You can also try turmeric..make a scrambled egg with turmeric in it..or try oats cooked with turmeric..that is also good for them..i believe even if they dont have any problem we should make it a habit to give them garlic n turmeric every now n then..i personally havent tried ACV..so cant say much about that..but the other two work wonders.
