Need help how long is this supplements opened shelf life?

I've had this chicken elixir from strong animals since the third month of 2022 which I opened the day I got it, it's just been sitting lid closed in a room that stays in the 70s to 64°f range so it's not gotten super hot or cold.
Is it safe to use still? I need to open it and see what it looks like. Im thinking it will be fine but it would be nice to hear others opinions and experiences with this stuff.

I have ducks that free range with my chickens and drink from the same bowls I believe the chicken elixir stuff is safe for them too but I'm not sure.

I tried searching it a bunch but couldn't find an answer on how long it's opened shelf life is I really wanna try using it and see if it helps my flock breath easier

I really appreciate any advice

Safety is not the issue with opened vitamins. The issue is that time degrades the potency levels of the nutrients. Rule of thumb is nutrients in a dry form take longer to degrade than nutrients in liquid form. I'd say it would be good for a few years, but a little less effective. It won't hurt poultry, though.

I just got some pictures of the stuff in the lid and in a bowl.

So based on these I think it seems okay. I think it has a few dry pieces from the neck of the bottle and such, some of the dried up liquid seems white looking.
