Which Vitamin Supplement is Best?

Vitamins and supplements are important dietary constituents, as they help the body maintain a proper balance of elements that are fundamental to life. Vitamins are divided into two major categories – vitamin A, also known as retinol, vitamin C, and vitamin D; and vitamin E. All vitamins and supplements fall under this general category, with the vitamins and supplements classified according to how much of each they contain. The classification also determines the concentration of each vitamin or supplement in a tablet or capsule. It should be noted that in most cases, a vitamin and supplements are not classified according to how they are consumed, but rather according to the quantity needed by the body. The best way to ensure that you get all the vitamins and supplements that you need is to take a multi-vitamin containing a complete mixture of vitamins and supplements.

Different types of vitamins and supplements

There are several different types of vitamins and supplements, depending on their specific function. For instance, there are fat soluble vitamins and supplements, such as vitamins A, D, E, and K. These vitamins and supplements are usually separated into soluble and insoluble forms. Soluble vitamins and supplements are often used to improve the nutritional value of dairy products, such as cheese and milk, and to prevent and treat constipation. Insoluble vitamins and supplements, on the other hand, are required to maintain the nutritional value of fruits and vegetables. The vitamins and supplements that fall under this general category include: beta carotene, conjugated linoleic acid, inositol, lysine, pantothenic acid, pyridoxal, thiamin, folic acid, manganese, niacin, phosphorus, potassium, sodium, and zinc.

Randomized controlled trials, which control for factors that may affect the outcome of a study, are the most reliable sources for determining the effects of vitamins and supplements. In an observational study, patients are monitored over a period of time to see what they eat and how much of it, and then given a health supplement. This kind of trial is more difficult to perform than a randomized controlled trial, since not everyone will qualify for it. However, if all criteria for selecting participants are being met, then an observational study may provide valuable data on whether or not a supplement is effective. Thus, although randomized controlled trials and observational studies provide similar information, there are some significant differences between the two that need to be investigated.
