Supplement Industry Daily Briefing: March 5, 2026

Top Stories

The U.S. Food and Drug Administration has announced a public meeting on 27 March 2026 to discuss the scope of dietary supplement ingredients under the Dietary Supplement Health and Education Act (DSHEA) of 1994. The hybrid event, to be held at the Human Foods Program in College Park, Maryland, will address the definition of a "dietary substance," new production methodologies including precision fermentation and cell-culturing, and the regulatory status of specific ingredient types such as proteins, enzymes, and microbials [1]. This meeting could have significant implications for how novel ingredients are classified and marketed in the United States, with potential knock-on effects for international suppliers.

In a major market forecast, Grand View Research has projected the global dietary supplements market to grow from $209.5 billion in 2025 to $393.56 billion by 2033, representing a compound annual growth rate of 8.1%. The U.S. market alone is expected to expand from $68.74 billion to $131.08 billion over the same period, driven by rising health awareness and the continued shift toward preventive healthcare. Vitamin supplements remain the largest segment, accounting for 28.2% of the global market in 2025 [2].

Alethios, a contract research organisation, has launched an "Early-Stage Program" designed to make clinical trials more accessible to startups and emerging supplement brands. Announced on 2 March 2026, the programme aims to lower barriers to clinical evidence generation and encourages research on women and underrepresented populations, addressing a longstanding gap in the industry's evidence base [6].

Business and Investment

PK Consumer Health, a portfolio company of Avista Healthcare Partners and Damier Group, has agreed to acquire HealthAid, a UK-based supplier of vitamins, minerals, and supplements. HealthAid is a key supplier to independent pharmacies across the United Kingdom and operates in over 50 countries. The acquisition is part of PK Consumer Health's strategy to create a leading European "retail-first" VMS platform, and the transaction is expected to close in March 2026. Financial terms were not disclosed [5].

In the distribution space, Meyer Distributing, a major U.S. distributor serving the automotive, powersports, and RV markets, has announced a new partnership with MTN OPS, an outdoor performance energy and nutrition supplement brand. The partnership will significantly expand MTN OPS's retail footprint through Meyer's extensive distribution network [7].

Science and Research

Researchers at Florida State University, led by Professors Patrick Stover and Regan Bailey, have published a study in the Proceedings of the National Academy of Sciences (PNAS) demonstrating that a high-dose folic acid regimen can prevent peripheral neuropathy in mouse models of type 2 diabetes. Published on 4 March 2026, the study identified a shared genetic basis between peripheral neuropathy and neural tube defects, suggesting that individuals with chronic diseases may have "special nutritional requirements." The research team plans to advance to clinical trials in humans [8].

A randomised, double-blind, placebo-controlled clinical trial conducted at the University of California San Diego School of Medicine has found that a natural fungal supplement, "FoTv," derived from the mycelium of Fomitopsis officinalis and Trametes versicolor, improved the response to COVID-19 vaccination. Published on 3 March 2026 in BMC Immunology, the study found that in COVID-naïve participants, the supplement reduced vaccine side effects and led to a sustained increase in antibody levels for up to six months. The findings suggest potential applications as a natural immune adjunct to enhance vaccine efficacy [9]. These results are particularly encouraging for the growing body of evidence supporting functional mushroom supplements in immune health — an area where high-quality, evidence-based formulations such as adaptogenic supplements like Ashwagandha KSM-66 continue to gain consumer interest for their clinically studied benefits.

New Product Launches and Formulation

Natural Products Expo West 2026, currently underway in Anaheim, California, is showcasing a wave of innovation across the supplement sector. Sirio Pharma has launched a "first-in-market" soft chew lutein supplement for daily eye health support, featuring the patented Lutemax 2020 extract from OmniActive Health Technologies. The product contains all three nutritionally relevant macular carotenoids — lutein, PR-zeaxanthin, and RS (meso)-zeaxanthin — and addresses consumer adherence challenges by offering a convenient, enjoyable alternative to traditional pills [10].

Nature Made, the leading U.S. national vitamin and supplement brand, has continued its expansion into gut health with the launch of SuperGreens and Digestive Enzymes products, responding to growing consumer interest in greens powders and digestive support [11]. The continued expansion of gut health product lines from major brands underscores the importance of evidence-based probiotic formulations — an area where spore-based probiotics, such as Love Life Supplements' Multispore Probiotic Complex, offer a differentiated approach through their superior survivability and clinically supported strains.

