Omg !! After talking to Ron regarding my ex racer who was showing signs of being extremely uncomfortable & having probable signs of ulcers, he recommended Preulc powder before the Ulcex30. After a few days on the powder & before even using the liquid the difference has been so amazing that I sent Ron the before & after videos for his Facebook page! I’m a complete convert & will use his products forever! He also sent me Remount & Elastin to try free of charge & my horse is so chilled, happy & contented! Thank you again!

I have used this for a girths mare who had strong acidic wee. Really helps and my paddock now has no bald patches. Now moving to the next ulc step.

I am a vet and have used many of Ron Fields products. I have found them all to be amazing. Ron is very helpful and knowledgeable and always has time to chat to people about their horses. The pre ulcer powder is remarkable, it quickly and reliably relieves symptoms of ulcers and I find it incredibly useful as a diagnostic aid. I have used it in several horses with suspected ulcers and found it to help symptoms after only Afew days. This is then followed by ulcer x plus to help heal the ulcers.

My goodness – I can ‘hand on heart’ say that this works as I had my horse scoped today and have seen for myself what Pre ULC can do. There was clear evidence of ulcers up until very recently, however the area has freshly healed (within the last 3 weeks my vet estimated). The only change I made is the Pre Ulcer treatment. I only had him scoped for my own peace of mind tbh. I will keep my boy on ulcer x plus to keep them at bay and also am now keen to try the Elastin to keep his joints in good condition too. I will not feed my horses any other products from now on as I know they actually work. I have spent a small fortune on supplements and herbs over the years. Just brilliant to see there are alternative therapies that do what they say. Thank you so much Ron and your brilliant team.

Started our new boy on these supplements back in November few tweaks and he went to his 1st show jumping competition got a clear round but the difference in him was amazing. He was settled and even stood still in the collecting ring. I’m so pleased I found this page ( joe happy the boys face was yesterday)

“Wow!! Started using Pre-ulc on Friday with my horse who hates being being brushed and also having rugs on and off. I’ve tried to condense the videos so not too much footage but how is this even possible!!! First video Friday – second one today – Monday! What a difference already. I’m more than impressed. He didn’t even move to his stable door to windsuck once, let alone, kick, bite or pull faces. So happy!”

Following a course of antibiotics my horse was picking at his bucket feed and leaving most of it, so I suspected some gastro discomfort. I started him on Pre ULC, he ate most of his feed that day and seemed noticeably happier the next day, and by day three he was back to normal licking the bowl clean!

I’ve been using Ron Fields’ Pre-ULC powder on my quirky showjumping mare, who had a tough time recovering from lymphangitis. After prolonged antibiotics and Bute, she became unusually spooky, started rearing, and kept stopping in the ring – behaviours out of character for her. After discussing with Ron, we identified that she was likely dealing with hind gut ulcers, despite not displaying all the typical symptoms. Since starting her on the Pre-ULC powder, the transformation has been incredible. Within just a week, my mare’s attitude completely shifted – no more rearing, and she’s back to enjoying her work. She’s jumped twice since starting treatment and placed in the top 5 both times. Her mind is settled, and her performance is better than ever. Ron Fields’ Pre-ULC powder has made all the difference and I’m so greatful he’s helped me get my happy horse back
