## Overview

HAPP-E-MARE is a veterinarian-developed herbal powder supplement designed specifically for mares to support calm behavior, balanced mood, and normal muscle function during seasonal transitions and estrus cycles. Featuring a potent blend of natural herbs, magnesium, and high levels of vitamin E, it promotes physical comfort and emotional stability. Easy to administer as a palatable powder mixed with daily feed, it’s trusted by equine professionals to help mares maintain composure and suppleness through hormonal and environmental changes.

## Description

HAPP-E-MARE is a veterinarian-developed equine nutritional supplement formulated to support calm behavior and physical comfort in mares during seasonal transitions and throughout the estrus cycle. It is designed to provide targeted nutritional support during periods when hormonal changes may influence demeanor and sensitivity. Mares are long-day, seasonally polyestrous breeders, meaning their reproductive cycles are influenced by changes in daylight. During transitional periods in spring and fall, behavioral and comfort changes may occur. HAPP-E-MARE delivers a carefully selected blend of herbs, minerals, and natural vitamin E to help maintain a relaxed demeanor and support normal muscle function during these times. This palatable powder is suitable for mares and may also be used for geldings or stallions during periods of training, travel, or environmental stress. Developed by Dr. Frank Reilly, DVM, HAPP-E-MARE is made without artificial colors and is intended to be used as part of a balanced feeding program. Always consult a qualified veterinarian before introducing new supplements to your horse’s routine.

Review: This stuff SAVED my aggressive mare from being sold! - Okay, Happ-E-Mare literally saved our mare, and all our sanity! Our 6yo hunter/jumper mare is amazing when it comes to people, she cant get enough of being touched. But she was a nightmare with other horses! She is aggressive to the other mares all day in turn out, she with spin sideways to kick any horse walking by on the cross ties, she will literally spin or go in reverse to kick any horse that gets within 10 feet in the arena or trail riding. And I swear she was in heat YEAR ROUND squirting, winking, squealing and acting like a hussy. So it wasn't just behavioral, it was hormonal driven for sure. We love her, but it was becoming a nightmare to ride with anyone near by. We have tried raspberry leaves, did nothing other than she loves them. Magnesium Oxide actually did help take the edge off and pull her out of Estrus finally in January/February. The physical signs of estrus resolved with the magnesium, but the aggression towards other horses and ear pinning, crazy eyes didn't. We were contemplating inserting a marble into her uterus this spring before trying regumate. Enter...Happ-E-Mare. Granted it's only been 2 weeks, but I noticed a significant shift in her behavior within 2 days! I honestly am completely over the moon about this right now! She is no going after the other mares in turn out, still pins her ears but there is no actual going on the attack. She now allows people to walk their horses by on the cross ties, ears pinned but not spinning sideways to smear them against the wall. She actually seems to have forgot to notice other riders in the arena! Not even pinning her ears while riding, but more focused on her work and listening to her rider! Her body seems more calm and supple physically around the bends with better lateral flexion, she's dropping her head and rounding out her back (we also have a new bit, so that could be it too), not thrashing her head around getting all pissy, and she hasn't bucked or crow hopped once since we began the Happ-E-Mare 2 weeks ago! All this, and it's only been 2 weeks...and it's SPRING!!! I can't even say it could be a fluke, because all the other mares are going into spring heat, and so was she just before we started this supplement. But now I don't even see winking, squirting , or rubbing her butt against the wall to the gelding next door as she was just before we started this. And can I tell you...I feel way better about my daughter riding, and even more so for me...because she has thrown me horribly twice during spring heats...and my daughter into jumps. So this stuff may have just saved her from being sold. I will update as we go along deeper into spring 2019, but I just wanted to review this as I see there aren't any reviews anywhere on this stuff. I'm guessing maybe its a new product, but if my review can help anyone out there...please try it! What do you have to lose? If it doesn't work, just return it!!! Gotta love desertcart! UPDATE: (10/16/19) I am still in disbelief at what a different horse she is! She is literally the best tempered horse ever now! She gets her Happ-E-Mare daily mixed with diced apples and if we miss more than three consecutive days she starts going into heat and starts to show signs of agitation and aggression towards other horses, so we keep her on 1 scoop daily as consistent as possible. She is a little sweetheart and will jump the moon for us, all snuggles and cuddles. I wish more people knew about this supplement, because I truly was at my wits end. I literally think it would save a lot of "unfixable" mares from going to the slaughter. I really do.
Review: Consistently beneficial - It helps my mates to cycle more even keel instead of intense mood swings during their heat. I have a proud cut gelding who benefits from its calming nature too. Expensive but will continue to use it because it works. Simple to use, just add a scoop once a day to their feed or grain

## Questions & Answers

**Q: Is this pellet form?**
A: It is a powder, not a pellet.  My mare had no problem with it as top dressing.  But she also eats everything, has never turned her nose to anything edible

**Q: Anyone use this on gelding that like to play stallion?**
A: Yes we have an 8 year old appendix gelding that thinks he is all that.  We kept him in for about 3 months and it helped some but he is so much of a goober and always so anxious with or with out the mare around, that our vet had to prescribe him something stronger

### ⭐⭐⭐⭐⭐ It really works!
*by R***D on May 17, 2023*

Last summer my 9-year-old mare started exhibiting pain with her cycles. Since this was new, I had my vet out to ascertain she didn't have a cyst or something similar. My vet recommended Regumate. I didn't want to go that route but needed something that alleviated her pain. I saw Dr Reilly at Equine Affaire where he had all his products on display. Knowing that Heiro is fabulous and really works, I was very interested in the Happ E Mare. I immediately started her on it. Wow! Within 3 days, my sweet mare was her old self. She no longer shows pain in her cycles and is able to focus. This product really works!
