A few public health measures used to lower levels of iron deficiency anemia include iodize salt or drinking water, and include vitamin A and multivitamin supplements into a mother's diet.

Because this drug can interfere with the absorption of certain vitamins (fat-soluble vitamins including A, D, E, K), a daily multivitamin supplement containing these nutrients is recommended.

"In a nutritious meal, vitamin and mineral interaction is minimal," said Dr. Ruth Schwartz, professor emeritus of nutritional sciences at Cornell university, who agreed that normal-strength multivitamin supplements should present no problem.

Because this drug can interfere with the absorption of certain vitamins (such as vitamins A, D, E, K) when used for a long period of time, your doctor may direct you to take a multivitamin supplement.

In otherwise healthy people, some scientific evidence indicates that multivitamin supplements do not prevent cancer, heart disease, or other ailments.

However, a 2009 study published in the same journal found that iron and folic acid supplements were just as good at preventing anemia in children as multivitamin supplements were.

Because this drug can interfere with the absorption of certain nutrients (such as folic acid, fat-soluble vitamins including A, D, E, K), your doctor may direct you to take a multivitamin supplement.

His research led to the development of One-a-Day multivitamin supplements, introduced in 1940.

In 2010, LongeCity pioneered the "crowdsourced" multivitamin supplement "VIMMORTAL" formulated based on suggestions from the community.

So, many of these nutritionists now acknowledge that a daily multivitamin supplement with no more than 100 percent of the recommended dietary allowances will do no harm.
