Is it ok to use with digestive enzymes?
Answer by ChewyFeb 11, 2020
As digestive enzymes and probiotics have different functions within the body, they may be used together. Enzymes are proteins and probiotics are live organisms. That means enzymes can actually digest food and are effective at relieving common issues, including occasional gas, bloating, indigestion, heartburn and general discomfort. Probiotics, on the other hand, are useful in supporting overall health of the gastrointestinal tract as well as helping to support our immune system and the health of other body systems.

Good probiotic but my dog will not eat it alone

I like this probiotic because it contains many strains in comparison to other brands, and contains strains supposed to help with allergies. It's supposed to be odor and tasteless. However, my dog will not eat her kibble if I just sprinkle this on it. She will eat other probiotics like Purina Floritiflora just sprinkled on her regular food. To get her to eat this, I have to mix in broth or add a meal topper. She eats her kibble normally without any extras unless this is added on. The jar is very small. My dog is 42 lbs, and if I follow the instructions on the label I run through this pretty quickly. I wish it came in a larger jar.

Helped cat after antibiotics

Resolved foul diarrhea from antibiotics. It worked in a day or two, my cat maintained normal stool and I took him off this supplement after several weeks and the effect is lasting.

Paws down, vomit up!

I never have problems giving my cats probiotics. Heard good things about this one so I decided to try it out. Hard no from all 3 cats. They wouldn't go near the food, dry or wet. Finally they did start to eat some food that I put a bit in and they all started throwing up. They were not sick before they ate it. Starting throwing up and this was the only thing new that was introduced to them. They were better after a couple of days. Poor kitties, I told them I would not do that to them again.

Work Great!

Bought this for my 19 year old cat Charlie who has systemic yeast infection. He started having problems after his yearly vaccine. Apparently vaccines can lower immune response. The first thing i noticed was his fur starting to fall out. Then black on his ears and between his toes. I read that probiotics strengthen the immune system enabling the immune system to eliminate the yeast. Well, it's working great! Not only has Charlie's fur started growing back and the black fading, he's doing better than ever! It's a joy to see the old boy being more active and looking younger. He's been going up a 6' cat tree then vigorously scratching the post at the top. Our other cats are now getting the probiotic and there's a marked improvement in their health. They are more active, their fur looks great, they just seem happier. One thing I noticed immediately is all the cats really like the flavor. The devour anything we put it on. Dr. Mercola's Complete Probiotics is referred to as "magic dust" in our house.

Syringe with 1/4 tsp in water

This has saved many of my cats lives. When the vet says 'make them comfortable' he has done everything and it's up to you to give supportive care. The good bacteria helps the cats own immune system fight off bad bacteria and can be just enough to get them through rough times. Note this has S. Boulardii which tastes bad but is very important for intestinal health and can even fight Giardia which is difficult to treat. Stop crying about the missing spoon and taste. The exact amount is not important. Just mix a lil with water and use a syringe to drip into cats mouth. Pharmacys give out free syringes.

Great Probiotics!

My dog seems to be doing well on these probiotics, I like that there are many strains of them. His digestive system is much healthier than on other brands of probiotics.

This stuff works!

I had a very sick pup with diarrhea, hotspot, eye discharge, just not thriving. The vet gave us a probiotic that was basically brewers yeast. Trued thus and it was MAGIC! Pup is gaining weight and back to normal!

Dr. Mercola Probiotics

Not sure yet. It seems to be helping but I think I need to wait a bit to really know for sure.
