Glucose tablets are a well-established treatment for low blood sugar (hypoglycemia), particularly in individuals with diabetes who take insulin or certain oral medications. These tablets deliver a precise dose of glucose, helping to restore blood sugar levels quickly and effectively. But how do they compare to other carbohydrate sources, and what does current research say about their reliability?
The best zinc lozenge trials show something genuinely impressive: colds shortened by roughly 40%, with triple the chance of being recovered by day five. That translates to about three fewer days of misery from a typical week-long cold. But here's the catch. Many of the zinc lozenges you'll find at the pharmacy are either under-dosed, formulated with ingredients that neutralize the zinc, or both. The difference between a lozenge that works and one that's dead on arrival comes down to details most people never check. A 2024 Cochrane review of 19 treatment trials found zinc may shorten colds by about 2.4 days on average, though the evidence was graded low-certainty with high variability between studies. That variability isn't random. It maps closely onto differences in dose, formulation, and how the lozenges were used.
If you've ever dealt with constipation, there's a good chance someone recommended docusate sodium. It's one of the most commonly prescribed stool softeners in hospitals and a fixture in drugstore laxative aisles. But here's the uncomfortable truth: the research consistently shows it doesn't work very well, if at all. Of nine studies directly examining whether docusate sodium effectively treats constipation, 89% concluded it does not. Major medical guidelines don't recommend it as a first-line treatment, and many hospitals are actively removing it from their formularies. So what should you actually use instead? This article breaks down what the research shows and what options are worth your time and money.
Topical minoxidil has been the go-to treatment for female pattern hair loss for decades, and for good reason: large randomized trials and meta-analyses consistently show it improves hair count and scalp coverage compared to placebo. But the more interesting development is what's happening off-label. Low-dose oral minoxidil, taken as a tiny daily pill, appears to work about as well as the topical version, with one randomized trial finding similar efficacy between 1 mg oral and 5% topical, and actually better improvement in shedding with the oral form. That said, minoxidil in any form is not a hair restoration miracle. It mainly slows shedding and modestly increases hair density over months. Expecting a return to teenage-level hair is setting yourself up for disappointment. Expecting to keep more of what you have, with some visible improvement in coverage over 6 to 12 months? That's what the evidence supports.
Most over-the-counter UTI products sit in a frustrating middle ground: genuinely helpful for prevention and pain management, yet unable to reliably clear an active infection on their own. Systematic reviews consistently show that antibiotics remain the gold standard for treating uncomplicated UTIs, delivering faster symptom relief and a lower risk of the infection spreading to the kidneys. The OTC options people commonly reach for, including ibuprofen, cranberry supplements, and D-mannose, each have a real role. That role just isn't "antibiotic replacement." What makes this tricky is that some of these products do reduce UTI recurrences in clinical trials, and a subset of women in studies using only NSAIDs did recover without antibiotics. So the picture isn't black and white. It's a question of which job you're asking the product to do, and how much risk you're willing to accept.
