Why NASC membership matters to your horse

MVP is a founding member of the NASC (National Animal Supplement Council), and every formula undergoes third-party testing to ensure purity, potency and label accuracy. The company is committed to building trust through transparency, so the amount listed on the label is exactly what your horse is receiving. For a directory of supplements where ingredient claims are too often unverified, that audited, founding-member status is a meaningful mark of quality.
