Product details
• Helps support a calm and relaxed demeanor in mares
• Supports mood and normal muscle function
• May be beneficial for nervous or excitable geldings and stallions
HAPP-E-MARE is a veterinarian-developed equine supplement designed to support balanced behavior and physical comfort in mares during seasonal transitions and throughout the estrus cycle.
Mares are long-day, seasonally polyestrous breeders - meaning their reproductive cycles are influenced by daylight changes. As days lengthen in spring, mares typically enter estrus, and as daylight decreases in fall and winter, they transition back into anestrus. These phases, particularly the transitional periods, can last 60-80 days and are often associated with shifting behavior and sensitivity.
HAPP-E-MARE provides targeted nutritional support during these times, helping to maintain a calm demeanor and support normal physical comfort. This supplement may also be beneficial during regular estrus cycles by promoting a balanced temperament and supporting normal muscle function.
The formula features a unique blend of herbs, minerals, and a high level of natural Vitamin E in a palatable powder form. It is suitable for use in mares, as well as geldings and stallions during periods of training, travel, or other forms of stress to help promote relaxed behavior.
Important Notice: Not for use in breeding, pregnant, or lactating mares. Always consult with your veterinarian before introducing any new supplement to your horse's regimen.
Developed by Dr. Frank Reilly, DVM, an equine veterinarian with expertise in metabolic health, nutritional balance, and seasonal wellness support.

One of the mares I leased for lessons would hit her body on the wall when in heat. Cleared from the vet of all possible issues and Happ e mare fixed her in about a month. I took her off of it to see if there was a difference, and WOW. HIGHLY suggest to all my mare people!!!!
This product has helped my nervous gelding get back to focusing. He is anxious and works himself up around new venues and especially at shows. He wouldn't drink or eat at a horse show no matter how long we’d been there or how hot it was. He was always tense and tight lipped, unable to pay attention, staring off as though trying to find someone he knew. It was dangerous for him even though he always performed well. I started him on this and he is chill as can be. He can munch away on his hay now and watch the goings on without fretting and working himself into a tizzy. He is so much more relaxed. Thanks Dr. Reilly for really caring about horses and making such great products!
Being in the horse business over 45 years ,
This product simply gave me the best results I have ever had with difficult moody mares .
Thank You Dr Frank for being a horseman helping other horsemen to make our horses happy to enjoy their journey!🙏🙏🙏🙏🙏
Our Hanovarian mare would be very "mare" when she is in season. We started using Happy Mare about 3 years ago and it really calms her swings in hormones. Great product. It seems to work well.
Happ-E Mare has been a miracle worker for my mare! This supplement has helped ease her symptoms while she is in season, allowing us to continue to work through each cycle. The addition of crucial vitamins and minerals are an added bonus.
Rose is my main lesson horse. She and I have had a long road together, not the least of which included ulcers, a false pregnancy and constant hard cycling for an entire year. The ulcers were treated first, then her cycles. I started her on Happ-e-mare and saw some improvement. We did a single injection of Depo to break the hormone cycle and kept her on her supplement. She has had normally timed cycles since and is no longer crabby, uncomfortable or distractable. Even while cycling she will ignore the boys to come in for feed. She’s a completely different horse and able to focus on being a beginner lesson horse, where she is an absolute gem.
We brought home a a older mare that became a out of control horse around our boys . we tryed other supplements and nothing worked . we thought about rehoming her . it took about 20 days of 2 a day of Happy Mare to take hold but now she is a happy mare and enjoying life . will not be with out it .
I've got a very anxious mare that I've had for almost 20 years. I'm on my second tub of Happ-E-Mare and I've found that it really helps keep her more level headed. I actually look forward to working with her now. FYI- my horse is also super picky and gonna this stuff right up.

Normal Estrous Cycle
1. Mares are “long day, seasonally polyestrous breeders.”
As the days get longer (more light in a 24 hour period), they start cycling. As the days get shorter (in the autumn), they stop cycling. Their cycle lasts spring, summer and early fall. In late fall and winter, the mare is in anestrous – there is no cycling. In the spring, they go through a transition phase, where they go from anestrus back to estrus cycling, This also occurs in the fall when they go out of estrus cycling.
