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.

The older we get, the more we forget: names, appointments, why we walked into a room. For many, these little lapses are harmless. But they can stir fears of something more serious, like dementia. As a result, it's no surprise that grocery aisles and pharmacies are packed with pills claiming to sharpen memory, boost focus, or delay mental decline. Americans now spend billions on brain supplements every year.
The promise is compelling. With aging populations and no definitive cure for Alzheimer’s, the idea of an over-the-counter pill that could protect the brain is appealing. Scientists have explored a wide range of compounds, from basic vitamins to exotic plant extracts, to see whether they can preserve mental function. So far, the results suggest a mixed picture, with modest promise in some areas and little impact in others.

Caffeine isn’t just about alertness. New research reveals its surprising effects on brain health, insulin sensitivity, cancer risk, and all-cause mortality. But the benefits depend on how much and when you consume it and your unique biology.

Sleep is one of the most crucial pillars of high performance, yet in the relentless pursuit of success, many patients at Instalab wonder: Can you train your body to need less sleep while maintaining peak health and cognitive function? Some claim that adaptation is possible, but research tells a much different story. While short-term sleep restriction can be managed, long-term reduction without consequences is largely a myth.

Adderall edges out Ritalin on potency and duration. Ritalin edges out Adderall on tolerability. That's the core tradeoff the research keeps landing on, and it's a closer race than most people assume.
Both medications are stimulants, both are considered first-line treatments for ADHD, and both markedly outperform placebo on behavior and school performance in head-to-head pediatric trials. The differences between them are real but modest, which means the "better" choice almost always comes down to your specific situation: your age, your daily schedule, how sensitive you are to side effects, and how your body responds.

Acetylcholine is one of the most widely used chemical messengers in your body. It does not just relay signals between brain cells. It shapes your attention, helps you learn, regulates your heartbeat, calms your immune system, and even influences how your gut lining holds itself together. When this single signaling system breaks down, the consequences range from the cognitive collapse of Alzheimer's disease to chronic inflammation and psychiatric illness.
What makes acetylcholine (ACh) unique is the sheer breadth of tissue it touches. Neurons use it. But so do immune cells, epithelial cells lining your organs, and the endothelial cells inside your blood vessels. Understanding this "cholinergic" system, named after its central molecule, helps explain why so many seemingly unrelated conditions share a common thread.

No clinical trials have found that taking Lexapro (escitalopram) at one time of day works better than another. Every major study for anxiety simply used once-daily dosing without specifying morning versus evening as important to how well the drug works. What the research does focus on, and what actually matters for your results, is getting the right dose, sticking with it long enough, and taking it consistently.

Research pooling data from over 12.8 million people shows that higher adherence to Mediterranean-style eating significantly reduces your risk of dying from cardiovascular disease, developing type 2 diabetes, and even experiencing cognitive decline.
The morning meal is your first opportunity each day to tap into these benefits. This article will help you understand what actually counts as a Mediterranean breakfast, why it works at the biological level, and how to make it practical for your life.

Naps have long been recognized as a countermeasure to sleep deprivation. And for many patients at Instalab who burn the midnight oil regularly, a nap can feel essential just to make it through the day. However, the science on whether napping is truly beneficial for sleep health and longevity is more nuanced than it might seem.
