What people think is “vitamin A toxicity” is actually a sign of iron toxicity in the liver, due to copper deficiency. What happens is that when you get vitamin A from your diet, whether it's cod liver oil, beef livers, or free-range eggs, the retinol is converted to retinyl palmitate and stored in your liver cells.

To work properly, retinyl palmitate must be converted back to retinol so that it can be transported in the protein transthyretin (TTR), made up of T4 and retinol. Without retinol, TTR begins to be destructive. Although Robbins can't prove it yet, he is convinced that copper is required to convert retinyl palmitate to retinol.
