Your body adapts, dampening the effect you're seeking
For generations, the daily vitamin has been a quiet ritual of self-care — a small act of faith that consistency equals health. Now, a nutritionist is gently challenging that assumption, suggesting that the body's remarkable capacity to adapt may be quietly neutralizing the very benefits we seek. The practice of 'supplement pulsing' — taking vitamins intermittently rather than without pause — invites us to reconsider whether habit and health are always the same thing.
- The routine most people trust — a daily multivitamin with breakfast — may be training the body to resist the very benefits it's meant to deliver.
- Certain supplements carry real risks when taken continuously: vitamin D can stress the kidneys, Kava can damage the liver, and soy isolate may throw hormone levels off balance.
- Nutritionist Clairissa Berry argues that the body's drive toward equilibrium works against long-term supplementation, dulling effects that were once meaningful.
- The proposed fix is 'supplement pulsing' — cycling on and off to prevent adaptation and allow the body to reset between doses.
- Experts are urging people to treat supplements less like background habits and more like deliberate interventions, ideally designed with a professional and tracked through a personal health journal.
There is something quietly reassuring about the daily vitamin — a small, consistent gesture toward wellbeing. But a nutritionist is now raising an uncomfortable question: what if that very consistency is the problem?
Clairissa Berry, working with DIRTEA, explains that the body is always seeking balance. Introduce the same supplement day after day, and the body adapts, compensating in ways that gradually erode the supplement's intended effect. This is the logic behind 'supplement pulsing' — taking vitamins in cycles rather than continuously, giving the body time to reset rather than build tolerance.
The stakes are higher with certain supplements. Vitamin D taken in excess over time can damage the kidneys. Kava can harm the liver. Soy isolate risks disrupting estrogen levels. These are not obscure compounds — they are staples of many people's daily routines, taken without much thought about duration or cumulative dose.
Berry's broader point is that supplements, like medications, act throughout the body in ways that extend well beyond their stated purpose. The solution she recommends is not to abandon them, but to use them with more intention — working with a nutritionist or doctor to design a pulsing schedule, and keeping a journal to track how the body actually responds. In doing so, a mindless daily ritual becomes something more valuable: a genuine inquiry into what your own body needs.
You wake up, take your daily multivitamin with breakfast, and assume you're doing something good for your body. But what if that routine—the very consistency that feels responsible—is actually working against you?
A nutritionist is raising a counterintuitive point about how we approach supplements. The issue isn't that vitamins are bad. It's that your body, over time, adapts to them. When you take the same supplement day after day, your system learns to compensate, essentially building a tolerance. The result is that the supplement becomes less effective at doing what you originally took it for. It's a phenomenon called "supplement pulsing," and it suggests that the way most people use vitamins might need rethinking.
Clairissa Berry, a nutritionist working with DIRTEA, explains the mechanism plainly: your body is always trying to maintain balance. When you introduce a supplement regularly, your body adjusts in response, dampening the effect you're seeking. The solution, she argues, is to take supplements intermittently rather than continuously—on for a period, then off for a period—allowing your body to reset rather than adapt. This approach can serve two purposes at once: it may preserve the supplement's effectiveness, and it can reduce the risk of unwanted side effects that accumulate with long-term use.
But not all supplements are created equal when it comes to safety. Some shouldn't be taken continuously at all. Vitamin D, for instance, can damage your kidneys if taken in excess over extended periods. Kava, an herbal supplement, can harm the liver with overuse. Soy isolate carries the risk of disrupting hormone balance, particularly estrogen levels. These aren't rare edge cases—they're common supplements that many people take without thinking about duration or cumulative dose.
Berry emphasizes that supplements, like medications, have wide-ranging effects throughout the body, often beyond the single purpose someone is taking them for. That complexity means that what seems like a simple daily habit can have consequences that aren't immediately obvious. The recommendation, then, is not to abandon supplements altogether, but to be more intentional about how you use them.
The practical approach she suggests involves working with a professional—a nutritionist or doctor—to design a pulsing schedule tailored to your needs and the specific supplements you're taking. During both the periods when you're taking a supplement and the periods when you're not, you should pay attention to how you feel. Keeping a journal of any changes—positive or negative—can help you and your healthcare provider understand what's actually working and what isn't. It transforms supplement use from a mindless daily ritual into something more like an experiment, where you're gathering real data about your own body rather than assuming that consistency equals benefit.

So if I've been taking the same vitamin every morning for five years, am I wasting my time at this point?
Not necessarily wasting it, but your body has probably adapted to it. You might be getting less benefit than you were in the first year. That's the tolerance piece—your system learns to compensate.
But couldn't I just take a higher dose to overcome that?
That's where it gets risky. Some supplements, like vitamin D, can actually harm you if you take too much over time. Your kidneys can suffer. It's not just about effectiveness—it's about safety.
So the answer is to stop taking them altogether?
No. The idea is to pulse them. Take them for a set period, then take a break. Let your body reset. Then start again.
How do I know when to pulse and when to stop?
That's where you need guidance. A nutritionist can help you design a schedule that makes sense for your specific supplements and your health. And you should track how you feel during both phases—keep notes.
What if I don't notice any difference when I stop?
Then you have useful information. Maybe that supplement wasn't doing much for you anyway. That's the point of the experiment—to actually see what's working rather than assume.
