Dietary supplement recalls have remained a closely watched issue in 2026 as FDA investigations continue to trace contamination risks tied to moringa-based products sold online across the U.S. The latest case involves Zen Principle Moringa Capsules, a supplement sold from Nevada and distributed nationwide through major e-commerce channels. For shoppers in the United States, the immediate issue is narrow but specific: one lot of the product has been recalled and the affected bottles can be identified by the code printed on the bottom.
One lot of Zen Principle capsules is now under recall
Relay Peak Research LLC, doing business as Zen Principle Naturals in Incline Village, Nevada, announced a voluntary recall on July 19, 2026, for one lot of its Zen Principle brand Moringa Leaf Powder Capsules after the company said an ingredient supplier notified it that FDA testing found Salmonella in moringa leaf powder used to make the product. According to the FDA-posted company announcement, the recall applies only to Lot A6FF4 with a Best By date of 11/2028.
The affected product was sold in a plastic bottle containing 180 capsules. The company said the recalled inventory was also offered as a 1-pack identified by Amazon FNSKU X000ZJJ4FT and as a 2-pack, or 360-capsule twin pack, identified by Amazon FNSKU X00159YJXP. No other Zen Principle products are included in this recall, according to the FDA notice.
As of the July 19 announcement, no illnesses had been reported. The company said consumers who purchased the affected lot should stop using the capsules and dispose of them, and it stated that buyers do not need to return the product in order to receive a full refund. The FDA recall page lists the event under foodborne illness and identifies the reason for the announcement as possible Salmonella contamination.
What the nationwide online distribution means in the U.S.
The confirmed distribution area is broad: the FDA-posted notice states that the recalled capsules were distributed nationwide from December 2025 through July 2026. Unlike some recalls that identify grocery chains or store-level shipment records, this one was sold primarily online through Amazon and the company’s own website, with one unit also sold on eBay and one on Etsy, according to the FDA notice.
Because the product was distributed nationwide rather than through a short list of brick-and-mortar outlets, the company has not released a state-by-state or city-by-city breakdown of where the recalled bottles were delivered. That means there is no public list naming specific locations in California, Texas, Florida, New York, Illinois, or other states, even though consumers in any state may have purchased the supplement online during the distribution window.
For readers, the identifying details matter more than geography at this stage. The product name is Zen Principle Moringa Capsules, the package size is 180 capsules per bottle, and the lot code to check is A6FF4 with a Best By date of 11/2028 printed on the bottom. The company said customers seeking refunds or information can contact Relay Peak Research directly by phone or email, while the recall itself remains posted on the FDA’s recalls page.
The recall fits a broader 2026 moringa contamination pattern
The stated cause in this case is supply-chain contamination. Relay Peak Research said the recall began after its ingredient supplier notified the company that FDA testing of the moringa leaf powder used in this single finished lot returned positive for Salmonella, and the company said it has stopped all sale and distribution of the product while cooperating with the FDA.
The recall also arrives during a year of broader FDA scrutiny involving moringa supplements. In an FDA outbreak update published in July 2026, the agency said it had been investigating multistate Salmonella illnesses linked to products containing moringa leaf powder, with earlier recalls involving other brands and lots. FDA reporting on that outbreak said the agency and CDC had worked with state and local partners as investigators traced contamination through the supply chain.
For customers, the practical takeaway is limited to the recalled lot and the company’s disposal guidance. The FDA notice does not list a recall classification number or enforcement report number for this event in the materials currently public, and it does not provide a state-by-state distribution list. What is confirmed is that Zen Principle’s recalled lot A6FF4 should not be used, the bottles do not need to be returned for a refund, and no illnesses had been reported as of July 19, 2026.
