Science Supplements ProKalm - Syringe







The effect of feeding domestic horses a herb extract and amino acid based calmer (PROKALM): a double blind placebo controlled trial. This is the summary of an independent study conducted at Hartpury College*






There are a very limited number of studies examining the effects of calming products on equines and the mechanisms underlying their use. Therefore many of the products on the market are not supported by scientific evidence (Harris, 2007); most companies rely on owner testimonials to evaluate their use, and they do not use controlled trials to demonstrate efficiency (Mckeever, 2005). The aims of the present study were 1) To determine if the reactivity of horses to a novel object test altered after seven days of feeding a commercial calmer (ProKalm, Science Supplements Ltd) 2) To determine if carers and instructors assessed the horse’s behaviour and temperament as having altered after supplementation.



Methods & Materials



Sixteen mature horses without extreme behaviours were selected by the yard manager to participate.  All horses were weighed on a calibrated weigh bridge to determine the quantity of supplement they received.  Horses weighing over 600 kg received 5 scoops of the supplement daily and those weighing less than 600 kg received 4 scoops of the supplement daily (in accordance with the manufacturer’s instructions). 



The horses were randomly assigned into two groups, one half that received supplement X and one half that received supplement Y for seven days.



All horses completed a novel object test and had a temperament questionnaire completed by a student carer and two instructors on day 0.  The horses were then fed their allocated supplement for seven days and on day seven underwent a novel object test and the questionnaire was repeated, to assess any changes in behaviour and temperament (both undesirable and desirable behaviours). 



During the seven days the horses’ management regimens were kept consistent.







Novel object test: Horses in the treatment group ‘settled’ significantly faster on day 7 than day 0 (P<0.05), and significantly faster than the horses in the placebo group (P<0.05).



Horses in the placebo group increased their vocalisation and object investigation on day 7 compared to day 0 (P<0.05), whilst those in the treatment group demonstrated a significant increase in alert behaviours only (P<0.05).







In a group of horses with a range of behaviours typical of horses used for teaching, feeding ProKalm for 7 days resulted in both objective and subjective improvements in behaviour that could be considered desirable for handling, riding, training and competing.

The effect of feeding horses exhibiting stereotypical behaviours a commercial calming supplement







Stereotypical behaviours are common in horses. The purpose of this study was to determine whether a commercially available equine calmer (ProKalm, Science Supplements Ltd) could abolish or reduce the severity of stereotypical behaviours in horses.



Methods & Materials


Fifteen horses exhibiting stereotypical behavior on a chronic and continuous basis were recruited to take part in the study.



Owners were given a questionnaire and asked to describe the type of stereotypical behaviour and rate the severity on a visual-analogue scale with 0 being no stereotypical behavior observed to 10 being most severe stereotypical behavior.



The behaviours reported were wind-sucking (n=5), crib-biting (n=4), weaving (n=4), box-walking (n=2). Three horses exhibited 2 different stereotypical behaviours. Owners were asked to score the horses on Day 1 (prior to treatment) and then on Days 2 and 3.



All horses received 64g of ProKalm split equally between morning and evening feeds.







All horses ate all treatments. The median behavior severity score on Day 1 was 7 (range 3 to 10) and reduced to 4 (range 0 to 8) and 2 (range 0 to 8) on Days 2 and 3, respectively.



Three horses (who all exhibited wind-sucking with a severity score of 7 or 8/10) showed no reduction in behavior severity score as reported by their owners.



The greatest reduction in behavior score was with horses showing weaving and crib-biting. Behaviours reduced on both days of treatment.






Feeding 64g of ProKalm for 2 days split between morning and evening feeds to horses with stereotypical behaviours resulted in a significant reduction in median behavior severity score, as reported by owners. The effect was strongest with horses exhibiting weaving and crib-biting. Further studies using higher doses and for a longer duration are warranted.

Science Supplements ProKalm - Syringe



ProKalm is an innovation in managing anxiety and stress in horses and ponies allowing them to perform to their potential. Once horses become anxious they may develop behaviours that make managing them difficult such as poor concentration, spooking, bolting, pulling, wind-sucking, crib biting, pawing, stamping and box walking.



Stress and anxiety over long periods can also lead to greater susceptibility to infections, gastric ulceration, loss of condition and poor recovery from exercise and competition as well as loss of performance.



ProKalm contains 4 different novel ingredients to help reduce anxiety and nervousness.



ProKalm acts rapidly in as little as 30 minutes and the effects can last up to 8 hours.



At low intake ProKalm is perfect for “taking the edge off”. At moderate intake, ProKalm  is suitable for more demanding situations and at the highest level of intake can be used for horses that are difficult to handle for example during clipping, shoeing, travelling, backing etc.



ProKalm can be fed as required, either for isolated situations or as a daily feed to achieve sustained reductions in anxiety.



However well you manage horses, they are all individuals. Once horses become anxious they may develop behaviours that make managing them difficult and stress and anxiety over long periods can also lead to longer term issues and loss of condition.





Other stress related problems can include failure to train properly, poor recovery from exercise and competition and loss of performance.

ProKalm reduces anxiety leading to better control, better concentration, relaxation and easier management.






ProKalm can be fed as required, either for an isolated situation such as competing or can be fed daily to achieve a sustained reduction in anxiety.





Uses of ProKalm include:


Aggressive behaviour, anxiety, breaking to saddle/harness, starting stalls, bolting, box rest, box-walking, clipping, covering (mares or stallions), dangerous horses, dentistry, difficult horses, introduction to a new herd, introduction to a new yard, massage, problem horses, physiotherapy, rearing, rehabilitation, shoeing, stress, to aid training, to improve concentration in competition, transportation, turning out after box rest, vaccinations, vet visits, weaving, wind sucking.






Science Supplements ProKalm - Syringe 





Feeding Instructions 


ProKalm is best given in feed on a regular basis. The effects of a single feed can begin within 30 minutes and last for up to 8 hours. The amount given can be varied to get the desired effect. Some horses require a higher rate than others.



For a strong calming effect, e.g. to clip, shoe, box or when first turning out, give 2-4 scoops for a 500kg horses in feed or mix with a little water and syringe around 1-2h before peak effect is required.



For a mild-moderate calming effect , e.g. for riding, travelling, etc give 1-2 scoops for a 500kg horse in feed or mix with a little water and syringe around 1-2h before peak effect is required.



For sustained calming over time, for anxious horses or those with vices e.g. cribbing, give 0.5 to 2 scoops for a 500kg horse in both morning and evening feeds for at least 7 days.



For first time use we strongly recommend feeding 2 x 25ml scoops per day split between morning and evening feed for a 500kg horse. If the effect is too strong then reduce the feeding rate




If after 1-2 days the effect is not strong enough increase to 4 x 25ml scoops per day and up to 6 x 25ml scoops per day after a further 1-2 days






Why not magnesium? - There is no scientific evidence that magnesium has any calming effect in horses.



Why not valerian? -  It is illegal under FEI and rules of racing.



Why not tryptophan? -  Tryptophan signals to the body that it is exhausted and has a negative effect on performance.



Why not acepromazine (ACP)? -  ACP during exercise increases risk of in-coordination, stumbling and injury.



ProKalm has been tested to be free from the prohibited substances caffeine, theobromine, hyoscine, hordenine, morphine and atropine.


ProKalm does not contravene FEI rules or rules of racing
