Athlete Spotlight: John Cantrell Chooses LionBerry for Recovery & Focus

December 23, 2025

I met you at the Lennexa Christmas Market and purchased products from you. I am very much enjoying them and have seen great results. I’m a chemo patient (have been for 8 years) and this is something I think would help me on a regular basis.

"My daughter loves it so you did great on the flavoring! Thanks!"

"Hello, I bought some of your Lionberry brainiac tonic at the Home and Garden show in Overland Park. I love it so much and want to purchase more."

"We really believe your sips have been helpful to stay healthy this winter!"

"I have been sipping on it as you suggested and the taste is phenomenal."

METABOLIC RECOVERY

Lionberry 's Weekly Delusion and Re-illusion Update.

We've spent the last two years talking about GLP-1 drugs. No one is talking about what happens after.

The Metabolic Off-Ramp After GLP-1: Why the Post-Appetite Era Needs to Take a Food Systems Look at Elderberry

By 2030, an estimated 35% of American households — a staggering proportion for a single class of medications — will have someone on a GLP-1 receptor agonist.

This is no longer a niche population or a specialty intervention. It reflects a broad shift in how metabolic disease is being managed at scale in the United States, where rates of obesity and metabolic dysfunction remain among the highest in the world.

GLP-1 receptor agonists (including semaglutide and tirzepatide — marketed as Ozempic, Wegovy, Mounjaro, and Zepbound, with next-generation triple agonists such as retatrutide in development) are reshaping how the country thinks about weight, appetite, and metabolic health.

The pharmaceutical conversation is settled. These drugs work — and they work well.

It is a structural intervention in the biology of a nation—a direct shift in how the United States addresses its metabolic problem. What happens next?

What happens after appetite suppression?

GLP-1 medications cost roughly $1,000 a month. They require weekly injections.

And the clinical data on discontinuation tells a consistent story: when patients stop, the weight returns. The weight loss (metabolic gains) do not hold without ongoing support — and for some patients, that reality is deeply frustrating.

This is not a distant or theoretical concern. This is a question millions of Americans are about to have to ask.

If these drugs change the trajectory of weight and metabolism, what supports that trajectory once the prescription ends — or for those who never start?

That is the opening for a new food conversation around metabolic recovery.

A 2024 clinical trial out of Washington State University suggests there may be more to the food side of that question than previously assumed.

The Initial Study

Researchers at WSU's Elson S. Floyd College of Medicine, led by Patrick Solverson, assistant professor of Nutrition and Exercise Physiology, published the results of a randomized, placebo-controlled crossover trial in the journal Nutrients [1].

It is exciting research — both because the question is timely and because the team chose to study a food-based metabolic pathway with unusual precision.

The initial study was funded by a $200,000 grant from the United States Department of Agriculture's National Institute of Food and Agriculture [2].

The trial tested elderberry juice against a flavor- and sugar-matched placebo in 18 overweight adults over one week.

The results were more than notable.

Postprandial blood glucose — blood glucose after eating — decreased by 24%.

Fat oxidation increased 27% both at rest and during exercise, meaning the body was burning more fat for fuel.

Insulin levels trended lower by 9%, though this result did not reach statistical significance in the small cohort — the direction is consistent with the glucose and fat oxidation outcomes and warrants attention in future, larger trials.

Beneficial gut bacteria increased while harmful species declined, including increases in Bifidobacterium, a bacterial population that expands as a result of anthocyanin fermentation in the gut and contributes to the generation of short-chain fatty acids involved in signaling L-cells to release GLP-1.

The microbiome shifted toward a profile associated with improved metabolic health — in seven days [1].

For a one-week food intervention, those findings are striking. They suggest that elderberry may have relevance not only to blood sugar regulation, but to the broader question of metabolic recovery in the GLP-1 era — particularly for people who have discontinued these medications and need their biology to hold its ground.

The Mechanism

What makes the WSU findings particularly relevant to the GLP-1 conversation is not just the outcomes but the biological pathway they appear to engage.

Elderberry is exceptionally dense in cyanidin-based anthocyanins — bioactive pigment compounds that function as prebiotic fuel in the gut.

When these anthocyanins reach the lower digestive tract, they are metabolized by gut microbes into bioactive compounds that support the growth of bacteria such as Bifidobacterium, which in turn drive the production of short-chain fatty acids (SCFAs) [1].

