Is elderberry gummies better for my kids health or multivitamins instead?

So I been giving my kids (2 & 5) vitamins everyday I use the zarbees elderberry gummies

But I’m not sure if elderberry has bad effects from them long term use. So my question is which one is better on keeping my kids healthy

I been paranoid with covid and I want to try my best to protect them. I know there’s still a percentage but I still want to try my best .

So which one will be better to keep them healthy from these viruses, Elderberry vitamins or multivitamins?

Also here’s the photos & the ingredients in them

And these are the multivitamins

Edit: so I have asked my children’s doctor but they don’t really give me an answer, they just say either one is fine, but I asked which one is better but they don’t have an answer so that’s why I’m here 😕
