Inside the Formula | The Supplements That Cost Less When You Do It Right

With Designs for Health & TESTED by SuppCo: Inside the Formula is a new sponsored series featuring brands in the TESTED by SuppCo certification program, where we spotlight the fascinating research behind products that have received the certification. Learn more about TESTED by SuppCo.

Here is a sentence you probably did not expect to read today: Designs for Health existed for years as a chain of clinical nutrition clinics before it ever sold a single supplement to the public.

The origin story of Designs for Health is one the brand rarely gets to tell at full length, and it is the kind of story that explains everything about how the company operates today.

In 1989, Linda Lazaros, a clinical nutritionist, opened a nutrition and weight loss clinic in Westchester County, New York. The clinics multiplied. The team then hired graduate nutritionists, many trained out of the University of Bridgeport's master's program in human nutrition, which happened to be run by a researcher named Dr. David Brady. When those clinicians started asking for training on how to run successful practices and build evidence-based supplement protocols, they created Designs for Health to provide it. They were a clinical services and education company before they were ever a supplement brand.

The pivot to supplements came the way most meaningful decisions do: something stopped working.

The clinic practitioners had been relying on a handful of products, including what may have been an L-carnitine or CoQ10 formulation, and getting strong clinical results. Then… the results changed. In fact, they regressed. When they sent the products out for independent testing, it all of a sudden came back failing label specifications by a meaningful margin. This was pre-DSHEA, the era Brady describes plainly as the Wild West of nutrition. Rather than find another vendor and hope for the best, the company decided to take control. They began contract-manufacturing their own core products and, eventually, formulating entirely new ones. Quality came first not because it was a market differentiator, but because a failed product had cost their patients results.

Brady joined as Chief Medical Officer roughly 23 years ago, recruited by early formulator Robert Crayhon, who had already built a reputation in areas like nootropics, phospholipids, CoQ10, and L-carnitine. Brady arrived with a mandate to expand Designs for Health from a niche neuro-focused line into a full integrative functional medicine catalog.

Today the brand fields over 400 products and holds the position of one of the top recommended supplement brands among functional and integrative medicine providers in North America. The product line includes everything from targeted single-nutrient formulas to complex multi-ingredient blends designed around human clinical outcome data, not just preclinical animal models.

SuppCo anonymously purchased Designs for Health products through the same retail channels available to any consumer and submitted them to an ISO 17025-accredited independent laboratory for analysis. The lab tested for label accuracy, ingredient identity, and potency, verifying that what is on the label reflects what is actually in the bottle. The results confirmed that the products met their label claims within acceptable variance.

For a brand operating at 400-plus SKUs with formulations that include novel ingredients like geranylgeraniol and tocotrienol complexes, where dosing precision determines whether a product produces a clinical outcome or an expensive placebo, label accuracy is not a baseline expectation. It is the whole point.

I sat down with Dr. David Brady, Chief Medical Officer at Designs for Health, to dive deeper into the science.

JG: "How do you maintain the quality and scientific rigor that made the brand credible when you are now operating at 400-plus products?"

DB: "It is just being committed to excellence and only bringing in people who have that same commitment. I have been able to scour the functional and integrative medicine landscape and cherry-pick the best people, whether for our scientific advisory board or inside R&D. We never compromised on who we hired. A lot of our competitors have gone a whole different direction. They were bought two or three times over by private equity, brought public, brought back private. It becomes a very blue-sky, direct-to-consumer kind of business, and it is a whole different way of doing things. That is not our model. I would not still be here if it were."

JG: "Walk me through what quality control actually looks like at the ingredient level, before manufacturing even begins."

DB: "That is where it begins. We use a lot of graduate students from the University of Bridgeport to do deep literature reviews, and then it goes through our science team. We have a whole matrix we evaluate ingredients on. First, is it safe? Second, is it efficacious? And not just in animal studies, we are looking for human clinical outcome trials published in peer-reviewed journals. Then we get into vendor qualification, which our suppliers honestly hate because it is like an accreditation visit. There are a million questions and documents they have to supply. Sometimes the analytical method does not even exist yet for a novel ingredient, and we have to work out the methodology ourselves."

JG: "What does third-party testing mean to Designs for Health, and what drew you to the TESTED by SuppCo certification?"

DB: "Everyone says their products are the best quality. Everyone will say they do this, they do that. We actually do all this stuff. But it is not on the label, so how do you verify it? That is why something like SuppCo matters. A non-biased third party can evaluate what we send to validate our formulas, look at the science behind them, and then independently test the final product. It is totally outside our control, and then it gets rated. That is how you finally validate everything a brand does. And it adds real value because we are not a commodity price-point product. We are the best product. And now there is a way for someone to actually confirm that."

JG: "What do you wish clinicians and consumers understood about Designs for Health that never makes it onto the label?"

DB: "All the stuff that goes on behind the scenes that no one sees. We are sometimes 20 or 30 years ahead of the curve. Colostrum blew up a couple of years ago on social media like it was a new thing. We introduced colostrum into our line 23 years ago. We replaced synthetic folic acid with methylated folate before any other branded supplement company because I saw the proliferative data and the cancer study concerns emerging. We moved from alpha-tocopherol to delta and gamma tocotrienols for the same reasons. You can never put any of that on a label. There is just not enough space."

The Most Underrated Quality Signal: The Price You Pay at the Doctor's Office

I came into this conversation with the standard skepticism I apply to any brand making big claims about quality. Exercise physiology and nutritional biochemistry backgrounds do not make you trusting. They make you annoying at dinner parties and rigorous in interviews.

When a supplement company tells me it is science-first, I want to know what that means operationally. Anyone can print it on a website. But one thing Brady said stopped me, and it had nothing to do with ingredients or testing protocols.

Designs for Health deliberately prices their products so that buying through a qualified practitioner costs you less than buying direct or through an online marketplace. Not marginally less. Structurally, meaningfully less. The practitioner discount programs, the e-pharmacy infrastructure they build for providers, the rewards system, all of it is designed to make the clinical channel the rational economic choice for the consumer.

Think about what that signals. Most supplement brands, even serious ones, treat the direct-to-consumer channel as pure margin. Designs for Health inverted that. They are willing to accept less revenue per unit to ensure that more products end up in the hands of people who are being guided by someone qualified to recommend them. The practitioner is not just a distribution channel in their model. The practitioner is part of the product.

Brady has been in clinical practice for over 30 years himself. He told patients directly: buy through my dispensary, it costs you less, and it keeps this practice sustainable for both of us. That is an unusually honest conversation, and it only works if the pricing structure actually supports it.

You can still buy Designs for Health online. You can still go direct. But the system is built to reward doing it right. In an industry where the incentives almost always point the other direction, that is worth noting.