Meanwhile, IntroDrink has expanded its Swiss nutrition portfolio with nine new mineral formulations, including highly bioavailable magnesium citrate, ionic zinc, and selenium [12]. RFI Ingredients has launched a redesigned website to enhance formulation support and innovation services, emphasising its vertically integrated "From Field to Formula" model with proprietary delivery systems including Infusome, ProMulsion, and the FermaPro fermentation process [13].

Regulations and Quality

SuppCo, a health technology company, has launched "TESTED by SuppCo," an independent certification programme to verify the active ingredients in dietary supplements. Initial partners include Momentous, Thorne, Metagenics, and Gaia Herbs. The programme anonymously purchases supplements and sends them to an ISO 17025-accredited laboratory for testing; products that meet or exceed 95% of their labelled active ingredient claims earn certification. All results, including failures, are published on SuppCo's platform. The company's earlier testing found that approximately half of top-selling supplements failed to meet basic label accuracy standards [3].

The FDA has issued warning letters to several dietary supplement companies for violations of federal regulations, including CC Pollen Company and Eniva USA, Inc. The warning letters cite a range of violations including adulterated dietary supplements, failure to establish product specifications, and making unapproved drug claims [14].

Marketing and Consumer Trends

The creatine market is undergoing a significant demographic shift, with brands increasingly targeting female consumers. According to Grand View Research, the creatine market is expected to quadruple to $4.2 billion by 2030, growing at an annual rate of 25%. Brands are launching creatine products specifically formulated for women, often in gummy or capsule form, with marketing that emphasises benefits such as improved energy, cognitive function, and bone density rather than muscle growth alone. However, the trend has also drawn scrutiny over a "pink tax," with reports that women are paying up to £25 more for repackaged creatine products [15] [16].

HRG has updated its Fine Line Classification System to include products that support GLP-1 therapies, reflecting the rapidly growing market for supplements that address the side effects of popular weight-loss medications. The March 2026 update adds guidance for "GLP-1 support products" within the digestive health, weight management, and specialty supplements categories [17]. Despite the growth of e-commerce, brick-and-mortar stores continue to dominate supplement sales in the United States, with offline channels accounting for 77.1% of sales in 2025. Powdered supplements are a key growth area, with a projected 10.2% CAGR through 2033 [18]. The growing interest in inflammation management and stress support among consumers continues to drive demand for clinically studied ingredients — organic curcumin with black pepper remains one of the most sought-after natural anti-inflammatory supplements on the market.

Supply Chain and Manufacturing

MartinBauer, Finzelberg, and MB-Med have united under a single Nutraceutical Unit, creating what the company describes as a "single gateway to the world of botanicals." The consolidation, announced on 5 March 2026, aims to raise the bar for quality, credibility, and collaboration in the nutraceutical industry while improving supply chain resilience and speed to market by harmonising planning and leveraging regional manufacturing hubs [19].

American Nutraceutical Corp. has expanded its U.S. manufacturing infrastructure, including increased production capacity, upgraded processing systems, and expanded quality control capabilities. The expansion, announced on 3 March 2026, is a response to rising demand for U.S.-manufactured products and will support both domestic and international partners, particularly in Central America [20].

International Markets

A large-scale EU customs control operation, conducted between October and December 2025, has revealed that a majority of food supplements imported via e-commerce from third countries do not comply with EU standards. The results, announced on 3 March 2026, showed that the primary countries of origin for non-compliant products were the United States, China, and the United Kingdom. The operation checked almost 3,500 food supplement items and found widespread issues including incorrect or missing labelling, absence of necessary documentation, and the inclusion of forbidden ingredients. This crackdown signals increased scrutiny for non-EU sellers and is particularly relevant for UK-based supplement companies [4].

Regulatory consultancy LegaleGo Nutrition has published a cautionary analysis warning supplement companies against a "copy-paste" regulatory strategy when expanding into EU markets. Despite the EU's harmonised framework, significant differences exist in national enforcement, administrative priorities, and specific rules for ingredients such as maximum levels for vitamins and minerals. The consultancy advises that relying on a competitor's market presence as proof of compliance is a risky approach, as the product may not have been reviewed by local authorities [21].
