Vitamins Benefits
Vitamins Benefits - It's generally accepted that our diet must dontain a minimum of vitamins to stay healthy. How much of which vitamins is needed to not immediately become ill is understood and generally agreed upon by science.
How much of which vitamins we need to actually be fully supplied and to allow our body to function at it's peak at all times it however the topic of myn very controversial discussions. Personally I try to stay on the safe side and prefer to go for the highest recommendations there are. Life Plus supplements allow me to do that and it would seem, that after more than 10 years of daily supplementation, the result give me right:
At well over 50 years, I still feel great, have not had a cold for many years and comparatively to my age peers, I'm more fit and have a greater energy than most.

NutriSearch Comparative Guide to Nutritional Supplements (Professional Version)
I was very pleased with the detailed information regarding nutritional supplements. What an eyeopener! I have been using USANA, which is highly rated, but now I have scientific proof that it is what it claims. I highly recommend this book to anyone taking supplements. It rates hundreds of widely used supplements. - Rosanne Gianotti "gianotti@usana.com" (Kankakee, IL USA)
I really love this book. It is not simply a list with ratings, but a compilation of scientific information regarding supplements and how they effect our health. The NutriSearch team also discribes in detail the evaluation process they used and what the sources are for the standards they measured against. In addition, there are references to the Nutrisearch website which provides even further scientific information.
I also find it entertaining that some people would consider this book biased after evaluating the science? Could NutriSearch be so reckless as to make unsubstantiated claims that could only bring them huge lawsuits from major companies that have low rated products (like Centrum and One-a-Day)?
For some of the previous sour grapes who don't like where their products rate, why not follow the science and select a product that at least has a five star rating. And take the time to actually read this informative book! - Nancy Buschner (Las Vegas, NV)
I use this book for my business. I share it with all of my customers. It not only gives me the ratings of nutritional supplements but does a nice job of explaining "why nutritional supplements". Very informative and educational. I would recommend the book for anyone looking to educate themselves on nutritional supplements. - J. R. Bryant (Exton, PA)

Vitamins - A Definiton
A vitamin is an organic compound required as a nutrient in tiny amounts by an organism.Lieberman, S, Bruning, N (1990). The Real Vitamin & Mineral Book. NY: Avery Group, 3. The term 'vitamin' first became popular in the early 1800s as a contraction of the words 'vital' and 'mineral', though the actual meaning of the word has developed somewhat since that timeSchuman, N, (1998). A History Of COntemplative Medicine. DC: Moseby, 1.. A compound is called a vitamin when it cannot be synthesized in sufficient quantities by an organism, and must be obtained from the diet. Thus, the term is conditional both on the circumstances and the particular organism. For example, ascorbic acid functions as vitamin C for some animals but not others, and vitamins D and K are required in the human diet only in certain circumstances.vitamin - definition of vitamin by the Free Online Dictionary, Thesaurus and Encyclopedia The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, nor does it encompass the large number of other nutrients that promote health but are otherwise required less often.
Vitamins are classified by their biological and chemical activity, not their structure. Thus, each "vitamin" may refer to several vitamer compounds that all show the biological activity associated with a particular vitamin. Such a set of chemicals are grouped under an alphabetized vitamin "generic descriptor" title, such as "vitamin A", which includes the compounds retinal, retinol, and four known carotenoids.
Vitamers are often inter-converted in the body.
Vitamins have diverse biochemical functions, including function as hormones (e.g. vitamin D), antioxidants (e.g. vitamin E), and mediators of cell signaling and regulators of cell and tissue growth and differentiation (e.g. vitamin A). The largest number of vitamins (e.g. B complex vitamins) function as precursors for enzyme cofactor bio-molecules (coenzymes), that help act as catalysts and substrates in metabolism. When acting as part of a catalyst, vitamins are bound to enzymes and are called prosthetic groups. For example, biotin is part of enzymes involved in making fatty acids. Vitamins also act as coenzymes to carry chemical groups between enzymes. For example, folic acid carries various forms of carbon group ? methyl, formyl and methylene - in the cell. Although these roles in assisting enzyme reactions are vitamins' best-known function, the other vitamin functions are equally important.
Until the 1900s, vitamins were obtained solely through food intake, and changes in diet (which, for example, could occur during a particular growing season) can alter the types and amounts of vitamins ingested. Vitamins have been produced as commodity chemicals and made widely available as inexpensive pills for several decades,Kirk-Othmer (1984). Encyclopedia of Chemical Technology Third Edition. NY: John Wiley and Sons, Vol. 24:104. allowing supplementation of the dietary intake.
