    Rated 5 out of 5 by from GREAT RESULTS! I have a 9 yr old mare ...never had any problems until early fall of 2015 after show season. I use her western pleasure and last year she started to show slight signs of allergies ...symptoms would come and go...wasn't too concerned until fall she broke out in HIVES! and for 5 months.Wanted to avoid steroids because of side effects...started to research ...ended up being stress..contacted smartpaks and they recommeded APF .shipping was quick and started the day i received supplement and within 2 days hives were GONE! I highly recommend this product for daily maintance for immune health and my mare seems more comfortable than before

    Rated 3 out of 5 by from No noticeable benefit My mare has allergies and PPID. I have been feeding APF for several months with the hope that it would provide additional support for her system. Unfortunately, I did not notice a difference while feeding this and she still gets hives despite being on a daily dose. It is too expensive to feed "just because." I am disappointed since my picky mare didn't mind the taste! I appreciate that SmartPak offered this on their SmartWafer - my horse always ate it!

    Rated 4 out of 5 by from Great Product The product is easy to feed, the small amount of liquid soaks readily into thepellets and seems very palatable. My mare never hesitated to eat her ration, as per usual. She is doing well on it, seeming less concerned about cold and rain, environmental stressors that used to send her into shivers.I previously gave the same supplement to a rescue horse that had a breathing problem. It was miraculously "cured" with the APF Formula!

    Rated 5 out of 5 by from Really a miracle My mare suffers from hives every year starting in springtime. I gave up on the recommended vet medication years ago because the hives come right back after the course of treatment and the drugs are not good on an ongoing basis. I just got a bottle of APF last week and it really worked like a miracle. Whinny was covered in huge, oozing welts all over her barrel and chest. They went away literally overnight after the first day of using APF. I am a big skeptic and did not really believe the reviews, but now I'm a believer. If your horse has hives, this is the product to try first. I hope it works for your horse as well as it worked for mine!

    Rated 5 out of 5 by from Miracle worker! My Morgan gelding has suffered from horrible, oozing hives all over his body for over a year now - they appear out of nowhere, in every environment (hot/cold temperatures, indoors and outdoors, at home and at shows). We were never able to isolate the cause of the hives and were unable to find any relief for my gelding besides the usual pharmaceutical remedies (which aren't good in the long term). I came across APF while doing some online research on herbal remedies, hoping not to have to keep him on prescription drugs any longer. I ordered the recommended dosage on SmartPak wafers. My gelding's hives literally disappeared overnight and haven't returned since! His coat is shiny, his eyes are bright, his energy level is through the roof - he is the best possible version of himself, even after lowering the dose a bit for cost savings. I would recommend this product to anyone!

    Rated 5 out of 5 by from This stuff is fantastic! I started my horse on this in the spring because I read that it might help with anhidrosis. He had an injury early in the summer and was on stall rest for the month of July and was just walking for the month of August. He has not lost muscle or much topline and looks fantastic for a horse that spent 60 days basically doing nothing. My friends horse spent some time on stall rest over the spring and did not look anywhere as good as mine. They are both older TBs. I definitely believe the APF is the reason my horse looks so good. He's also been sweating pretty normally all summer.

    Rated 5 out of 5 by from incredible My Morgan picked up a bad tick while showing and came down with a severe case of Lyme Disease. He was at the "help him or put him down" stage. I was looking for anything, and I mean anything, that might help. I already had him on Smartpaks so I decided to try APF. That was 5 years ago. At first I thought the Lyme flare ups that happened when I ran out of the product were just a coincidence. Nope. Now I keep my boy on this product daily without fail. I even keep spare bottles at home in case the barn's bottle is out. Seriously. While it didn't cure the Lyme (nothing did, not even 3 weeks in intensive care on IV antibiotics) I believe it helps prevent the flareups that endanger his well being. Incredible stuff.

