Vitamins for Freddi (ball python)?

[MD_Pythons]

Garters and diamond pythons do better when provided with UVB -- and I think some people (at least in this garter FB group I'm in) add calcium supplements to their garter food. That might only be if/when they're feeding worms, though. Garters are weird lol. Most snakes seem to bask more when provided UVB, but that's mostly anecdotal. Corn snakes have scientifically shown a rise in D3 levels with given access to UVB. So, I wouldn't say they don't 'require' sunlight... just that it's possible for them to survive without it, if that makes any sense.

Is there a study or anything on that for Diamond Pythons? I've been looking into them, the cooling and the price of entry is a bit daunting but it's always cool to read about them.
Edit: While anecdotal, I did hear that Bredli's showed brighter coloration when exposed to UVB. I have one of of those Zoo Med double domes on my IJ's tank so I may throw a UVB on a timer and see if it affects her behavior.
