yes. Many pet parents combine products depending on their pet’s needs. For example, Gut & Immunity+ pairs well with Lean Mass+ and the PROTECT Spray for both internal and external support.
