Aim for an estradiol level of approximately 60 pg/mL (generally achieved with a 0.05 mg patch) during menopause to optimize long-term heart and bone protection, ideally starting within 10 years of the cessation of periods.

The analysis by Piette et Simon (2026) skillfully cross-references data from rigorous clinical trials (RCT) such as KEEPS and ELITE to identify this 60 pg/mL threshold, which offers a fascinating perspective on female longevity. Science strongly validates the 'window of opportunity' concept: initiating hormonal support before age 60 or within 10 years post-menopause shows clear protective effects on vessels and bones in these randomized controlled trials. However, targeting a specific number via regular blood tests is not yet validated by global research. Expert consensus reminds us that blood hormone levels fluctuate naturally and that benefits are measured primarily by felt well-being rather than a number on paper. Furthermore, while the protective effect on bone structure is widely recognized, the use of hormonal support solely for heart prevention is not yet validated by health authorities, due to a lack of direct evidence regarding the reduction of major cardiac events. It is, therefore, a captivating scientific signal that paves the way for future personalization, even if it precedes current recommendations.
