I have Mast Cell Activation Syndrome. After decades of looking for answers down one rabbit hole after another, EMF was the last unexplored space. Since EMF causes the immune system to become agitated, and mast cell degranulation has a huge role in the immune system (plus many other biochemical processes), it made sense to explore the role of EMF in mast cell dysfunction. I was a hopeful skeptic, but moment we activated the C1 unit, all doubt went out the window; it created an immediate, palpable change. Every day since has seen improvement in my condition. I can now be exposed to the chemical stew present in public spaces without triggering a debilitating mast cell “degranulation event.” I literally got my life back. I’d made as much progress as I could with lifestyle changes and stabilizing nutraceuticals. C1 was the final piece of the puzzle.

C1 has been a game changer for my household. I could tell the difference within the first week of plugging it in. Super cool technology and incredibly beneficial in this day and age! The portables are much needed as well as I have used them everyday when leaving the house and can tell the difference.

I bought this bundle and I havent experienced tachycardia, since I started using it. I was experiencing it when my EMS meter showed high levels of radiation. I live close to a 5 G anthena and some times they rise the frecuencies, and I experience things like gum bleeding.
I don’t leave home without the portable one. Thank you!

I’ve had my eyes on the C1 ultimate bundle pack for a couple years now. I’ve had it for 5 weeks now, the most noticeable difference is my sleep.
I used to stay up till 2-3am just because I found it so hard to fall asleep. I tried sleeping pills, melatonin and turning off any blue light at a certain time and nothing really helped. Que blue shield.
Since having my blue shield, I can go to bed whenever I want. Falling asleep within minutes. (I never thought I’d be this person) ultimately I invested in this for my long term health, as EMF radiation can have devastating effects that might not be seen for years or decades. I feel blessed to have crossed paths with this technology & company

Recently purchased the C1 Ultimate Bundle Pack and so far have been satisfied with my purchase. Wife and I noticed a difference in our sleep. Looking forward to continuing using the Blushield products. Thank you for a great product!
