Nervous System
DOG FIT by PreThis® VITAMIN B
For nerves, drive, balance, and well-being in dogs.
Our needs-based and vegan supplement supports the normal function of nerves, organs, heart, muscles, and the back, as well as metabolism and the stimulus conduction of the urinary tract. Whether it is age, stress, or physical strain, sometimes dogs simply need extra support. The vegan VITAMIN B complex for dogs was developed specifically for this: for a targeted supply of valuable B vitamins.
It is particularly suitable for dogs with an increased need in the area of nerves, intervertebral discs, or the bladder, for example in cases of signs of aging, sensitive stimulus conduction, or in phases of high strain, as well as restlessness or nervousness (vagus nerve).
Skin, coat, mucous membranes, and energy balance are also supported in their normal function by the micronutrients contained. For more balance and quality of life, day after day.
- Developed with expert knowledge from animal health
- Vegan, non-GMO, without unwanted additives
- 60 capsules per pack for two months
- That is only from 0.37 € per day

DOG FIT by PreThis® VITAMIN B complex
Vitamin B complex for dogs » Needs-based and free from unwanted additives.
Supports the normal function of nerves, organs, heart, muscles, and the back, as well as metabolism and stimulus conduction of the urinary tract.
A well-supplied nervous system is crucial for a dog's quality of life. It controls movement sequences, coordination, muscle functions and much more. Our vegan Vitamin B complex supplements daily feeding with micronutrients valued in veterinary naturopathy to support normal function of the back, nerves, heart, organs, muscles and stimulus conduction to the urinary tract as well as metabolic processes.
DOG FIT by PreThis® VITAMIN B complex, developed with veterinarians, veterinary practitioners and nutritionists, is ideal for dogs with increased needs, e.g. in old age, after veterinary care or when the spine and intervertebral discs are stressed.
Especially with increasing age, the musculoskeletal system, the nervous system and the energy metabolism change. These changes place special demands on the nutrient supply.
Vitamin B complex
I am very satisfied with the products from Dogfit by Prethis. The vitamin B complex in particular has become part of the daily feed of our 8-year-old dog.

Targeted supplementation for nerves, stimulus conduction and vitality
The B-vitamins contained support physiological processes that are particularly in demand in everyday life and stressful situations:
- For normal nerve function in the area of the urinary tract: A targeted supplement can be useful, e.g. for special requirements of the urinary tract or stimulus conduction.
- For challenges in the back area: Supports the normal function of nerves and stimulus conduction, e.g. for dogs with increased stress on elastic structures such as the spine or adjacent connections.
- For the coordination of nerves and muscles: Accompanies physiological stimulus processing, e.g. in case of changed movement patterns or muscle tension.
- In situations of increased sensitivity to stimuli: In case of loud noises (New Year's Eve), training situations, dog encounters, stress or restlessness: a targeted supply of B-vitamins can be useful.
- For the vagus nerve: Supports the central "resting nerve" in signal transmission for relaxation and its normal nerve function.
- For normal cognitive functions: Attention, learning ability and mental alertness in everyday life or during challenges in old age.
- To support normal energy balance: Supplements feeding in case of fatigue or slowed movement behavior, for a more active dog life.
- To supplement the diet: In special phases of life or in case of nutritional increased demand for nerve-relevant B-vitamins.
- For skin, mucous membranes and coat: Supports the normal function of the skin and contributes to normal mucous membranes and a well-groomed coat.
- For normal energy metabolism: Accompanies needs-based energy production and supports your dog's vitality.
- For normal heart function: Contributes to the maintenance of the physiological function of the heart.
- For cell division and amino acid synthesis: Supports natural cellular processes and normal protein synthesis in the organism.
- In case of oxidative stress: Provides important micronutrients that contribute to normal cell function.

VITAMIN B » The power team of all 8 B-vitamins
These micronutrients contribute to the normal function of many areas, even in special phases with changed requirements.
Our complex contains the complete spectrum of B-vitamins: B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folic acid) and the high-quality B12 (methylcobalamin).
VITAMIN B » Competence for your dog's vitality
Developed in collaboration with experienced veterinary practitioners, veterinarians and nutritionists, our vegan Vitamin B complex offers needs-based and high-quality support for dogs. We rely on pure ingredients without unnecessary additives and the expertise from over 25 years of experience.
Recognizing signs of a B-vitamin undersupply
An undersupply of B-vitamins occurs more often than many think and often shows itself gradually. Since B-vitamins work closely together in the body, deficits rarely occur in isolation. Attention should be paid to the following signals:
- Vitamin B1 (thiamine): Can manifest through reduced appetite, changed eating behavior (e.g. eating feces), jumpiness or uncertainty in movement.
- Vitamin B2 (riboflavin) & B3 (niacin): An increased need often manifests in flaky skin, dull coat, sensitive lips or irregular digestion.
- Vitamin B5 (pantothenic acid): Important for pigmentation: an undersupply can favor graying and reduce coat quality.
- Vitamin B6 (pyridoxine): If this vitamin is lacking, it can lead to nervousness, general weakness and reduced resilience.
- Vitamin B7 (biotin): The classic for skin & hair. Signs of a need are brittle hair, hair loss, itching or skin irritation.
- Vitamin B12 (methylcobalamin): Essential for the nerves. A deficit often leads to listlessness, rapid fatigue and muscle weakness.
Why regular supply is so important:
Since B-vitamins are water-soluble, the body can hardly store them (except for B12). They must therefore be supplied regularly through food. With our DOG FIT by PreThis® VITAMIN B complex, supply gaps can be safely closed and a stable nervous system as well as pure vitality can be supported according to needs.
Tip: VITAMIN B is also available in a combo set with JOINTS, JOINTS elements, CARE senior or VITAL regeneration, cheaper than the two individual products at the regular price.

