This high-quality weight gain supplement may be especially beneficial for horses participating in rigorous exercise or any horse that requires support to maintain a healthy body condition.

About Omega-3 Fatty Acids

Historically, under natural conditions, horses consume an approximately 5:1 ratio of Omega-3 to Omega-6, which is the ratio found in grass and green hay. The modern equine diet, which is primarily grain-based, has a low (less than 1:10) ratio of Omega-3 to Omega-6. UltraCruz® Equine Pure Flax Oil Supplement for Horses can help achieve the desired ratio of fatty acids in the diet to maintain balance and support horse health.

Rated 5 out of 5 by from Great even for picky eaters!After trying a slew of products to help a mare with an extensive medical history keep weight on her, UltaCruz Equine Weight Gain was recommended to us. This mare is a notoriously picky eater who will pick around supplements and refuse feed. When we added in the UC Weight Gain, it was the very first time in 3 years that we saw her eat with such a gusto that she did not even pick her head up out of the feed container! Already in almost 4 weeks we are noticing a difference in the amount of coverage along her topline and throughout her ribs, and we will definitely be continuing this product!

Rated 5 out of 5 by from Excellent product!!I imported a gelding from Germany in October and throughout his travels from Europe, to Florida and then finally home to Michigan at the beginning of this month. He had lost weight in quarantine and during his initial travels. While he began gaining weight in Florida, it was quite slow. I have had him on this product a few weeks here in Michigan and have already noticed him filling out nicely despite the cold and additional travel stress. The product seems to be very palatable and has a pleasant smell. I also like that this product does not contain hydrogenated fats, as some of the other weight building products do.

Rated 5 out of 5 by from The results speak for themselves!I've had my rescue horse on this product since I got him, when he came to me he was in quite poor condition. By adding this product to his daily feed as a source of extra calories, along with pasture etc. no one would ever believe that he came from a rescue or used to be underweight and in such poor condition! Really, really pleased with this product and am always recommending it to anyone looking for a safe effective way to put weight on their horse.

Rated 5 out of 5 by from Works wondersI bought this product about 3 months ago, i read that the product takes about a month to see results. So i decided to go out on a limb and buy the 128 day supply. I can say it was money well spent . My horse has shown amazing weight improvement ! He is an older horse and is very hard to keep weight on and this product is a life saver i am so happy with the results and will continute to use :)

Rated 5 out of 5 by from Fantastic Product at a Fantastic Value!Purchased for a late gestation broodmare to bump up her Omega 3 and Vitamin E levels, I'm a few weeks into giving her 2oz a day, I am very happy with this product!! I previously used a "name brand" oil known for it's Omega 3 and Vitamin E, but it was getting to be hard on the pocketbook, and to be honest, hard to get my mare to stay at her feed bucket! With UltraCruz's product, however, she has not ONCE turned her nose up due to taste or smell, she licks her bucket clean! ...and my wallet is VERY happy as well! We are still in the "winter woollies" here in Wisconsin, but she is shedding out quickly, and I'm excited to see a little bonus shine and condition on her soon :) I will be continuing to use this product! Thank you!

Rated 5 out of 5 by from Helped Older Gelding RecoverMy older gelding (25) went through a stressful move from one state to another. He quickly developed colitis/IBD, causing him to be very sick, and a three day stay in an equine hospital. After picking him up, I realized he had lost so much weight in a very short amount of time. The vet hospital recommended an oil supplement to help him regain some of his weight before winter. I am so glad I tried this, not only is he steadily gaining weight, but his coat looks so shiny too. I will likely keep him on a small dosage of this product even after he is back where he needs to be. Very happy with the results.

Rated 5 out of 5 by from When I bought My Lil Lucky DuckWhen I bought My Lil Lucky Duck as a three year old, he had a long dull coat and it was really hard to keep his weight up. He was in training for the fall cutting futurities and was getting ridden and worked often. After struggling for a year and a half trying to get him to hold his weight, a friend recommended UltraCruz Equine Weight Gain with vitamin E. Within a week there was a noticeable difference and he looks great! Not to mention he loves the taste!
