    D-Carb Balance is rated 4.7 out of 5 by 63.
    Rated 5 out of 5 by from Great for insulin resistence horses I have been using this product for several years and the price at SmartPak was below what I could have purchased locally.

    Rated 5 out of 5 by from great multi-vitamin for my easy keeper I started my 13 yr old easy keeper mare on D-Carb Balance after trying Quiessence and SmartControl IR. None of the products have helped manage her weight, but after being on D-Carb Balance for a week, she showed a marked improvement in her coat condition (even after being on Farrier's Formula Double Strength for many years) and attitude. I would highly recommend this product for any horse not receiving a full portion of vitamins/minerals through grain and forage. She'll be on this product for the rest of her life!

    Rated 5 out of 5 by from Tasty Supplement My horse is not a picky eater but he cleans up every last bit of this supplement. My horse has HYPP so I like that this supplement doesn't have potassium in it. It's nice to not have to worry about adding potassium to his diet but still allowing him to get his vitamins & minerals since he only gets oats and grass hay.

Equine polysaccharide storage myopathy (EPSM) ,Hyperkalemic periodic paralysis (HYPP), and non sweater. All three horses got this vitiman with whole oats.

    Rated 3 out of 5 by from No Real Change Noticed I haven't really noticed a change in my horse since starting him on the D Carb. I am going to try a few feeding changes and see if that helps. Just can't see spending this kind of money on something with no positive results.Yeah, my horse eats it.... but we're talking about a horse that eats anything!!! That's his problem to begin with!!!!

    Rated 5 out of 5 by from Great Product My moms horse has the beginnings of cushings and has recently foundered. Our vet recommended this product and it has helped tons. She has her old energy back, a beautiful coat and we are no longer having overweight problems with her.

    Rated 2 out of 5 by from Horse Stopped Eating It My horse ate it for a few weeks and then stopped and refused his grain. He is a bit of a picky eater, and I've had trouble getting him to eat IR supplements. I would also like to see the chromium at a bit higher level.

    Rated 5 out of 5 by from Great Product Done amazing things for our mustang that seems to smell food & get fat. She will always be a plump girl but her weight seems to have redistributed and her cresty neck has gone down. She eats this right up. We tried changing her to SmartPaks version & she wouldn't touch it. but of course Smartpak took care of that with their excellent customer service :)

    Rated 4 out of 5 by from your changes I was informed that your products makeup had changed. It smells different looks different and my horse refused to eat it. Hopefully it will work as well as your other product. It took some creative planning to cover it up in his feed. So far it has worked. He does eat it. What changed?

    Rated 5 out of 5 by from Does the trick! My IR/PSSM horse had trouble maintaining his weight on ration balancers (he also gets magnesium, chaste tree berry and vitamin E, along with grass hay and pasture), but with D-Carb Balance (and his other supplements) he dropped the fatty pockets around his tail, withers, and the cresty neck within the first month of being on this supplement. He has a lot more energy too!

    Date published: 2011-08-05
    Rated 5 out of 5 by from It has worked so far! I have a cresty, hungry, chubby Paso Fino mare who, by appearance alone, is metabolically challenged. I have fed her D-Carb for about 3 years. I supplement it in the summer with chromium powder from my vet and I muzzle her in the spring and when she is out on my good pasture all day. She has not foundered, been in good health, unshod, with shiny coat and a good attitude.
    Date published: 2011-05-30
    Rated 5 out of 5 by from Definitely works My mare has problems with her sugar levels and the magnesium supplement I'd been using for several years suddenly stopped working. She got a cresty neck and started throwing shoes. So, after doing more research thought this product sounded very complete. After nearly a month, I can see a huge change. She is much much more relaxed and her hooves are nice and solid. I am very pleased.

    Rated 5 out of 5 by from D-Carb balance My vet recommended we try this product, he hasn't been on it for long, but he seems to be doing well. He was on Uckele products for his IR and cushings, but this product is just one product with the same ingredients as their two and with vitamins added which he didn't get in those.

    Rated 5 out of 5 by from Very helpfull at keeping the weight off The d carb balance seems to have really helped keep the weight down on my rockymountain/welsh cross that was getting real cresty. She also had deposits of fat above her tail. Since using the dcarb balance she has come down in weight slowly but it appears to be keeping her from gaining it back.

    Rated 5 out of 5 by from D-Carb Balance Ever since I started using this product, Pork Chop has not foundered and has been "healthy as a horse". He is 30 years old and loving every minute of it.

    Rated 5 out of 5 by from Keeps Paso mare well I don't know if this works, I only know my EASY keeper little Paso Fino mare has not had any trouble with her hooves or anything related to metabolic syndrome. She is round, cresty and hungry and I try to keep her off green grass. She gets no grain, only soaked beet pulp with one alfalfa cube twice a day with her scoop of D-Carb and she a healthy horse.

    Rated 5 out of 5 by from my horse likes it I ordered this after researching other products and decided on this one as it had added electrolytes and was less expensive then my vets recomendation. He agreed that it was a good value. My horse ate it from the first serving.

    Rated 5 out of 5 by from Great Product for Easy Keepers! My easy keeping Paso Fino used to have fat pockets on his body. With D-carb balance, he is trim and fit, and still gets his vitamins!

    Rated 5 out of 5 by from D-Carb Balance I have a 9 year old mare that is truly a best friend. She can look at food and gain weight. I have tried every product made to help her and D-Carb Balance has made the most difference for her without putting her in "race" mode. She looks better and feels better with this product.Thank you!Judy

    Rated 5 out of 5 by from It seems to actually work! My easy keeper nearly foundered on spring grass this year. We started her on D-Carb this past month and she is now back to her old self!

    Rated 5 out of 5 by from Melting Away! After years of keeping my lamnitic mare on dry lot with no results, I began D-Carb by recomendation from my veterinarian. Within a month, most of her fatty deposits in her lower abdomen and neck began to disappear. Now, she is almost a completely different horse, more energy and love for her work. My mare is also loving her new grazing privilege with a muzzle. I never thought one supplement would solve her problem!
    Date published: 2010-06-15
    Rated 5 out of 5 by from Great help for foundered ponies! D-Carb has helped a particularly hard chronic-founder case recover quicker. This is great for horses with metabolic problems. The cresty necks, lumpy withers and rumps, despite strict diets; those horses do great on this! It really helps minimize dietary distress. I'm a barefoot trimmer in the midwest and have recommended this to several people with chronic horses.

    Rated 2 out of 5 by from Glutton pony wouldn't eat it I started our new pony on this product after checking all the reviews for metabolic supplements and reading about the condition. He ate it for about a month somewhat reluctantly, then stopped eating it at all. This pony is a serious glutton and got no grain. This is all he had in his feed tub each day but he would not eat it.While he would eat it we saw good improvement in reducing the fatty deposits all along his neck and tailhead, so it was disappointing that he stopped eating it. I switched him to SmartControl IR pellets, and he likes those!
    Date published: 2010-04-21
    Rated 5 out of 5 by from Great Quality I was very surprised the quality and effectiveness of this supplement for the price. My horse has had laminitis for three years now and on this supplement she is not as sore, able to eat small amounts of grass, and the weight I thought she was destined to keep is slowly falling off! I am so happy to have found this supplement as it is not available in my area.
