The Multi-Glandular Support supplement from Best for Your Pet is designed to support the overall health and function of your pet's glands, particularly the endocrine system. This type of supplement typically contains a blend of glandular tissue from various animal sources, which is believed to help provide nutritional support to your pet’s glands and organs (such as the liver, thymus, and spleen) of animals like cows or pigs), improving their health and function. The idea behind glandular supplements is that these organ extracts provide bioavailable nutrients and enzymes that can help your pet’s own organs perform at their best.
