What Do You Use?

When people ask “What do you use?” about health, they usually mean something specific: which remedy, supplement, tool, or routine do you actually rely on? There is no single answer because the question covers everything from a headache to a blocked nose to a daily vitamin. What follows is an honest look at what common health products are actually for, what the evidence shows, and where the honest answer is “we don’t know yet.”

What Do You Use for a Common Cold?

There is no cure for the common cold. The viruses that cause it — most often rhinoviruses — have no antiviral treatment approved for general use. What you can do is manage symptoms while your immune system clears the infection, which typically takes about a week to ten days.

For a blocked nose, saline nasal rinses have reasonable evidence behind them. They physically flush mucus and irritants out of the nasal passages. Decongestant sprays containing oxymetazoline work quickly but should not be used for more than three days in a row, because longer use can cause rebound congestion — a frustrating cycle where the nose becomes more blocked when the spray wears off.

For aches and fever, over-the-counter pain relievers like acetaminophen or ibuprofen are widely used. These treat symptoms, not the virus. They do not shorten how long you are sick.

What about vitamin C and zinc? The evidence is mixed. Some studies suggest zinc lozenges started within the first day of symptoms may slightly shorten a cold, but results vary and zinc can cause nausea and a metallic taste. Vitamin C taken regularly does not appear to prevent colds in most people, though it may modestly reduce duration in people under heavy physical stress, such as marathon runners or soldiers in extreme conditions. For an average adult, the benefit is not well established.

What Do You Use for Minor Pain?

Two main over-the-counter options dominate: acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen. They work differently.

Acetaminophen reduces pain and fever but has little anti-inflammatory effect. NSAIDs reduce pain, fever, and inflammation. That difference matters depending on what hurts. A sprained ankle with swelling may respond better to an NSAID. A simple headache may respond equally well to either.

Both carry real risks. Acetaminophen overdose is a leading cause of acute liver failure in the United States, and it can happen when people accidentally take multiple products that all contain acetaminophen — cold medicines, sleep aids, and pain relievers often do. NSAIDs can irritate the stomach lining and, with long-term use, raise the risk of stomach bleeding and kidney problems. They are generally not recommended for people with certain kidney conditions, stomach ulcers, or those taking blood thinners.

This is one area where the honest answer is: follow the label, do not stack products, and talk to a pharmacist if you take other medications.

What Do You Use for Sleep Problems?

Good sleep habits — consistent bedtimes, a dark cool room, limiting screens and caffeine late in the day — are the foundation, and they are better supported by evidence than most sleep supplements.

Melatonin is the most commonly used sleep supplement. It is a hormone your body already makes to signal that it is time to sleep. The evidence is strongest for jet lag and for shift work, where it can help shift your body clock. For general insomnia, the evidence is weaker and results are inconsistent. Melatonin is not a sedative; it does not knock you out the way a sleeping pill does.

Prescription sleep medications exist, but most are intended for short-term use. Many carry risks of dependence, daytime drowsiness, and, in older adults, falls and confusion. This is a conversation to have with a doctor rather than something to manage indefinitely on your own.

What Do You Use for Heartburn and Acid Reflux?

Three categories of products are commonly used, and they work in different ways.

• Antacids neutralize stomach acid already present. They act fast but wear off quickly. Good for occasional, mild heartburn.
• H2 blockers reduce how much acid your stomach produces. They take longer to work than antacids but last longer.
• Proton pump inhibitors (PPIs) block the acid pumps in the stomach lining and are more effective for frequent or persistent reflux. They are often used for a set course rather than indefinitely.

Frequent heartburn — more than twice a week — deserves a medical evaluation rather than long-term self-treatment. Chronic reflux can damage the esophagus over time, and symptoms that mimic reflux can sometimes signal other conditions. PPIs are generally well tolerated, but long-term use has been linked in some studies to concerns like nutrient absorption changes and certain infections. The evidence on those long-term risks is not fully settled, which is why ongoing use is best discussed with a clinician.

What Do You Use for Everyday Nutrition Gaps?

For most healthy adults eating a varied diet, a multivitamin is not necessary. Food provides nutrients in combinations and forms that supplements do not always replicate, and the evidence that multivitamins prevent chronic disease in well-nourished people is weak.

That said, some supplements have clear, well-established roles for specific groups:

• Folic acid before and during early pregnancy reduces the risk of certain birth defects. This is one of the most firmly established supplement recommendations in medicine.
• Vitamin B12 for people following a vegan diet, and for many older adults, who absorb it less efficiently.
• Vitamin D for people with limited sun exposure or documented deficiency. Routine high-dose supplementation in people who are not deficient has not shown clear benefit in large trials.

For pregnancy, breastfeeding, infants, and children, dosing is a separate matter. Established guidance exists for some nutrients, such as folic acid in pregnancy and vitamin D for breastfed infants, but for many other supplements no clinical guidelines currently exist for these groups. Do not guess at doses for a child or a pregnant person.

What Do You Use When You Want to “Boost Immunity”?

This is where marketing runs far ahead of evidence. There is no product that has been shown to “boost” the immune system in a healthy person in a meaningful, measurable way. The immune system is not a single dial you can turn up.

Many supplements — echinacea, elderberry, garlic, various mushrooms — are marketed for immune support. For most of them, the human trial evidence is limited, mixed, or absent. That does not mean they are dangerous, but it means the confident claims made about them are not backed by strong data.

What genuinely supports immune function is unglamorous: adequate sleep, regular physical activity, not smoking, managing chronic conditions, and staying current on recommended vaccines. Those have far more evidence behind them than any supplement bottle.

What Do You Use to Decide What’s Worth Trying?

A few questions cut through most health product claims.

First, is there a clear mechanism and human evidence, or only a plausible-sounding story? Biological plausibility is not the same as proven benefit. Something can make sense in theory and still fail in trials.

Second, who is making the claim? A company selling the product has an interest in you believing it. Independent research and regulatory bodies carry more weight.

Third, what is the risk? Some supplements interact with medications, affect blood clotting, or stress the liver or kidneys. “Natural” does not mean risk-free. St. John’s wort, for example, interacts with many prescription drugs.

Fourth, is this treating a symptom or masking a problem that needs a diagnosis? Persistent symptoms deserve a doctor, not another over-the-counter product.

The most honest answer to “what do you use?” is often: the simplest thing that addresses the actual problem, backed by evidence where it exists, and a medical visit when symptoms persist or worsen.
