Many supplements will not only contain the recommended daily allowance of essential vitamins and minerals, but they will also include other ingredients.
When choosing a product, stay with a vitamin supplement which contains the recommended daily allowance for vitamins rather than mega-doses.
It's always best to try to get your recommended daily allowance of all vitamins through a varied diet of natural, unprocessed foods.
What's more, deficiency could build up over time and for vegetarians, the recommended daily allowance is nearly double that the normal value.
Because the body doesn't absorb non-heme iron as well, vegetarians must consume a greater amount in order to meet their recommended daily allowance.
