Trouble Free contains a blend of ingredients that support normal nerve cell and muscle function in the horse.


Alpha-lactalbumin is a major whey protein found in mammalian milk and contains high quantities of several types of amino acids, including cysteine.

Researchers believe this compound helps boost the immune system. It also contains naturally occurring compounds that the body converts to serotonin that supports a positive mood and lowers stress levels.


Thiamine, or vitamin B1, plays an important part in the transmission of nerve impulses throughout the nervous system. It also plays a role in the normal metabolism of carbohydrates, fats, and proteins. Unlike many of the other B-vitamins, microorganisms in the intestine do not make enough thiamine to meet the horse’s needs; however, both fresh forage (green grass) and grains are good sources of thiamine. Exercising or stressed horses may have higher thiamine requirements than can be met by diet alone, so supplementation is suggested. Horses with little or no access to fresh grass may also require supplementation. Thiamine deficiencies can result in a number of different nervous disorders and hyperirritability. Some symptoms of thiamine deficiency are weakness, poor appetite, weight loss, incoordination, and nervousness.


Taurine is an amino acid that is critical for proper nerve transmission and muscle function. Taurine assists in nerve impulse generation by standardizing the flow of electrolytes (potassium, sodium, calcium, and magnesium) in and out of the cell and it acts to stabilize cell membranes by modifying neurotransmitters like glycine and GABA. Taurine is also thought to have some antioxidant and detoxifying properties.


Inositol is related to B vitamins and is a common component of cells. It supports electrical impulses and nutrient transfer across the cell membrane. Inositol is involved in the actions of serotonin, which reduces anxiety and supports calmness in horses.


Magnesium is often referred to as the “anti-stress” mineral. It aids in the maintenance of a calm demeanor by relaxing nerves, relieving tension, and modulating the electrical potential across cell membranes. It also activates enzymes important for proper protein and carbohydrate metabolism. Magnesium plays a role in many systems of the body. It aids in regularity, supports restful sleep, and helps to purify body tissue. Without adequate levels of magnesium the normal production and transfer of energy, muscle relaxation/contraction, and the conduction of nerve impulses would not occur.

Under normal circumstances, diet can meet the magnesium requirements of most adult horses; however, pregnant and lactating mares, young growing horses, stressed horses, and especially horses in moderate to heavy work have additional requirements for magnesium. While deficiencies can be seen anytime, some horses have major issues in the spring, when fast-growing grasses are high in sugar and low in magnesium. It is not uncommon for some horses to become more excitable at this time of year. Signs of magnesium deficiency include nervousness, excitability, and muscle tremors.
