AcidBuf for Horses – Advanced Digestive Support & Mineral Supplement

AcidBuf for Horses is a premium equine supplement designed to support digestive health while delivering a highly bioavailable source of calcium and magnesium. Derived from the calcified skeletal remains of red seaweed (Lithothamnion calcareum), this natural ingredient is sustainably harvested from the pristine, mineral-rich waters of Iceland and southwestern Ireland.

Superior Structure for Enhanced Performance

Unlike traditional calcium carbonate, AcidBuf features a unique open, porous “honeycomb” structure. This significantly increases its surface area, allowing for greater interaction with stomach acids and digestive juices. The result is improved buffering capacity and more efficient mineral absorption. Studies have shown that supplementation with AcidBuf can lead to enhanced calcium uptake and improved bone density compared to standard calcium sources.

Supports Strong Bones & Muscle Function

With a naturally balanced composition of calcium and magnesium, AcidBuf promotes healthy skeletal development, maintenance, and overall muscle function—key factors for performance, growth, and wellbeing in horses of all ages.

Effective Gastric Buffer for Ulcer Management

AcidBuf acts as a powerful natural antacid, helping to neutralise excess stomach acid and reduce irritation associated with gastric ulcers. This is particularly beneficial for performance horses, where stress, diet, and training intensity can increase the risk of Equine Gastric Ulcer Syndrome (EGUS). By maintaining a more stable stomach pH for longer periods, AcidBuf helps protect the stomach lining and supports digestive comfort.
