My sister says she wont take them shes tried. Niece has become vegetarian shes 14 and pale and lethargic but it could be a teenage thing? Shes been staying with me and i dont know if its just that she's been on a holiday diet of picnic food but ive noticed its all carbs. Shes already been to the gp because of her low hb but has no interest in real proper veggie food shes so fussy. Would it be over stepping the mark if i get her sone vits with added iron?
