Supplement executives fanned out across Capitol Hill on June 10 for CRN’s annual Day on the Hill, anchoring conversations around three priority bills: the Cramer-Curtis Dietary Supplements Access Act for HSA and FSA reimbursement, Senator Durbin’s S. 3677 Dietary Supplement Listing Act, and Rep. Langworthy’s H.R. 7366 Regulatory Uniformity Act, which reaffirms FDA as the single national regulator. Tariffs, supply chain resilience and FDA’s oversight modernization track filled out the agenda, leaving the industry positioned to push for a unified DSHEA-aligned package before the August recess.

FDA published an expanded recall on June 3 after Total Nutrition, Inc. of Deer Park, NY added another lot of TNVitamins and Doctor’s Pride Ultra Potent Complete Green Superfood Moringa Capsules, distributed through Walmart, Amazon, Target and TikTok Shop. A supply chain traceability review identified a common raw material from lots 2507199 and 2512-304. The CDC count now stands at 119 illnesses and 32 hospitalizations across 36 states, sharpening FDA’s ongoing push for validated kill steps for raw botanical inputs under cGMP.

The EU, Australia and Canada are tightening upper intake limits and label warnings on vitamin B6 supplements amid renewed concerns about peripheral neuropathy at sustained high doses. Australia will move B6 above 50 mg into pharmacist-only channels starting June 2027. FDA’s Human Foods Complaint System logged 98 serious B6-related adverse events between 1999 and 2025, including 39 in 2024 alone, while industry groups dispute the dose threshold at which harm actually begins. Expect this to become an early test case for FDA’s oversight modernization framework.

Announced at Probiota Americas in Vancouver, the Weston Family Foundation’s new Microbiome Innovations for New Therapies (MINT) program will deploy C$37 million over seven years to advance microbiome-based interventions with credible preclinical data into clinical trials. It is the foundation’s largest granting envelope to date in a space it has funded since 2017. The investment reinforces a clear category-wide pattern: capital is flowing to the science that DSHEA-aligned brands will increasingly need to cite when substantiating structure/function claims for probiotics, postbiotics and prebiotics.

Function Health closed its acquisition of SuppCo, folding the independent TrustScore rating system, ISO 17025 laboratory-verified TESTED by SuppCo program, and a catalog spanning 35,000 products and 500,000 user routines into Function’s biomarker testing and clinician-guided platform. The move builds the most credible end-to-end loop yet between diagnostic data and supplement selection, and will pressure DSHEA-compliant brands to substantiate not just label claims, but how products actually move biomarkers in real-world consumers.

The week-in-review roundup ties three otherwise separate storylines into one strategic picture: a C$37M microbiome therapy push from the Weston Family Foundation, coordinated international vitamin B6 restrictions, and a new Chinese Five-Year Plan signal favoring functional marine ingredients including algae, krill and chitosan derivatives. Together, the items map where capital, regulation and ingredient innovation are all heading, with direct read-through for U.S. NDI strategy and brand positioning in the second half of the year.

Probiota Americas closed out at the Westin Bayshore in Vancouver with Day 2 sessions on longevity, immunosenescence, phages, prebiotics and microbiome-led weight management, and the unveiling of the 2026 Probiota Pioneers cohort (ClostraBio, Holobiome, Kioga). The agenda lines up cleanly with the Cramer-Curtis HSA/FSA push and FDA’s oversight modernization track, illustrating how the next wave of supplement innovation is being prepared for both clinical substantiation and DSHEA-compliant commercialization.

With the Cramer-Curtis access bill, the Durbin listing proposal and the Langworthy uniformity bill all live, the next several weeks will determine whether the industry can secure a unified DSHEA-aligned package before Congress breaks for August. Constituent voices that reach Senate and House offices now have outsized leverage.
