Hmm... I've been reading this thread, and I don't see the problem.
Sure a diet of pure Nutrobal would be a disaster, but, as I understand it with a ratio of 48:1, then it simply needs to be balanced out by phosphorous in other foods.
Follow me through this here:
As best my hasty research can tell me, a pinch is about 0.25g
Nutrobal is 1/5th calcium (200mg per gram according to the bottle)
so - each pinch of Nutrobal is about 0.05g
This means, bring the ratio back up to 2:1 one simply needs to include food that contains about 0.025 grams of phosphorous.
For the calculation above, I've disregared the phosphorous component in nutrobal as it is so small.
By the logic presented here, pure calcium would be harmful as well (with a ratio of infinity:1) ... which is true if it were the complete diet, but I can't see why it would be if used as a supplement.
Marie mentioned D3 - I'm not sure what that is yet, but will have a read when I get home later... that could be a whole other reason for not using it.
Further, it does look from my reading that it is better for them to get their calcium through regular diet rather than supplements (much like us bigger mammals) which makes perfect sense... but in a pinch (hah!) I still can't see why it should fail as a supplement.
For me the logic for using this seems sound (apart from D3?) because other reading and advice I've gotten suggests when it comes to calcium, better too much than too little - and Nutrobal can be thought of as close to pure calcium.
That being said, I have the feeling from another thread that we're about to have a dramatic diet change in this house soonish, and, I'm very much a beginner here (I've had my guys for a year or so), so I'd be mad not to defer to the advice of those with more experience, whatever my numbers tell me
