Helps keep my FEI dressage horse calm and settled when we travel and for daily training.
Laurie H.
I am seeing my mare having a calmer attitude. Too soon to know for sure, but she is more relaxed.

I purchased Max Calm for my 7 year old American Saddlebred and it made a world of a difference! Previously he had been unfocused, spooky, and a rearer. Now he is calm, focused, and expresses any discomfort or nervousness in a safer manner.
Loretta Simon L.
Keep encouraging my fellow horsewomen to use this MAX CALM on their spicy mares. Mine has become far quieter and more unafraid of objects.
Lorena L.
Starting with small amount and will use and adjust as needed. It’s being consumed so that’s a big plus!

I have a 5 year old Topper. Low confidence, startled easily on trails. I have had him since he was 2 yrs old. Great horse, strong, friendly. I have tried 2 types of Rx & 2 all natural products but Max Calm is the first that has worked. He no longer is on the edge, it takes a lot to startle him now. The Rx would make him shake his head trying to fight it off.
I can ride with confidence knowing he is not going to jolt, bolt , or be afraid of a stump. I’ve used 2 pumps in a suringe(50cc) orally 1 hour before ride. I received a call at time of order from 100x & then again after I received product.
The customer follow-up & person attention I love. Thanks 100X, I’ll be ordering more

My horse is 7 and pretty nervous. Very watchy and spooky/ jumpy. He's a pig, he loves to eat. I will say, he didn't care for the taste of MaxCalm, but I introduced it slowly and mixed it with vegetable oil. He ate it and we slowly upped his dose to 1 pump. I DEFINITELY noticed a difference. He's still watchy, but the spooking and being jumpy has drastically improved. I am really impressed. If you have a picky eater, you might struggle, but get creative and try different things, it works well.

The Max Calm has really changed my OTTB so much!! I’ve thrown everything at her from different calming supplements, ulcer treatments, patience and/or anxiety training and so far this is the only product that has worked wonders for my girl!! 100x Equine also continued to reach out to me to ensure the product is up to my standards, amazing customer service!!! I’ve recommended this product to SO many of my friends!
Leigh M.
We have a kill pen rescue who clearly has trauma . Poor girl pace is back-and-forth and since using the calm, just one pump a day she has stopped pacing.. with continued love and using the calm product we have been extremely happy with the change in her demeanor within only one month of using the product.
Sue S.
My mare has been the calmest ever! She is finally relaxed at horse shows and seems to be enjoying her self!
Brian L.
Max Calm is amazing, I have tried other products that claimed to calm a high strung horse, Max Calm actually works . I bought an 18 year old quarter horse that had spent many years on the same place with other geldings. His anxiety was through the roof. Wound tight, pacing, wouldn’t eat. It took a few days to get Max Calm to me in Wyoming, but after receiving it, we gave him a double dose to start with and what a difference. He went from trotting the corral perimeter to walking in 4 hours. Gave him a single pump days thereafter and he finally was just standing in his corral restfully. I was so relieved. I think he was too. We continued to give it to him for a week and then discontinued, he’s calm and normal acting. Max Calm was worth every penny, believe me.
Tamara M.
So far I have def seen a diff in my mare. It has been only a week and I can tell she is more relaxed and focused.
Connie W.
Western pleasure horse that was hard to handle in hand. Was nervous in the stall and had difficulty settling in to his new home. But this product definitely helped
Brandy U.
Helped my horse to be more relaxed while under saddle
Germaine D.

Great Products!