These two transition phases will have an abnormal cycling times and that leads to a stressful time for mares – it can last for 60-80 days, but can be in and out of heat within only a few days for example.
The usual estrus and diestrus days are not on schedule. They are irregular in timing, making behavioral patterns erratic.
• Click here for Dr. Wolfsdorf’s article on Transition Periods in The Horse Magazine, 2016
2. In anestrus (late Fall & Winter), even though mares are not cycling, they often will have behavioral problems. They may be mildly receptive to a stallion still or even be fully receptive all winter.
3. Polyestrous means they will have many cycles during the long day times of the year – each estrus cycle is 21 days long.
• For 4-6 days, a follicle forms on an ovary during estrus and mares are receptive to a stallion.
• For 16-17 days, the mare is in diestrus where the corpus luteum forms on the ovary and the mare is not receptive to a stallion.
• Click here for Dr. Sertich’s article on the Reproductive Cycle of the Horse in the Merck Veterinary Manual.
4. Control of estrus depends on control of hormones. In estrus, the main hormone is estrogen. In diestrus, the main hormone is progesterone.
• Click here for in depth info on mare cycles from Ontario Department of Agriculture.•
Mares are different from humans.
1. Mares will continue to have cycles in estrous throughout their lives – there is NO menopause for mares!
2. Mares do not menstruate. Often you will see products with “PMS Formula” – technically this is not true since mares can not get PMS. Some mares do have many of the signs of PMS, but it’s important for owners to know this difference.
Insulin resistance will cause inability of the mare to get pregnant, can cause foal loss (abortion) or laminitis in the late stages of pregnancy.
If your mare is prone to IR via genetics or eating patterns/diet, it can affect their behavior and estrus cycle pattern.
Click here to visit the Insulin Resistance section of our website to see how to help avoid IR.
* Heiro is used to get pregnant, stay pregnant, and avoid laminitis in insulin resistant mares.
Often owners will comment that their mare started a laminitis bout when she started coming into heat. Why is this happening?
1.These mares are already IR (insulin resistant) and are on the edge of high blood insulin creating laminitis – the start of their heat cycle is the final push over the cliffs edge.
2.There are several studies showing high amounts of estrogen can trigger insulin resistance – in mare going into heat, estrogen levels are increasing and peaking. The exact mechanism of estrogen’s effect on insulin resistance are still being studied (some studies conflict on findings), but here are 3 studies showing estrogen’s ability to add to insulin resistance.
A. Insulin Sensitivity is Decreased in Normal Women on Estradiol Doses.
1. Estradiol supplemented decreases insulin sensitivity.
2. This effect was not in all subjects.
3. Note from Dr. Reilly: “This must suggest that this effect will not occur in all mares”.
Click Here to view Dr. Kojima’s article on mayDecreased Insulin Sensitivity
B. Effect of Estrogen on Insulin Sensitivity.
1. Moderate estrogen doses may actually increase insulin sensitivity, but higher doses of it creates Insulin Resistance.
2. Note from Dr. Reilly: “Estrogen peaks early in heat cycle might be when we see problems in sore mares that are IR/prone to estrogen peak hyperinsulin”.
Click Here to view Dr. Lindheim’s article on the Effect of Estrogen on Insulin Sensitivity
C. Estrogen Given to Men Induced Insulin Resistance.
1. 18 men given high dose estradiol.
2. Estradiol treatment in men can induce insulin resistance in healthy subjects.
3. Note from Dr. Reilly: “Using this hormone in a male and creating IR is strong evidence of estrogen having a role in insulin action”.
Click Here to View Dr. Polderman’s article on the Induction of Insulin Resistance.
* Mares that are already IR are more prone to hormone shifts/stress
D. Stress of Coming into Heat
1. Stress raises cortisol and that hormone interferes with normal insulin action, which creates a insulin surge to overcome this interference. If already IR, becomes very IR and laminitis triggered
Low Thyroid Hormone – many mares will benefit from a combination of Happ-E-Mare and ThyroL powder. Have your vet test the mare’s total T4 level. Often, they are SUBOPTIMAL and run at the bottom of the normal range – we need them at the top of the normal range.
