Is this to be used in place of the calming pellets or with???? I am also using the Wellness.

Asked by: Trish
Hello, The calming supplement does already contain Thiamine (B-1). We would suggest consulting with a veterinarian before supplementing additional B-1 to your horse. Thank you, SCAH

why does it need to be discontinued 7 days prior to a show?

Asked by: Fenn
Hello, We have no warnings listed on our website in regards to discontinuing use 7 days prior to showing. If this has been read on a show regulation page then you would need to reach out that committee in regards to their showing rules. Thank you, SCAHealth

Rated 5 out of 5 by from From Wild to MildSince starting my mustang filly on Vitamin B-1, I have noticed a definite difference in her overall relaxation and ability to handle once potentially scary situations in a much calmer and less reactive manner. I had been feeding raspberry leaf daily with questionable results. Since I started feeding her the Vitamin B-1, there has been no question about its effect. Definitely a much easier-going horse. Although I'm sure maturity and groundwork contribute to her increasingly calm demeanor, I am convinced that feeding daily Vitamin B-1 has been a big part in making her a fantastic partner. It's an inexpensive and safe way to help her become the horse I know that she can be.

Rated 5 out of 5 by from Great product!I have been giving my QH mare Vitamin B-1 Supplement for a few years. I started when she suddenly went into heat after years of apparently not doing so. When I moved her to a new facility I gave it to her starting a few days before the move. In both cases it helped her stay calm and adjust. After the move I have kept giving it to her daily. It helps her with the day-to-day stresses of sharing a pasture and barn with 5 geldings and when horses have moved in or out of the barn. Although she is a steady horse by nature, she does have some "interpersonal skill" problems (mare!) and this seems to help her a lot. I highly recommend it.

Rated 5 out of 5 by from Excellent supplementI bought this about a month ago for three of my horses that have issues with anxiety and focusing during competition. I have been very happy that all three of them are more relaxed, less reactive, and more focused while performing in the ring and during training sessions. They are a Morgan, a former racing Quarter Horse and a thoroughbred.

Rated 5 out of 5 by from Good price, horse eats itI bought this to add with the magnesium supplement I also purchased. It has worked well in combination with the magnesium to help my horse calm down. He was piaffeing in the stall and would explode out of the stall when I was turning him out. After being on this and the mag at the recommended dose, he was said to be like a "normal" horse when his stall got cleaned after being stuck inside for 2 days because of snow and ice outside. Definitely will keep him on this. The price can't be beat and the pelleted product is the way to go.

Rated 5 out of 5 by from Improves focusI wanted to help my horse stay focused but I did not want to give him a calming supplement. UltraCruz B-1 was the right choice for me. It is only B-1 so it contains none of the calming ingredients I don't want. It comes in a palatable pellet and is easy to feed. Best of all, it has really improved my horse's focus!