We put our daughter’s young breakaway horse on Max Calm just ahead of coming to TJHRA State Rodeo Finals. She has never been a “quiet horse.” Always knickers, is moody, won’t stand still prior to roping. Max Calm has worked wonders! She stood like a perfect young lady waiting her turn, never knickered or pinned her ears. She has walked quietly, not pushing ahead of you like she normally does. When it came time to rope, she stood quietly in the box, but “woke up” exactly as asked, breaking and performing in the field as she always does. This has been a great product! We go to THSRA State Rodeo Finals in Abilene in a couple of weeks, my son’s young calf horse will be on the same product.
Wendy Z.
I started Ruby on MaxCalmer a couple of months ago. Within days I noticed a change. She was more focused on work and less nervous or upset about things around her. I have really been happy with the success of this product!
Holly F.
This was Monty’s first time walking in a parade and running hot laps at a rodeo. We weren’t sure how he’d react so we gave him the Max Calm to take the edge off. I think it helped and he performed perfectly!
Velida T.
My gelding has calmed greatly on this product. Thank you!
Cindy A.
She might just be happy that’s she’s home but I’m not having to handle regumate. she’s relaxed and happy on stall rest and limited turn out. Good deal.
jill b.
Have a QH mare on stall rest since last August
Started her on MaxCalm and saw a calming result for her both in her stall and being hand walked.
Lee H.
I have only been using this for a couple of weeks. It have helped my barrel house be more relaxed in the trailer and overall attitude, but he is still a fire breathing dragon at a race. Hopefully there will be some change on race day after he has been on it a little longer
Lizzie D.
Max Calm !! What a wonderful product ! My girl Delilah is so much more relaxed and present. I’m so glad I started adding this wonderful supplement to her daily feed. Great results !
Diane H.
Since putting my mustang on the MaxCalm, he has been much more relaxed and able to focus when being ridden. He is so much happier and less jumpy with things around him too. A day and night difference!!!!!
Katie
I've had my 14 year old gelding on Max Calm now for about 6 months. I use one pump daily, and then during show days I give 2. He's notoriously a watchy horse, which in turn made me a nervous rider, as i never knew how bad the spook would be. I've tried many other products, but this daily regiment has been a game changer. He is calmer, much more focused, and so much less spooky in all situations. It still can happen now and again, but it's honestly helped ME as much as him. I trust him more, and am less apprehensive whenever we are in a situation that would normally end in some sort of bolt or sideways lunge. Thanks for making a great product that I can rely on!
Michelle S.
Ordered the Calm Max for my 3 yr old gelding. He's not super spooky or strong, but he can just be kind of a jerk sometimes. I noticed the difference right away! He's so much more even tempered and willing! I also really appreciated the call from customer service to check in. You guys have a customer for life!

Loving all your products

I have tried several calming supplements for my competition mare that can be aggressive to other horses, including smart packs. She refused to eat them, whether they were in a powder or pellet. She even stopped eating all of her food at one point. She loves the max calm. I give her one pump every day and two pumps on race days and she’s a different horse. She’s calm in the box and at the gate and so far hasn’t even looked twice at my other horses. I still keep them just for their safety.
Julie B.
I ordered Max Calm on March 17, 2026 so have been feeding it for about two months now. As you can see from the picture, my boy Zoomer is not petite in any way. He is all of 16.2 and 1400 pounds. I'm 77 years old and need him to keep his head about him at all times. He started to seem much more settled after about the first month of feeding Calm. He has his moments and Calm seems to be helping. Another perk of the product is that he licks his grain bowl clean now and absolutely loves the taste of it. I'm assuming it tastes good as I haven't tried it myself. Thank you and keep up the good work 100X!
Sheri B.
It seems to be working so far along with changing his feed.
Leona B.
Ellie has much more concentration in training and has a calmer personality with Mega Calm. Great product for calming trailering anxiety also.
Virginia j.
My mares attitude calmed down a bit using this stuff she was more focused during workouts
Donna J.
My 4 yr old QH mare came to me from AL to WA looking a little light and stressed from travel and drastic changes to her environment. A friend had left over Max Calm so I used it for 2 weeks. HUGE difference. Her stool firmed within 2 days, she began to glow within 7 days and she is starting to really calm her mind. These products are liquid gold.
Teresa R.
The calm x works great for my nervous gelding at trim time.
Nanci Jo D.
I love all the 100XEquine products I get and use! I truly believe they are the best on the market for our horses
Natalie F.
Loving Max Calm. I can see a difference with him being more relaxed in his stall. Has mellowed out enough that everyone in the barn has said something I’m a compliment
Tyler H.
Max calm worked on a mare that hates to be alone , I will use again
CHRISTINE F.
Saphire, red arabian mare. Very opinionated, very hot . As I am an older adult I was advised to sell her and get something quieter...probably not bad idea...but I do not want to. We rescued her I dont want her to be back in bad situation. So in comes 100x calm, I researched ingredients, I decided what will it hurt. So glad I did...she is still an arabian mare and can be up but she is so much more manageable and I can even catch her now. I think overall she feels better in her skin. We have even been out on a trail ride.
Rosanne E.
Max Calm has settled my Arabian overall; he’s less reactive and far more relaxed. Thank 100x Equine for such a fabulous product!
Haley J.
Our trainer recommended these products to us, based off of her great results. We have strong beliefs the calm max will help our mare focus better at training!
Amber D.
Max calm has made a tremendous difference with a couple of our horses that needed it.
Jim B.
Started the calm about three weeks ago. I wish I would have taken some before and after videos but I did not. I only use 1 pump a day. It is like riding a completely different horse. Very happy with the results. After hauling and riding away from home and a little longer on it, I will update again. Thank you for a great product. Getting ready to switch to the joint supplement next.
Carl L.
works well Love it

