Nutritional Supplement Marketing: Building Trust in a $481B Industry

The nutritional supplement industry's roots stretch back centuries, from ancient civilizations' herbal medicines to the discovery of vitamins in the early 1900s, which launched the first mass-market supplements. The 1960s-1980s saw the market dominated by bodybuilding culture—icons like Joe Weider and Arnold Schwarzenegger were some of the first celebrity influencers to tout protein powders and muscle-building supplements as mainstream products. 

Today, nutritional supplements are a $481 billion industry that has evolved far beyond its gym culture origins. In 2023, a consumer survey found that 74% of U.S. adults take supplements, whether to fill in gaps in their diets or health care availability, to enhance performance at work or during fitness activities, to enhance their appearance or to meet another wellness goal. 

The shift in focus from purely physical performance to holistic health has been driven by advancing science, changing consumer preferences and a growing focus on mental well-being, longevity and personalized nutrition—and of course fitness marketing.

The result is a complex marketplace where brands must navigate not just regulatory requirements but also unprecedented consumer demands for transparency, sustainability and proven efficacy.

Modern consumers seek sophisticated solutions that reflect a contemporary definition of wellness, one that spans functional foods, adaptogens and nootropics and clean-label formulations that deliver on their promises while aligning with their values. 

But here's the challenge: As competition intensifies and regulatory scrutiny tightens, supplement brands need more than attractive packaging and bold claims. They need marketing strategies that build trust, educate effectively and resonate authentically with an increasingly discerning wellness audience—all while staying compliant with shifting government regulations.

A Pivotal Moment for Supplement Regulation

Since the passage of the Dietary Supplement Health and Education Act in 1994, nutritional supplement brands have operated under a relatively flexible regulatory framework that allows them to market products without prior approval from the U.S. Food and Drug Administration, provided they do not make health claims, which would classify their supplements as drugs. 

Under DSHEA, brands can make structure or function claims—statements about how a particular nutrient affects normal bodily functions—such as “supports immune health” or “promotes cognitive function,” but they cannot make any claim to diagnose, treat, cure or prevent any disease or health condition. 

In the wake of COVID-19 and the rise of both anti-vaccine sentiment and alternative treatments, the FDA in particular has cracked down on brands that make unverified health claims. The same rules also apply to other wellness CPG and natural products, including cannabis, CBD and psychedelics. Functional product claims, for example, are also limited under cannabis advertising rules. Additionally, all claims must be substantiated and accompanied by the disclaimer that the FDA has not evaluated the statement. 

The Federal Trade Commission also plays a role in ensuring that supplement advertising is truthful and not misleading, particularly when it comes to online and influencer marketing. For instance, the FTC refunded nearly $550,000 to consumers who purchased a supplement based on misleading claims it would reduce alcohol cravings.

However, those regulations could be in flux following the appointment of Robert F. Kennedy Jr. as Health and Human Services Secretary. Coupled with the Trump administration's "Make America Healthy Again" agenda, many in the nutritional supplements industry anticipate sweeping regulatory shifts that could fundamentally alter how wellness CPG brands communicate with consumers.

Meanwhile, scientific and trade institutions like the Botanical Safety Consortium, the American Herbal Products Association and the Council for Responsible Nutrition are advancing new methods to evaluate supplement safety and efficacy, raising the bar for evidence-based claims.

Much like quality-minded brands in the cannabis industry have increasingly resorted to third-party testing that exceeds state standards for pesticides and other contaminants, supplement brands can distinguish themselves through transparency and surpassing regulatory requirements.

Nutritional Supplement Consumers: From the Gym Scene to the Disabled Community

Today's supplement consumers represent a demographic that extends far beyond the gym and can’t be pigeonholed. From biohackers optimizing cognitive performance to aging populations focused on longevity, CPG wellness buyers demand complete transparency. The era of trusting "miracle pills" has given way to educated skepticism and thorough research before purchase.

This evolution requires brands to develop omnichannel strategies that deliver consistent, credible messaging across direct-to-consumer platforms and retail partnerships. More importantly, it necessitates a fundamental shift in how brands communicate product benefits within an increasingly stringent regulatory framework. 

Disabled consumers represent a significant (and often overlooked) market segment in the dietary and nutritional supplements sector. Many disabled consumers seek products that support specific health needs, such as pain management, energy levels, digestive health and immune function.

These shoppers are often literate in medical jargon and scientific literature, and may seek solutions beyond, or in addition to, traditional pharmaceuticals. This segment is well-versed in self-advocacy and may be very frustrated with or ambivalent toward the medical establishment.

However, the nutritional supplements industry has faced criticism for marketing unproven or misleading “cures” to vulnerable populations, highlighting the need for stronger regulatory oversight and more ethical, evidence-based messaging. Moving forward, brands that prioritize transparency, accessibility and scientifically validated formulations will be better positioned to build trust and serve this diverse consumer group responsibly.

