Frequently asked questions

Does my cat need a multivitamin, vitamin, or mineral supplement?

The average modern cat diet does not contain enough vitamins, minerals and essential fatty acids to support a cat's long-term health. In addition, over time, your cat will produce less and be able to absorb less essential nutrients on his own. By supplementing your cat's food with a multivitamin, like Spectrin, you give you cat the best possible chance at full nutrition and a full life. Spectrin multivitamin for cats is easy to use and should be used daily for best nutrition.

Why is Spectrin a recommended multivitamin for cats?

While many pet supplements are simply human supplements with a pet label; Spectrin is a powerful multivitamin formula made specifically for your cat. Spectrin supplies the perfect balance of essential vitamins and minerals, specialized amino acids with the added benefit of Glucosamine, Chondroitin, and MSM for joint, skin and coat  supportOur formula includes premium, chelated minerals and citrus bioflavonoids for superior absorption of all nutrients. Spectrin is the number one choice multivitamin for cats and mineral supplements.

Our ingredients are manufactured in the USA without use of dairy, soy, wheat, or other allergens. Spectrin multivitamin for cats is manufacured under the highest GMP standards, and, with Nusentia's 60 day 100% money back guarantee, you can rest assured that you've made the right choice for your cat.

Can Spectrin multivitamin for cats help also with allergies?

Yes, Spectrin multivitamin for cats has significant targeted nutrition to combat allergies and to promote a vibrant skin and coat. One of the most common health challenges in cats are problems related to the skin. These conditions are often caused by allergies. Substances which can cause an allergic reaction in dogs are much the same as those which cause reactions in people including pollens, dust mites and molds, and intake of specific foods.

How do I know if my cat has allergies?

If your cat is showing any of these signs then they are likely to benefit from a skin and coat formula and multivitamin for cats:

  • Does your cat constantly scratch itself?
  •  Does your cat sneeze or cough often?
  •  Does your cat have any swelling of the eyes or mouth?
  •  Does your cat have rashes on the head, back or neck?

Will my cat like the liquid/flavor?

Our experience is that cats love the flavor of the liquid multivitamin as the product is specifically designed with cat’s in mind. An added benefit is pet owners love the convenience!

Can I use Spectrin for Cats with other supplements?

Yes. Spectrin multivitamin for Cats is designed to provide the foundational nutrition your cat needs for superior wellness. It also includes additional nutrients for joint support, and for promotion of a vibrant skin and coat. For more advancing issues such as joint immobility or GI distress targeted supplements such as Regenex -Joint Support , Probiotic Miracle-GI Support, or Celavin -Ultra pure fish oil can be used in conjunction for a dynamic program to improve your cat’s health.

Can I give Spectrin for Cats to my kitten or young cat?

Yes the product is safe for use as a multivitamin for kittens and young cats. Make sure to follow the dosing guidelines provided on the bottle, which are based on body weight.
