Many people around the world use multivitamin tablets every day to improve their health and wellbeing. Multivitamins consist of several different vitamins, combined into a single tablet for convenience; these tablets can be specialised to cater for a variety of needs and demographics.
Why do we need Vitamins
While many of the vitamins and minerals needed by the body are provided through a balanced diet and healthy lifestyle, it is important that the correct quantities are provided to the body. Vitamins are vital in the regulation and processes that occur in the body, across muscles, blood flow and wellbeing.
Who Should not Take Multivitamins?
While many people can benefit from multivitamins, there are certain groups that are advised to avoid using them without the advice of a doctor. People that are being treated for cancer are often told to not take multivitamins, as there is a link to the growing of cancer cells during treatment. This is because the extra nutrients required by the cancerous cells are provided by the multivitamin, where the goal is to deprive the cells of any nutrients.
Lack of Vitamins
Across a large timescale, a lack of vitamins can have detrimental effects on the body, which can sometimes be severe. A lack of iron can cause anaemia, a lack of vitamin B12 can cause nerve damage and poor cognitive responses. Vitamin B12 is often found within meat products, so it is important that this is supplemented within a multivitamin for those that choose not not consume animal products. Multivitamins cannot fully replace the need for vitamins within a healthy diet, but can act as an insurance for the wellbeing of the body.
Studies have shown that daily consumption of multivitamins can help to reduce the harm of likelihood of some chronic diseases, such as colon cancer, heart attacks or osteoporosis.
Key Vitamins in a Multivitamin
Within multivitamins, there are particular vitamins to look out for that could be more beneficial to individual needs:
While vitamin A can be useful to those that have a deficiency, excess vitamin A can be detrimental to health and is shown to have negative effects on the bones or liver.
It is important to have a good level of vitamin C to promote healthy cells and skin.
Vitamin D is an important vitamin for calcium regulation in the body, while also having links to cancer prevention. It can be necessary to need more vitamin D than the multivitamin contains.
Vitamin E acts as an antioxidant within the body, helping to prevent damage to cells caused by free radicals.
Iron is used within the body for the production of red blood cells, which are used to transport oxygen. While this can be useful in a multivitamin for women, it is not usually necessary for other groups.
Pre-menopausal women can benefit from the addition of folic acid in a multivitamin, as it can prevent potential defects and issues within the early stages of pregnancy.