Science-Based Storytelling: The New Marketing Imperative

In the current environment, successful supplement marketing requires a delicate balance between compelling narratives and scientific rigor. Origin stories still matter—whether it's a founder's health transformation or a scientist's breakthrough discovery—but they must be backed by credible research and third-party validation. The most effective supplement marketing campaigns combine:

• Peer-reviewed research supporting ingredient efficacy
• Third-party testing and certifications (NSF, USP, Informed-Choice)
• Transparent sourcing and manufacturing practices
• Clear, compliant benefit statements that avoid overclaiming
• Educational content that empowers informed decisions

Much like shoppers have grown wise to greenwashing and greenhushing in their search for purpose-driven brands that match their values, today’s supplement buyers demand scientific validation, sustainability credentials and radical transparency. The era of blind trust in silver-bullet solutions is over. 

Modern supplement marketing must address heightened consumer skepticism and scrutiny while delivering value across multiple channels, from direct-to-consumer platforms to strategic partnerships. That’s why it matters to choose a marketing and PR agency partner that is well-versed in the ethical rigors of journalism, as well as how to deliver bold, creative messaging in complex business languages.

Authentic Storytelling Drives Supplement Success

In an industry often criticized for hype, authentic brand storytelling has become a crucial differentiator. Just like our agency’s work with cannabis and psychedelics companies, where we  navigate complex messaging challenges, we can support supplement brands by balancing scientific credibility with relatable storytelling. This approach mirrors our work in thought leadership and strategic communications, where authenticity and expertise converge.

The key is crafting narratives that resonate without overselling. Grasslands’ strategic development experience has shown that consumers respond best to transparent content that acknowledges both the benefits and limitations of a product—this is true B2C consumer and vendor education.

The Evolution of Influence

Celebrity endorsements from iconic bodybuilders helped nutritional supplements go mainstream. But today’s consumers don’t put the same trust or stock in fame that they used to. In the era of social media influencers, consumers are far more likely to trust word of mouth from authentic sources with plenty of EAT, which is short for Expertise, Authority and Trust. 

Cultivating and demonstrating EAT is one of the best ways to navigate regulatory messaging challenges. Reputable brands can create a sense of transparency that fuels invaluable social proof. Micro- and nano-influencers, healthcare professionals, registered dietitians and longevity experts who have cultivated EAT now lead the supplements conversation with educated, nuanced perspectives that resonate. 

This evolution mirrors Grasslands’ approach to media relations with traditional journalists, editors and producers, through which we prioritize genuine expertise and meaningful, good-faith dialogue over superficial reach. Through our extensive network of industry connections, we help brands identify and collaborate with credible voices that align with their values and enhance their authority in the marketplace.

Content Strategy: Building Authority Through Education

EAT is ultimately part of the search engine optimization best practices that have raised the bar for supplement marketing content. Successful brands invest in comprehensive educational resources that can be deployed across owned and earned media channels and have a strong foundation of SEO keywords and search phrases. In a related channel, email marketing has evolved beyond promotional blasts to become a sophisticated tool for nurturing leads and educating existing and potential customers.

Our digital marketing services help brands develop content strategies that not only satisfy search algorithms but genuinely serve their audiences' information needs. This includes:

• Research-backed blog content that addresses common questions and concerns
• Educational content featuring credible experts
• Downloadable resources and gated content that help consumers make informed purchasing decisions while also enhancing your sales funnel
• Email nurture campaigns that build trust over time
• Social media content that fosters community and encourages dialogue

 Looking Ahead: The Future of Supplement Marketing

One of our 2025 wellness CPG marketing predictions was that personalization will only continue to grow in popularity. As artificial intelligence continues to advance, so do the possibilities and demand for AI personalization and precision nutrition. While these powerful tools have a lot of appeal for brands and consumers alike, the fundamentals remain constant: transparency, scientific validity and values-driven storytelling are what differentiate winning brands. 

The supplement industry's future belongs to companies that understand they're not just selling products—they're partnering in their customers' wellness journeys and solving genuine consumer pain points. And the future of supplement marketing is intriguing, indeed:

• Personalized recommendation engines based on individual health data
• Augmented and virtual reality experiences that demonstrate product benefits
• Interactive educational content that adapts to user knowledge levels
• Community-driven content that leverages user experiences and results
• Integration with wearable technology and health tracking apps

At Grasslands, we're excited to help supplement brands navigate these emerging opportunities while staying true to the core principles of trust and transparency. Our integrated approach to PR and marketing combines cutting-edge strategies with time-tested practices to help brands thrive in this dynamic market.
