NOT NECESSARILY.
Gas, crying or fussiness can have many causes. These symptoms alone cannot confirm an allergy—or tell us that A1 protein is responsible.

Possible symptoms include:
• Hives, swelling or worsening eczema
• Repeated vomiting or diarrhoea
• Blood in the stool
• Feeding difficulties or poor growth
• Breathing difficulty or a severe allergic reaction
Symptoms vary, so CMPA requires proper medical assessment.
IMPORTANT:
A2 formula and goat-milk formula are NOT treatments for CMPA.

B: A1-FREE FORMULA AND DIGESTIVE COMFORT
🥛 A1 and A2 beta-casein are digested differently.
A1 beta-casein can release a peptide called BCM-7 during digestion. Researchers are studying whether this affects digestive comfort in some infants.
A 2025 trial involving healthy, mixed-fed infants found similar growth and fewer reported digestive symptoms and crying episodes with an A1-free formula compared with conventional formula.
However, this was one open-label study. It did NOT prove that A1 protein causes every baby’s discomfort—and it did not test goat formula as a treatment for CMPA.
📌 REMEMBER:
CMPA = IMMUNE REACTION
A1/A2 = TYPE OF BETA-CASEIN
THEY ARE NOT THE SAME ISSUE
Don’t diagnose CMPA or repeatedly change formula based only on gas or crying.
If symptoms persist—or your baby has blood in the stool, repeated vomiting, poor feeding or poor growth—seek professional assessment.
Breathing difficulty, collapse or significant facial swelling requires emergency care.
