Orthosilicic acid

Orthosilicic acid is a big word for something that is very small. Have you ever heard of sand or rocks? Well, they are made up of tiny things called silica. Orthosilicic acid is a type of silica that is dissolved in water, kind of like when you put sugar in your tea and it dissolves into tiny particles that you can't see anymore.

Some people take orthosilicic acid as a supplement because it is believed to be good for their skin, hair, and nails. It is also thought to help protect bones and joints. But scientists are still studying orthosilicic acid to see if it really does all the things that people think it does.

So basically, orthosilicic acid is a type of silica that is dissolved in water and some people take it to help their skin, hair, nails, bones, and joints, but it's not yet clear if it really works.
