Potassium is the third most abundant mineral in the body. It helps the body regulate fluid, send nerve signals and regulate muscle contractions. Roughly 98% of the potassium in your body is found in your cells. Of this, 80% is found in muscle cells, while the other 20% can be found in bones, liver and red blood cells. Inside the body, it functions as an electrolyte. The body uses this electricity to manage a variety of processes, including fluid balance, nerve signals and muscle contractions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4131448/
Potassium is a mineral that your body needs to work properly. It is a type of electrolyte. It helps your nerves to function and muscles to contract. It helps your heartbeat stay regular. It also helps move nutrients into cells and waste products out of cells. A diet rich in potassium helps to offset some of sodium’s harmful effects on blood pressure. https://medlineplus.gov/potassium.html
The body uses this electricity to manage a variety of processes, including fluid balance, nerve signals and muscle contractions. Therefore, a low amount of electrolytes in the body can affect many crucial functions. Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Potassium helps carry electrical signals to cells in your body. It is critical to the proper functioning of nerve and muscles cells, particularly heart muscle cells. https://ods.od.nih.gov/factsheets/Magnesium-HealthProfessional/
Symptoms of hypokalemia include constipation, tiredness, muscle weakness, and not feeling well. More severe hypokalemia can cause increased urination, decreased brain function, high blood sugar levels, muscle paralysis, difficulty breathing, and irregular heartbeat. Severe hypokalemia can be life threatening. https://ods.od.nih.gov/factsheets/Potassium-Consumer/
The body is approximately 60% water. 40% of this water is found inside your cells in a substance called intracellular fluid (ICF).The remainder is found outside your cells in areas such as your blood, spinal fluid and between cells. This fluid is called extracellular fluid (ECF). Potassium is the main electrolyte in the ICF, and it determines the amount of water inside the cells. https://ods.od.nih.gov/factsheets/Magnesium-HealthProfessional/
Many human studies report that nitric oxide (NO) improves sport performance. This is because NO is a potential modulator of blood flow, muscle energy metabolism, and mitochondrial respiration during exercise. L-Citrulline is an amino acid present in the body and is a potent endogenous precursor of L-arginine, which is a substrate for NO synthase. In a clinical study, L-Citrulline supplementation significantly increased plasma L-arginine levels and reduced completion time, compared with placebo. Moreover, L-Citrulline significantly improved subjective feelings of muscle fatigue and concentration immediately after exercise. https://www.ncbi.nlm.nih.gov/pubmed/26900386
Arginine is a type of amino acid, the building blocks of proteins, and is found in animal sources of protein foods. Arginine supplements have been shown to benefit heart health, exercise performance and mental capabilities. Studies have shown that arginine may be beneficial at lowering inflammation and improving cardiovascular health. Furthermore, arginine is precursor to the production of nitric oxide (NO), a type of natural reactive gas that animals and plants create. Since arginine is essential to the creation of NO it has been shown to positively affect the central nervous system (brain, spinal cord, and meninges). This is due to how NO acts in the brain, which is as a neurotransmitter and protective agent against outside threats.
In many analyses, nitrate has been shown to improve exercise performance. Nitric oxide is involved in many cell processes, including the widening of the blood vessels, or vasodilation. Wider blood vessels help increase the delivery of nutrients and oxygen to working muscles during exercise, thus enhancing exercise performance. This has made nitric oxide supplements popular among athletes and persons involved in advanced exercise or physical training activities. These supplements often contain several ingredients that are said to increase nitric oxide, such as nitrate or the amino acids L-arginine and L-citrulline.
