Immune booster

We use viral guard. You can buy either the liquid or the "fizzy chews" which are chewable tablets.

There is also Immune + by Medford which is also very good.

(I tend to alternate between the two depending on my mood)

Hi

I am looking for a good immune booster for my toddler when she starts creche. Are there any ones on the market that have been tried and tested?
