Patients who took widely available joint supplements marketed for arthritis relief ended up in clinics and emergency departments with hormone disruptions, abnormal lab results, and symptoms consistent with steroid overuse, according to a retrospective study at a safety-net primary care clinic. The products at the center of the findings, Artri King and Artri Ajo King, were later confirmed by the U.S. Food and Drug Administration to contain hidden prescription drug ingredients never listed on their labels. The cases add clinical weight to a growing body of evidence that over-the-counter arthritis supplements sold through major retailers can cause serious, sometimes dangerous side effects.
Hidden drugs in joint supplements triggered clinic visits
The core problem is straightforward: supplements that consumers believed were natural remedies actually contained potent pharmaceutical compounds. FDA laboratory analysis identified undeclared dexamethasone, a prescription corticosteroid, in Artri King products. Separately, the agency confirmed that Artri Ajo King contained undeclared diclofenac, a prescription-strength nonsteroidal anti-inflammatory drug, prompting a nationwide recall of various Artri Ajo King joint supplements by Walmart Inc.
Dexamethasone and diclofenac are not benign ingredients when taken unknowingly. Dexamethasone is a glucocorticoid that, with prolonged use, can suppress the body’s natural cortisol production, alter blood sugar, and weaken bones and muscles. Diclofenac carries risks of gastrointestinal bleeding, kidney injury, and cardiovascular events, especially with chronic exposure or in patients with underlying risk factors. Neither drug appeared on the supplement labels, so patients and their doctors had no way to account for the exposure when evaluating new symptoms.
A retrospective mixed-methods study conducted at a safety-net primary care clinic documented the clinical fallout. Researchers reviewed electronic health records and interviewed patients who had used unregulated arthritis supplements, including Artri King, and found a pattern of hormone abnormalities, adrenal suppression workups, and unexplained Cushing-like features. The clinic-based research reported abnormal cortisol levels and other complications consistent with hidden steroid exposure. Because these patients sought care at a safety-net clinic, many were from populations with limited access to specialty endocrinology follow-up, compounding the risk of delayed diagnosis and incomplete recovery.
Case reports trace adrenal crises back to Artri King products
Beyond the clinic-level study, individual case reports have traced specific endocrine emergencies directly to these supplements. A published case series described three patients who developed hypothalamic-pituitary-adrenal axis disruption after using Artri King. Their diagnostic workups revealed suppressed cortisol and ACTH levels, a pattern consistent with exogenous glucocorticoid exposure from the supplement. The clinical presentations matched what physicians would expect from a patient taking prescription steroids without medical supervision, yet none of the patients knew they were ingesting dexamethasone.
In another documented case, a patient arrived at an emergency department with gastrointestinal symptoms, weight gain, and facial swelling after using Artri Ajo King. Clinicians eventually identified iatrogenic Cushing syndrome, a condition caused by excess corticosteroid exposure, followed by adrenal insufficiency when the supplement was discontinued. Cushing syndrome can produce high blood pressure, fragile skin, mood changes, and increased infection risk. Adrenal insufficiency, which can follow abrupt withdrawal of steroids the body has grown dependent on, carries the risk of adrenal crisis, a potentially life-threatening drop in cortisol that can cause dangerously low blood pressure, vomiting, and shock.
These are not theoretical risks. The patients in the case reports required medical intervention, diagnostic imaging, hormone testing, and in some instances prolonged endocrine management. In several cases, clinicians had to prescribe physiologic steroid replacement and then taper doses slowly to allow the adrenal glands to recover. The clinical trail from supplement use to emergency presentation to confirmed steroid-related diagnosis was documented in each instance, underscoring how a product sold as a natural joint remedy functioned, in practice, like an unmonitored prescription drug.
Retail access outpaced regulatory detection
The gap between when these products reached consumers and when regulators acted is central to understanding why the side effects accumulated. Artri King and Artri Ajo King were sold through mainstream retail channels, including large national chains. Unlike prescription drugs, dietary supplements in the United States do not require pre-market approval from the FDA. Manufacturers are responsible for ensuring their products are safe and properly labeled, but the agency typically intervenes only after problems surface through adverse event reports, inspections, or outside research.
That reactive model meant patients were already experiencing adrenal suppression and Cushing-like symptoms by the time the FDA issued its public notification about Artri King and Walmart initiated the Artri Ajo King recall. The safety-net clinic study captured what happened in between: patients buying supplements they trusted, developing unexplained fatigue, swelling, or infections, and presenting to primary care providers who then had to work backward to identify the cause. In some cases, the connection to a joint supplement emerged only after extensive testing ruled out more familiar endocrine disorders.
Broader surveillance data offers context for the scale of supplement-related harm. National analyses of emergency department visits have estimated tens of thousands of annual encounters linked to dietary supplements, with weight-loss, energy, and sexual-enhancement products most often implicated. The Artri King and Artri Ajo King cases show that joint and pain-relief supplements can pose comparable risks when they are adulterated with powerful pharmaceuticals. Because these products are often marketed to older adults and people with chronic pain, the potential for serious complications is amplified.
Why hidden steroids are especially dangerous
Unlabeled corticosteroids in supplements are uniquely hazardous because their risks extend beyond the period of use. Even when patients stop taking the product, their adrenal glands may remain suppressed for weeks or months, leaving them vulnerable to adrenal crisis during illness, surgery, or injury. Without a clear record of steroid exposure, clinicians may not think to administer stress-dose steroids in emergencies, delaying life-saving treatment.
Hidden steroids also confound routine medical care. A patient taking dexamethasone unknowingly may have improved joint pain and inflammation, masking the severity of underlying arthritis and complicating decisions about disease-modifying therapies. At the same time, the drug can worsen diabetes control, raise blood pressure, and thin bones, undermining other aspects of chronic disease management. When exposure is unrecognized, these side effects can be misattributed to aging or disease progression rather than to a modifiable source.
Implications for clinicians and patients
The emerging evidence around Artri King and Artri Ajo King suggests several practical steps for frontline clinicians. Detailed medication histories should explicitly include over-the-counter supplements, especially in patients with unexplained endocrine findings, recurrent infections, or rapid changes in weight and appearance. When adrenal suppression or Cushing syndrome is suspected, clinicians may need to ask about specific brand names and, if possible, examine product packaging brought from home.
For patients, the cases highlight the limits of assuming that products labeled as natural, herbal, or vitamin-based are inherently safe. While many supplements are benign, some have been found to contain prescription drugs, stimulants, or other pharmacologically active substances without disclosure. Patients with chronic conditions such as diabetes, heart disease, or osteoporosis are particularly vulnerable to harm from hidden steroids or NSAIDs layered on top of their existing therapies.
Regulators, clinicians, and consumer advocates have called for stronger oversight of high-risk supplement categories, clearer pathways for reporting suspected adverse events, and better public education about the potential dangers of unregulated arthritis remedies. Until those changes are in place, the experiences of patients harmed by Artri King and Artri Ajo King serve as a cautionary example of how easily a product marketed for joint relief can trigger a cascade of endocrine complications when its true ingredients remain hidden.
