Ingredients & Functions
MCT Oil (C8/C10)
MCT oil provides rapidly available energy from medium-chain fatty acids (caprylic acid C8 and capric acid C10). These fatty acids are particularly easy to digest and are directly utilized by the body. In canine nutrition, MCT oil can support energy supply and contribute to vitality and mental performance.
Liquid Sunflower Lecithin
Sunflower lecithin is a natural source of valuable phospholipids, which play an important role in cell membranes and fat metabolism. As a natural emulsifier, lecithin also improves the absorption of fat-soluble nutrients, thus supporting optimal nutrient utilization in the dog's organism.
Marine Oil (Fish Oil, Refined)
Refined fish oil provides high-quality omega-3 fatty acids, especially EPA and DHA. These essential fatty acids support skin and coat, can promote anti-inflammatory processes in the body, and contribute to normal heart and brain function in dogs.
Refined Olive Oil
Olive oil is rich in monounsaturated fatty acids and natural antioxidants. It supports energy metabolism, can contribute to skin and coat health, and supplements the fatty acid supply in the daily diet of dogs.
Milk Thistle Oil (Lipophilic Extract)
Milk thistle oil contains valuable plant compounds from milk thistle, traditionally used to support liver function. In canine nutrition, the extract can promote natural metabolism and contribute to supporting liver health.
Glycerin (Food Grade)
Food-grade glycerin serves as a carrier for nutrients and supports a stable product formulation. It ensures that the ingredients are evenly distributed and contributes to a pleasant consistency of the recipe.
Vitamin A
Vitamin A is an essential vitamin for numerous bodily functions in dogs. It supports eyesight, strengthens the immune system, and contributes to the health of skin, mucous membranes, and cell growth.
Vitamin D3
Vitamin D3 plays an important role in calcium and phosphorus metabolism. It supports the building and maintenance of strong bones and teeth and simultaneously contributes to normal immune system function.
Vitamin E
Vitamin E is a powerful antioxidant that protects cells from oxidative stress. In canine nutrition, it supports the immune system, contributes to skin and coat health, and protects sensitive fatty acids in the body.
Rosemary Extract
Rosemary extract is a natural, plant-based antioxidant. It protects sensitive oils from oxidation and helps to maintain the freshness and stability of the product.

Facts
Bacillus Subtilis supports your dog's natural gut flora, thus contributing to balanced digestion and increased well-being in everyday life.
The probiotic bacterial strain works specifically in the digestive tract and supports the natural balance in the gut of dogs.
Thanks to its special spore form, Bacillus Subtilis is resistant and reaches your four-legged friend's intestine in a stable, effective form.
Bacillus Subtilis helps to promote the natural balance in the gut and creates conditions in which "good" gut bacteria can thrive.
By supporting natural digestive processes, Bacillus Subtilis can help improve nutrient absorption.
Studies show that Bacillus Subtilis can support the natural intestinal barrier – an important foundation for your dog's internal balance.
Via the gut, Bacillus Subtilis can gently support dogs' natural immune systems without overstimulating them.
Especially during stressful periods, such as changes in diet or daily routines, a stable intestinal flora can contribute to balance.
A more stable digestive system is often reflected in firmer stool consistency and less odor – a plus for both dog and owner.
Frequently Asked Questions
You can find more questions and topics in our help center .
What are BSN® Bacillus subtilis products for dogs?
BSN® Bacillus subtilis products are probiotic food supplements for dogs, specifically formulated to support intestinal health, gut health, and overall well-being. The Bacillus subtilis strain they contain is naturally occurring and scientifically researched.
For which dogs are probiotics suitable?
BSN® products are suitable for dogs of all breeds, sizes, and ages – from puppies to senior dogs. They can be used both for daily support of intestinal health and during sensitive phases such as dietary changes, stressful situations, or in old age.
How do our dog probiotics work?
Probiotics contain live microorganisms that support the gut, a central organ for overall well-being. They promote a stable gut environment and create conditions in which beneficial gut bacteria can thrive. A balanced gut flora can have a positive effect on digestion, nutrient absorption, and overall well-being.
What is Bacillus subtilis and why is it used for dogs?
Bacillus subtilis is a spore-forming, probiotic bacterial strain. Its natural resilience allows it to reliably reach the intestines. In animal nutrition, Bacillus subtilis is used to support the intestinal flora and maintain the natural balance of the digestive system.
How do I give my dog BSN® products?
The products are available as a powder or liquid (drops) and can be easily mixed into your dog's daily food. The exact dosage depends on the product and your dog's weight. Application is straightforward and practical for everyday use.
When can I expect to see an effect?
Supporting gut health is a process-oriented, long-term approach. Initial changes may be noticeable individually, depending on the dog. Generally, regular, continuous use over several weeks is recommended to allow the gut time to stabilize.
Can the products be given continuously?
Yes, BSN® Bacillus subtilis probiotics are designed for long-term use. They are suitable for both the continuous support of gut health and for temporary periods of special need.
Are the products also suitable for sensitive dogs?
The formulas are intentionally mild and well-tolerated, and free from unnecessary additives. Nevertheless, it is recommended to introduce new products gradually, especially to very sensitive dogs.
Are the products laboratory tested?
Yes. All BSN® products are laboratory tested to ensure consistently high quality, purity, and safety.
Can the products be administered together with medication?
In general, dietary supplements can be used as a complementary treatment in many cases. However, if your dog has existing medical conditions or is regularly taking medication, we recommend consulting your veterinarian before using them.
Are these products a medicinal product?
No. BSN® Bacillus subtilis products are dietary supplements for dogs. They provide nutritional support and do not replace veterinary diagnosis or treatment.
Are side effects possible?
The products are generally well tolerated. In rare cases, sensitive dogs may experience temporary digestive upset. If any abnormalities persist, a veterinarian should be consulted.
Can I combine multiple BSN® probiotics?
Yes, the products are designed to be easily integrated into everyday life. If you are unsure about combining different supplements, we recommend a personal consultation.
Are the products suitable for long-term gut health?
Yes. BSN® Bacillus subtilis products are designed for sustainable, long-term support of intestinal health – not as a short-term solution, but as continuous support for your dog's well-being.
