Extensive research has been done into the different vitamins and minerals in different foods. We are now far more aware of what different vitamins do, what foods they are found in and how much of each vitamin we should have each day. However just because we know all of these things does not mean that they are easily put into action. We lead busy lives which means that on a day to day basis we tend not to worry about getting the right balance of vitamins, this can often mean that we don't get enough. Most foods contain some goodness in them so we do usually get some, but it is the rarer vitamins that we sometimes miss out on.
There are many different vitamins that fall under the vitamin B category, all of which have different benefits to our body. For example Thiamine (vitamin B1) can prevent weakness and painful limbs, help to keep our heartbeat regular and our nervous system healthy. Riboflavin (vitamin B2) is good for our general immune system and can prevent things such as sore throats, coughs and colds. Lack of pantothenic acid (vitamin B5) can cause acne.
These are just some of the different types of vitamin B that our bodies need to stay healthy and function properly. Even just that handful of examples leaves it easy to see the vitamin is so vital to our body's wellbeing.
That is probably why vitamin B supplements are so popular. These supplements are usually provided in pill form and taking one of these daily is enough. That means that upping the account of vitamin B present in your body does not need to be a struggle and because you are only taking one a day, a pot of them will last you ages which means that you aren't spending a fortune on being healthy either. There are plenty of different health food & supplement stores that stock these different types of vitamin B supplements so it is well worth shopping around and working out which is going to be the type that best suits you and your needs.
