What are purines, and why do they keep being mentioned with uric acid? Purines are natural substances in your body tissues and in many foods. When your body breaks them down, it makes uric acid.
Three simple takeaways
1. Purines come from the body and food
Purines are not only something that comes from what you eat. They are also present in your own body tissues. Old cells are naturally broken down, and purines from those cells are part of that process. Purine-containing foods can also add to the purines your body breaks down.
2. The body turns purines into uric acid
Uric acid is a waste product made when purines are broken down. It dissolves in the blood and is carried around the body before it is removed.
3. The kidneys help it leave the body
Most uric acid is filtered from the blood by the kidneys. It then leaves the body in urine. If the body makes more uric acid than it removes, uric acid can build up. This does not cause health problems for everyone, but in some people it can form crystals in joints.

The main point
Purines are normal substances from both the body and food. Uric acid is the waste product made when they are broken down.
