Jeg orker dessverre ikke oversette, men i den blekka jeg fikk med meg hjem etter mitt besøk hos ham står det:

Problems arise where there has been an adrenal problem over enough time to interfere with thyroid T4 to T3 processing or receptor uptake. This is especially likely if you have been having thyroid supplementation (synthetic or natural). The effect of providing adrenal support is to allow greatly improved thyroid uptake and processing; enough to overload the system and the receptors with hitherto unuseable thyroid hormone.

Det står mer forklart om det i boken hans "The thyroid and how to keep it healthy", men den har jeg ikke her akkurat nå.

Hvor stort vitenskapelig belegg han har for sine uttalelser vet jeg altså ikke.
