Kibble is cooked at very high heat so it survives on a shelf — but the live digestive enzymes and probiotic strains his stomach actually runs on don't survive that process. One scoop of VitaSmart puts them back, right on the food he's already eating.

What we add back
VitaSmart is the live layer kibble can't carry. 15+ probiotic strains for the gut microbiome. 20+ digestive enzymes that unlock the food he's eating. Whole-food vitamins from spinach, sweet potato, and blackberries — not synthetic isolates.
One scoop goes right on the food he's already eating. Nothing cooked out of it — so the probiotics and enzymes land in his bowl alive.
Why it matters
Commercial kibble is extruded — pressure-cooked, dried, bagged. The process is what lets a bag sit on a shelf for a year. It's also what strips out the live probiotics and digestive enzymes a sensitive stomach needs to run on. The food goes in. The tools the body uses to break it down didn't.
A synthetic vitamin spray gets added after cooking so the bag can say "complete and balanced." It isn't the same thing as real whole food with live enzymes and good bacteria still in it. For a dog with a touchy stomach, the difference is loose stool, grass-eating, bowl-walking, and the quiet daily work of a gut doing too much with too little.
You're not going to flip a switch tomorrow — the gut takes time to re-balance. But because the probiotics and enzymes work on the food he's already eating, most owners see something shift in days, not weeks.
What to expect
Most owners notice a calmer stomach within 5–14 days of daily use. The deeper gut-microbiome rebuild takes 90 days.

I heard about Ruff Greens by listening to Glenn Beck. I was hopeful it would help my little Gilbert with allergies. He's still a little itchy, but not as much. He used to eat grass a lot and that concerned me about how his tummy felt...

Dr. Black is a Naturopathic Doctor who spent decades studying how processed pet food fails the dogs it feeds. VitaSmart is the formula he built to fix it — whole-food nutrition designed to ride alongside whatever's already in your dog's bowl.
"A bag of kibble can hit every number on the chart and still be missing what a body actually lives on. The live cultures, the omega oils, the antioxidants — none of it survives the extruder. VitaSmart is what live nutrition looks like, added right back on top."

Most dogs do — VitaSmart is a whole-food topper, not a pill, and it goes right on the food they already eat. Some dogs with sensitive stomachs do best when we introduce it gradually: start with half a scoop for the first few days, then full scoop by day four or five. That gives the gut time to welcome the new probiotics and enzymes without a change-of-food reaction.
Commercial kibble is made through extrusion — pressure-cooked and dried at temperatures around 400°F so it's shelf-stable for a year or more. That heat is also fatal to the live digestive enzymes and probiotic cultures a stomach uses to actually process food. Manufacturers add a synthetic vitamin spray afterwards so the label can say "complete." What they don't add back — because they can't — is the live layer. That's what VitaSmart carries in, one scoop at a time.
Cancel within the 14-day window and no subscription charge ever hits your card. Everything you buy from us — the $14 trial and every subsequent subscription order — is also backed by our 90-day money-back guarantee.
