APF - Advanced Protection Formula is rated 4.5 out of 5 by 83.
Rated 5 out of 5 by from APF gave me my horse back! My favorite horse, who is 19 this year, has had inflammatory issues most of his life, including mild to moderate heaves / allergies, borderline insulin resistance, and mild arthritis. The combo was enough to really limit what he could do. I wondered if he had some kind of immune issue going on. I had tried APF before without results, but now I think the dose just wasn't high enough then. For the past couple of years, every summer, he's had abscessed lymph nodes. The vet said it was allergy related and just to keep the drainage spot clean. I was desperate and put him on APF again with the most recent abscess to try to clear it up (2x the dose I did before). He ate the cookie happily. I noticed a difference in 3 days! He's been on APF nearly a month now. The swelling / lump under his skin is completely gone. Earlier this week he was running and playing the way he used to do when he was young. Today he cantered under saddle for the first time in five years and wanted to do more! I haven't had results even close to this with anything else. This stuff is expensive but it worked a miracle for me. I am going to do everything I can to make sure he stays on it!

Rated 5 out of 5 by from Double Benefit In December of 2018, we changed barns and I knew my cribber was going to spend more time in a stall, so I added 1ml liquid APF to his evening grain, on top of his powdered supplements. No problem with him eating it, but wasn't sure if it was helping much. Now summer, with the flies and heat, he usually gets hives and even more nervous cribbing. I started him on 2 ml 2 weeks ago, and NO more hives, plus he is quieter in his stall - cribs a few times, then relaxes. A definite change for the better! It's expensive, but it does the trick!

Rated 5 out of 5 by from Great product that works!!!! I purchased this product based on reviews stating it helped their horse with hives. I am pleased to report that only after 4 days of use my horse's hives are SIGNIFICANTLY reduced and the worst areas are healing nicely. I am happy that it worked for Ace and I will be adding it my monthly order.He also loves the wafer form as he thinks it's just another treat. I only wish now I had taken before photos to share. Thank you Smartpak!!!

Rated 4 out of 5 by from Palatable and easy to use I bought this for a horse with summer sores. He gobbles it up in some chafe hay and I expect he will stay on it until I know he is better.

Rated 5 out of 5 by from Great product I bought this for my horses conjunctivitis and it seemed to help. He also had something going on with his ho and I was having a hard time clearing it up until I start using the APF I will continue to use this I do think is helping his immune system

Rated 5 out of 5 by from Easy to feed. This cube is like a treat. My mare loved it. She quickly had fewer hives when other horses hives increased on a windy weekend. No way to prove if it was because of stronger immune system or a change in the season. She had lots of hives all spring so I wanted to give her a boost. Will definitely order this again next spring.

Rated 4 out of 5 by from good product I bought this product to support the immune system of my minis. I give it our normal size horses also. I believe it helps them should they get into a stressful situation.

Rated 2 out of 5 by from Not a good fit for my mare I've had her on this for two months now and I find It didn't do a whole lot for her. She has severe allergies, I was recommended this product and smart immune, both did nothing for her. May work better on a horse not so severe. I ended up seeing an allergy specialist.

Rated 4 out of 5 by from My horse is happier As my horse changed the barn, it is hard to say if this product is the 100% cause, but my horse is happier now. It seems that her chronic skin condition is improving, her focus is better, and in any event, she loves the muffin!

Rated 5 out of 5 by from Great for cellulitis My horse was quite prone to cellulitis, getting it several time a year. I started him on APF and, knock on wood, have not had a single case of it since and it has been over a year. I started with the high end of the dose recommendation and have weaned him down to 1 ml twice a day. I like the liquid as I can easily adjust the dosage if need be.
