What Produce Buyers at CFIC Were Asking About Muscadines — and Why It Matters to Formulators

Wray, Georgia, evening light over the lake. Some weeks get away from you. The vine keeps growing regardless.

If you’re sourcing a polyphenol ingredient and looking for one with a consumer story already taking shape, this week’s post is worth reading before you make that decision.

We were in Myrtle Beach last week for the Carolina Food Industry Conference. My dad, Gary, and I attended as Crystal Sponsors, and most of our conversations focused on the produce and wine tracks — discussing fresh muscadines, flavor, regional identity, and what the category looks like heading into harvest.

One thread kept coming up in those conversations that I want to revisit in this series: consumer interest in muscadines.

Produce buyers are practical people. They stock what moves. What they told us, more than once, is that consumer curiosity about the health benefits of fresh muscadines is growing. Not in a clinical-trial kind of way — in a ‘my customer is asking questions, and I want to be able to answer them’ kind of way. They wanted to know what makes muscadines different from conventional grapes, what the science behind them looks like, and how to communicate that to customers.

For a formulator following this series, that conversation matters more than it appears.

Why Consumer Produce Interest Creates Formulator Opportunity

When produce buyers start asking about health benefits, it’s usually a sign that consumer awareness is ahead of the retail category. People are already researching muscadines, reading about polyphenols, and asking questions at the store level. That awareness doesn’t stay in the produce aisle.

Consumers who discover muscadines as a health food — through the fresh market, regional media, or word of mouth in the Southeast — become consumers who look for muscadine on supplement labels. The fresh market and the supplement market aren’t separate conversations. They’re the same consumer at different points in their journey with the fruit.

For a formulator building in polyphenol categories — antioxidants, cardiovascular, metabolic, and gut health — growing consumer name recognition for muscadine is a brand asset, not just a farming metric. It means your label can say ‘muscadine’ and more consumers will know what it means than did five years ago.

What Makes Muscadine Different — The Version We Shared at CFIC

The conversation with produce buyers wasn’t technical. It was about flavor, story, and place. Muscadines (Vitis rotundifolia) are native to the American Southeast — a distinct species from the conventional wine grape (Vitis vinifera) most people think of when they hear ‘grape.’ Their flavor is fuller and more complex. Their skin is thicker. Their seeds are larger. And their phytochemical profile — ellagic acid, OPCs, anthocyanins, resveratrol — is meaningfully different from that of vinifera-derived ingredients.

That distinctiveness is exactly what produce buyers want to communicate to their customers. It’s also exactly what formulators can build on when they source muscadine as an ingredient — a documented phytochemical profile from a distinct botanical species with a regional identity that most polyphenol ingredients can’t match.

Paulk Vineyards grows more than 800 acres of muscadines in Wray, Georgia — seventh generation on the farm, fourth with muscadines. The fruit that goes into MPC’s ingredient forms is the same fruit that produce buyers increasingly put in the fresh case. One estate. One supply chain. One story.

What This Means for Your Formula Right Now

If you’re building a supplement that features muscadine as a named ingredient, consumer awareness is working in your favor in a way it wasn’t a decade ago. The regional identity is established in the Southeast, and consumer interest is expanding beyond that region. The conversation about consumer interest is already happening at the retail level. And the phytochemical profile gives your R&D team a documented starting point for the formulation conversation.

We’ll be back to the cardiovascular research series next week — the post on the polyphenol and vascular function landscape that was scheduled before the conference. The fresh market signal we heard in Myrtle Beach is real, and it connects directly to the ingredient opportunity we’re building this series around.

Why What We Grow Matters for Your Heart

Hands holding Noble muscadines.

I missed last week’s post. I was in Myrtle Beach for the Carolina Food Industry Council’s annual convention — meeting with grocery buyers to discuss our wine and fresh muscadines. I’ll come back to that in a moment, because something that came up in those conversations connects directly to what we’re discussing this month.

Most people who take a daily supplement have never considered where the ingredients actually come from.

Which farm. Which region. Which plant variety. How it was grown, processed, and turned into the thing in the bottle. That information rarely makes it onto a label — and most brands don’t volunteer it because they don’t know it themselves. They bought the ingredient from a supplier who bought it from a broker who sourced it from somewhere overseas, and the trail goes cold fast.

