Vitamin D matters for bone and deficiency, but routine high-dose supplements are not a proven longevity strategy and can cause harm in excess.
CGMs Without Diabetes: Useful Signal, Not a Diet Plan
CGMs can reveal glucose patterns, but for adults without diabetes the evidence is early, noisy, and not a stand-alone reason to change diet.
Menopause, Oestrogen, and Muscle Loss: What We Know
