What Are Glandular Supplements?
Glandulars are supplements made from freeze-dried organs and glands of animals—typically bovine (cow) or porcine (pig) sources. The idea behind glandular therapy is the concept of “like supports like,” a principle found in both Traditional Chinese Veterinary Medicine and early Western naturopathic approaches.
In simple terms: feeding liver supports liver health, feeding adrenal glands supports adrenal function, and so on.
How Glandulars Work
These supplements provide:
Organ-specific peptides and enzymes to nourish and support the corresponding organ in your dog
Naturally occurring vitamins, minerals, and cofactors found in the tissues
Bioavailable nutrients that are more easily absorbed than synthetic versions
Energetic support aligned with TCVM principles (e.g., warming/cooling properties)
They may be especially helpful when a dog has a deficiency, organ stress, or genetic weakness in a specific system.
Common Glandulars and Their Uses
Liver Glandular
Supports detoxification, bile production, digestion, and recovery from medications or liver damage.
Often used in dogs with elevated liver enzymes, toxin exposure, or chronic inflammation.Kidney Glandular
Helps support renal tissue, hydration balance, and electrolyte regulation.
Beneficial in aging dogs or those with early kidney stress (e.g., before bloodwork shows pathology).Pancreas Glandular
Used for dogs with pancreatic insufficiency or poor digestion.
Often combined with digestive enzymes.Adrenal Glandular
Supports dogs under chronic stress, with suspected adrenal dysfunction (Cushing’s or Addison’s tendencies), or those needing help regulating cortisol.Thyroid Glandular
Supports metabolism and thyroid health, though it should never be used without thyroid testing due to the risk of over-supplementation.Heart Glandular
May benefit dogs with cardiovascular concerns or breeds prone to Dilated Cardiomyopathy (DCM).
Contains naturally occurring CoQ10, taurine, and other heart-supportive compounds.Brain Glandular
Helps support cognitive function in senior dogs and may aid puppies with developmental issues.
Sometimes used in seizure dogs for neuro-nourishment.Spleen, Thymus, and Lymph Glandulars
Immune-modulating; help support lymphatic detox, red and white blood cell production, and general immune defense.
When to Use Glandulars
Consider glandular support when:
Your dog has a known organ-related condition
You want to prevent degeneration in a genetically vulnerable breed (e.g., kidney support in senior Shih Tzus)
Bloodwork or symptoms suggest functional stress (e.g., fatigue, poor digestion, muscle loss)
You're feeding a homemade diet that may lack specific organ variety
You're supporting a detox, recovery, or regeneration protocol
How to Choose a Glandular Supplement
Choose a single-source or blend based on your dog’s needs (e.g., just liver vs. a full multi-gland formula).
Prefer grass-fed, hormone-free sources.
Look for freeze-dried or desiccated (not heat-treated) to preserve nutrients.
Avoid added synthetic vitamins, fillers, or artificial flavors.
Choose bovine over porcine if your dog has pork sensitivity.

Do Glandulars Replace Organs in the Diet?
Not entirely — but can be helpful if:
Your dog won’t eat raw organs or your don’t have access to organs (RAW diets)
You're feeding cooked meals (which may degrade organ nutrients)
You’re targeting a specific health issue
You’re rotating through various support supplements seasonally
