Looking for bland vitamins for under-3s

[Jasminetree]

We are keen to give our 2.5 year-old vitamins to make sure he gets enough vitamin D (Scottish cloud cover being what it is). I have tried two brands already of liquid vitamins, but he really dislikes sweet foods, and even diluted in a cup of water he finds them too sweet. Does anyone know of any blander vitamins, nut-free?

We use Dalivit in their milk, they haven't noticed it in there.

Abidec isn't sweet and they only have to take 0.6ml. My daughter loves it (weirdo) I think it tastes revolting!

Thank you both so much, I have bought some Dalivit, and will see if I can sneak it in to the wee one's milk. If not, I will investigate Abidec.

Abidec is nut based. But Dalivit gets hidden well in milk in our house.

Abidec has peanut oil I think
