Seems to work

En verdad funciona, buen producto, de esperar de la marca Life, muy satisfecho

Numbers are improved

I bought this supplement and the Senescence supp to boost my immune system. I had gotten sick 4 times in one year and usually never get sick. Thinking about aging (I am 64), led me to do some research. I can already tell that it is working due to my sometimes overactive lifestyle.

This supplement was purchased to assist/combat the symptoms of late diagnosed /chronic Lyme disease. Using this product in combination to antibiotic therapy and a Lyme healing lifestyle, within just a few months, CD57 results showed an NK cell increase from 11 to 55. Doctors were pretty amazed by the short turnaround/improvement to my NK cell counts. I do not know for sure what contributed to my epic health improvements but since this supplement was used in addition to the conventional and recommend treatments that most established Lyme patients already implement, i believe this supplement could be the reason I surpassed expectation and why my NK levels sky rocketed.

Life extension is a necessary supplement to my overall health!

As a MBC survivor I take this in hopes that it will keep the cancer at bay. The Oncologist at LEF recommends it.

I was told by my doctor to take this because I have a compromised immune system. Who knows if it works but I managed not to get several colds that my boyfriend brought home. So I'll keep taking it. Three stars because it's so expensive and packaging is deceptive. This big bottle is mostly filled with cotton. It's a waste of plastic.
