RTD Vitamin Drinks is a category of drinks in a can or a bottle that are ready for immediate consumption. This means that it is not necessary to mix them together with water or any other liquids. The content of select vitamins and minerals is the main advantage of RTD vitamin drinks. For example, magnesium helps reduce fatigue and exhaustion, contributes to the electrolyte balance and affects the function of muscles and the nervous system as well. Zinc also plays an essential role in contributing to the proper metabolism of macronutrients, maintaining healthy bones and normal blood testosterone levels. Women in particular will certainly appreciate its effect on maintaining healthy hair, nails and skin. Last but not least, the vitamins B6 and B12 are also often present in these drinks and contribute to the proper function of the immune system, nervous system, energy metabolism and mental wellbeing.
