Taurine's 1.5–3 g Sweet Spot: What 34 Trials Found on Sugar and BP
Taurine is best known for its anti-aging buzz, but a new meta-analysis of 34 randomized trials looked at everyday health markers instead. Supplementation was linked to lower fasting glucose, HbA1c, triglycerides, cholesterol, blood pressure and inflammation. The benefits clustered at 1.5–3 g per day, and the duration findings were surprising: glucose and lipids improved most after 8 or more weeks, while blood pressure and inflammation looked better in shorter trials. The effects are modest and the trials were varied, so here is what the paper does and doesn't show, and who might want to be cautious.
NMN and Blood Pressure: 10 Trials Pooled, Over-60s Dropped Most
A new meta-analysis in Nutrients pooled 10 randomized trials of NMN, the popular NAD+ precursor, to see whether it affects blood pressure. Across 349 participants, NMN modestly lowered diastolic pressure by about 2.15 mmHg, while the overall systolic change was not significant. In adults 60 and older, systolic pressure dropped by roughly 3.94 mmHg. But the sample is small, the analysis used a common-effects model, and the authors call the evidence preliminary. Here is what the numbers mean, what they don't, and why NMN is no substitute for blood pressure medication.
