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.
A large share of immune cells reside in the gut-associated lymphoid tissue. This is where the body learns every day to tell harmless substances from dangerous ones.
When the gut flora falls out of balance or the gut barrier becomes permeable (often called “leaky gut”), the immune system can overreact. This frequently shows up as itching, skin problems or allergic reactions.
That's why true skin health doesn't start on the skin — it starts in the gut.
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. Supporting the immune system
Dried yeast fermentate and astragalus root support the immune system.
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.
Its polysaccharides are a much-researched topic in immunological research.
The connection between the gut microbiome and the immune system is scientifically well-established.
