To ask for teen vitamin recommendations

[Averysmallcasserole]

I have a nearly teenager who is pale presently. He’s had a few viruses over winter but fine in himself, still playing sport and eating like a horse, though not always the best food at school so I’m thinking he might benefit from a vitamin but want something he’ll take. What do you give, if anything?

I think you can get vitamins specifically for teens. Wellteen maybe

Thank you. It’s a minefielc. I have seen various but wondered if anyone had one they really rate or have seen a difference with
DH says he’s not pale but he is and he’s inside more these days so a little support (plus some amends to diet by me too) might help
