Most of us are familiar about the critical role of vitamins and minerals in human body and deleterious health impact due to their deficiency. This compelled the scientists to establish minimum daily intake (Recommended Daily Allowance) of vitamins and minerals. Thus, everyday we need a minimum amount of vitamins and minerals, else we may suffer from nutritional deficiency and serious health complications.
Based on research, it has been found that the micronutrient (vitamins & minerals) deficiency is highly prevalent in the general population and most common reasons are as below:
- Lack of balanced diet
One of the most common reasons of nutritional deficiency is that most of us do not consume a balanced diet. Those who are consuming enough food are also prone to have nutrient shortfall, as it is not always possible for most us to choose food containing recommended amount of all essential micronutrients.
- Increased nutritional need
There are times throughout the life cycle when the body requires more nutrients than the typical diet may provide. Thus, chances of nutritional deficiency may increase.
- Ageing and physiological changes
Ageing is accompanied by many physiological changes that can make it more difficult for nutritional needs to be met. Taste and smell diminish with age and poor dentition limits the food choice to soft foods, dry mouth is common with aging, making swallowing difficult with subsequent avoidance of foods.
- Reduced dietary intake during illness
Reduced dietary intake can be due to illness like psychiatric illness, liver disease, intestinal disease and loss of appetite associated with infection.
- Loss of appetite and digestion due to medications
Medications used in the treatment of chronic illness have a detrimental effect on nutritional status through loss of appetite and digestion.
As we know each and every nutrient has specific role and deficiency of one or more micronutrients may lead to serious health issues. Thus, multivitamin supplement helps in filling the nutritional gap.
Multivitamin supplement has multiple health benefits, here we have highlighted the 7 most important benefits which make it essential to consume on a daily basis:
Weakness, low energy and fatigue could be due to vitamin or mineral deficiency. Vitamins like B1, B2, B3, B5 are essential cofactors in mitochondrial aerobic respiration and cellular energy production. Thus, multivitamins are essential in maintaining energy level.
Under-nutrition decreases immune defenses, making an individual more susceptible to infection. Micronutrient particularly Vitamins A, C, D, E, B2, B6, and B12, Folic Acid, Iron, Selenium and Zinc play a pivotal role in functioning of the immune system.
Bone and muscle health
Vitamins and minerals play both direct roles in brain function (e.g. via neurotransmitter synthesis, receptor binding, membrane ion pump function) as well as indirect roles via their involvement in energy metabolism and modulation of cerebral blood supply.
Minerals are frequently involved in modulating enzyme activity, for example, Zinc is a cofactor for over 100 enzymes, whereas Selenium is required for an antioxidant enzyme glutathione peroxidase. Another antioxidant enzyme superoxide dismutase depends on Zinc, Copper or Manganese.
Multivitamins decreases oxidative stress by scavenging free radicals, thus helpful in maintaining the health of vital organs like the brain, eye, skin etc.
Vitamins and minerals play the preventive role from certain kinds of diseases eg- Vitamin B plays a role in preventing blood vessel disease; Vitamin C and Carotenoids (Vitamin A) play a role in the prevention of chronic eye disease. Vitamin D and Calcium play a role in the prevention of Osteoporosis.
After going through the research article it is clear that multivitamin plays a crucial role in our body and its level in our body should be maintained.
A multivitamin and mineral supplement would be the best choice when it supplies 100% RDA of all essential vitamins and minerals along with ingredients which can take care of oxidative stress (excess free radicals generation). These free radicals negatively impact organ health mainly brain, heart, eye and joint. While choosing the best multivitamin, always look for 100% RDA.
