At some point, many of us have experienced a cramp, which is a sudden, involuntary muscle spasm, usually quite painful, that may even make you scream. We could not resist providing help in such situations with MUST CRAMP SPORT, which is a result of a thorough analysis of this problem.

There are many reasons for cramps, e.g. a lack of minerals (electrolytes), dehydration, poor muscle tone, poor physical health, muscle fatigue, muscle injury, uncomfortable work station or even uncomfortable clothes. This problem may occur when you upset the balance between fluid intake and loss, which may be caused by intensive exercise, hot weather, high blood pressure, diarrhea, vomiting, excessive sweating, poor diet, improper cholesterol levels, and some diseases, such as osteoporosis, diabetes, arterial diseases, heart dysfunctions, metabolic syndrome, or by an unnatural body position and even wearing high-heel shoes. Some other conditions, such as venous insufficiency, renal dialysis, pregnancy, nerve injury, motor neuron diseases, neuropathy, deep vein thrombosis (DVT), or amyotrophic lateral sclerosis (ALS) may further be the cause.

The most common involuntary spasms include nocturnal leg cramps, particularly those of calves, but they could affect many other muscles at any time. They can be isolated in nature or recur multiple times, involving a part, an entire or several muscles, sometimes with a visible twitch, lasting from seconds to many minutes. The higher the age the higher the risk of this phenomenon occurring. Apart from skeletal muscles, cramps can affect muscles of various internal organs.

It is true that proper hydration and diet, well-organized exercises, healthy lifestyle, limiting hyper excitability of the nerves that stimulate muscles, and other steps may solve many cramp-related issues. Outside of diseases or unknown (idiopathic) causes we have no control over, any excessive fluid loss, extreme exercise, exhausting physical work, activities you are not accustomed to, and extended unnatural body position can lead to abnormal muscle fatigue with cramps appearing as a result. Although we cannot interfere with your daily routine or tell you what you can or cannot do, our philosophy is to educate you and give you tools, such as MUST CRAMP SPORT, to improve your health.

The combination of high doses of the most absorbable forms of magnesium and potassium complemented with pyridoxine HCL (vitamin B6) proves effective, especially in fighting the charley horse-type-type of muscle contractions – typical for contact sports, such as martial arts, boxing, judo, karate, wrestling, football, soccer, basketball, handball, hockey and ice hockey, just to mention a few. Magnesium citrate, a great neuromuscular transmitter, has a positive effect on a variety of heart dysfunctions and makes for a great help against muscle contractions, weak bones, kidney stones, urinary incontinence, diabetes, premenstrual syndrome (PMS), restless legs syndrome (RLS), erythromelalgia, recovery after surgery and all conditions directly or indirectly related to cramps. Potassium further regulates muscle contractions, maintains nerve functions and regulates fluid balance. Its deficiency could impair insulin production, which may contribute to fatigue, cause blood vessels to contract and hinder blood flow, thus restrict oxygen access to muscles, causing stiffness and aches. Pyridoxine HCL (vitamin B6) is linked to the functions of the nervous and immune systems, contributing to the production of antibodies to fight infections, and hemoglobin to transport oxygen, and its deficiency, which commonly occurs in different diseases, such as liver, kidney, digestive or autoimmune diseases, but also in obese individuals and pregnant women, not to mention excessive smoking and alcohol intake, causes tiredness and lack of energy.

The number of benefits of MUST CRAMP SPORT is so great that regardless of whether or not you are a physically active person, this is one supplement that you MUST have.

WARNING: If you take ACE inhibitors, non-steroidal anti-inflammatory drugs, blood thinners or beta blockers, do not take this supplement prior to consulting a physician or a pharmacist.
