If you’re formulating supplements for the growing ancestral health market, you’ve probably noticed something interesting. While bovine organ powders like liver and heart have been gaining traction for years, there’s another category that’s quietly exploding in popularity: bovine glandulars. These specialized powders target specific endocrine and immune functions in ways that traditional organ supplements simply can’t match. But what exactly are glandulars, and how do they differ from the organ powders your customers already know and love?
For supplement brands, formulators, and private label companies looking to expand their product lines, understanding bovine glandulars isn’t just helpful. It’s essential. The demand for targeted, whole-food-based endocrine support is growing faster than most people realize, and the brands that get ahead of this trend now will be the ones capturing market share in the coming years. At Gembra Health, we’ve been supplying premium New Zealand bovine glandulars to professional supplement manufacturers for years, and we’ve seen firsthand how these products are reshaping the nutraceutical landscape.
What Are Bovine Glandulars?
Bovine glandulars are freeze-dried powders made from the glands of grass-fed cattle. Unlike organ powders, which come from metabolic organs like the liver or kidneys, glandulars are derived from endocrine glands that produce hormones and regulate specific bodily functions. Think thyroid, adrenal, pancreas, thymus, and pituitary glands. These tissues contain unique peptides, enzymes, and cofactors that support the corresponding glands in the human body.
The concept behind glandular therapy isn’t new. It’s actually rooted in a principle that goes back centuries: “like supports like.” The idea is that consuming tissue from a specific gland provides targeted nutritional support for that same gland in your own body. While the mechanisms aren’t fully understood by modern science, glandular supplements have been used in clinical practice for decades, particularly by functional medicine practitioners and naturopaths. What’s changed recently is the quality and sourcing of these products, along with consumer awareness of their benefits.
We source our bovine glandulars exclusively from New Zealand, where cattle are raised on pristine pastures without hormones, antibiotics, or GMO feed. This isn’t just a marketing point. New Zealand’s strict agricultural standards and disease-free status make it the gold standard for glandular sourcing. When you’re dealing with endocrine tissue, purity matters more than ever. Hormone-disrupting chemicals, environmental toxins, and pharmaceutical residues can all accumulate in glandular tissue, which is why sourcing from the cleanest possible environment is non-negotiable.
How Glandulars Differ From Organ Powders
Here’s where things get interesting. While both glandulars and organ powders come from bovine sources and undergo freeze-drying, they serve fundamentally different nutritional purposes. Organ powders like liver, heart, and kidney are metabolic powerhouses. They’re packed with vitamins, minerals, and cofactors that support general health and energy production. Liver, for example, is loaded with vitamin A, B vitamins, iron, and copper. It’s essentially a whole-food multivitamin in powder form.
Glandulars, on the other hand, are specialists. They contain tissue-specific compounds that don’t appear in significant amounts elsewhere. Bovine thyroid powder, for instance, contains naturally occurring thyroid hormones and the building blocks your body needs to produce its own thyroid hormones. Bovine thymus provides peptides that support immune function and T-cell production. Bovine pancreas delivers enzymes that aid in digestion and blood sugar regulation. You won’t find these same compounds in liver or heart powder, no matter how high the quality.
This distinction matters when you’re formulating products. If your customers are looking for broad-spectrum nutritional support, organ powders are the way to go. But if they’re dealing with specific endocrine or immune challenges, glandulars offer targeted support that organs simply can’t provide. Many of our clients actually combine both categories in their formulations, creating comprehensive products that address multiple systems at once. It’s not an either-or proposition. It’s about understanding which tissues provide which benefits and formulating accordingly.
The Glandulars We Supply and Why They Matter
Let’s break down the specific glandular products we offer at Gembra Health and what makes each one valuable for your formulations. These aren’t obscure ingredients anymore. They’re becoming staples in high-end supplement lines, and for good reason.
Bovine thyroid is probably the most well-known glandular supplement, and it’s one of our top sellers. The thyroid gland regulates metabolism, energy production, body temperature, and hormonal balance throughout the entire body. When thyroid function is suboptimal, everything suffers. Our bovine thyroid powder provides a natural source of thyroid hormones along with the nutrients needed for healthy thyroid function. It’s particularly popular among functional medicine practitioners who work with clients dealing with sluggish metabolism or low energy. For supplement brands, thyroid support products represent a massive and growing market segment, especially among women over 35 who make up the largest demographic seeking thyroid support.
Bovine pancreas is another glandular that’s seeing increased demand, particularly in digestive health formulations. The pancreas produces enzymes that break down fats, proteins, and carbohydrates, making proper digestion possible. Our bovine pancreas powder contains naturally occurring digestive enzymes along with tissue-specific factors that support pancreatic health. It’s commonly used in enzyme supplements, but it’s also finding its way into metabolic support formulas targeting blood sugar regulation. The pancreas doesn’t just handle digestion. It also produces insulin and glucagon, the hormones that control blood sugar. That dual function makes pancreatic support relevant for a much broader audience than most people realize.