That’s not a knock on the industry. It’s just how most of it works. But it does matter — especially when the research behind a product was conducted on a specific variety from a specific source, and the product you’re buying may or may not reflect that.

Where Purple Power Actually Comes From

If you’ve ever looked at a supplement label and wondered whether what’s in the bottle aligns with the research behind it — that’s a fair question. Here’s the answer for ours.

Our Noble muscadines are grown at Paulk Vineyards in Irwin County, Georgia. My father, Gary, and my son, Seth, work this land alongside our farm crews. We’ve grown the Noble variety here for four generations — Jacob Paulk Sr. planted the first vines around 1970, and Seth is the fourth generation to tend them.

After harvest, we process the fruit ourselves. Purple Power is made from the Noble muscadine skins — dried and concentrated into a powder you can blend into a smoothie or mix with water each morning. From the vine to the canister, every step happens here. We know the soil. We know the variety. We know what goes in.

Traceability isn’t a marketing point. It’s what makes the research relevant. When published studies examine the Noble muscadine specifically, those findings speak directly to our fruit — grown from the same variety, on the same land, and processed the same way.

Anthocyanins
The Dark Side
Found in the Noble Muscadine grape skin		The dark color of the Noble muscadine skin is where these natural plant pigments live — and where Purple Power starts. These are the same natural plant compounds that researchers have examined for cardiovascular support, grown on our farm and processed by our team.

What the Grocery Buyers Were Asking About

Back to Myrtle Beach. The produce buyers we met at the CFIC convention were interested in many things — shelf placement, pricing, logistics. But what kept coming up, especially among the health-focused buyers, was the health benefits of fresh muscadines. Not just as a fruit, but as a functional food.

That’s a shift. For most of the history of fresh muscadine sales, the conversation has focused on flavor and seasonality. Now buyers want to know what the fruit actually does. That’s the market catching up to what research has been saying for years — and it’s a signal worth paying attention to.

The same fruit those buyers are asking about is what’s in Purple Power. We grow it fresh for the produce market. We process it into something you can take every morning. Same vine. Same farm. Same family.

You can’t tend what you don’t know. Knowing where your supplement comes from is the first step.

Why It Matters for Your Daily Habit

When you take Purple Power, you’re not hoping the ingredient matches the research. You’re taking the same part of the Noble muscadine that cardiovascular research has examined — grown on the same land by the same family and processed fresh from our farm.

The cost of not knowing is paying for something that may have nothing to do with the research you read. That’s a real risk with most supplements. It doesn’t have to be with this one.

One canister. Every morning. You know exactly where it came from.

Your Heart Works Every Single Day. Are You?

Purple Power cannister on a table

Your heart beats roughly 100,000 times a day. It doesn’t take weekends off. It doesn’t skip a beat because you got busy, forgot, or decided to start Monday.

Most of us know heart health matters. We’ve heard it from doctors, read it in articles, or maybe had a conversation that made us uncomfortable and then moved on. The problem isn’t awareness. It’s that heart health feels abstract until it isn’t — and by then, the conversation is harder.

July’s theme is Built to Last. Four weeks on cardiovascular health — what supports it, what the research shows, and what one daily habit actually looks like. This week is the foundation.

I get it — heart health is easy to push to later. Here’s what I know moves the needle.

Why the Heart Responds to Daily Habits

Cardiovascular health isn’t built in dramatic moments. It’s built in the ordinary ones — what you eat for breakfast, whether you move your body, how you manage stress, and what you give your heart to work with every day.

Research on natural plant compounds and cardiovascular support is among the most studied areas in functional nutrition. Natural plant compounds found in deeply colored fruits — including polyphenols — have been examined across multiple published trials for their potential to support healthy cardiovascular function. The Noble muscadine is one of the more concentrated natural sources of these compounds.

A clinical study by Mellen et al. specifically examined muscadine grape supplementation and cardiovascular markers in a study population and found meaningful results. That research was conducted on muscadine specifically — not a generic fruit extract — which matters when you’re deciding what to put in your body every morning.

Anthocyanins The Dark Side Found in the Noble grape skinThe deep color of the Noble muscadine isn’t just how it looks — it’s what’s packed inside the skin. These natural pigments are among the more studied plant compounds in cardiovascular research, and the Noble grape is a notable natural source of them.

