Why Track Purines Daily?
Purines break down into uric acid. When serum uric acid exceeds 6.8 mg/dL, crystals form in joints, triggering the intense pain of a gout attack (Dalbeth et al., Nature Reviews Disease Primers, 2019). Tracking what you eat is the first step most rheumatologists recommend. Read our complete purine guide for a deeper look at the science.
