If it is true that when you take vitamins only a small portion is absorbed by your body and is it safe to take 2 or 3 multivitamins in a day?

AnswerIt depends on whether the multi-vitamin/mineral supplement is designed to be taken as a one-a-day, a two, three, four, or even six-a-day. They are designed and formulated differently and are not interchangeable. It is important to follow the directions on any vitamin that you are taking. Without knowing what level of nutrients that is in each tablet, by taking more than recommended dose you could be exceeding the upper level limits on a nutrient, which could be dangerous. AnswerPlease remember that taking more than 1 or maximum 2 multivitamins a day can be very harmful. Taking too much vitamin A every day can cause serious health problems. I have personal experience with this. I over dosed on vitamin A and it almost killed me, ie, violent vomiting, extremely high blood pressure, ambulance, etc.... AnswerYes, it is true. Only about 10% of what is in the pill is actually absorbed with one of the reasons being the binders used to make pills are not readily broken down by the body's digestive system. AnswerRemember that vitamins are not intended to replace a good diet, but merely to supplement the diet in case anything is lacking. There usually are multiple things lacking. It is also important to remember that the vitamin dosages suggested by the FDA are generally believed to be quite low by most alternative doctors. The greatest danger of taking excessive vitamins is iron poisoning. In excess, iron can be deadly; especially the non-organic iron in most retail vitamins, which is a by-product of sulfuric acid and iron. You really should use only food based or food grown vitamins that are found in health food stores. The synthetic vitamins are the ones which the body cannot properly process, and this is the reason why you have vitamin retention rates like 10%. AnswerIt depends on the type of vitamin. Water soluble vitamins are flushed out of your system while fat soluble vitamins A,D,E, and K are not. Minerals are not flushed out either. So taking a few multivitamins a day is bad (because it contains these non-water soluble nutrients). But taking vitamin C (for example) say twice a day due to the fact that it is flushed out with water would not be harmful. ....More of an aspect if you actually need that much of a vitamin. AnswerThere are two types of vitamins. There are natural vitamins, also called whole food supplements, or laboratory made supplements, called synthetic vitamins.

Synthetic vitamins are a chemical copy of a vitamin, but they are not derived from food and thus they do not contain any of the co-factors necessary for the body to recognize it as a food and to use it.

Whole food supplements have much lower dosage because they are absorbed by the body and used.
