I think the point with nutritional supplements is that there may be a nutritional deficiency that is behind severe hormone deficiencies (beyond the normal redistribution at menopause).
Perhaps it's one of the reasons why some women ‘sail through' (if you'll forgive the overused analogy!), as opposed to the debilitating hell other women suffer through.
A friend has had 2 operations with a general anaesthetic and she has suffered from the post op night sweats. Her first op was a hysterectomy so we had assumed it was due to that (even though she kept her ovaries) but it happened again after a bowel op and research shows that it's caused by the hypothalamus kicking back in after the general wears off. As we know, doctors still do not understand the root cause of menopausal night sweats and this could be a similar event to what happens to the brain after anaesthetia
To bring my ramble back into context, if the body can produce the correct raw materials to produce a more balanced hormonal state, then perhaps nutritional supplements play a bigger role than we realise.
