Could I give this to my 18 month old daily?

My husband is sick and I have a bit of a sore throat, I reallllly do not want him getting sick - especially we’re going to the doctor tomorrow for his needles so I want to try to avoid him getting sick.

I’m just wondering if it would be safe to give him this let’s say once or twice a day until my husband and I are better?

I’m also going to the store to buy fresh oranges, apples, carrots, etc. To make homemade juice to give to my little one! I’m so so nervous with everything going around.
