I bought this package for my father. It benefited his immunity greatly. He is very satisfied and has more energy. Size is good, it lasted him for 2 months, he is only now on the second bottle.

Easy to swallow. Hopefully, this works for enhancing killer cells but I didn’t see any difference in my blood work. I probably didn’t take it long enough.

Easy to swallow with no aftertaste. As with other supplements, don’t expect immediate results

I believe that they work
Verified purchase
I've been taking the Life Extension NK Cell Activator for a few years now and decided to switch over to the KAL brand, mainly because of price and the slightly different ingredients. I've been using the NK Cell Activator, in conjunction with curcumin, to help with keeping my cancer tumours under control. I have been through chemo three times, but given I was told to expect 2 years maximum of life back in 2016, I can cope with the chemo every 2 years or so. I do believe that the NK Cell Activator has played a major role in my overall, pretty good health and quality of life so far.
