Owners understandably want a dose. But because products vary by source, purity, and labeling, it’s not responsible to generalize a one-size number. The better approach is to follow the manufacturer’s directions and ask your veterinarian to sanity-check the plan against your dog’s size, diet, and medical history. In research settings, different inclusion levels have been tested in healthy adult dogs, with measurable changes in microbiome and related variables (Marchi PH, 2024).
If you’re using a beta glucans powder for dogs, consistency matters more than intensity. Start low, go slow, and keep everything else stable for two to three weeks so you can interpret what you’re seeing. If your dog is on immune-modifying medications, treat dosing as a shared decision with your clinic.