Those SCFAs — butyrate, propionate, and acetate — reduce inflammation in adipose tissue (body fat), which is a metabolically active tissue that can become chronically inflamed and contribute to insulin resistance.

By reducing this inflammation, SCFAs help improve insulin sensitivity and metabolic function, and they directly stimulate L-cells in the intestinal lining to secrete GLP-1 [3]. The same hormone that semaglutide was engineered to mimic.

The distinction is important. This is not a supplement making a structure-function claim. This is a food-based mechanism, documented in peer-reviewed literature, that supports the body's endogenous GLP-1 production through the gut microbiome.

The functional interaction between gut microbiota and host metabolism is well established in the literature [4].

This is part of why elderberry may matter as more than an immune-support ingredient: it may have a role in food-based metabolic recovery.

Something a person can incorporate daily — during or after a GLP-1 prescription — to support the pathway the drug was engaging.

The Processing Gap

Not all elderberry products are created equal.

The WSU results used elderberry juice. The active compounds — the anthocyanins driving the metabolic effects — are heat-sensitive.

Research on the thermal degradation kinetics of elderberry polyphenolic compounds has shown that heating at temperatures ranging from 212 to 302°F (100 to 150°C) causes significant structural changes in anthocyanins, degrading both the bioactive compounds and their antioxidant activity [5].

At 203°F (95°C), only 50% of elderberry pigments remained after three hours of heating [6].

Elderberry in particular, with its softer peel structure, has been shown to be more prone to anthocyanin degradation by heat than other berry fruits [7].

Most commercial elderberry products sold on grocery store and drugstore shelves — syrups, gummies, capsules — undergo extended high-heat processing from large-scale factory production. This is standard for food safety, cost efficiency, and volume, but it degrades a significant portion of the elderberry anthocyanins responsible for the prebiotic and metabolic recovery observed in the trial.

The Off-Ramp Opportunity

WSU is continuing this line of research. With an additional $600,000 in NIFA funding, Solverson's team is now investigating whether elderberry can help patients maintain weight loss and metabolic stability after discontinuing GLP-1 medications [2].

These are the clinical results — and the follow-on research questions — that matter.

Three consumer segments are emerging in the GLP-1 era, all underserved:

Patients transitioning off GLP-1 drugs who need metabolic recovery to sustain their results.

Consumers who prefer a food-based approach and do not intend to start pharmaceutical intervention.

A broader population seeking daily metabolic recovery through diet rather than supplementation.

Elderberry, with a documented mechanism running through the gut microbiome to endogenous GLP-1 production, is the candidate worthy of serious attention.

Where Berberine Fits — and Where It Does Not

Berberine has earned its position in the metabolic health conversation. It is an isoquinoline alkaloid derived from plants including goldenseal (Hydrastis canadensis) and Oregon grape.

Its primary mechanism of action is activation of adenosine monophosphate-activated protein kinase (AMPK), a key regulator of cellular energy metabolism.

In animal models of insulin resistance, berberine has been shown to reduce body weight, improve glucose tolerance, lower plasma triglycerides, and improve insulin action [8]. Its effects on blood glucose are real.

However, berberine is a concentrated plant extract delivered in capsule form. The efficacious dose is not achievable through dietary intake, and its oral bioavailability is less than 1% [9].

It does not function as a prebiotic. It does not stimulate GLP-1 through the SCFA pathway. It operates outside the food system.

The framing of berberine as "nature's Ozempic" was effective marketing, but it may have narrowed the conversation prematurely.

The more productive question is not which botanical extract mimics a pharmaceutical. It is which whole food or minimally processed ingredient supports the biological pathway the pharmaceutical was designed to target — through the gut, through the microbiome, through something a person can drink.

The Larger Picture

Elderberry is a great part of the answer. A USDA-funded clinical trial with statistically significant metabolic outcomes, a documented GLP-1 mechanism, and an active follow-on study on post-drug maintenance suggests it deserves a place in the conversation.

The research is there. The mechanism is specific. The consumer need is growing by the month.

For the millions of Americans who will step off a GLP-1 drug and need somewhere to land, elderberry may be the metabolic recovery off-ramp they have been waiting for.
