Nutrition, Vitamins and Minerals, where can I find a reliable source to know how much is too much?
I am learning about nutrition, for my own interest and benefit. I have a couple of decent books, one with a table of nutritional values of foods.
There are many references to the toxicity of some vitamins and minerals if taken in excess, but nowhere can I find out how much is too much and the symptoms.
Can anyone help, please.

Hi, I know that the toxicity of some vitamins and minerals can be a big concern…after all you’re taking vitamins to be healthy not to be sick.
For example pure vitamin A can lead to a cumulative toxic overdose. This is why it is better to take carotenoids such as beta carotene. Your body will then convert carotenoids into vitamin A as needed. High dose of beta carotene are not toxic at all…your skin might turn orange that’s it!
To avoid toxicity it is important to take good and high quality supplements. The most important thing when choosing your vitamins is the bio-availability which is the % of a dose that can be absorbed and utilized by the cells of your body.
I take high quality supplements since 2006 and I can see the difference.
A good book to help you choose high quality vitamins is the "Comparative guide to Nutritional Supplements".
There are more than 1000 products sold in the US and Canada that have been analysed in this book…a very good reference.
Hope that helps

Hi,
I am always impressed that there is oftentimes some good advice and good links from people helping others through Yahoo_Answers.
After reading your question I saw you might be interested in optimizing your nutrition [(-:] so even though I may not answer your question exactly as you may have wanted it answered, I thought I would take the time to pass on some pointers I have learned the hard way from my own bad ‘uninformed’ choices, so you could learn about good advice and bad advice about good nutritional choices.
After having many bad health problems from listening to people who knew very little about the consequences of choosing LOW nutritional statistics, I really-really encourage you to learn from good nutritionists what to eat for a life time. [See below]
My best to you and to your future health,

I have learned what I now know after my own lengthy research efforts to improve my health – after ‘FINALLY’ listening to unbiased researching nutritionists. I have shared extensively concerning the most critical nutritional statistics that are common to us all at: <> http://answers.yahoo.com/question/index?qid=20091005174358AAgZawf
<>
Also, the only ranking I have ever found to be helpful for me for various foods was from Dr. Fuhrman’s work. I modified his list and posted it at <> http://answers.yahoo.com/question/index?qid=20091016160457AAkysKW

Lastly, after all my previous health problems due to following a-lot of bad advice, I can now understand the frustrations of other health researchers in the following quote within “The China Study” by T Colin Campbell pg 1: >>==>
“Even though information and opinions are plentiful, very few people truly know what they should be doing to improve their health.”
“This isn’t because the research hasn’t been done. It has. But the real science has been buried beneath a clutter of irrelevant or even harmful information – junk science, fad diets and food industry propaganda.”
