Horses grazing high oxalate pastures can lose calcium even when total calcium intake appears adequate. Australian research has shown that blood calcium levels may remain normal while parathyroid hormone (PTH) rises and calcium is mobilised from bone, a process that leads to bone demineralisation, and over time, osteoporosis.

This is why calcium form, bioavailability and utilisation matter, not just how much calcium is fed. Simply adding lucerne or standard supplements is often not enough on oxalate‑rich diets.