1-2 scoops (12-24 mg) of ThyroL can help bring your mare to the top of the normal range for optimal immunity and muscle health.
Example:
Test #1 T4 = 1.3 (where the normal range is 1-3)
Test #2 T4 on ThyroL = 2.7 (top of normal range)
On tests, DO NOT ACCEPT “it’s normal” – we know that.
Think of it this way:
You get into a car accident and are taken to the hospital.
Dr. A is 1 year out of school and has license.
Dr. B is head of surgery, 30 years of experience, wrote 2 books on trauma and has license.
BOTH are normal, but you know who you would choose.
External Reproductive Tract Anatomy Problem
If your mare’s vulva tilts inward, manure has a tendency to pour out onto her reproductive tract, which leads to urinary tract infections. The mare might urinate more often, feel poorly and not really care if a stallion is around – this can lead to problems in gauging where she is in the estrus cycle. She may be resistant to being ridden and not be able to focus due to having an infection. These infections can also progress to uterine infections. Excess fluid and inflammatory cells build up in the uterus. Uterine infections lead to short cycling – the time out of heat is very short, so she is in heat more often.
Click here for Dr. Cook’s article on Mares and Hormones from The Horse Magazine, 2012.
1. Transition periods of abnormal estrus cycles – 60 days in spring and 60 days in fall
2. Hormonal swings of coming into heat – from progesterone to estrogen control There are approximately 11 estrus cycles a year, creating behavioral and physical changes in your mare.
3. Anestrus (“in heat”) abnormal issues – mare is NOT to be cycling then, but many mares exhibit “in heat” signs in the winter.
Often, horses do not have a hormonal problem but still need a calming aid for their nervousness. Happ-E-Mare can help them by reducing inflammation, helping immunity, easing their stomachs and supporting muscles so they feel better. Sometimes nervousness is caused by discomfort. Happ-E-Mare is good to use in both mares and geldings!

Regumate is a synthetic, progesterone-like oral hormone.
1.Problem #1: Regumate is prescription only. You can not get it at the store or online without a veterinary prescription. Happ-E-Mare is available in stores and online with no prescription.
2. Problem #2: Regumate is $2.50 per dose. Happ-E-Mare is only $0.95 a dose – if feeding over an 8 month period (spring to early fall), that’s $372 in savings!
3. Problem #3: Some mares have adverse reactions to Regumate. They can become more spooky, nervous or aggressive. Happ-E-Mare’s all natural formula works to calm mares.
4.Problem #4: Missing a dose of Regumate will result in your mare coming into heat. If you run out and skip a dose one or two times, your mare will come into heat. Restarting it will have no effect for at least a week. Happ-E-Mare will NOT cause hormonal crashes if a dose is missed.
5. Problem #5: Regumate is not approved in geldings. Happ-E-Mare is approved for use in geldings who need calming for better focus and better performance.
6. Problem #6: Regumate is synthetic and contains no added herbs, minerals or vitamins. Happ-E-Mare is made from natural herbs, minerals and vitamins.
7.Problem #7: Human contact with skin can result in hormonal imbalances in people. Regumate can be absorbed through the skin.
* You can give both Regumate and Happ-E-Mare together and then slowly wean off Regumate.

Does your Jenny (Female Donkey) get Moody?
1.Yes, she can use Happ-E-Mare! They have the same reproductive cycles as mares.
2 Happ-E-Mare can help them to be less anxious and nervous, and more comfortable.
3. Donkeys are more prone to Insulin resistance if miniature – you can use Happ-E-Mare and the Heiro program together!
4.Many Jennies have reproductive problems if IR. If you plan on breeding your donkey, discontinue use of Happ-E-Mare, but continue the Heiro program through pregnancy and nursing.
Happ-E-Mare has 9 natural herbs with no loss of potency from being processed with heat (200°F steamed heat) to produce a pellet. “Pellets are hot when they leave the pellet die because of heat coming from steam conditioning.”
Click here for an article on Equinews regarding pellet processing.
If Happ-E-Mare went through the extrusion process, it would cook the herbs at 260°F.
