The Life Extension Foundation is a company that sells supplements and vitamins. Its claimed goals are to extend the healthy human lifespan by discovering methods to control aging and eradicate disease. It is headquartered in Fort Lauderdale, Florida. It also has a call center location in Las Vegas, Nevada.  Life extension is the idea of extending the human lifespan, either modestly – through improvements in medicine – or dramatically by increasing the maximum lifespan beyond its generally settled limit of 125 years. The ability to achieve such dramatic changes, however, does not currently exist. Bottom Line. If you want the highest quality, most effective, and most potent vitamins, minerals, and supplements, buying from Life Extension is well worth the extra cost. I just called Life Extension and the nutrition specialist assured me that the ingredients do NOT come from China, the ingredients are made in the US. I just called again the same number from Ft. Lauderdale and the lady I talked to confirmed that the raw materials come from China, but she said that they go thru.
