This page is information only and gives no doses. In the US, call 911 for chest pain, trouble breathing or a severe allergic reaction, and Poison Help at 1-800-222-1222 if someone may have swallowed too much of a product. See poisoning: what to do first. Check with a clinician before supplements if you are pregnant, give them to a child, are an older adult, have kidney or liver disease, take blood thinners or several medicines, or are having surgery.

What is offered

NCCIH lists herbs and other dietary supplements among the approaches used by naturopathic practitioners. [1] Supplements include vitamins, minerals, herbs and many other ingredients. Many practices also dispense products from their own shelves or online stores. For nutrient-by-nutrient facts, see vitamins and supplements and multivitamins.

Questions to ask

  • What is each product for, and what is the evidence for that use?
  • Do you earn money when I buy it? Can I buy it elsewhere?
  • Has the product been tested by a third party? See quality testing and certifications.
  • Could it interact with my medicines or surgery? MedlinePlus advises checking with your provider before surgery. [7]
  • How long should I take it, and what tells us it is not working?
  • What does the total plan cost? See costs and supplement sales.

Frequently asked questions

Does the FDA approve supplements before sale?

No. The FDA says it is not authorized to approve them for safety and effectiveness before marketing. [2]

Is it a problem if my practitioner sells supplements?

It is a conflict of interest to manage, not proof of bad care. The AMA code for physicians calls for disclosure. [6] Ask openly.

Can supplements contain things not on the label?

Some can. NCCIH says products sold as supplements may contain prescription drugs or ingredients not listed. [3]

Should I tell my doctor what I take?

Yes. MedlinePlus advises telling your provider about any supplements you use. [7]

Are supplements ever unsafe?

Yes. They caused an estimated 23,005 US emergency visits a year in a 2004 to 2013 study. [5]

More details: evidence, limits and cautions

The details behind this page: cautions, limits of the evidence and where sources disagree. Open any note to read it.

How supplements are regulated in the US
The FDA says it is not authorized to approve dietary supplements for safety and effectiveness before they are marketed. [2] NCCIH says the FDA can take action against adulterated or misbranded supplements only after the product is on the market. [3] The FDA says the firm that makes or distributes a supplement is responsible for making sure it is not adulterated or misbranded. [4] Rules in other countries are not described in the sources we read. See how supplements are regulated.
Quality and safety
NCCIH says products sold as supplements, mainly for weight loss, sexual enhancement and bodybuilding, may contain prescription drugs not allowed in supplements or ingredients not listed on the label. [3] The FDA says it has limited resources to analyze what is in supplements. [4] NCCIH also says supplements may interact with medicines or pose risks if you have certain conditions or are having surgery, and that many have not been tested in pregnant women, nursing mothers or children. [3] It says taking a multivitamin is unlikely to pose any health risks. [3]

Harm is documented. A national surveillance study estimated 23,005 US emergency department visits a year in 2004 to 2013 from supplement-related adverse events, and weight-loss and energy products were commonly implicated. [5] That study covers all supplements, not those dispensed by naturopathic practices. See product quality and contamination and reading supplement labels.

Cost and conflicts of interest
A practitioner who sells what they recommend has a financial interest in the sale. The American Medical Association's ethics code for physicians says selling health-related products raises ethical concerns about financial conflict of interest and undue pressure on patients. [6] It says physicians who sell should offer only products whose benefit claims rest on peer-reviewed literature or sound scientific review, fully disclose their financial interest, and say the product or an equivalent is available elsewhere. [6] That is one profession's code, and it is shown here as a model for your questions. Whether naturopathic or other professional bodies have similar rules is not described in the sources we read.

Proper evidence not found: how common practitioner supplement sales are in naturopathic practice, or typical markups. We searched PubMed for naturopathic supplement dispensing and conflict of interest, and the AMA code, and found no study that answers this. We give no prices.
