Beware of supplements

6/13/2022

 

Updated September 4, 2026


Editor's note: This article is based on my experience and research. Everyone is different. Talk with your doctor or pharmacist before starting, stopping, or changing a supplement, especially if you take prescription or over-the-counter medications.

Dietary supplements are everywhere.

Many people living with chronic pain use vitamins, minerals, herbs, and other supplements hoping to reduce symptoms or improve their health. Some may be helpful for particular conditions or nutritional deficiencies. Others may provide little benefit, and some can cause harm.

The important thing is not to assume that a product is safe or effective simply because it is labeled natural or sold as a dietary supplement.

What you should know
  • Dietary supplements are not FDA-approved to treat or cure disease.
  • The FDA regulates dietary supplements differently from prescription and over-the-counter drugs. The FDA generally does not approve dietary supplements for safety and effectiveness before they are marketed.
  • Manufacturers are responsible for ensuring that their products meet applicable safety and labeling requirements.
  • Supplements can interact with medications and medical conditions.
  • Products can have unwanted side effects or contain contaminants or undisclosed ingredients.
  • Evidence varies considerably from one supplement to another. Some have been studied more extensively than others.
  • “Natural” doesn't necessarily mean safe.
  • More isn't necessarily better. Taking multiple products can increase the potential for interactions and side effects.

The FDA recommends talking with a healthcare professional before using dietary supplements, particularly because supplements can interact with medications or medical conditions.

Are supplements effective for chronic pain?
There's no simple yes-or-no answer.

Dietary supplements aren't one treatment. They include hundreds of different ingredients, and the evidence varies considerably.
Some supplements have been studied for particular types of pain, but evidence for many products remains limited or inconsistent. For example, a systematic review of randomized trials examining dietary supplements for fibromyalgia found evidence of pain improvement, but no significant improvement in quality of life, and the authors called for better-designed studies.

The important question isn't simply:
"Is this natural?" Ask: "What evidence shows that this particular product helps people with my particular condition?"

Can supplements become part of the pain cycle?
Sometimes, the issue isn't just whether a supplement works. It's the role it plays in managing pain.

If every increase in pain leads to another pill, product, treatment, or supplement, it's easy to become increasingly focused on finding something outside ourselves to make the pain better.

That doesn't mean taking a supplement is inherently harmful or that medication has no place in pain management.

It means it's worth asking: Is this treatment helping me become more confident and active in managing chronic pain—or am I becoming increasingly dependent on something outside myself to manage it?

Active self-management doesn't mean refusing medication or other treatments. It means developing skills and strategies that allow you to play an active role in managing chronic pain rather than relying entirely on treatments to do it for you.

My experience
As part of the Mayo Clinic fibromyalgia program I attended, I met with a pharmacist to review the long list of prescription medicines, over-the-counter medicines, and supplements I was taking at the time.

My medicine cabinet looked like a GNC store.

I was instructed to bring the actual bottles to the appointment, so I packed them into a gym bag and took them with me.

I was surprised as the pharmacist went through each bottle, making comments and recommendations about the products—including questions about product quality, labeling, ingredients, potential safety concerns, and dosing.

By the end of the appointment, my list of medications and supplements was much shorter.

She recommended that I stop most of the supplements I was taking.

My gym bag was much lighter.

That experience taught me an important lesson: More treatments don't necessarily mean better treatment. Sometimes the best approach is to step back, look at everything you're taking, and ask whether each one is actually helping.

Before taking a supplement
If you're considering a supplement for chronic pain, talk with your healthcare professional and consider asking:
  • What evidence supports using this particular supplement for my condition?
  • What benefits should I realistically expect?
  • What are the potential side effects?
  • Could it interact with my medications or other supplements?
  • Do I actually need it?
  • How will I know whether it's helping?
  • Is there a reason to stop taking it?

​A pharmacist can be particularly helpful when you're taking several medications and supplements.

The bottom line
Some supplements may be useful. Some may provide little or no meaningful benefit. And some can cause harm.

Natural doesn't automatically mean safe, and available without a prescription doesn't automatically mean effective.
Before adding another supplement to a chronic pain treatment plan, consider the evidence, potential risks, possible interactions, and whether you actually need it.

Most importantly, don't let supplements, or any other treatment, become your only strategy for managing chronic pain.

The goal isn't to find more things to take. The goal is to build the knowledge, skills, confidence, and strategies needed to live well while managing chronic pain.