Bovine thymus is fascinating because it bridges endocrine support and immune function. The thymus gland is where T-cells mature, which makes it central to adaptive immunity. Our bovine thymus powder provides peptides and growth factors that support thymus health and, by extension, immune resilience. It’s particularly valuable for older adults, since thymus function naturally declines with age. But we’re also seeing increased interest from brands formulating immune support products for younger demographics who want proactive, whole-food-based immune support rather than isolated vitamins. Thymus also supports skin health, connective tissue, and even cardiovascular function, which gives it broader appeal beyond just immunity.
We also supply bovine prostate and bovine testes (orchidic) for men’s health formulations. These glandulars are gaining serious traction in the men’s wellness space, particularly among younger men interested in natural testosterone support and reproductive health. Bovine prostate supports prostate health, healthy urine flow, and urinary tract function. It’s commonly used by men over 40 as a preventative measure. Bovine testes provides nutrients that support male hormone production and fertility. The men’s health supplement market is exploding right now, and glandular-based formulas are capturing a significant share of that growth.
Finally, we offer ovine thymus alongside our bovine products. Some formulators prefer ovine (sheep) glandulars because sheep are even less likely to carry disease than cattle, and they graze on some of the most remote, pristine pastures in New Zealand. Functionally, ovine thymus provides the same immune and connective tissue support as bovine thymus, but some practitioners and brands prefer ovine sourcing for philosophical or marketing reasons. We provide both options so you can formulate according to your brand values and customer preferences.
Why New Zealand Sourcing Makes All the Difference
When you’re sourcing glandulars, origin matters more than almost anything else. Glandular tissue can concentrate environmental toxins, heavy metals, and pharmaceutical residues if the source animals are raised in industrial farming systems. New Zealand eliminates those concerns almost entirely. The country has some of the strictest agricultural regulations in the world, and it’s remained free from many of the diseases that affect cattle populations elsewhere. BSE (mad cow disease), foot-and-mouth disease, and other livestock illnesses that have plagued other regions are virtually nonexistent in New Zealand.
Beyond disease-free status, New Zealand cattle are raised on pasture year-round. They’re grass-fed and grass-finished, meaning they never receive grain-based feed or spend time in feedlots. This isn’t just about omega-3 content or nutrient density, although those benefits are real. It’s about avoiding the contamination that comes from industrial feed operations, including mycotoxins, pesticide residues, and GMO exposure. When you’re producing glandular supplements that people will take specifically to support their endocrine health, you can’t afford to introduce new problems while trying to solve existing ones.
Our freeze-drying process preserves the delicate peptides and enzymes found in glandular tissue without denaturing them through heat. We also keep our glandular powders non-defatted, which means they retain their natural fat content. This is critical because many of the bioactive compounds in glandular tissue are fat-soluble. Removing the fat to create a “leaner” powder might sound appealing from a marketing standpoint, but it actually reduces the nutritional value of the end product. We prioritize function over aesthetics, and that’s one of the reasons professional formulators keep coming back to us.
Formulating With Glandulars: What You Need to Know
If you’re considering adding glandulars to your product line, there are a few practical considerations worth discussing. First, dosing matters. Glandular supplements typically require higher doses than vitamin-based products to deliver noticeable benefits. Most clinical protocols use between 500mg and 2,000mg per day depending on the specific glandular and the intended outcome. That means you’ll need to account for capsule size, serving recommendations, and cost per serving when you’re developing your formulas.
Second, glandulars work best as part of comprehensive formulations. Combining bovine thyroid with selenium, iodine, and zinc creates a more effective thyroid support product than thyroid alone. Pairing bovine pancreas with digestive enzymes and bile salts delivers better results for digestive health. The glandular provides tissue-specific support, while the cofactors ensure the body has everything it needs to utilize that support effectively. We work with many formulators who use our glandulars as foundational ingredients and then build around them with complementary nutrients.
Third, sourcing transparency is becoming increasingly important to consumers. The supplement industry has been burned too many times by low-quality imports and undisclosed sourcing practices. Your customers want to know where their glandulars come from, how they’re processed, and what quality controls are in place. Working with a supplier that can provide complete traceability from pasture to powder isn’t just a nice-to-have anymore. It’s a competitive advantage. We maintain full documentation on our sourcing and processing, and we’re happy to provide that information to brands that want to share their sourcing story with their customers.
Building Your Brand Around Glandular Supplements
The ancestral health movement has created a unique opportunity for supplement brands willing to go deeper than surface-level wellness trends. Consumers in this space aren’t looking for the cheapest option or the most convenient packaging. They’re looking for products that actually work, backed by real ingredients from trustworthy sources. Glandular supplements fit perfectly into this market because they represent a return to traditional nutrition practices that have been largely forgotten in modern diets.
Nobody eats organ meats anymore, let alone glandular tissue. But our ancestors consumed these parts of the animal regularly, and they reaped the nutritional benefits that came with it. Glandular supplements allow people to access those same benefits without having to source, prepare, and consume actual glands. It’s ancestral nutrition made practical for modern life, and that’s a message that resonates powerfully with health-conscious consumers who are tired of synthetic vitamins and isolated compounds that don’t reflect how nutrition actually works in nature.
