Product information: The addition of biotin plays an important role in the maintenance of your dog or cat's skin, hair and coat. Biotin deficiency can lead to a dull coat and chapped skin. Biotin is a water-soluble and sulfur-containing essential vitamin (H or B7) that is present in very low concentration in nature. Research has shown that additional biotin in the feed strengthens the skin and hair and protects them from external influences. Dosage: Mix 1 level measuring spoon (measuring spoon: 3 ml= 1.5g; 5 ml = 2.5 g; 8 ml = 4 g) per day with dinner or kibble, preferably divided over two daily periods. In case of poor coat condition, double the dosage for 4 to 6 months and then change to the normal dosage.
