Spore-based probiotics are built to survive stomach acid, bile, heat, and storage more reliably than many conventional probiotic organisms. That is a real advantage, but survivability alone does not make a probiotic clinically superior. Traditional Lactobacillus and Bifidobacterium strains have decades of human research behind them, while selected Bacillus strains have increasingly good clinical evidence of their own. The useful question is not which category wins. It is which strain has evidence for the job you want it to do.

Probiotics contain live microorganisms. Postbiotics contain intentionally inactivated microorganisms, their components, and sometimes the compounds produced during fermentation. Both can influence human physiology, but they are not interchangeable, and neither category is automatically better. The strain, preparation, dose, clinical purpose, and human evidence matter far more than the label.

One of the deepest biological studies ever performed on a supercentenarian found something unexpected: she carried unmistakable signs of extreme aging while remaining remarkably free of the diseases we normally associate with it. The lesson may not be how to stop aging, but how to remain resilient to it.

Many of the deadliest “ovarian” cancers actually appear to begin in the fallopian tubes. Removing the tubes during another appropriate surgery may dramatically reduce risk while preserving the ovaries and their hormone production.

ER-100 has moved partial epigenetic reprogramming from animal research into a first-in-human trial. Here is what OSK reprogramming has shown, how the experimental gene therapy works, what researchers are testing in glaucoma and NAION, and why this is not yet evidence that human aging can be reversed.

GlyNAC supplies glycine and NAC so the body can manufacture glutathione, while glutathione supplements provide the molecule directly. Human studies support both approaches, but the evidence is more nuanced than longevity marketing often suggests. Here is what the clinical research shows about benefits, dosing, absorption, safety, and healthy aging.

Glutathione and N-acetylcysteine are often sold as competing antioxidant supplements, but they do different jobs. Glutathione supplies the molecule directly, while NAC supplies cysteine the body can use to make its own glutathione. The better choice depends on why it is being used, the person's nutritional status, tolerance, and whether direct or precursor support makes more sense.

HormoneSynergy Clinic was recently invited to refer its “members” to an outside peptide and weight-management company in exchange for an additional revenue stream. There was just one problem: we are a medical clinic, not a gym, which strongly suggests this same pitch is being made to gyms and other non-medical businesses. More troubling than the mistake was the business model itself.

The thymus has long been treated as an organ that largely fades into irrelevance after childhood. A large 2026 Nature study challenges that assumption, linking better thymic health in adults with lower mortality, cardiovascular death, lung cancer risk, inflammation, and metabolic dysfunction.

Your gut microbiome is an active biological ecosystem involved in digestion, immune signaling, intestinal barrier function, metabolism and communication with the brain. Learn what the science actually shows, what shapes the microbiome, where probiotics and prebiotics fit, and what microbiome testing can and cannot tell you.

Researchers are learning how to identify biological aging in dogs before the gray muzzle and slower walk make it obvious. As the youngest member of the HormoneSynergy household, I have reviewed the evidence and discovered that Dr. Retzler, Daniel and I are working from a surprisingly similar longevity plan.

The vagus nerve does far more than help the body relax. It carries information between the brain and internal organs, plays an important role in gut-brain communication, and participates in neuroimmune pathways that can influence inflammation.
