You should seek the advice of your veterinarian if your pet is ill as only he or she can correctly advise on the diagnosis and recommend the treatment that is most appropriate for your pet.

The scientific evidence to support the administration of nutritional supplements to pets is often very weak. Best evidence are randomised controlled trials (RCTs)

Manganese (n=1 RCT - in a mixture)

In one RCT in which manganese was present as a component of a commercially available mixture with glucosamine and chondroitinc  (Moreau 2003) (n=23)  there was no improvement in signs of OA based on objective (ground reaction forces) measurements or subjective owner and veterinary assessment.

Evidence : WEAK No effect
