Vetri-Science Vetri-DMG Liquid
Vetri‑Science Vetri‑DMG Liquid is notable for its distinct technical approach: a liquid DMG formulation derived from yeast that offers flexible dosing and rapid administration for animals, making it a go‑to when precise or adjustable dosing is required rather than a straight beta‑glucan supplement. It complements the list by providing an alternative immunomodulatory mechanism to beta‑glucans—trading the chewable/tablet convenience of NaturVet and NOW Pets and the clinical standardization of Thorne for liquid versatility and targeted use.
