I got another customer concern letter regarding specific ingredients to the Hikari Mulberific - the cassava starch, and the apple and banana content, and Japanese spinach. . .
Hi Customer,
It's good to read ingredient labels. In short your concern is valid, but in this case, I think this food is a good commercial diet for small tortoises.
I grabbed this off of Google AI - "Japanese spinach (often komatsuna or Asian-leaf spinach) has thicker, crunchier stems and a milder, slightly sweet flavor compared to regular spinach. Komatsuna lacks oxalic acid, meaning it doesn't leave a bitter aftertaste or a filmy feeling on your teeth, and holds its shape much better in hot broths or stir-fries."
Oxalic acid is often considered 'bad' for tortoises due to the dogma (unjustified belief) that it causes gastrointestinal stones. There is zero evidence that occurs in tortoises. If you want, I can elaborate on that.
The cassava starch is a natural binder so the other mixed ingredients stay together, it is considered a safe alternative to gluten. All pelleted foods contain some binder. Cassava starch has no known negative impact.
As for the banana and apple they are flavor enhancers and do not push the fruit to an out of control level. The problem with fruit, which all tortoises eat some of, is that people don't know how to moderate. They see the tortoise likes it, so they overdo it. Repeated ingestion alters the gut microbiome significantly. I give most tortoises cactus fruit, and occasionally some berries; for example, a 50 pound tortoise might get three berries or a fig. That is a appropriate. Not like a small adult Hermann's getting several strawberries daily, that is grossly inapprorpiate.
I use the Hikari Mulberific with small tortoises. I sell it in my on-line store (best price in the US) and had an independent lab run an analysis to see if there were any residual herbicides or pesticides in it. It's clean. I can send you the lab result if you would like to see it.
These pellets produced by Hikari use mulberry as the primary (first) ingredient. I offer the hibiscus to create a cold brew tea to soak the pellets, for a different taste and color from one meal to the next. The back label is shown so you can read all the detail. This is relatively new product for n...
