Multivitamins are nutritional supplements made up of vitamins, minerals and other nutritional elements. The food we eat also contain these vitamins and minerals. The reason why people take multivitamins is they may suffer from a vitamin deficiency or may not get enough vitamins and minerals from everyday food.
Due to soil depletion and processing, the foods that should contain all the vitamins for the needs of your body have been stripped away. Despite this happening, there is still no an excuse to not eat wholesome food close to its natural source.
Depends on the point of view of various parties. Companies that make multivitamins will tell the public they should take a multivitamin. This is how they make money.
If you are eating wholesome nutritious food, there is no need to take a multivitamin. My suggestion would be that you see your doctor/health professional to help determine whether or not you need to take a multivitamin.
If it is found out you are suffering from a vitamin deficiency, cannot eat and digest big quantities of food, have an occupation that requires your body to have more multivitamins than the average person, then you may have a reason to take a multivitamin.
If you take a multivitamin when it is not required, all you are going to be doing is taking an expensive trip to the toilet. Taking a multivitamin is still no excuse for eating a nutritionally poor diet.
At the end of the day, whether or not you should take a multivitamin comes down to the personal choice of the individual concerned.
When purchasing a good quality multivitamin, it is important to know what elements they contain, look for a scientifically unbiased review to determine if the brand you are looking at is of good quality, determine your needs based on age, gender and level/type of physical activity. Another important aspect to look for is the physical form the multivitamins come in. These can include, tablets, liquid, capsules and powders. Each form can influence the life span of the product, rate of absorption and how well the body utilises the minerals and vitamins.
These are some of the various forms that nutritional supplements such as multivitamins come in. These forms influence the speed in which the product is broken down, absorbed and utilised by the body. Production costs can also influence what form is used to manufacture multivitamins.
This is where two piece gelatin capsules containing the product are quickly broken down in the stomach. These are more expensive than tablets, are easier to swallow than tablets and also have a shorter shelf life than tablets.
They are cheap to produce and convenient to consume. You can also change the size of the serving compared to capsules and tablets.
Like powders, tablets are cheap to produce and contain the most amount of product in a given space. They have a longer shelf life than liquids, capsules and powders. On the downside, tablets can be difficult to swallow compared to powders, capsules and liquids.
Like powders, liquids are easy to swallow, are convenient, and the size of the serving can be changed. The downside of liquids is they have a shorter shelf life than tablets, capsules and powders and are heavier to carry.
