Optimal levels of vitamin D

The patient said that his endocrinologist had told him some “pearls” about health and medicine. So I decided to comment on the basis of them. Read, analyze and form your own opinion:
1️⃣ There are receptors for the hormone progesterone even in the thyroid, vocal cords, liver, lungs, peritoneum, nasal mucosa and even in the central nervous system, i.e. not just in the reproductive organs, in both men and women. This shows that it has actions in these places: Do these receptors become totally inactive and useless with advancing age, post-menopause or removal of the uterus? What is the logic of depriving women of progesterone replacement if the tests and clinical picture indicate deficiency? Doesn't hormonal imbalance, such as only partial hormone replacement or the absence of modulation, cause or aggravate symptoms and diseases?
2️⃣ About vitamin D, I explain its importance and other aspects in https://icaro.med.br/vitaminad/. It's worth noting that the majority of people in the world are deficient in vitamin D3 and don't produce or replenish what they need. Studies show that the ‘ideal’ levels of vitamin D3 wrongly cited by the doctor (below 30 nmol/l) are linked to an increase in illness and mortality from various causes, including cancer. To name just a few studies: ar.iiarjournals.org/content/36/3/1379 e ncbi.nlm.nih.gov/pmc/articles/PMC4103214/.”
3️⃣ If progesterone is often called a ‘female hormone’, as some people mistakenly claim, why is it found in every man? God doesn't make mistakes: in other words, it also plays an important role in men, affecting circulation, breathing, brain function and the health of the sexual organs, among other aspects.
