Rated 5 out of 5 by from Tamed my crazy yearling filly! Seems to have made a big difference in her demeanor. Much more under control.

Rated 1 out of 5 by from Sad to say not working I am so sorry to say this product is not working and I am using the leaves along with it. My gelding was gone for a month and I thought this would be a good opportunity to give this to my mare while he was gone, to see if it helped with her coming into season IMMEDIATELY upon his return. It did NOT WORK : ( I am so sad, I was very hopeful that the combination of the two supplements would do the trick. My mare is 27 and acts like she is a 4 year old. My poor gelding is constantly running away from her "advances".

Rated 5 out of 5 by from Great results I put my mare on this last month. She was very crabby and moody. This month she is calmer and less moody.

Rated 5 out of 5 by from It works! The product worked great for my moody mare! However, please check and make sure your mare isn't allergic to the ingredients, she started to not want to eat her grain and had a (mild) allergic reaction to the raspberry leaves. This was my fault but just wanted to make you aware to check first! Although it did make her not feel the greatest, I did see a DRASTIC change in her temperament although we only gave it to her for one day, lol. I highly recommend!

Rated 5 out of 5 by from Seems to work I bought this about a month ago and they seemed to have settled down my mare. I am very pleased with the progress she’s made and think these have definitely helped.

Rated 4 out of 5 by from Fairly Effective I think this is a good product. The mare still has her crankiness, but I think it has improved. Like all herbal remedies it does take time. The mare has been on it for 4 months and I intend to keep her on it until winter at least.

Rated 5 out of 5 by from No more moody mare! My mare was an ear pinner before she was put on Harmony pellets. Now she is much more pleasant to be around.
Date published: 2021-09-10
Rated 5 out of 5 by from It Works! This product is one I would not go without for my mare. We all have seen a marked improvement …more patient, calmer, less ‘mareish’ in the pasture with the other girls.

Rated 5 out of 5 by from So far so good! Still a little early for results. I have been giving my fiesty mare for a month. Once I start working her in the round pen I will give another review!

Rated 1 out of 5 by from Allergic reaction This review is no reflection on SmartPak, they're great! The problem was my mare is just sensitive to an ingredient in this supplement and I can no longer feed it. I went thru the process of elimination with all her other supplements and this is definitely the one that has caused her reaction, apparently it is the chasteberry as I waited 2 weeks for her system to clear and then tried her on "simply chasteberry" (which will be my next review) and same reaction only the severe hives appeared much more quickly. I will not be trying any natural herb "calming" supplements on her any time soon!

Rated 2 out of 5 by from Returning mare to SmartCalm Ultra My opinionated and sensitive arabian endurance mare has done well on SmartCalm ultra, but since we've welcomed a new gelding to the farm she's been all about the boy. I thought I'd try SmartMare to get her less focused on him. After a week she became more stubborn, more crabby, and less tolerant than she was previously. So I've stopped partway through my month's supply and am returning her to SmartCalm Ultra.

Rated 5 out of 5 by from Seems to really make a difference I originally purchases this product for one of my mares who has ended up on ReguMate. While waiting for that product to come in, I put all of my mares on Smart Harmony. It seems to have smoothed away the rough edges on all of my mares. The only word I can think of to describe it is "Harmony". They have no trouble eating it and it really doesn't take much per horse. Overall great cocktail of ingredients designed to make mares happy.

Rated 5 out of 5 by from NOT JUST FOR MARES! Everyone thinks their horse is perfect and I am no exception! When my Trainer recommended I try something for my horse's moodiness in the ring with other horses, My first thought was SmartMare Harmony! My horse is not a mare. He is a gelding but I thought he could benefit from the ingredients in SmartMare Harmony and I was right. The raspberry leaf immensely improved his grumpy gelding actions. He would put his ears back when other horses went by him in the ring. He is generally a very happy, very lovable horse but can act "mare-ish" in the ring. The ashwagandha helped reduce the stress he was showing while riding in a group of other horses. It helps keep his focus on what I am working on and not focused on the other horses. The ashwagandha truly evened out his mood and made him less stressed and much happier. The SmartMare Harmony does have chamomile and passion flow as an added ingredient. I wasn't sure how this would affect my horse because I really didn't need him quieter. It basically just took the edge off and made him less anxious around other horses. I have been very happy with the use of SmartMare Harmony on my gelding! I do show at rated horse shows and plan on switching to Smart & Simple Rasberry Leaf, 2 weeks before I show. Please keep in mind SmartMare Harmony has a disclosure: *This product contains one or more ingredients currently published by US Equestrian as a prohibited substance. Please consult the governing body for this and any other organizations under which you may compete. I highly recommend SmartMare Harmony for not only moody mare but also grumpy geldings!

