Many have asked about vitamin suplements and there was a very interesting article about where vitamin ingredients actually come from in this mornings newspaper. They mostly come from China, are mostly unregulated, uninspected, untested and produced many times in unsanitary conditions using municipal tap water which is typically unfit for human consumption since it is untreated and full of heavy metals, toxins and disease organisims. When I was in China for 3 weeks last year every one there drinks bottled water, even in Shenzhen, one of the most modern cities in China.
