NADMar 15, 2026
If you've scrolled past ads for NAD "drip bars" or heard a podcaster rave about NAD infusions for energy and anti-aging, you're not alone. Clinics now charge hundreds of dollars per session for intravenous NAD+, promising everything from sharper thinking to slower aging. But almost all of the promising research on NAD+ boosting comes from animal studies or small human trials using oral supplements, not the IV injections being sold at wellness clinics. Direct IV NAD+ in healthy humans is scarcely studied.

Magnesium sprays are everywhere right now. Scroll through any wellness feed and you'll see claims about better sleep, fewer cramps, and "near 100% absorption" through your skin. It sounds appealing, especially if swallowing pills isn't your thing. But the clinical evidence does not support magnesium sprays as an effective way to raise your body's magnesium levels. The research consistently points to oral supplements and food as the reliable options.
Lab TestingMar 15, 2026
Understanding your lab results is crucial to making well-informed health decisions. Traditional reference ranges, based on average values of a healthy population, define normal upper and lower limits for lab tests. While useful, these ranges can fall short in actually detecting the early stages of disease and extending lifespan and healthspan. This gap is addressed by the concept of 'peak health' ranges, which provide a more nuanced, individualized, and proactive approach to health management.
Cancer ScreeningMar 15, 2026
Full-body MRI, sometimes marketed as a "preventive" or "executive" health scan, has become one of the hottest trends in proactive health care. The pitch is simple and appealing. But what does the research actually say about whether it is worth it for you?
For the average healthy adult, current evidence does not support routine full-body MRI screening. The scan finds confirmed cancers in only about 1 to 2% of people without symptoms, while triggering uncertain or false-positive findings in roughly a third of everyone scanned. For people with specific high-risk genetic conditions, the picture is very different, and the scan can be genuinely lifesaving.
