Excellent product for older or senior horses who are hard keepers.
This is an excellent product for older or senior horses that are hard to keep weight on. My mare has been on this twice daily since March 2025, and in that time I have noticed a huge difference in her health. She has gained weight, her coat has improved enormously, and her hoof growth and stability are off the chart. Plus, she has plenty of energy for work, but is not in any way “hot” or hard to ride. I like the convenience of this product as well- it’s easy to feed and it’s very palatable, which makes it good for picky eaters. All in all, I give this product 5 stars. Value for money: ExcellentEffectiveness:Also excellentEase of use:excellent

Great product
I will literally swear by this stuff for the rest of my life. I purchased a mare from the kill lot, she came very emaciated and sick. I have her on a 12.5% protein/8% fat grain with alfalfa hay, as well as a pro/prebiotic. She had been on that for a solid 4 weeks before adding this stuff- was gaining weight steadily. I started her on this about 2 weeks ago, sheâs roughly 800-900 pounds, I do 1 scoop twice a day. She loves it, I have no problems getting her to eat it dry over her grain, she licks the bowl clean. She has put on weight much quicker and her coat is exceptional right now. Her mane and tail have also started growing faster. The photos I have attached are 5 weeks apart, sheâs on this weight accelerator the tail end of that. I would recommend to every one, you get a ton of it for not a lot of money; very effective! Overall a great product.

Superior product!
Absolutely wonderful product. Iâve feed several aged and rescue horses with this and they love it, their coats shine and they put weight at a nice even pace. My vet years ago recommended it and with this purchase our new vet gave us the thumbs up! Vet approved, fantastic results.

Seems to be working!
The old guys love this weight accelerator. I top dress their grain with a scoop. They are steadily putting on some weight.

It works
This product is amazing. I own 2 donkeys that were thinner than usual this year, I fed them each 1 small cup/day (provided in package) for 1 month. They both look full and healthy today! BEST THEY HAVE EVER LOOKED!!

Priceless for what you pay for it
After going through a hard winter and my sorely lacking knowledge in equine nutrition, my aging mare lost a noticeable amount of adipose fat and body condition (Went from a 5-4 to a 4-3 on the Henneke chart). After a few weeks of research and learning from my mentor, I stumbled across Manna Pro’s SWA. I noticed that all of the ingredients in SWA (aside from the artificial caramel flavor, which is forgiveable) are quite a dream for older horses. Antioxidants Vitamin C and E to help stop arthritis, Omega-3 to reduce swelling, Protein for muscle building, Fats for restoration of adipose tissue, Biotin for skin and hoof health, and Probiotics to restore the horse’s natural fiber-digesting process. And it doesn’t interfere with the trace mineral supplement that I feed, and has turned out to be a wonderful addition to it. Bravo, Manna Pro! After only 4 months of steady, slow improvement, and proper care in addition to SWA, my mare is back to looking herself and seems happy to be back at work with our riding and adventuring.(Assuming you’ve already spoken with your equine veterinarian) here’s a tip about getting the most out of SWA: Regardless of whether you’re using this supplement or not, horses require exercise and constant access to quality, low sugar (less than 10%) hay. Being without constant access to fiber (hay and forage) is one reason why horses start to lose good body condition. Why? 1) Horses never stop producing stomach acid because (in the wild) they’re always eating grass/forage. Without a constant supply of chewed grass and saliva in the stomach, the acid-dumping creates an acidic gut. 2) Horses naturally have a plethora of bacteria in their hind gut, much of it meant to ferment/break down fiber. This bacteria can’t survive in an acidic gut. And if horses go for hours on end without hay or forage, these ‘good’ bacteria starve and die off (their dead matter causing further problems than just poor digestion). The probiotics in SWA help restore the healthy bacteria (‘gut flora’) to your horse’s digestive system. (We humans eat yogurt to do that). BUT if you want to get the most out of SWA, you can’t go right back to the old routine of your horse not having (low-sugar, high-fiber) hay for hours. Why? Because you’d not be keeping the probiotics alive; they’d die off as you could feed more SWA, and then you’d be creating a bunch of dead bacteria in your horse’s gut. That might exacerbate the problem you started with or create a new one. Rehabilitating the digestive system (and your entire horse) starts with feeding and diet. I think everyone tries to do the best that they can and that’s great! Hope this helps you take it to the next level!

I bought this in May/21 for my 35 yr old horse. He started to loose weight for the first time this year. I prepared my kids ( i have had him 35 yrs) that i might have to put him down before winter and that i would try this. Wow he looks great coming into fall. I will continue with this product and he actually likes it.
