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.

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.

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.
