A popular delivery form for nutrients is one a day vitamins.  You are no doubt aware that in an ideal world, you would meet your daily nutritional requirements by eating well-balanced meals; however, this is not an ideal world.  You are probably like everyone else, occasionally gobbling down fast food on the run, skipping meals, and buying convenient, nutrient-poor, processed food.  Even if you judiciously choose and prepare the most balanced meals possible, you can do nothing about the nutrient-depleted soil in which our nutrient-depleted food is grown.  To ensure that you have all the minerals and vitamins you need for good health, one a day vitamins are the answer.
 
You may choose to take single supplements of particular vitamins, minerals, herbs, enzymes, or amino acids in order to address specific health problems or to guard against specific diseases.  However, since it is not practical to consume 25 or more capsules, pills, powders, or whatever, every day, it is generally better to take one a day vitamins and add a few other supplements as the need arises.
 
You can find one a day vitamins tailored for the needs of women, men, children, pregnant women, nursing mothers, men over fifty, women over fifty, or any other stage in life.  Read the label to make sure it has nothing added that you are trying to avoid yeast, gluten, eggs, milk, color, salt, preservatives, etc. and select the multivitamin that is best for you.