We've used the Osteo Max for a few years and have noticed a wonderful difference in our mare's overall soundness. But the truly AMAZING product is Max Calm. Gidget has been on stall rest due to a lesion on her suspensory since August 26th, 2025. She was pretty quiet in the beginning but as stall rest does she progressively got hotter and hotter. We took a horse that was in full work, a full training schedule and took away all work and no turnout. We started her on Max Calm in February 2026, within two weeks she went from going airborne and bucking at the slightest sound, to now pleasure jogging along and not having a care in the world. She's more relaxed in her stall and walking it much less and she's a lot less reactive to when children run through the barn causing chaos. Truly can not recommend Max Calm enough to anyone that feels like they are at the end of the rope, this was our Hail Mary before going to heavier medication. This supplement will now stay on as I know this will help her during her start to showing again next year.
Diane S.
This product is great it helps to keep my 5 yo OTTB focused.
Susan L.
This is the best calming product available. It creates focus and willingness to work!
Loretta S.
Better than 2 years of packaged supplements!
Elizabeth M.
I've been using this product for a couple of months. My OTTB seems pretty calm but now considering switching to gut x
Brenda H.
The max calm has been very helpful to settling down the anxiety in my horse. I highly recommend this and all your other products you carry.
Thank you
Jennifer A.
Great product. I saw I difference faster than I expected.
Holly M.
My very spicy mare, Phoenix, is a completely different girl on Max Calm. She’s focused and willing during training a calm when stalled. Extremely happy with her results!
CHRISTINE F.
Dont hesitate.. ..SAPHIRE ...she has been labeled " the trifecta" she is red, mare, Arabian. She is a handful, difficult to catch and usually in high gear. I decided to start again from the ground up and wanted to try a calming supplement to aid in bringing her down a little so she could focus on the tasks. I researched every product and decided on 100X calm. I am so glad I did, she is still an arabian and can get excited but she is more focused, calmer...and I can catch her. She seems over all happier in her body.
Tara M.
Max Calm has greatly helped my new horse settle into his new home. I would highly recommend this product!
Bethanie C.
This product has helped my mare be calm and collected! She tends to be a pretty sensitive and sometimes reactive. This product has helped her be able to “deal” and keeps her using the thinning side of her brain longer! Definitely a win!
Wendy Z.
I have noticed a big difference in my horses focus now that she is on the Calmer. It really works!
Wendy
Krissy S.
Very happy with your products
Jan C.
I have an older Quarter horse gelding that is perfect at home but take him to a horse show and he becomes very nervous and anxious and will not stay focused. I've tried several calming products some with no success others with minimal change. Once I put him on Max Calm our whole show world changed. He is calm and focused. I no longer feel the tension under me which keeps me calm. If something does distract him a small correction from me and he comes right back to me. Our shows are now fun and we are both improving in the show pen. I LOVE THIS PRODUCT !!!!

When Angel arrived here in October 2025, she was a very nervous and untrusting horse. I knew she had come from a bad situation and had been through several hands and I believe had been drugged prior to arriving here. For the first week I couldn't get near her to even get a halter on her. Everything little thing, sound, and movement frightened her. My friend suggested Max-Calm as one of her friends had success with it on her nervous gelding. I was willing to try just about anything to help poor Angel and thought this was a promising start. After using it for a few days (probably 4), there was a noticeable difference in her and her nervousness subsided substantially and I was able to get a halter on her! After another week even more improvements were made and she allowed a fly mask and fly boots to be added to her daily attire! The Max-Calm gave her the stepping stone to develope her trust in me and we have built HUGELY on it since. She absolutely trusts me in whatever I introduce her to and ask her to do, its amazing. I was so disheartened in the beginning and just didnt thing this mare would ever be anything but scared and untrusting. But Max-Calm helped her to get her on her way to be her BEST self! Very grateful for this product! xoxo

My very active 4 year old colt with a big personality has responded with less pawing & nervousness since putting him on the Max Calm.
Donna Y.
Madison has been gre at to work with!