    Rated 5 out of 5 by from Life saver! My OTTB has a long list of medical problems--founder, laminitis, club feet and arthritis just to name a few--and then last April, he started developing hives. At first we chalked it up to the changing season, pollens, flies, etc., but no matter what we did the hives remained. I had lots of expensive allergy testing done that was inconclusive, and he was on a series of different allergy medications with no success. By December, he STILL had the hives, and had also become very listless and depressed, and I feared we were nearing the end.As a last ditch effort I called Smartpak and asked to speak to a supplement specialist, and the lovely lady I spoke with suggested APF. Within DAYS the hives were almost gone, and within in a week he was hive free. He also perked up and is back to his normal personality, and has been consistently sound since he started APF. He has been on it for nearly 6 weeks now, and the hives have not returned.I am extremely impressed with this supplement---it may have saved my horse's life!

    Rated 5 out of 5 by from Surprising results! I tried SmartBreathe for my poor IR guy who has allergy issues which cause labored breathing and runny eyes when it is hot and humid but sadly it caused stomach upset. In desperation, I spoke with a representative who suggested I try this, so I did. Within a week I noticed his breathing was significantly improved. What I wasn't expecting was that the scratches I had been fighting for 8 months were clearing and he wasn't as itchy all over. His eyes stopped watering too. The giant scabs from scratches that I had tried nearly every product known to man daily, were going away and healthy skin was appearing. Great surprise! He loves the cookie form. I love the results so much I added these to the SmartPak of my other horse. I wish I had known to try this sooner. They seem to work for everything that ails you. Maybe I should start eating them myself. :)

    Rated 3 out of 5 by from It's ok I think, for us, this works better as something to use before travel than for general health. My 11 year old guy is recovering from EPM, and I haven't noticed that it's helped him regain weight or muscle better than without. I've been using it for about 2 months now. It might be a better product if your horse has other reasons for weight loss and muscle ataxia.

    Rated 4 out of 5 by from Great to help with stress I heard about this product on the Yahoo Cushings group, as a way to help horses deal with stress (medication, moving, injuries, etc) and tried it on my mare during a recent stressful move. She seemed to handle things more calmly than previously, and she just gobbled it right up. Seems like a great product to have on hand.

    Rated 5 out of 5 by from Greatcwaybtobadminister APF I like the wafer for administering the APF, so much easier than drops which can get over done. Cost is still pricey, but that is because of the overall APF cost, not what Smart Pak has done.

    Rated 3 out of 5 by from 118 days? No way! I haven't given this to my horse long enough to know how well it works. It does seem to be quite palitable. However, I don't know where they came up with a bottle lasting 118 days. Recommended dosage on the label is 4 to 6 ml per 1,000 lbs. for a horse in light work and 6 to 10 ml for a horse in moderate to heavy use or if you are treating for an illness. By my way of thinking, a bottle will last only a month. Pretty expensive! I hope it works. I will have to come back and adjust the star rating if I see good results.

    Rated 5 out of 5 by from One of the best supplement investments This supplement has been an absolute lifesaver for me. I have had my horse for the past 10 years and over the past 3 years, he has had some trouble with skin conditions, especially scratches. I had been battling a horrible case of scratches since October of 2011. I tried pretty much every topical I could think of, used proper management for cleaning, etc and they wouldn't improve. Since scratches can be related to a weakened immune system, I decided what better way to help support him there than with this supplement. I started to do 4ml a day on a SmartWafer and within a week and a half, his scratches are 75% gone. I absolutely attribute this to the APF. And, on top of it, my horse LOVES the way it tastes. Win, Win!

    Rated 4 out of 5 by from change for the better Since I started my 21 year old Cushings mare on APF (on Smartwafers) about two months ago, I have seen some positive changes. Her coat is smoother and shinier. Her attitude seems less grumpy, and she is arguing less with the gelding stalled next to her. I would say she is both more mellow and more energetic. She thought the Smartwafers tasted weird at first (much head-shaking and mouth-gaping) but after a couple of times, she started looking for them. I started seeing the more positive attitude after only a couple of days on the APF. So I will be feeding it as long as I can afford it.
