Can Russian Tortoises eat Purslane?
Portulaca oleracea
Safety verdict
Caution
Why
[confidence: high] [source: The Tortoise Table plant database entry for Portulaca oleracea; exotic reptile veterinarian review specializing in chelonian nutrition.] Purslane (Portulaca oleracea) is edible for Russian Tortoises and offers beneficial omega-3 fatty acids, but it contains moderate-to-high levels of soluble oxalates which can bind dietary calcium and contribute to metabolic bone disease or kidney issues with frequent feeding.
How much / how often
Offer occasionally as a minor dietary supplement, no more than once or twice per month, and never as a dietary staple.
Preparation
Serve fresh and raw; avoid wilted or decomposing material. Pair with high-calcium greens such as dandelion or endive to help offset oxalate impact.
