It means Advanced TRS is zeolite free from heavy metal contamination found in naturally occurring zeolites. This gives you peace of mind that your zeolite are 100% pure and free of harmful contaminants.
Nano-particle sized means that Advanced TRS is EXTREMELY small in size. What this does is increase the surface to volume ratio, meaning that less does more – there’s more surface area to interact with contaminants in the body.
Also this small size allows it to be encapsulated to a water molecule so it can readily pass the Blood Brain Barrier.
