I'm looking to order the Denstra as well. I found it on
www.entirelypets.com however I'm looking for the hepato support too, so I've been searching to try and find a place that carries both. No luck so far. Entirelypets lists the ingredients as:
---
Each 1 Enteric Coated Tablet Contains: SAMe 200mg
Inactive ingredients: Mannitol, citric acid, cellulose, stearic acid, sodium starch glycolate, croscarmellose sodium silica, enteric coating (glycerol triacetate, hydroxypropyl methylcellulose phthalate), titanium dioxide
Not sure if this helps you or not : )
