Worth knowing about this bottle
Vitamin A with Vitamin D3 likely, not settled
A single human study found that a high dose of preformed vitamin A blunted the rise in blood calcium normally triggered by active vitamin D, suggesting the two can work against each other at high intakes. This was a small, acute study, not evidence about typical daily supplement doses.
What to do: Avoid combining very high-dose preformed vitamin A supplements with vitamin D therapy without medical guidance; ordinary multivitamin-level doses of both are not a concern.
