Grenadine in crested mixture

[Brock]

I have used grenadine (that red sweet syrupy stuff) in my last two batches of crestie smoothies. They seem to like it, I read the ingredients and nothing jumped out at me that would say it's dangerous for herps:

Glucose - Fructose, water, citric acid, natural and artificial flavour, sodium citrate, sodium benzoate, colour.

The colour and artificial flavour are the only two things that would caution me, but I find that it sweetens the smoothies quite nicely, whereas honey tends to glob up and just stick to the side or bottom instead of mixing in.

Should I stick with grenadine or go back to melting honey in the microwave?
