Other Itch Supplements Mask Symptoms.
We Fix The Cause.
Scientific breakthrough on why dogs really itch:
Healthy dogs make natural anti-inflammatory compounds called indoles when they eat. These prevent itching.
But itchy dogs don’t make enough indoles. That’s the reason they keep scratching.
Inner Stellar™ is first to deliver the natural anti-inflammatory indoles your itchy dog is missing.
Vets Are Seeing The Difference
"I've evaluated many supplements claiming to reduce itching in dogs, and have found Inner Stellar to be the first of its kind."
Dr. Wendy Asato, DVM
"Inner Stellar is the first product to utilize nature's own anti-inflammatory indoles to address itching at its biological source."
Dr. Audrey Negrelli, DVM

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.

LESS ITCH
So I started slow like they suggested and I have noticed less itching as I got into doing it for a couple of weeks. I highly recommend this product.

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.