A real ray of hope
Horner's syndrome really had us worried. Thanks to the vitamin B complex, he's almost back to his old self after just a few weeks. His eye looks wide awake again, and the tremors have subsided. Top quality—worth every penny!

I've been using the vitamin B complex for over 3 months now and am very satisfied. His coat looks great, his skin has calmed down, and his movements seem more confident overall. My dog is a 6-year-old Rottweiler-German Shepherd mix from an animal shelter.

I've been giving my 15.5-year-old dog these vitamin B capsules for quite a while now (I mix the contents with quark), and despite her age, she's still full of energy and even learning new things :-) Thank you!

Questions
Which dogs is VITAMIN B intended for?
For adult dogs of any size and breed. We especially have in mind dogs that are to be supported in their daily feeding with the normal function of nerves and metabolism. VITAMIN B is a complementary feed for daily feeding and no substitute for a balanced diet. If your bitch is pregnant or nursing, or your dog is currently under veterinary treatment, please discuss supplementary feeding with your veterinary practice first. You will find the right size for your dog's weight under “Dosage instructions”.
Is VITAMIN B well tolerated, are there any side effects?
VITAMIN B is generally very well tolerated. We select our ingredients for high quality and a natural composition. As with any natural product, an individual dog may still react sensitively to a single ingredient. If you notice signs of intolerance, pause the supplement and get in touch with us. We are happy to help. If your dog has pre-existing conditions or receives a special diet or medication, please also talk to your veterinary practice.
When can I expect to see first results?
Give VITAMIN B regularly for at least six weeks, in some cases longer. How quickly you notice something varies from dog to dog and depends on your dog's individual needs. Natural formulations need time to unfold their supporting properties: regular feeding matters more than a high single dose.
How long does one pack of VITAMIN B last?
One pack contains 60 capsules and therefore lasts around two months with daily feeding. If your dog receives an extra capsule according to the dosage recommendation, it will last correspondingly less. For continuous feeding we offer value packs.
My dog won't eat the capsule: what can I do?
That can almost always be solved. Many dogs accept the capsule more readily when it is embedded in something soft: a spoonful of wet food, quark or a piece of liver sausage usually does the trick. If your dog doesn't like the capsule at all, you can also open it and mix the contents into the food. What matters most is regularity: an occasionally missed dose is no problem, but feeding should not be interrupted for long.
What makes VITAMIN B special?
Our DOG FIT by PreThis® VITAMIN B complex is a needs-based and purely vegan complementary feed, specially developed for the health and well-being of dogs. It is free from any unwanted additives, making it a safe and healthy choice.
The vitamin B complex plays a crucial role in supporting nerve regeneration and contributes to the normal function of the nervous system, particularly in dogs prone to restlessness. In addition, it serves as a general strengthening of the nervous system and contributes to improved health in dogs.
Its vegan formula makes it an ideal choice for all dogs, including those with sensitivities or special dietary needs. Rely on the DOG FIT by PreThis® VITAMIN B complex for an all-round vital and happy four-legged friend who shines from the inside out and is full of joy of life.
What is methylcobalamin?
Methylcobalamin is an active form of vitamin B12. DOG FIT by PreThis® VITAMIN B contains B12 in this form, together with the seven other B vitamins B1, B2, B3, B5, B6, B7 and B9.
Can I also give VITAMIN B preventively?
Yes, the use of the DOG FIT by PreThis® VITAMIN B complex is also highly recommended as a precaution. The valuable B vitamins play a central role in numerous metabolic processes and are particularly indispensable for a healthy nervous system.
Precautionary supplementary feeding of the VITAMIN B complex can help maintain and strengthen dogs' nerve health. This is particularly important because a well-functioning nervous system is the basis for vitality, well-being and a high quality of life for four-legged friends.
Regular supplementary feeding can support nerve health in the long term and accompany your dog in his active and happy life.
