The label says vitamin a from Beta carotene. Which means that body takes the beta carotene and converts to Vitamin A as needed...so I don't think that would be an issue.
I use this drug interaction checker - and when I plugged in Vitamin A with minocycline - it came up as 'major'
But, beta carotene was okay.

into that checker. IF in doubt, then don't take the shake.