Rated 5 out of 5 by from It really works! My mare was having hormonal issues. She’s always been mareish, but recently she was coming in and out of season frequently, even during the winter. When she was in season, I couldn’t ride her near even a gelding or she would completely lose focus. We were monitoring her and about to do blood work to see if there was something going on, but I decided to try this product first. I’ve had her on the Harmony pellets for nearly three months now, and since then I’ve had absolutely no issues with her and other horses. She no longer stands along the side of the fence, trying to attract the boys. She’s so much more focused when riding and on the ground, it’s wonderful! I’m amazed at what a difference this has made.

Rated 5 out of 5 by from I finally have a quiet mare!! Took about 3 weeks to see a difference, but my mare is much calmer. She still hates being girthed but so much easier to work with. I love the results so far.

Rated 5 out of 5 by from Great stuff! So far this product seems to be helping my mare that produced 'maiden's milk' on a regular basis. She's only been on it a month though - so it's too early to tell for sure.

Rated 4 out of 5 by from Happy mare, happy ride I bought this for my daughter’s 10 year old mare. She was moody, pinning her ears and swishing her tail a lot. She’s been on Mare Harmony for about 6 weeks. She appears to enjoy being ridden more and appears overall happier. She is much more pleasant to ride.

Rated 1 out of 5 by from Bad reaction I am so sorry to report that my mare seemed to have a bad reaction to this supplement. She seemed to become ultra sensitive to light, and ultra spooky. Had her on it about 3 days, took a couple days off of it to return to normal. I have had this mare for 16 years and she has never behaved this way. I suspect the dong quai root powder to be the cause of the reaction. Glad I did some research, and also that she became her normal self after a day or so without supplement. Clearly this works well for many, but not for this mare. I am sharing this information to help others that may experience something similar. I thought maybe my mare’s vision was off, or perhaps her brain was malfunctioning. She is totally fine and back to normal now, and is doing great on her other SmartPak supplements.

Rated 5 out of 5 by from Works Great for my Chestnut Mare I have a 4 year old Chestnut Mare that had the worst attitude outbursts. She would kick out when I would saddle her, or have her around the geldings. I put her on SmartMare Harmony Pellets 6 months ago and have seen a HUGE improvement with her temperament. She is much easier to work with. She lives with two geldings, and knock on wood, she doesn't throw herself into heat or act marish around them. Actually, pecking order wise, she's number three. But I can tell just from using the supplements, it has helped with her moodiness. She doesn't try to kick out, or act moody when I'm tacking her up. I definetly recommend it. I thought in the past I was going to have use the more expensive Vet prescribed hormone medicine to keep her in a pleasant mood. But I'm extremely happy with how these supplements have helped.

Rated 5 out of 5 by from DRAMATIC difference in my young mare If you are looking for an effective mare supplement, this is the one. I wish I would have tried it sooner, but I could not believe it was this effective, and this affordable. It is a game changer. My mare is only 3, and her young heats have been miserable for her. She started rubbing her hips/thigh obsessively against the walls on her first heat as a two year old, so we had originally had her on other brands of "performance" mare supplements, my mare got slightly better on those, but was never quite "normal", still obsessively rubbed that area, and was bald, much to my dismay, and my vets dismay, after ruling out everything else. Eventually after not feeling the "bang for my buck" and with COVID causing life disruptions, I stopped her on the other companies supplement, feeling defeated. After introducing a new horse, a gelding, she got even worse, obsessive, stopped eating, rubbed herself balder on her thigh/hip area, and I finally broke down and tried SmartMare Harmony pellets. Within a few days, she was like a different horse. She has completely stopped that hormonal rubbing, her hair is growing back, and she could care less about other horses. Her heat cycles are mild, and she is a happier horse.
