Is Your Elderberry Real? Quality and Adulteration

In one round of testing, a supplement manufacturer analysed 25 bulk elderberry materials from suppliers. Fourteen failed the identity test. Five contained no elderberry at all.

Among eight finished elderberry supplements tested, two were also devoid of elderberry — one made mainly of a substance resembling oat bran, the other of vitamin C and excipients. Both were visually obvious once you knew what to look for: one white, one orange.

Elderberry has an adulteration problem, and it's better documented than almost any other botanical on the shelf. Here's what's actually going on and how to protect yourself.

Why Elderberry Specifically

Two things made elderberry a target.

Demand exploded. During the first months of the COVID-19 pandemic, elderberry sales rose sharply, and it became the top-selling dietary supplement ingredient in the mass-market channel and the third best-selling botanical in natural retail, according to the American Botanical Council's herb market reporting.

The economics are irresistible. Genuine elderberry extract can cost up to thirty times more than the most common substitute. When a supply chain can't meet a demand spike and a cheap lookalike exists, fraud follows.

Worth noting: this predates the pandemic. Reports of elderberry adulteration appear in the scientific literature from years earlier. COVID accelerated an existing problem rather than creating one.

What Elderberry Gets Faked With

The Botanical Adulterants Prevention Program — a consortium run by the American Botanical Council, the American Herbal Pharmacopoeia, and the National Center for Natural Products Research — published a peer-reviewed bulletin on elder berry adulteration in 2023, reviewed by twenty-two experts from academia, nonprofits, contract analytical laboratories, government agencies, and industry.

The adulterants it documents:

Black rice extract (Oryza sativa) — by far the most common. It's anthocyanin-rich, so it looks right and produces the deep purple colour buyers expect, at a fraction of the cost.

Other anthocyanin-rich plant extracts — purple carrot (Daucus carota), blueberry, and black chokeberry (Aronia melanocarpa) have all been detected.

Synthetic food colourants — including amaranth dye and Brilliant Blue FCF. This is the category that carries actual risk: undeclared food dyes are a different problem from a cheaper berry, and someone with a dye sensitivity has no way of knowing.

Species substitution — Sambucus williamsii, the North China red elder, reportedly increasing in the supply chain and not always declared on labels.

One honest note from the bulletin's authors: black rice extract, while it may not confer the same properties attributed to elder berry, does not pose the health risks that undeclared food dyes do. Not all adulteration is equally dangerous — but all of it means you didn't get what you paid for.

How Widespread Is It?

BAPP has reported that 11% of 532 elderberry products tested failed identity specifications.

The manufacturer testing described at the top of this article found a far higher failure rate in bulk material specifically — 14 of 25 failing identity, five containing no elderberry whatsoever.

Those numbers describe different things: one is a broad survey of finished products, the other a targeted look at bulk supply. Together they suggest the problem concentrates upstream, in raw material sourcing, before anything reaches a shelf.

How Laboratories Detect It

You can't do this at home, but knowing how it works explains why some formats are riskier than others.

Authentic elderberry has a characteristic anthocyanin fingerprint, and the key marker compounds are cyanidin-3-O-sambubioside and cyanidin-3-O-sambubioside-5-O-glucoside. Weak or absent signals for these are a red flag.

Conversely, certain compounds indicate something else is present. According to BAPP's director, the presence of peonidin-3-O-glucoside, peonidin-3-O-galactoside, and peonidin gives adulteration away — these have not been reported from elder berry.

Testing is done by high-performance thin-layer chromatography and high-performance liquid chromatography. It requires a lab, which is exactly why the problem persists.

The Format That Can't Be Faked

Here's the practical takeaway, and it's the reason this article exists.

Adulteration concentrates in extracts and powders. A purple powder or a liquid extract is a blank canvas — nothing about its appearance tells you what plant it came from. Black rice extract and elderberry extract look identical in a jar.

Whole dried berries are far harder to fake. You'd need actual berries of the right size, shape, and colour, and the economics stop making sense. There's no cheap substitute that physically resembles a dried elderberry.

This doesn't make powder untrustworthy — plenty of reputable powder is exactly what it says. It means the burden shifts entirely onto supplier verification, because you cannot check it yourself.

With whole berries, you can.

What to Look For in Whole Dried Berries

• Colour. Deep purple-black, almost inky. Brown-grey means degraded; unnaturally bright or uniform purple is worth questioning.
• Size and shape. Small, shrivelled, roughly spherical, with visible texture. Uniform to a suspicious degree suggests something processed.
• Stem fragments. A few are normal in any hand-processed material. Substantial green stem means careless processing — and stems carry more of the cyanogenic compounds than the fruit does.
• The brew test. Properly simmered elderberry produces a deep purple-black liquid with a distinct tart, dark-fruit flavour. If it brews pale or tastes of nothing, something is wrong.
• Species on the label. Sambucus nigra or Sambucus canadensis stated explicitly. A label that just says "elderberry" is telling you less than it could.

Questions Worth Asking a Supplier

• What species is it? Should be answerable immediately.
• Where is it grown? Region is reasonable; exact farms are often commercially confidential, but vagueness about the continent is not.
• Is it tested for identity, and how? HPTLC or HPLC anthocyanin profiling is the standard.
• For powder specifically: is the material heat-treated? Relevant to safety as well as authenticity.
• Is there certification? USDA Organic verifies the growing standard and chain of custody. It isn't an identity test, but a certified supply chain is a documented one.

A supplier who can't answer the first two isn't necessarily selling adulterated material — but they're demonstrating they don't know their own supply chain, which is where the problem starts.

The Farmer Soul Approach

Our elderberry is Sambucus nigra, carefully sourced from Eastern European botanical growers and USDA Organic certified.

We sell whole dried berries as the anchor product deliberately. Whole fruit is the format you can actually assess — colour, size, stem content, and how it brews. If our berries ever show up brown, dusty, or brewing pale, you'll know before we do, and we'd rather be held to a standard you can see than one you have to take on faith.

We also sell powder and syrup, and for those you're trusting our sourcing rather than your own eyes. That's true of every powder and syrup on the market, which is the honest thing to say about it.

Frequently Asked Questions

How common is elderberry adulteration?

BAPP has reported that 11% of 532 elderberry products tested failed identity specifications. Testing focused on bulk raw material has found substantially higher failure rates, including samples containing no elderberry at all.

What is elderberry usually adulterated with?

Most often undisclosed black rice extract, which is anthocyanin-rich and can cost up to thirty times less. Other reported adulterants include purple carrot, blueberry, black chokeberry, and synthetic colourants such as amaranth dye and Brilliant Blue FCF.

Is adulterated elderberry dangerous?

It depends what was used. BAPP's authors note black rice extract doesn't pose the health risks that undeclared food dyes do. Undeclared synthetic colourants are the more concerning category, particularly for anyone with a dye sensitivity.

Can I tell if my elderberry is real?

With whole dried berries, largely yes — check colour, size, stem content, and how it brews. With powder or extract, no. Definitive identification requires laboratory chromatography.

Why is elderberry targeted more than other herbs?

A demand spike during the pandemic collided with a large price gap between genuine extract and cheap anthocyanin-rich substitutes. Reports of adulteration existed before COVID; the surge amplified it.

Does USDA Organic certification prevent adulteration?

Not directly — it verifies growing practices and chain of custody rather than testing botanical identity. But a certified supply chain is a documented one, which makes undisclosed substitution considerably harder.

Are whole berries safer to buy than powder?

They're easier to verify. Adulteration concentrates in extracts and powders because appearance reveals nothing about species. Whole fruit is hard to counterfeit convincingly, which shifts the burden from trust to observation.
