This supplement is the best thing I've found to keep my senior ponies (22 and 34 year old) looking and feeling good, she went from looking like a bag of bones to actually keeping on her weight. She's still a little bit skinny but the difference pre supplement to now is staggering. It's been a little over a year, and she eats it in her mash no problem

Great supplement for our senior thoroughbred

Our 28 yo TB had been losing weight. Vet determined he had no health issues, dentist said his teeth were fine. We started him on this product and he has regained

Our 28 yo TB had been losing weight. Vet determined he had no health issues, dentist said his teeth were fine. We started him on this product and he has regained some weight even though it’s winter so no grazing available. He’ll celebrate his 28th birthday on Valentine’s Day

Excellent for older horses

I have a 33 yr old quarter horse who tends to lose weight during the winter. Weight accelerator is a wonderful addition to his feeding program. We give him 1 1/2

I have a 33 yr old quarter horse who tends to lose weight during the winter. Weight accelerator is a wonderful addition to his feeding program. We give him 1 1/2 scoop 2x daily. It is a amazing product. He eats it without any pro legs and in 2 weeks I have noticed him maintaining his weight. This has been such a blessing to our feeding program I have it on a monthly autoship.

31 yo TB race horse.

Have an old boy that is quite thin. Doctor said he just doesn’t absorb his food anymore. Teeth are fine and he eats non stop. I have been trying this product again

Have an old boy that is quite thin. Doctor said he just doesn’t absorb his food anymore. Teeth are fine and he eats non stop. I have been trying this product again for the last year and I guess it just won’t work on some horses. Especially like him. I keep trying though. His coat looks good. I’m sure a decision will need to be made soon. As long as he’s happy, I just let him be.

My horse looks great again - Highly Recommend

My horse lost weight last winter, as did a lot of the horses. Normally she gains weight back in spring, but she seemed to keep losing weight. The vet confirmed that

My horse lost weight last winter, as did a lot of the horses. Normally she gains weight back in spring, but she seemed to keep losing weight. The vet confirmed that physically everything was okay. She's 26 years old, so part of the issue is her age, but she has good teeth and no health issues other than arthritis. I tried other weight gain supplements (mostly oils) for about 5 months and she wasn't gaining weight. She refuses to eat her grain if a powder form supplement is added. So I was worried about this because it is sort of a powder (not a fine powder, but more the consistency of ground flax). Anyway, she ate it willingly in her grain. After only a month I started seeing the difference. After 3 months on this supplement, she looks fantastic. I started reducing the amount that I add to her grain, and will increase if it I need to going into winter. But she looks great and everyone at the barn has noticed that her coat also looks beautiful.

Flaxseed based

Being flaxseed based is a big plus. Other weight gain horse products are soy based. Flax is far superior with greater benefits.

It might work on other horses

I've used this product on a horse a few years ago and it seems to work. I bought this bag for another horse that could stand a few lbs. However, he's VERY picky

I've used this product on a horse a few years ago and it seems to work. I bought this bag for another horse that could stand a few lbs. However, he's VERY picky and wouldn't eat the feed with this supplement. Since I used two scoops, I'll just try to sell the rest via marketplace.

Good supplement

I thought this for my goats that need a little help through milking to maintain good show condition. I was mixed on product at first, my girls weren’t sure about

I thought this for my goats that need a little help through milking to maintain good show condition. I was mixed on product at first, my girls weren’t sure about it, but now seem to enjoy. I felt it did a good job with weight maintenance but not a great job. Would probably buy again, but not my first choice.

Life changing

My senior mare unexpectedly lost 200 pounds in a very short few weeks this spring for no known explanation. She always had a great appetite and had access to all

My senior mare unexpectedly lost 200 pounds in a very short few weeks this spring for no known explanation. She always had a great appetite and had access to all the food she could want. After many medical exams that gave no answers I tried Manna pro Weight accelerator. Within weeks, she gained back 95% of her weight and looks fantastic. I had tried other products with no success. I feared I was to put my horse down and now I know she’ll be around for another year and hopefully more. The high fat content seems to be the one thing more that she needed. I wish I had tried it sooner.

Love this!

My senior horses thrive on this supplement! I’m SO sad to see it being discontinued.