This is tiny . We are using the calming product on him. He loves trail rides but he gets a little nervous sometimes and it really helps him
Wendy J.
I ride and show saddlebred horses and love Max Calm! It helps my hot blooded booger stay calm and focused no matter the situation. I also love that it’s natural ingredients!
Brandy M.
I started the calm x a month ago and have noticed a big difference in his behavior.
Erin R.
I have a mare I started on Max Calm. It is working so well, I'm really happy with the results.
Julie B.
I gave a review when I first started feeding Max Calm to my 16.2 1400-pound "monster". Well, he isn't really a monster and the reason that I wanted to try this product, but he is just a big goober. He seems to be better (not 100%) so I will still continue to use Calm and monitor his demeanor. If the pictures came through, he loves it and licks the bowl clean!
Jill B.
Max Calm has been wonderful for our mare
Holly M.
My spicy red mare is a completely different horse. Focused and calm!!
Deborah M.
This product seems to be working. I give to my Welsh cob who gets very stressed during storms and is a very reactive horse. This has helped to settle him
Elizabeth D.
This product works !
Marilyn E.
My 2 year old filly was very nervous and anxious during her period of getting use to be stalled. I tried the Calm supplement and it help settle her down and relax about seeing the other horses out in the pasture. It was very helpful in calming her so she would stop rearing and being agitated.
Jennifer R.
I used Max Calm on a green horse for the first time this weekend at a show and I am hooked! He acted liked he has been doing this his whole life instead of just starting out. I will continue to add this to my show routine!!
Jenna M.
Love it!
Jennifer J.
Max calm exceeded my expectations. This worked incredibly well. No crazy just calm focus. The customer service is also beyond incredible.
Kaye B.
Showing improvement in calming down.
Callie B.
I’ve started giving this to my two mares and it has made a huge difference! After only two weeks I’m able to walk my Arabian/saddlebred national show horse with a loose rein. She’s calmed down so much and with starting this and being on a diet she has lost some weight! Highly suggest Max Calm!!
Alessa P.
This product is amazing my girl is very nervous it’s to new places and it has done her wonders and has helped her build so much muscles!
Amy A.
I was having a hard time finding a legit magnesium source for my gelding who was an orphan and so lacked nutrition absorption as a foal. Especially without upsetting his digestive system! MaxCalm has helped him feel comfortable in his body again. He even let me lay with him which he has not done since he was a baby! I would be honored to represent 100XEquine as we move up the levels and go out and about. I will be keeping him on this product for life.
Jill B.
Put our mare on MaxCalm for long term stall rest
She is much calmer both in her stall and for her hand walking.
She is also on OsteoMax and improvements have been achieved.
Brenda R.
So far my mare has been calmer. But wish the product came with a pumper top.
Caera M.
My 4 year old Thoroughbred had a severe knee cut which required him to be in a stall with only hand walking for close to 6 weeks. Max calm was recommended to me by my vet! It provided the perfect amount of calmness to be able to hand walk him and then start riding again! Additionally, we moved to a new barn and the transition has been drama free and he's been perfect relaxed. Happy to have this natural option as we make these life changes!
Pam S.
Waylon is a bit reactive, so decided to try max calm. He seems better and more willing to work with me.
Daniel H.
My Horse has been a lot calmer since beginning this product. It has allowed him to focus on what we are doing. He seems a lot happier and his anxiety level in way down. The best part is I can give it as needed.
Geezer B.
It’s working as it should
Rindy
Love their products and fast delivery
Nancy D.
My horse has been in rehab for 6 months; stall rest & hand walking ONLY......this stuff has been a HUGE help ~! Keeps his active mind SANE ~~!!
Jennifer M.
My 4yr old mare Grace is a bit ADD at times and everything (and I mean EVERYTHING) can be a big deal in her precious little head lol. I figured I'd give MaxCalm a try and give it a couple of weeks. Nope, the 1st day I gave it to her I noticed a difference in the 1st couple of hours!!!! With in 2 days she is more focused on me and can complete a workout without getting herself so worked up. It is now a staple in my barn! THANK YOU for creating such amazing products.
bev s.
works real well on our heifer that is still a little wild
Candi B.
My mustang was very anxious and a bully on the ground after being gone for 3 months. I immediately started him on the max calm and after a month he is back to my sweet and loving horse I fell in love with. I trust my non horsey husband to be around him now and is able to feed him without being impatient and invading my husbands space. I highly recommend this product.
Debbie M.
Worked for my mare.
Tracy M.
great product
Alexandra H.
My horse had gained confidence in the show pen since starting this product. We feel that MaxCalm is helping him stay a bit more relaxed and focused.
Sue P.
My horse is so calm, he thinks clearly and calmly! Great product!
Nancy B.
We are extremely pleased with all your products. Max Calm has helped with the transition to bitless riding.
Cheryl W.
It has helped tremendously with my 3yr old Stud to keep him calm and focused when at races!!
Laura V.
I am using Max calm for my 5 year old mare that has been on rest with a suspensory injury and for the most part she has remained calm with her stretch walks around the property. Before max calm when she had time off her stretch walks were much more exciting for her. I am excited to try max calm when we start riding her again.
I also use the gutx and the osteomax and love both those products as well.
Angela G.
It’s helping calm him
Teresa W.
This product (Calm)has been very good for my jumpy mare. We have noticed a great change, as she is much calmer. we trail ride and she will start bugging this spring.
My sister new show mare has also been started on this, just to help her as she is a very young mare. Helping her to train smoothly. Very happy with these products Max Calm.
Thank you
Caitlyn H.
I love the 100x equine products. I’ve seen major improvements in my QH gelding.
