Purple Vitamin Complex contains electrolytes (potassium and sodium) and vitamin B6. Sodium, along with potassium, are electrolytes necessary for proper growth and functioning of the body. Potassium (lost with sweat) influences the process of cell hydration increasing their volume, lowers blood pressure, provides its supply (and deliver nutrients) to the brain, regulates the cardiovascular system, as a calcium antagonist it is suspending permeability of cell membranes. Sodium (like potassium - lost through perspiration) maintains a proper water and electrolyte balance and acid-base balance, regulates blood pressure and transmits nerve impulses to the brain. Vitamin B6 (inositol and vitamin B12 derivative) is a component of many enzymes, determining the course of metabolic processes involved in the synthesis of glycogen and its decomposition form glucose and affects the proper functioning of the nervous system. Purple Vitamin Complex co-creates the formula of supplement Purple Intrain by Controlled Labs, available at www.muscle-zone.pl
