Hi everyone, as my dad ages I keep thinking I should get him on a vitamin regimen to slow his ageing/help him feel better.

He eats healthy but I can tell that he doesent feel %100 anymore and he just had a surgery which dident help.

it seems his circulation in this hands etc has become much less in his older age which i guess is normal but i want to do what i can.

What would you recommend a senior to take in the way of vitamins?

Thanks for any help.
