Very recently, there has been some confusion among a limited number of members of the public regarding bovine colostrum, an ingredient in several ImmuBiome products.

The Facts

• ImmuBiome’s products were subject to rigorous review and testing before introduction into the market.
• Over the past eight years, more than 40,000 competitors, including Olympians and FEI riders subject to testing, have used ImmuBiome products, with zero positive tests for banned or prohibited substances.
• During the same eight years, there have been zero (0) positive tests for any banned or prohibited substances found in any ImmuBiome product.

Bovine Colostrum

• Some ImmuBiome products contain unadulterated bovine colostrum, but ImmuBiome does not add any ingredients to the colostrum.
• The ingestion of bovine colostrum in ImmuBiome products does not lead to impermissible amounts of alpha-casozepine.
• Bovine colostrum contains small and varying amounts of milk protein, the digestion and metabolic use of which can produce minuscule, trace amounts of alpha-casozepine.
• To date, none of the 40,000 riders using ImmuBiome products has tested positive for a prohibited or banned substance that was found to have come from ImmuBiome products.

Unfortunately, in this internet era, confusion and misunderstanding can easily proliferate into unsupported statements. Should you have any question or concern regarding the safety or contents of ImmuBiome’s products, for a prompt response, please contact ImmuBiome at hello@immubiome.com.

No, we never use sweeteners.

Research indicates that consuming foods high in sugar, like molasses, can trigger inflammation. This happens because sugary foods cause a spike in insulin, leading to a chain of biochemical reactions that result in inflammation. Most aches and pains are linked to inflammation, and even if pain stems from trauma, it can be worsened and prolonged by eating high-sugar foods.

At ImmuBiome, quality is our top priority. As fellow horse enthusiasts, we believe that our cherished equine partners and athletes deserve the best possible quality of life. We are committed to ensuring their health and well-being, and we take pride in making a positive impact across the industry. Our dedication to quality begins with the development of our formulas, using only the highest quality, most bioavailable raw ingredients to create safe and effective products. Each batch is independently tested for potency, purity, and contaminants, ensuring the highest standards for our equine companions.

Colostrum offers unparalleled benefits compared to any other protein supplement. While both colostrum and whey protein can help build lean muscle, colostrum does so more quickly and provides additional advantages that whey cannot. Bovine colostrum, in particular, is considered one of the world's most powerful superfoods. Naturally designed to maintain health and prevent disease, it supports immune function in the gut, aids tissue repair, and promotes lean muscle growth. Colostrum has been shown to significantly reduce gut permeability ("Leaky Gut"), stimulate normal cell growth and regeneration, and accelerate the healing of muscle, cartilage, and bone. We responsibly source human-grade, bio-active, cold-pressed colostrum to ensure the highest quality for our four-legged athletes.

We recommend ImmuBiome Lean Muscle for horses with insulin resistance and those suffering from Cushing's Disease. This formulation contains a high concentration of colostrum, known to help balance blood sugar levels and support muscle development—both critical factors for managing IR and Cushing’s horses.

Yes, ImmuBiome products can be safely fed alongside other supplements. However, because our formulas are packed with superfood ingredients, they already provide highly bioavailable nutrition. Beyond a quality electrolyte like sea salt or Redmond salt and your horse’s regular feed, our supplements are designed to comprehensively support your horse’s overall health.

Most horses are drawn to ImmuBiome due to its sweet aroma, but for picky eaters, we recommend a gradual introduction. Start with ¼ to ½ scoop mixed well into moist feed for a few days, then gradually increase to the full scoop.

Good Manufacturing Practices (GMP) are standards that ensure products are consistently produced with high quality and safety for their intended use. If a facility does not comply with GMPs, its products may be deemed adulterated and unsafe. In the U.S., the Food & Drug Administration (FDA) enforces GMPs for the production and sale of food, beverages, dietary supplements, pharmaceuticals, and cosmetics. The “c” in cGMP stands for "current," indicating that companies must continuously update their practices based on the latest scientific research and industry standards. Maintaining these high standards is our top priority.
