But this transition has not affected the profit of these big Pharma companies which has now turned Big herba companies. The herbal supplement sales is in its peak in United States with people spending more than 23$ billion in vitamins in 2006.

These industries have gained more than 100$ million profit and there are pioneers in this field who contribute to this big total.

Some mentionable names in these include NBTY Inc., in New York that alone made 2$ million profit in supplement sales. There are also other smaller companies that concentrate on particular products. But these niche traders are only a shadow and do not affect the overall total much. Having said about the profits, it is worth mentioning that multilevel marketing is the key to the success of these firms. Added to these marketing techniques, the approval by FDA to exempt these supplements from safety checks is also a plus to these firms.
