I am doing a pelletless diet but according to research guinea pigs need some vitamin D so calcium goes into their bones, not soft tissues.
Do the ingredients in this look ok? I of course would give a much lower dose.
Nordic Naturals - Vitamin D3 Vegan, Healthy Bones, Mood, and Immune System Function, 1 Ounce (FFP
Does anyone know approximately how much vitamin D a day is recommended?
