It is always a pleasure to hear from someone who was diligent enough to do his research. I got onto it many years ago and have been taking it ever since amongst many other nutrients as well as vitamins, of which I buy most of them in bulk as it is more economical. Along here it may be worthwhile to mention not to forget vitamin C in its buffered form, such as calcium ascorbate and of course vitamin D as one Freeper suggested. We are all creatures of the sun, humans, animals as well as plants.
With sunshine (D) we flourish, without it we just exist. Many years ago I had a similar opinion like many MDs have that in order to stay healthy and well all you have to do is to eat properly until about 40 years ago, give or take I was introduced to a very interesting book called LIFE EXTENTION by Durk Pearson and Sandy Shaw which completely reformed my outlook on what medical doctors call supplementation with chemicals.
Just look at the chemical formula of an egg and if some one would ask you to eat this chemical, you probably throw up your arms and say Heavens no I am not sure if this book is still available or in print, but it certainly had contributed much to my overall health. Matter of fact as soon as I finish here I will check and see if it is still available on Amazon. In any case stay healthy and well.
What do you think about mushrooms(not the kind that get you high)?
