What is Multivitamin?
“Multivitamin” is a general term for any supplement, usually in the form of a pill or tablet that delivers essential vitamins or minerals. Not all nutrients are present in multivitamins because iron is sometimes omitted. Most essential vitamins and minerals are found in most multivitamins at different doses.
They are usually used to cover “all the basics” when it comes to vitamin and mineral supplements.
Who needs a Multivitamin?
A multivitamin is usually a good idea when:
- They are at risk for various nutrient deficiencies and your diet can not be changed
- Multivitamin provides appropriate doses to cover the risk of a deficiency
- Multivitamin is a better option than the nutrients themselves
Theoretically, multivitamins would offer a greater overall benefit to low-income people, which a wide variety of foods cannot afford. Ironically, this group is the least likely to consume multivitamins.
Multivitamins may also be recommended for pregnant women because of their increased need for folic acid, which is important for the development of the fetus and reduces the complications associated with a complete pregnancy. Older people may also benefit from multivitamins because they are at higher risk of nutritional deficiencies such as vitamin B12.
What Studies show?
A few years ago, a group of consultants from the National Institutes of Health came to the conclusion that evidence of the efficacy and safety of multivitamins is limited and inconsistent.
A study published in the Archives of Internal Medicine in 2009 analyzed data from the Women’s Health Initiative and found that using multivitamins does not reduce the risk of cancer or cardiovascular disease. Meanwhile, two studies published in the American Journal of Clinical Nutrition in 2010 analyzed a decade of data from more than 30,000 Swedish women. It was found that women who took multivitamins were 27% less likely to have a heart attack. In contrast, the second study linked the use of multivitamins with an increased breast cancer risk of 19 percent. Best multivitamin for women over 40
it is very helpful for women. Nevertheless, they were observational studies that could not prove the cause and the effect.
In 2012, two Harvard clinical studies, with 14,600 physicians, showed that patients taking a basic multivitamin were 8% less likely to be in place in 11 years than in the placebo group. However, they did not present a reduced risk of myocardial infarction or stroke. In 2013, an Australian meta-analysis of 21 randomized controlled trials, published in the American Journal of Clinical Nutrition, concluded that multivitamin use did not affect overall mortality.
How to Choose a Multivitamin?
Consumers should eliminate multivitamins bearing more than 100% of consult everyday doses as they may reason vitamin toxicity. The most multivitamin goal is men, women and even the enlarged. Consumers should choose a multivitamin based on age and sex. For those who have difficulty swallowing large pills, capsules and liquid vitamins are also available.
You will also see vitamin-rich foods in some shelves, but at a much higher price. Marketing these vitamins ensures they provide better absorption and digestion, but we do not know enough to validate these claims today. Dr. Stewart explains an advantage:
Dietary multivitamins contain fruit powder, vegetables and other food ingredients, which traditional multivitamins do not have. Multivitamin intake on foods can reduce the risk of stomach upset and can usually be taken without difficulty on an empty stomach.
In any case, you want to consider your specific situation when choosing a vitamin. For example, there are prenatal vitamins for pregnant women to provide them with the extra nutrients they need. Dr. Stewart explains:
The type of multivitamin is important, depending on your personal situation. Women who wish to become pregnant should take a multivitamin with folic acid and iron to avoid birth defects. Women should generally consider a multivitamin with vitamin D and calcium, which can prevent osteoporosis. Most seniors need a multivitamin with a higher content of vitamin D, which improves the strength of bones.
Some multivitamin activities
Some vitamins are soluble in water, others are fat soluble, Zeratsky explains. While water-soluble vitamins pass directly into the body and into the urine (a source of inspiration for the famous “expensive urine” joke in doctors), fat-soluble vitamins are stored and accumulated over time to reach their toxicity. Fat-soluble vitamins include D, E, and A, which are common in fortified foods and multivitamins.
