Metabolic Support for Horses

My beloved senior gelding began losing muscle years ago, and then got a PPID diagnosis. Lean muscle helped him overcome the PPID muscle wasting, retain top line, and even helped regulate his digestion. I also appreciate Lean Muscle for its immune boosting effects and am happy to report that after a year on Prascend, my big warmblood’s levels came back within the normal range for the seasonal rise and he does not need a bigger dose of Prascend. Pretty remarkable consistency for a known progressive disease, and I do feel like Lean Muscle is a key part of helping him stay consistent in his ACTH levels, his ability to engage his immune system, his overall musculature and also his good attitude!! He looks as good or better than any other senior at our barn in spite of his diagnosis. Thanks, ImmuBiome, for helping my horse of a lifetime remain strong, happy & healthy in his senior years!!

Lean muscle really works, I’m using it with Spine and Nerve for my 20 yr old who had severe Lymes Disease a few years ago that was caught early but his topline and chest weren't looking as good as I hoped. When I added Lean muscle, he was already on probiotics, it took a couple of months then I started to see a big difference now, I am reordering it -I hope this review helps someone on the fence! He was diagnosed with cushings/PPID in May and was rearing and galloping, before taking the cushings pills so Lean Muscle and Spine and Nerve are super effective.

My horse looks fantastic. He's been off for about a year now with an injury and although still gets turnout and hand walking, he hasn't done much else. I only started the protocol in December 2025 - about 7 months into our year off and he looked better after starting the protocol. I thought he'd lose a lot of his muscle but he really hasn't and I am a big believe it is thanks to the Lean Muscle!

I already had Barry on Nerve and Spine and now have added Lean Muscle…he is doing so much better!

This product is outstanding. We use it for 2 retired jumpers and an older pony. Moving them from FL to NC had its challenges for them physically and Lean Muscle has helped them every step
Of the way. Their coats, feet and most importantly their muscling is so defined. You’d think they were still show horses.

My daughters 16 yr old gelding suffered from EPM when we bought him. We started him on Lean muscle and we havent had any issue with EPM since. Lean muscle has become a staple on our ranch and use it with our mares that are in foal as well for a smoother birth and a healthier foal. I have referred Lean muscle to many friends who has seen fantastic results.

Amazing, quick results! I love immubiome lean muscle! It really works!

My rescue gelding struggled with keeping on weight and muscle. He’s been on about a year of lean muscle and improves every day. The photos are about 4 bottles of lean muscle between them. He’s looking even better now and maybe I can update this later. But I would say he’s improved immensely since I’ve had him on lean muscle and strength and stamina. His joints are nice and gooey and his arthritis seems more comfortable for him even in the winter!

Lean muscle has not only changed my horses, but my client horses as well. I love the pre and pro biotics and natural ingredients. My horses eat it right up, and they look amazing!

My 6 year old dressage mare has been on this a couple weeks. Within days her coat had visibly improved and I like how she is gaining weight/muscle. She has been in full training for 2 years but was still scrawny. The product is not cheap but glad I tried it, she was clearly missing something in her diet which this has helped fill in.

I am so impressed that such a small amount can do so much. My old man is vet checked at mid 20s with terrible teeth. We had been struggling to find something to help him. The video doesn’t do justice. But I’ll put a before video and an after video of him on it for 2 months. I just wish there were more coupons or better discounts.

My mare was on stall rest for 6 months (corollary desmitis) and lost every bit of muscle she had. The trainer who helped me bring her back recommended Lean Muscle Builder. Her massage therapist says Freya has never looked better. She's 26 and I ride her about 3 times a week. We couldn't be happier with the results from this supplement.

My gelding is PSSM1/px. I have noticed his body feels more supple, more forward, less attitude working. I believe his gut feels better.

My gelding was recently diagnosed with PPID (normal insulin & bloodsugar). You could tell that he just wasn’t feeling like himself. I had taken him off of Lean Muscle in an attempt to save money 🤦🏼‍♀️ and I got a vet bill instead. He’s been back on it a month and the improvements are noticeable; better muscle, top line, coat and improved mood. I’m buying the big tub.

This 22 year old that I lease has struggled with weight swings, inconsistent muscle development and maintaining a topline for many years. This product has made an incredible difference in him. Here he is with his Mom!

Our thoroughbred was having trouble gaining weight and couldn’t be ridden to help build muscle. Lean muscle for 3-4 weeks had helped him fill out his top line and start to build muscle as well.

My pregnant mare had terrible FWS. Nothing worked, none of the supplements and tricks made for treating it. My vet suggested calling Immubiome about the "Lean Muscle" for my mare. You said it would be safe and it CLEARED up her really loose stool in a few days. And all is good and well.

My FEI dressage horse has really firmed up his top line and strengthened through his stifles since being on Lean Muscle.
He has always struggled with a bit of stifle weakness which ultimately affected his ability to produce good top line muscle. Well, thanks to Lean Muscle, not anymore!
