Regardless of whether your pet is primarily fed dry food, wet food, or a BARF diet, biotin is usually already present in some form in the food. Nevertheless, in specific situations—for example, during shedding season in long-haired dog breeds and cats—it can be beneficial to supplement biotin intake with a suitable feed supplement. During such phases, many owners find it important to adjust their pets nutritional profile to meet their specific needs. In addition to biotin, this product provides MSM, an organic sulfur compound traditionally used in animal feed to enrich the daily nutrient supply with sulfur-containing components. Many pet owners value MSM as a building block to round out the feed ration, especially when specific nutritional needs are being addressed. In certain cases, the biotin content in the food may be insufficient to meet the individual needs of the animal. This can be reflected, for example, in the appearance of the coat. Brittle, dull fur, increased hair loss, dry skin, dandruff, or brittle claws are often considered by pet owners to indicate that the diet should be examined more closely. Targeted supplementation with biotin plus MSM can be an option in such situations to optimize the daily food composition. The biotin requirement of dogs and cats is also increased during specific life phases such as pregnancy and lactation. A tailored, time-limited course of treatment with a higher dosage of this nutrient can then help meet the specific needs of these life stages. This allows for flexible adjustment of the diet to the respective circumstances.
