ProKalm from Science Supplements is a soothing feed supplement for horses and ponies. The feed supplement is approved to compete on. The ProKalm feed supplement is an innovation when it comes to helping horses and ponies perform to their potential with the help of a unique formulation that works as quickly in as 30 minutes with effects of up to 8 hours. At low intake, ProKalm is perfect for "taking the edge off" high-energy horses. With moderate and high intake, ProKalm is suitable for more demanding situations. ProKalm does not "sleep" or adversely affect gait or performance. ProKalm can be given as needed, either for an isolated situation such as competition or given daily in the feed. The effects of ProKalm can be seen within 30 minutes and last for up to 8 hours. The specified amount can be varied to obtain the desired effect. Some horses require greater giving than others. ProKalm contains: Withania somnifera, Passiflora incarnata, Melissa officianalis, L-Theanine, rice flour. A bucket of 3.3 kg is enough for about 3 months.
