We address the cause — not just the symptom.
Every Barklyn formula follows the same principle: evidence-based actives, honestly dosed — for gut & immune health, the nervous system, joints, coat, or as a plant-based repellent. Choose your product below, or take a closer look at how our bestseller works.

Allergy & Immune Bites
Allergy & Immune Bites
The gut is the immune system's training ground.
Two paths. One big difference.
Most anti-itch remedies suppress the immune system. We take the opposite path.
Suppress the symptoms
Cortisone and Apoquel dampen the immune response. That often eases symptoms quickly — but acts at the end of the chain. Once stopped, the itching can return. Such changes always belong in a vet's hands.
Strengthen the balance
Barklyn supports the immune system in finding its own balance again — through a healthy gut and targeted, researched actives. Not numbing, but balance from within.
Three stages to healthy skin from within.
1. Repair gut
Bovine colostrum supports the intestinal barrier, and the 6-strain complex builds a healthy gut flora. That is the foundation.
2. Modulating the Immune System
EpiCor® and Astragalus send signals to the immune system for a balanced rather than excessive response.
3. Keep your balance
Over weeks, the skin stabilizes from within — leading to less scratching, a calmer animal, and healthier fur.
Studies suggest a supportive role for gut barrier and immune function.
One of the most well-documented ferments; studies investigated, among other things, its immunomodulatory properties.
Its polysaccharides are a much-researched topic in immunological research.
The connection between the gut microbiome and the immune system is scientifically well-established.
