Colloids are made by separating the nanoparticles and charging them negatively (‒) so that they repel each other and remain in suspension, but factors such as light and electrical components can interfere with the charge of the nanoparticles in suspension, since As they all have the same charge, they repel each other and when they change to charge (+) some nanoparticles will begin to unite with the (‒) ones, as if they were opposite poles of two magnets (+) until particles visible to the human eye are created and they are it will reduce its effectiveness of absorption into the body.
To solve this, you can filter the Colloidal with a simple coffee filter since only the particles visible to the human eye will remain in it and it will let the nanoparticles pass and return to having your colloidal as the same day you bought it.
