Formula Highlights

UN-LOCK contains more amino acids, electrolytes and essential vitamins than any formula on the market:

Amino Acid Proprietary Blend

UN-LOCK provides 44,600 milligrams of amino acids per serving, including branched-chain amino acids (BCAAs), L- arginine, L-glutamine and L-carnitine. BCCAs have been shown to lower heart rates during training, provide energy, and buffer lactic acid in the blood. They also assist in muscle recovery from intense exercise and can prevent muscle damage in horses being transported.

Branched Chained Amino Acids (BCAAs):

  • Isoleucine is one of the essential amino acids that cannot be made by the body and is known for its ability to help endurance and assist in the repair and rebuilding of muscle. This amino acid is important to competition horses as it helps boost energy and recover from training.
  • Valine specifically supports lean muscle-mass building and muscle repair. Valine helps prevent the breakdown of muscle by supplying the muscles with extra glucose for energy production during intense physical activity.
  • Leucine is the fourth most concentrated amino acid in muscle; it is not only essential, but beneficial for horses. Leucine helps trigger muscle growth and maintain muscle tissue by sustaining nitrogen balance. Leucine also supplies energy to the body even when under the stress of training, and preserves muscle glycogen used for muscle contraction.

Other Amino Acids:

  • Arginine is a potent nitric oxide enhancer that causes vasodilation of both smooth and skeletal muscles. It also works well to dialate the vessels of the skeletal muscles, improving blood flow to them. Arginine works well in “tying up” type horses. The vasodilating properties are also very useful when treating “bleeders” by reducing resistance to blood flow through the lungs. It is also often used in colic cases to help reduce spasms and ischemia due to insults of the vascular areas of the intestines.
  • Carnitine improves athletic performance, reduces muscle fatigue and improves recovery after hard work. It delays muscle fatigue by reducing lactic acid formation, which allows your horse to maintain top speed longer.
  • Glutamine is the most abundant amino acid in horses' muscles and is involved in more metabolic processes than any other amino acid. Prolonged exercise lowers glutamine levels; using glutamine before or after workouts helps restore glycogen levels, the energy reserve in the liver and muscle that fuels exercise. Glutamine also helps speed muscle recovery and prevents muscle soreness.

Electrolyte Complex

UN-LOCK provides 6,350 milligrams total of FIVE electrolytes per serving. When endurance horses sweat, they lose significant amounts of electrolytes, and — during long rides — calcium and magnesium. When these essential nutrients are lost, acute deficiencies may occur and result in such conditions as thumps and tying-up. UN-LOCK is loaded with electrolytes to prevent this outcome.

The electrolytes sodium and chloride help maintain normal electrolyte balance in body tissues and aid recovery. Potassium, magnesium and calcium are also included to balance and assist in maintaining cellular integrity and healthy nerve, muscle and cardiac function. UN-LOCK is essential support for elite equine athletes.

Essential VItamins

Selenium, Vitamin E and Vitamin C, Selenium, Vitamin E, and Vitamin C are essential muscle nutrients that have each been shown to reduce signs of tying up. UN-LOCK provides effective amounts of each vitamin to prevent horses from tying-up.

  • Selenium: During exercise several chemical processes occur, allowing the horse’s muscles to utilize energy. However, those same processes produce oxidation-induced damage by free radicals. Selenium is a vital part of glutathione peroxidase — an enzyme that prevents free radicals from causing cellular damage. Deficiencies in selenium will directly relate to a decreased ability to rid the muscle of these detrimental substances and can cause tying up. UN-LOCK helps ensure that your horse will not suffer from selenium deficiency or episodes of tying-up.
  • Vitamin C is important in helping to regenerate Vitamin E and other antioxidants to prevent free radical damage that can lead to tying up during intense exercise.
  • Vitamin E works in concert with selenium as a part of glutathione peroxidase. In addition, Vitamin E is thought to play a role in cellular defense of free radicals by incorporating in cell membranes and preventing lipid peroxidation.

Top trainers choose UN-LOCK Advanced Muscle Formula for its dramatic effects on endurance, performance and recovery time in their horses.

It Works!

UN-LOCK is a scientifically formulated, patent-pending nutritional supplement created with one goal in mind: to help horses train and perform at their best. When we were formulating UN-LOCK, we made sure to include only proven nutrients to improve performance, prevent cramping and tying up, maintain top speeds and improve recovery. When this happens, horses obtain dramatic gains in endurance and performance.
