My grandmother started taking the supplement a few days after her first chemo infusion of T/C on May 2nd. Prior to taking the supplement she had some fatigue and a minor nausea but once she started taking the supplement her energy levels returned to normal and there was no more nausea. Her blood count results also held steady at her follow up appointment on May 9th. I will wait to see if the supplement prevents side effects all together (as I can’t say definitively if my grandmother would have bounced back so soon even without the supplement) after her next infusion later this month but so far I can say that taking the supplement has not hurt as my grandmother’s energy levels, appetite, taste buds, etc. are all the same. Wishing you all health and long life on your journey to being and remaining cancer free!

I was impressed with how quickly the product arrived and it seems to be of a good quality. As I have only just started to use it I will wait before giving a more detailed response.

Relief From Serious Chemo Side Effects

I want to thank LifeBiotic for Protectival. I am a breast cancer patient currently undergoing the T/C regimen of chemotherapy.
I was diagnosed years ago with chronic respiratory failure, and the toxic effects of the chemo after 3 infusions had caused me to have serious difficulty breathing, necessitating my use of oxygen 24/7.
My first order of Protectival arrived 4 days after the latest treatment, and I began taking it immediately. I was also suffering from all the other more common toxic side effects, and was utterly miserable.
I noticed an improvement in those miseries within hours – but the most remarkable effect was an easing of my breathing difficulties. After 4 days, I was off the oxygen for most of the day. After 2 weeks, I am immensely better – for the most part, just on oxygen at night, as I was before the chemo.
I cannot thank you enough – nor can I recommend it highly enough to anyone who might be considering purchasing it. Also worth reading on are the various scientific papers which detail all the other benefits of Protectival.

To me, Protectival is not just a supplement, but a life saver. It helped me gain back my strength, my health and my hope.