Why Purple Power

Purple Power is our whole Noble muscadine skin powder — the entire fruit skin, concentrated into a form you can add to a smoothie, mix into water, or blend however works best for your morning.

We introduced it in the context of my morning smoothie a few weeks ago. The reason it’s the anchor product for July is straightforward: the skin of the Noble muscadine is where anthocyanins are highly concentrated — the same compounds that consistently appear in cardiovascular polyphenol research. If heart health is the goal for this month, the skin is the most relevant part of the fruit to put to work daily.

Four generations of our family have grown this vine in Irwin County, Georgia. We process it ourselves. Purple Power is what the Noble muscadine skin becomes when we do our job right.

Built to last doesn’t mean built in a day. It means tended faithfully, one morning at a time.

Start Before You Have To

The people who tend their cardiovascular health proactively don’t usually end up in the conversations that make everyone uncomfortable. That’s not a guarantee — nothing in health is — but the odds shift when you’re building something rather than waiting to catch up.

This month, we’ll cover the research, the sourcing story, a midyear check-in, and a personal close. But it all starts here: one daily habit, built around the whole Noble muscadine skin, taken consistently because your heart keeps working whether you are or not.

A heart that’s been tended faithfully keeps showing up for everything you want to do. That’s the goal. That’s what Built to Last means.

Muscadine and Cardiovascular Health: What the Research Shows and Why It Matters for Your Formula

Wray, Georgia, evening light over the lake. Some weeks get away from you. The vine keeps growing regardless.

If you’re developing a cardiovascular supplement, you already know the challenge: the category is competitive, consumers are sophisticated, and retailers and practitioners have seen enough weak science to ask tough questions. You need an ingredient with a solid research story behind it — not a mechanistic rationale dressed up as clinical evidence.

Muscadine is that ingredient. It has a documented phytochemical profile featuring compounds that appear throughout the polyphenol-vascular research literature, a peer-reviewed human trial specifically on muscadine grape seed and cardiovascular markers, and a fully traceable domestic estate supply chain. That’s a combination most cardiovascular botanical ingredients on the market can’t match.

Here’s what that research shows — and how to use it honestly in your formula.

The Problem Formulators Bring to Us

The formulators who come to us are looking for a cardiovascular ingredient that does three things: connects to published research, has a traceable supply chain, and gives their brand a story that holds up when a buyer or practitioner asks the right questions.

Muscadine addresses all three. The phytochemical profile is documented. A human trial exists, and we’ll tell you exactly what it found. Paulk Vineyards grows muscadines on 800+ acres in Wray, Georgia — seventh generation on the farm, fourth with muscadines — with MPC processing everything on-site. One supply chain. No brokers.

That gap is where brands get caught — in a retailer’s science review, a practitioner’s due diligence, or a direct question from a consumer who reads labels. The brands that hold up in this category long term are those that built on honest research foundations from the start.

The Research Context Muscadine Brings to the Table

Muscadine’s phytochemical profile — anthocyanins, OPCs, ellagic acid, and resveratrol — places it squarely within the class of compounds most extensively studied for vascular health. A 2022 systematic review published in Nutrients (Grosso et al.) examined human studies on dietary polyphenol consumption and its associations with vascular health, blood pressure, and hypertension.

The review found that some polyphenol-rich food categories — particularly those rich in anthocyanins — show evidence of an association with blood pressure outcomes, and that anthocyanin intake was consistently associated with reduced hypertension risk across prospective cohort data — an epidemiological finding, not a clinical claim about any specific supplement product.* The proposed mechanisms include nitric oxide bioavailability, support for endothelial function, and antioxidant activity in vascular tissue.

Muscadine contains all of those compound classes. The review examined dietary polyphenols broadly, not muscadine specifically — and that distinction matters for how you use this research in a label-claim context. But it establishes a meaningful scientific framework for why muscadine’s profile warrants a formulator’s attention in this category.

(See the full disclaimer at the end of this post regarding the scope of these findings.) The distinction matters. A formulator should not cite this review as clinical evidence that a muscadine supplement supports cardiovascular health. It provides a research framework — both mechanistic and epidemiological — showing that the class of compounds found in muscadine has been studied in relation to vascular health. That’s a legitimate research context. It is not a finished clinical claim.

