️ Why only give the three electrolytes that contain commercial isotonic drinks when we can administer all 108 in sea water?
️ Immune Activation - Aquamarine seawater daily diet is able to activate the immune system, depending on the specific needs of the body. The sodium or chlorine contained in it is essential for the normal functioning of all body cells, including those involved in the immune response.
️ Easier digestion: aquamarine sea water facilitates the digestion of prepared dishes and reduces the usual hyperacidosis in the stomach after eating.
️ CELL NUTRITION: aquamarine seawater provides the food with a greater amount of essential nutrients in a natural, organic and easily absorbed way that can be absorbed by our cells so that they are stronger and resistant to disease.
️ Alkaline Supply: The more alkaline the lifestyle, people become more vital, energetic, healthier, and youthful. Aquamarine seawater is very alkalizing (with a pH of 8.4) and helps us maintain a good acid-base balance.
Optimises recovery: the water lost during exercise should be immediately collected. Water loss is accompanied by the loss of electrolytes, which are essential for maintaining homeostatic balance. Aquamarina sea water integrated into the diet of sports offers you everything your body needs to maintain and restore homeostatic balance.
Liquid removal - diuretics have side effects like all chemical drugs. In contrast, some trace elements in aquamarine sea water, which are regularly contributed to nutrition, stimulate the function of the kidneys by promoting fluid excretion.
Less cooking salt: when using sea water aquamarine in the specified proportions, the addition of common salt is not required. Refined table salt is sodium chloride, but the sodium contained in sea water is organic and easy to absorb by the cells and does not cause high blood pressure.
