FAQs

Help center

Good Fitness soft chews bring together myHMB®, Carniking® L-Carnitine, and Vitamin D3 — ingredients backed by veterinary science to support lean muscle, fat metabolism and vitality.

Over 59% of dogs in the U.S. are overweight, and as dogs age or become less active, their bodies naturally lose muscle and store more fat — a combination that can reduce mobility, energy, and quality of life. Good Fitness is a triple-action formula designed to work from the inside out.

Here's what Good Fitness does:

  • Helps maintain and build lean muscle mass
  • Supports muscle recovery and regeneration after activity
  • Helps combat age-related muscle loss
  • Aids in reducing body fat while preserving muscle integrity
  • Supports metabolism and promotes efficient fat-to-energy conversion
  • Promotes strength, mobility, and vitality at every life stage

Good Fitness is manufactured in the USA from globally sourced ingredients.

Each soft chew is approximately ¾ of an inch.

Good Fitness comes in a peanut butter flavor your dog will love. In case of picky eaters, you may break up the soft chew and sprinkle it in their food.

You may give Good Fitness to dogs of all ages and life stages. The formula is especially beneficial for senior dogs, overweight dogs, and canine athletes. When in doubt, consult your veterinarian before giving any new supplement to your dog.
