Drinking more coffee was linked to different hormone levels in 2,264 adults, but it wasn't shown to cause those changes. The Finnish study looked at people aged 46; 47% were men. Researchers compared daily coffee intake with blood tests and body measurements. They studied men and women separately. They also accounted for smoking, activity, alcohol use, education, and body size. More coffee was linked to higher SHBG (Sex Hormone Binding Globulin) in both men and women. This is a protein that carries sex hormones in the blood. The source did not report how much higher it was per cup. In men, each extra daily cup was linked to 0.29 nmol/L higher Total Testosterone, a blood-level measure. Yet Free Testosterone, the portion not attached to proteins, was lower. Women also showed lower levels of this unattached portion with more coffee. Their other hormone links were more limited. People drinking more coffee also had less total body fat. They had lower Visceral Fat, the fat around internal organs. These findings add context, but don't show that coffee improves health. This was a snapshot, not a test of changing coffee intake. It cannot show whether adding a cup would change someone's bloodwork. Longer studies and tests of coffee habits are still needed. For BioSocial members, the useful takeaway is to compare hormone results together. One higher number doesn't mean every hormone measure moves upward. Logging daily cups alongside bloodwork could add context when comparing notes with the community. What have you noticed in your hormone results during periods when your coffee habits changed?
