Madisongrrl,

It is very dangerous to overdose on Cod Liver Oil and organ meats.

eg. Liver of bear has vitamin A in dangerous amounts. 1 gram contains Vitamin A that wud suffice for 2 years. Ingesting this amount even inadvertently can be dangerous. It will cause hypervitaminosis A.

There is no treatment for Vitamin A toxicity. Even small toxic amounts take months to deplete from your body.

Vit D3 supplements can be taken by properly monitoring it. I am against Vitamin A supplements. There is no definite test for Vitamin A. There is a test but that is not correct. It shows wrong values.

It is good to get Vitamin A from papaya ,cantaloupe ,milk and veg dietary sources.
