My family and many of my friends have been using Life Extension supplements and reading their materials for 25 years.
We've had nothing but positive experiences. Having people who are chemists among us, they have checked LE's supplements over the years and have found them to be very pure and the ingredients as claimed.
As far as how much money LE takes in, I would hope the company would take in a lot and that it would pay its leaders (and employees) very good salaries, because they deserve it. From standing up against an Eastern European-style Stasi to designing supplements that fit the latest research, LE's leaders do an excellent job. They are the bravest of all soldiers in the fight for access to high-quality supplements.
As far as troubles with the organization that would love to take control of supplements, the FDA, Life Extension has beat them in the courts several times by using evidence to prove their cases.
E.g., LE introduced to Americans in the early eighties, after which they were raided by the FDA who claimed it was a toxic substance. LE fought them with the evidence showing that it was not and that it was a worthwhile supplement, and we now have access to one of the best substances ever discovered.
There must be 2000 positive studies on CoQ10. LE will supply a ton of them to anyone who wishes.
As far as what one of the reviewers above said about their sources not even being relevant to their articles, that is pure poppycock. I'm a speed-reader and read oodles of studies on vitamins, minerals, and herbs, and LE provides the best articles of any I read.
Granted, the health food industry puts out a lot of fanciful propaganda trying to promote new cure-alls, but you absolutely cannot put LE in that same category.
If you don't believe me, then check LE out for yourself.
Bottom Line: Yes, I would recommend this to a friend
