Smart & Simple® Vitamin B1 Pellets is rated 4.5 out of 5 by 143.
Rated 5 out of 5 by from Seriously amazing stuff! I’ve had my 11 year old Thoroughbred mare on this for almost two months now, and she is a completly different horse! I’ve tried some Calming supps. In the past and it was just too much. They made her so groggy. But B1 has been amazing! It helps put that busy busy mind at ease. My mare dosnt seem to get as restless in the stall, And is a dream to work now. Super focused and driven!!

Rated 5 out of 5 by from Great Product My horse has been in this product for a few years and it definitely helps maintain her calmness! Especially during the winter months.

Rated 5 out of 5 by from Works Great Been using B1/thiamine for nervous horses for years. Main ingredient in all the calming supplements, the ingredient that is most needed to balance the nervous system. Smartpak automatic ship makes it easy, and the paks convenient when you have employees setting up feed.

Rated 5 out of 5 by from Just what he needed Helped balance my geldings diet. With this and magnesium/chromium and smart thrive perform I don’t need further vitamin supplements. He was also noticeably more calm. For the winter I went one step further and upgraded to smart calm ultra so I don’t have to. It the magnesium separately.

Rated 5 out of 5 by from What a difference! I was skeptical when my friend recommended this product for my nervous and very hot thoroughbred mare. After less than a week of feeding B1 there was a marked improvement in her focus and temperament. She still has the same energy and "motor" but is now much happier to slow down, pause and think during her training, rather than just running through all my aids. I can once again look forward to riding my mare!

Rated 4 out of 5 by from Great product and easy to feed. I started my horse on this a month ago, and it seems to help him focus, however, I haven't taken him to a show yet, so will have to re-review again in a month.
Date published: 2017-07-17
Rated 5 out of 5 by from Perfect fit I've used B-1 with other horses with great success, so as my mare got more easily startled and harder to work with I started her on it. After a couple of weeks she's much more focused and calm.

Rated 5 out of 5 by from Hard to find product. I just found that you carried b1. I like the natural product.

Rated 4 out of 5 by from Works great My horse needs thiamine (B1) to keep focused and this does the trick for my picky eater; good product for the price
Date published: 2016-05-16
Rated 5 out of 5 by from Really works!!! This stuff really calmed down my horse during his stall rest.
Date published: 2016-04-06
Rated 3 out of 5 by from It was worth trying The pony has been on it for a month now and I'm not seeing any difference in her behavior, good or bad. She is still tense and unfocused. She gobbles it up so it's palatable and its good value. The trial and error experiment continues.

Rated 5 out of 5 by from Super focuser! I use this product in companion with Magnesium 5000 to obtain a fabulous focouser/calmant for my thoroughbreds and show horses. This combo is legal at shows and my horses are all calm and happy in the ring!
Date published: 2016-02-15
Rated 5 out of 5 by from great product! I started using this a month ago for my horse with string halt. I have seen a huge difference so far! I talked with a customer service rep and she reccomended vitamin B1 and the smart flex senior pellets, so far there has been a huge difference in his gait, and he doesn't aggressively slam his back hoof to the ground. Not only does smartpak have great product, their customer service is fantastic!

Rated 3 out of 5 by from Good Supplement I have been using Vitamin B1 for a couple of months now, but really see only a slight difference in my older horse's behavior. He is still a constant churner and has possibly slowed down a little bit. I will continue using it since I know it's good for him to take it, but it isn't a miracle fix.
Date published: 2015-11-09
Rated 5 out of 5 by from It works an picky eater approved! I have a 2 yr old who is a severe picky eater. This is her third supplement an the first she has continually ate it! And she is calmer overall!
Date published: 2015-08-05
Rated 4 out of 5 by from VVery palatable, gentle results This is a nice gentle change and I intend to continue use of it.
Date published: 2015-06-25
Rated 2 out of 5 by from My horse ate it, but couldn't tame a young mind. Good news: our mustang gelding LOVED it. Anything that is added to his grain ration he generally does though, so can't promise picky eaters will like it too. Bad news: it just could not help his young, easily distracted mind. He will be on it for two months and I took him off. There was ZERO difference in his behavior. It's telling me he didn't need this, and we will just have to work through the "terrible twos" with old school training and exposure alone.

Rated 5 out of 5 by from Awesome Product My horse has always been a little edgy and snorty on the ground. This product has helped to keep him grounded and has also helped with his performance.
Date published: 2015-05-07
Rated 5 out of 5 by from Finally Concentrating! I could not ask for a better supplement. Just after a month Kasey is not jumpy and is concentrating more in our workouts. More responsive and paying attention to me. She loves it and never leaves any behind.
Date published: 2015-05-04
Rated 5 out of 5 by from Works for my horse My boy has been on this for about a month and I have noticed a difference even with spring nipping on our heals. Can't wait to see what more time will do with this product. At the price it's worth a try!

Rated 5 out of 5 by from Works Great I bought this to help calm my eighteen year old Saddlebred mare that we just got back. I had her when she was four and had been a bit nervous and hot but not bad. Ended up getting her back after all these years as a rescue and she was a wreck. Used this to help her settle in and I have to say it works great. She has stopped pacing, has gained weight, and we are able to work with her to get her back on track. I recommend highly.

Rated 5 out of 5 by from Vitamin B1 Using this on my very nervous thoroughbred keeps him focused an has calmed him down good product
Date published: 2015-02-12
Rated 4 out of 5 by from Thiamine Supplement Wonderful aroma when canister is opened. Pelleted form mixes in nicely with pelleted feed to avoid sorting out or leaving a powdered product at bottom of feed bucket. Very dense pellet...... I soften ahead of time with a few sprinkles of water.
Date published: 2015-02-05
Rated 5 out of 5 by from Wonderful I got my gelding (who is 14 and very broke )in may he was just crazy adhd all over the place started giving this to him and now he is nice relaxed and pays more attention to me then what the other horse are doing.

Rated 5 out of 5 by from Works great, even for picky eaters! Really helped take the edge off for competition and daily riding.
Date published: 2014-11-10
Rated 3 out of 5 by from I have a 5 year old mare. She has only been on B1 for about 6 weeks. She seems to be paying attention more at horse show, not so distracted.
Date published: 2014-11-07
Rated 5 out of 5 by from Amazing results! I bought this originally for a project horse that had issues calming down and focusing in a busy indoor so my barn owner recommend this I gave it a try . It worked amazingly ! Now, I am still continuing the use of this supplement for my new horse just to give him extra concentration for showing and training.

Rated 5 out of 5 by from have used this product on many horses and just started it with a new horse and he is doing fantastic with it
Date published: 2014-08-02
Rated 1 out of 5 by from No difference Bought this product for my performance horse and haven't noticed any change. Still gets anxious and nervous at times. Looks like I'm going to have to switch products
Date published: 2014-07-31
Rated 5 out of 5 by from Great choice for picky eaters! Been feeding this to my ultra-picker TBx for 1.5 months & and he gobbles it up. With other brands he flat out refused to eat until he was served a new meal free of the "offending" substance. He does seem less hyper-reactive to changes in his environment (like a chair that has suddenly appeared next to the arena) and his general attitude seems better since I've been feeding the B1. The real test will be this Winter when we are stuck in the crowded indoor arena!
