ENDLESS ITCHING IMPROVEMENT

We were at our wits end. Did not want to give shots or rx drugs that have very bad side effects. Thor has been on interstellar for a month and has improved by 80%. Seeing his personality and able to snuggle again.

Thank you so much for making a product that works, not just to get people's money.

WORTH EVERY PENNY

I have four dogs and my French bulldog licks his paws constantly. So far the licking has improved. My other three dogs have stomach issues off and on and so far loose stools have improved greatly. We have been using the product for almost two months and are happy with the results. We would recommend this product. Allergies also seem to have improved.

Why should I use Inner Stellar?
  • Today more than ever, dogs are suffering from immune-related issues like itching.  What most consumers don’t realize is that surface-level issues like itching are actually a sign of inflammation within.
  • Itchy dogs have a lack of indoles, natural anti-inflammatories produced during healthy digestion. This indole gap leads to inflammation, and visible discomfort and itching
    on the skin.
  • Inner Stellar is the first pet supplement designed to tackle itching at its source by providing these missing indoles. It’s clinically shown to dramatically reduce itching, improve skin and coat quality, and promote gut health in just 14 days.
When will I notice a difference?
  • In a clinical trial, daily use of Inner Stellar’s postbiotic led to significant differences in itching, skin health, and gut health starting at just 14 days.  Every dog is different, but most dogs will show visible improvements before your first jar is empty if you give
    Inner Stellar to your dog every day.
  • To maintain those results, it’s important that you keep the daily routine going and ensure your dog receives a steady supply of indoles.  Once dosing stops, indole levels decline and old patterns return.  Make Inner Stellar a part of your dog’s daily routine, and the improvements you see will become their new normal.
  • We offer discounted subscriptions on Inner Stellar to make sure you never miss a day.
How easy is it to use?
  • Just add the recommended daily dose (split half in AM, half in PM) to your dog’s daily diet to keep indole levels steady and maximize results. Consistently using the product each day is the most important thing!
What ingredients are used?
  • Our team of PhD microbiologists hand-selected each ingredient in Inner Stellar to deliver missing indoles directly to the gut (through the indole postbiotic), spark ongoing indole production over time (through the indole probiotic), and help your dog to absorb the indoles fully (with the indole support blend).
  • We only use premium human-grade ingredients, with no artificial flavors or colors, and even our beef liver powder is grass-fed.
  • We’re raising the bar on pet supplement standards by ensuring that every lot of Inner Stellar is third-party tested for purity, potency, and safety.
Are there any side effects?
  • Like any change in your dog’s diet, starting Inner Stellar might come with a short adjustment period. Some dogs may experience mild digestive upset, or temporary changes in bowel movement.
  • But here’s the good news: that’s actually a sign it’s working. Inner Stellar is designed
    to interact with your dog’s gut microbiome - and those early changes are often just your dog getting used to the new support. Any mild digestive responses usually resolve within a few weeks of regular use.
  • To keep indole levels steady and maximize results, we recommend splitting the daily dose (half in AM, half in PM). To ease in to the transition:
  • Days 1-3: Just give the AM half-dose
  • Day 4 onward: If things look good, proceed with adding in the PM half-dose as well.
What age does it work for?
  • Inner Stellar is meant for dogs of all ages, sizes, and breeds, though we recommend starting its use only after your dog is at least 3 months old.
