I cannot attest to the quality of Life Extension products. However, they are an extremely aggressive marketing organization that promotes their supplements through their Web site and once you purchase a supplement through their magazine, their magazine is automatically sent to all customers on a monthly basis and promotes high dosage supplements with references to articles in respected medical journals.
- The referenced articles and studies sometimes do not necessarily support their claims or even correlate the claims in Life Extensions magazine.
- Each article is accompanied by an authentic looking list of references that presumably substantiate the claims in Life Extensions magazine. Some of these references have nothing to do with Life Extension supplements as they appear to be just fillers
- The doses promoted by Life Extension effectively make their supplements drugs. I'm not talking about doses at the high end of most references. I'm talking about doses 2-3 times the max recommend by sites such as Mayo Clinic.
- At these doses, supplements can be contra-indicated with certain medicines. Life Extension NEVER advises customers to check on these potential high dose contra-indications.
Reasonable use of supplements may or may not be healthful. life Extensions recommendations for their supplements are neither substantiated anywhere except in their magazine nor are they necessarily safe.
Bottom Line: No, I would not recommend this to a friend
