Stress-Less is a completely different sort of canine calming supplement. Unlike other products, Stress-Less does not include any drowsy ingredients such as valerian, herbs or L-tryptophan. Our key ingredient is MAH® magnesium, which works by helping your dog to cope with the stresses of everyday life, work and competition.


The German Pharmaceutical company, Verla-Pharm, pioneered a unique method of refining magnesium to create Magnesium aspartate-hydrochloride - MAH®. A completely different and superior grade of magnesium that is exclusive to Nupafeed.


All animals need to have the correct balance of calcium and magnesium. When a dog is highly strung or becomes stressed, anxious, nervous or excited, they burn off magnesium. This allows calcium to overload muscle and nerve cells and replicates the rise of adrenaline. This can cause erratic behaviour, sensitivity, nervousness, aggression and/or tension.

Nupafeed Stress-less uses a water soluble, complex, pure, amino magnesium which is able to enter the dogs’ system efficiently and absorb into body tissue. Stress-Less maintains the healthy balance of calcium and magnesium to keep the dog settled, but without compromising performance or having any drowsy effect.


Nupafeed Stress-less calmer can be introduced to the dogs’ diet by adding directly to the normal feeding regime or administer directly into the mouth. The compound is totally safe and allows the level to be adjusted, enabling owners to find a level that suits each individual animal. Ideal for all working dogs and those taking part in competition.
