What about this?Liver retinol accumulates with age, and so does serum retinol. This is plainly demonstrated by the London autopsy data and the NHANES survey.
In the case of the thyroid, I don't think it would be harmful because I have seen no evidence for this. As far as I can tell, this had all started from the misinterpretation of carotenemia's relationship with hypothyroidism.
Seems based on observation of patients.In general, carotene behaves as an inert substance dependent on the lipids for its movements in the body and having no effect upon the body's economy except as a precursor of vitamin A. However, excessive ingestion may in some cases be followed by certain toxic effects, which are similar to those arising from excessive vitamin A ingestion, but are due to carotene and not to vitamin A.
