In school, we talked constantly about polypharmacy, the use of multiple medications at once, sometimes on purpose but far more often by accident. A person ends up on five, eight, or eleven prescriptions, and somewhere along the way no single provider is looking at the whole list. The most insidious version even has its own name, the prescribing cascade, where the side effect of one medication gets mistaken for a brand-new problem and treated with another medication, which brings its own side effects, which invite yet another prescription. The list grows, the original question gets buried, and the person at the center of it rarely feels better for it.
It's a real, well-documented problem. But what we're not talking about nearly enough is that the same thing is happening with supplements.
Call it poly-supplementing. It even has a clinical name, dietary supplement polypharmacy, and once you start looking, it's everywhere. I reviewed a supplement routine recently and found three separate products that each contained iodine. Not one of them said "iodine" on the front. It was tucked inside a multivitamin, a women's hormone support blend, and a thyroid-support blend. Three doses, stacked, with no one keeping count.
And no, you don't just "pee out the extra." That's one of the most persistent myths in wellness. Some nutrients are stored, some compete with each other for absorption, and some, iodine very much included, can push the very system you're trying to support in the wrong direction when there's too much on board. More supplements does not equal better results. Taken without a clear purpose, they may actually worsen the symptoms you started taking them for.
"More supplements does not equal better results. The goal was never a fuller cabinet; it was a body that has exactly what it needs and nothing it doesn't."
So how do we take this seriously without throwing the baby out with the bathwater? Because supplements aren't the enemy. Used intentionally, the right one, in the right form, at the right dose, for an actual reason, they can be genuinely supportive. The goal isn't to dump the whole cabinet. It's to know what's in it, and why.
How I Decide Whether a Supplement Earns Its Place
Here's the same process I walk through when I'm helping someone decide whether a supplement is worth taking.
Start with your foundations. Before anything new goes in the cart, it's worth asking whether the basics are in place: balanced, protein-rich meals, real hydration, seven or so hours of sleep, and some honest attention to stress. Even the best supplement can't override blood sugar swings, chronic stress, or ongoing depletion, and your foundations are what decide whether a supplement works at all.
Let your symptoms and labs lead. Your energy, digestion, cycles, skin, mood, and cravings are data, and they point toward where something may be running low. If you have recent labs from your PCP or OB, things like ferritin, B12, folate, vitamin D, a thyroid panel, and blood sugar markers, look especially at the results sitting in that low-normal, borderline range, because those can still affect how you feel.
Try food first. Before you spend the money, ask whether you can realistically get enough of this nutrient from food most days: omega-3s from salmon and sardines, magnesium from leafy greens and pumpkin seeds, iron from beef and lentils. If the answer is yes, start there. If the answer is genuinely no, or you need a therapeutic amount, then a supplement may make sense.
Mind the form, not just the name. This is where most stacking goes wrong. The form on the label matters enormously. Magnesium glycinate is calming and supports sleep, while magnesium citrate mostly supports digestion. Methylated folate is more usable for many women, and vitamin D pairs with K2 for proper utilization. Before you add anything, read the full ingredient list and confirm that nutrient isn't already hiding in two other products you take. (This is exactly how three iodines end up in one routine.)
Choose less, on purpose. Wellness is an investment, but it shouldn't be overwhelming or financially stressful. Rather than five things at once, choose one or two that support your biggest symptoms or your deepest foundations, and give them a real chance to work.
Insist on quality. Look for third-party testing, clear dosing rather than hidden "proprietary blends," and forms that match what the research actually supports. "Natural" doesn't automatically mean effective, and the cheapest option often costs you in other ways.
A Quick Gut-Check Before You Buy
If you want a simple way to pause before your next purchase, ask yourself: Do my foundations support this working? Do my symptoms or labs suggest I need it? Can I get it from food first? Is this the right form and dose? Have I made sure the ingredient isn't already in something I take? Does it fit my budget? Is there real research behind it? Have I run it by my provider? If you can confidently say yes to those, you're probably making a thoughtful choice. I've gathered all of this into a free supplement guide you can keep on hand for your next purchase — grab it over at Intention Holistic Health.
That last question deserves its own emphasis, because it's the single best thing you can do for your future self: disclose everything. When you see any healthcare provider, bring the full ingredient lists, not just the brand names or "a multivitamin and a probiotic," but the actual labels. So much of what looks like a mystery symptom becomes obvious the moment someone can see that iodine, or vitamin A, or B6, or magnesium, is showing up in three places at once.
And if you'd rather not sort through it alone, and you're in Kentucky or Texas, you can reach out for a supplement review with me. We'll look at everything you're currently taking, sort out what's actually earning its place, and clear out what might be working against you. You don't need more. You need the right less. Here's how to work with me.
