In an ideal world, the food we eat would provide all of our nutrition - not the multivitamin supplements on which moost of us rely. The reality? We eat on the run, often choosing what is available and convenient over what is best for us. People get around this by taking various vitamins and minerals to boost their diet - the hard thing, however, is knowing what nutrients you're missing, and therefore what you should take to fill in the blanks.
The answer to that conundrum is to take an all in one multivitamin supplement. The beauty of an all in one supplement is that it includes a wide range of vitamins and minerals, thus ensuring that you never suffer a chronic deficiency.
A quick look at the ingredients of a typical all in one supplement will show that most of the familiar names are there. You should expect to find Vitamins A, C, D, E, K, B1, B2, B6, B12, Niacin, Folic Acid, Calcium, Iron, Magnesium, Zinc, pus whatever other ingredients the manufacturer chooses to include.
In a combination of this type the dosage should not exceed 100% of the recommended daily allowance of any one ingredient - these products are intended to be taken alongside a good diet, not as a substitute for good food.
In general there is no danger from taking a formula such as this - most of the ingredients are water soluble and are simply expelled by the body if you take more than you need. So whether you are a workaholic parent with little time to eat properly, or a gym nut who is concerned about getting the most from your workouts, a balanced formula of this nature may be just what you need to keep you going at full speed.