The Muscadine Human Trial: Honest, Peer-Reviewed, and Worth Knowing

The Mellen et al. study (Journal of the American College of Nutrition, 2010) is the most directly relevant published human trial on muscadine and cardiovascular markers. It’s a randomized, double-blind, placebo-controlled crossover trial — one of the most rigorous study designs in nutritional science. The trial included 50 adults with coronary disease or at least one cardiac risk factor. Muscadine grape seed supplementation was 1,300 mg daily for four weeks.

We’re going deeper into that study next week: the full methodology, what the secondary finding does and doesn’t mean, and how a formulator should approach positioning an ingredient whose best clinical trial produced a null primary result.

What Muscadine Gives a Cardiovascular Formulator

We understand the commercial pull of this category — cardiovascular is one of the largest supplement markets, and consumers are actively seeking products. The challenge is building something you can stand behind when the questions get hard. An honest cardiovascular formula story looks like this:

  • A phytochemical profile — anthocyanins, OPCs, ellagic acid, and resveratrol — with documented presence in the polyphenol-vascular research literature
  • A peer-reviewed, randomized, placebo-controlled human trial focused specifically on muscadine grape seed — with outcomes accurately disclosed, including the null primary endpoint
  • A fully traceable domestic estate supply chain: Paulk Vineyards grows, MPC processes, no brokers, and full lot documentation
  • An ingredient partner who will provide you with the research, the documentation, and an honest account of what it shows — so your regulatory team can build claims that hold up

Aging Well Is a Choice You Make Every Day

Hands holding Noble muscadines.

Nobody drifts into aging well.

That’s the part the health industry doesn’t always say out loud. There’s a lot of talk about products and protocols, but not enough honest conversation about what’s behind the people who seem to age better than others. It’s not luck. It’s not genetics alone. It’s a series of small decisions, made consistently, over a long time.

Most of us know this. It’s just easier to think about it later.

The problem with later is that it becomes faster than you expect. And by then, you’re not building something — you’re playing catch-up on what you didn’t tend to.

Ellagitannins: The Seed’s Secret Found in the Noble grape seedMost of what makes our Seed Capsule worth taking is hiding inside the Noble grape seed itself — a natural compound your body converts and puts to work supporting overall cellular health. It’s what’s inside the inside.

What Tending Actually Looks Like

This month we’ve covered free radicals, antioxidant defense, the specific research behind the Noble muscadine, and why summer is a high-demand season for your body. This week I want to pull it all together into something simpler.

Aging well isn’t a dramatic intervention. It’s not a cleanse or a transformation program. It’s the accumulation of faithful daily inputs — sleep, movement, real food, stress managed as much as possible, and supplementation that does something.

The Noble muscadine seed contains natural plant compounds that research suggests may support overall cellular health over time. That’s not a flashy claim. It’s a quiet one. But quiet is what compounding looks like before it becomes visible.

My family has grown this vine for four generations on the same land in Irwin County, Georgia. What I’ve seen across those generations is that the things worth having — the soil, the vine, the health of the people who tend them — all respond the same way to the same input: consistent care, over time, without drama.

The vine doesn’t produce because it tries harder in one season. It produces because it was tended faithfully in all of them.

The Cost of Not Deciding

Here’s the thing about aging: it happens whether you’re intentional about it or not. The question isn’t whether time passes. It’s whether you show up for it.

People who drift through their forties and fifties without tending to the basics don’t usually notice until the gap becomes obvious — in energy, in resilience, and in how they feel getting out of bed. By then, the work is harder. Not impossible. Just harder.

One capsule every morning isn’t a magic solution. It’s a decision. A small one. But small decisions made daily are the only ones that actually change anything over time.

The Choice

Our Muscadine Seed Capsules are the simplest way to add the Noble muscadine’s natural plant compounds to your daily routine. Grown on our farm. Pressed by us. Four generations of tending this vine so you can take one capsule and know exactly where it came from.

That’s the close of June’s series. Not a dramatic finish — just an honest one. Aging well is a choice you make today, tomorrow, and the day after.

The people who make that choice consistently are the ones who feel capable and present at 60, 70, and beyond — not by luck but by faithfulness.
