For daily nutritional requirements to be met, daily vitamin supplements are recommended to be taken by every individual. Vitamins are compounds that cannot be synthesized in sufficient quantities by the human body, and thus are obtained from everyday diet and other external sources. However, nutrients derived from eating certain foods may not be enough to supply the required amount of vitamins for the body. Hence, another source such as daily vitamin supplements packaged as tablets or capsules are made available by nutrition experts.

At present, there are 13 recognized vitamins needed by the human body. Vitamins A and D can be obtained from certain food sources like cod liver oil, while vitamin C is found in citrus fruits and most fresh foods. Vitamin E, on the other hand, can be derived from unrefined vegetable oils as well as from wheat germ oil. From most meat products, vitamins B2, B3, B5, B6, B7 and B12 are obtained, while vitamin B1 is sourced from rice bran. Finally, those leafy green vegetables are good sources of vitamins B9 and K1.

Ideally, proper diet monitored on a daily basis should supply the body with all the necessary vitamins since all of these nutrients are found on food. However, this is not the case for most people. Unbalanced diet leads to insufficient vitamins in the body which can lead to poorer immune system and eventually could result to various diseases. Daily vitamin supplements provide the proper nutrients ingested into the body through direct intake. A number of scientific studies revealed the supplementary benefits of taking vitamins everyday.

For individuals planning to take daily vitamin supplements, nutrition experts must first be consulted for the right nutrients since dietary requirements vary according to age and present health conditions. Once assessed, multivitamins can just be bought over-the-counter.
