From A to zinc, so goes the advertising slogan of a popular vitamin supplement brand. Aside from the assortment of letters and numerical combinations that adorn bottles and packets of vitamins, these represent the amazing complexity of humans’ biological requirements. People who are trying to be healthy should know how important vitamins and minerals are. Most must be consumed by eating the right foods, because the body cannot produce or store them. They're essential to keeping bodies in good health and disease-free. Instead of coughing up quick cash loans for medical emergencies or expenses, people should use the money instead to buy good vitamins and mineral supplements that could dispense going to the hospital needlessly.

In this regard, it is important to examine what vitamins and minerals to take and increase one’s functional knowledge on how to maximize their use to the body. Each of these vitamins and minerals has a specific function in the body systems and it also addresses a natural or artificial nutrient deficiency that could develop due to lifestyle and the environment. First and foremost, it is important to look at the basic categories. There are two vital elements that are important to one’s health and keep the body balanced: vitamins and minerals. The Latin word for life is vita, and the word, amine, means protein. Vitamins also have two groups: the fat-soluble ones like Vitamins A, D, E, and K; and, the water-soluble ones such as Vitamins C, B-riboflavin, and Niacin among others. The fat-soluble vitamins need to interact with body fat in order to be absorbed and maximized by the system. Some foods are naturally rich in fat-soluble vitamins like butter, vegetable oils, egg yolk, and liver. The water-soluble vitamins, on the other hand, are more often found in vegetables and fruits. These vitamins have transient roles in the body because an excess of these are promptly flushed out. These vitamins help metabolic functions, bone maintenance (including teeth and cartilage), even the water balance of the body.

That is why RDAs, or the Recommended Daily Allowance, is important to be understood and followed. Modern medicine, backed by extensive and intensive research, has put together the RDAs for every vitamin required by the human body. This is partnered with a scale known as the International Units (IUs). However, minerals, such as sodium, iron, calcium, and potassium to name a few, are not exemptions to the RDA rule. The human body does not by itself produce minerals so they must be sourced from external supply. So, if people have extra money from bonuses or payday advances, better stock up on good vitamins and minerals for better health.
