I take vitamin d, whole vitamin c, turmeric, zinc, quercetin, and elderberry gummies for immune health and haven’t gotten sick except for a 24 hour stomach bug since I started it. My 1 and 3 year old get sick pretty regularly though and I want them to be better at fighting it off.

My 3 year old gets an elderberry gummy for kids that has a little zinc and I’m planning to also add in vitamin-d drops. There don’t seem to be many vitamin supplements for babies though and I’d like to be able to also give something to my 1 year old. Anyone have any suggestions for research they can point me to?
