almapharm astoral B-DecapleX h.a. contains specific nutrients and active ingredients to compensate for a temporarily and/or permanently increased need to promote and support the function of overall metabolism. Dogs may have an increased need for reduced metabolic activity due to situation or age.
When should you use astoral/astorin B-DecapleX h.a. support? During convalescence, neurological disorders, skin and coat problems, when feeding self-prepared food, in stressful situations, during pregnancy, in the growth phase
Vitamins cannot be produced by the body itself, so they must be taken with food and/or with food supplements. Vitamins strengthen the immune system, promote healthy growth and a beautiful coat. They are important for the brain and nerve metabolism. Each vitamin has its own tasks!
B vitamins - certain vitamins are stored in the body, the animal can eat them in stock. Other vitamins, in turn, cannot be stored, but must be supplied continuously via the food. Thus, the vitamins can be divided into two groups: the fat-soluble, storable vitamins, and into the water-soluble, non-storable vitamins. The B vitamins are one of the water-soluble vitamins and cannot be stored in the body.
An excess is excreted through the urine. Thus, the animal is therefore dependent on a regular supply from the outside. However, there is also no need to worry about oversupply. The group of B vitamins includes the following eight vitamins: vitamin B1 (thiamine), vitamin B2 (ribofl avin), vitamin B6 (pyridoxine), vitamin B12 (cobalamin), biotin (vitamin B7), pantothenic acid (vitamin B5), folic acid (vitamin B9) and nicotinic acid (niazin). .
